Answer:

0.59 cm

Explanation:

height of cup (h) = 10 cm

radius of cup (r) = 10 cm

rate of change of water level (V') = 16π/3 [tex]cm^{3} /sec[/tex]

rate of change of height (h) = 3 cm

the ratio of the height to radius (h:r) = 10:10

h/r = 10/10

h/r = 1

r=h

formula for volume of a volume (v) = [tex]\frac{1}{3}[/tex].π[tex]r^{2}[/tex]h

substituting r=h into the formula above we have

v = [tex]\frac{1}{3}[/tex].π[tex]h^{2}[/tex]. h = [tex]\frac{1}{3}[/tex].π[tex]h^{3}[/tex]

differentiating the above we have

v' = 3([tex]\frac{1}{3}[/tex]π[tex]h^{2}[/tex])h' = π[tex]h^{2}[/tex].h'

rearranging the above we have

h' = v' / (π[tex]h^{2}[/tex])

where

h' = ((16 x π) / 3) ÷ ( π x [tex]3^{2}[/tex])

h' = ((16 x 3.142) / 3) ÷ ( 3.142 x [tex]3^{2}[/tex])

h' = 16.76 / 28.28

h' = 0.59 cm

Answer: The oscilloscope is not a plotting machine.

Explanation: The Oscilloscope is not a plotting machine is a device which is use to measure the frequency,period, peak to peak Voltage Vpp or any signal. That is alternating.

So, if you're such you wired your circuit whose output signal you want to measure very well and all connections and settings are done accurately, then you can reduce the volt/div below 0.2. You not seeing any signal at 0.2v/div shows that the amplitude of the signal coming into the Oscilloscope is not up to that.

The x-axis on an oscilloscope represents time, while the y-axis represents voltage. To view a 6 volt signal when the 'volts/div' is set at 0.2, you should adjust it to 2 volts/div or higher, as the current setting is too low to display the signal's amplitude correctly.

On an oscilloscope, the horizontal axis (or x-axis) typically represents time, allowing you to see how a signal changes over time. The vertical axis (or y-axis) represents voltage, displaying the amplitude of the signal. If you are attempting to view a 6 volt signal with the "volts/div" setting at 0.2 volts per division, the signal will be off-scale, because each division will represent only 0.2 volts, and a 6 volt signal would require 30 divisions to be fully displayed, which is beyond the scope of a standard oscilloscope screen.

To properly view the 6 volt signal, you should turn the dial to 2 volts/div or higher. This adjustment will ensure that the signal occupies fewer divisions on the screen, making it visible. If you set it to 0.02 volts/div, the signal would be even less visible because the signal would then require 300 divisions, which is impractical to display.

Answer:

option (c)

Explanation:

When an object thrown upwards, the value of acceleration acting on the object is acceleration due to gravity which is always acting towards the earth.

As it falls downwards, the acceleration is again equal to the acceleration due to gravity.

So, the ball's acceleration is constant.

Final answer:

The acceleration of the ball remains constant throughout its up and down motion since it is solely influenced by gravity, which provides an acceleration of approximately 9.81 m/s² downward

Explanation:

When a ball is thrown upwards from the ground and then falls back down, the acceleration of the ball is what remains constant throughout its motion. This is due to gravity, which acts downward on the ball with an acceleration denoted as "g". While the ball's position and speed are changing throughout the motion, its acceleration due to gravity remains constant at approximately 9.81 m/s2 (on Earth), regardless of its state of motion. Therefore, the quantity that remains constant over the course of this up and down motion is the ball's acceleration.

Answer:

spring constant of the spring will be equal to 317.33 N/m

Explanation:

We have given mass of the child m = 6.80 kg

Spring is stretched by length of 0.210 m . so x = 0.210 m

Acceleration due to gravity [tex]g=9.8m/sec^2[/tex]

Force on the child will be equal to [tex]W=mg[/tex]

This force will be balanced by spring force

And spring force is equal to F = Kx

So kx = mg

[tex]k\times 0.210=6.80\times 9.8[/tex]

k = 317.33 N /m

So spring constant of the spring will be equal to 317.33 N/m

Answer:

P = 7.28 N.s

Explanation:

given,

initial momentum of cue ball in x- direction,P₁ = 9 N.s

momentum of nine ball in  x-  direction, P₂ = 2 N.s

momentum in perpendicular direction i.e. y - direction,P'₂ = 2 N.s

momentum of the cue after collision = ?

using conservation of momentum

in x- direction

P₁ + p = x  + P₂

p is the initial momentum of the nine balls which is equal to zero.

9 + 0  = x  + 2

x = 7 N.s

momentum in x-direction.

equating along y-direction

P'₁ + p = y + P'₂

0 + 0 = y + 2

y = -2 N.s

the momentum of the cue ball after collision is equal to resultant of the momentum .

[tex]P = \sqrt{x^2+y^2}[/tex]

[tex]P = \sqrt{7^2+(-2)^2}[/tex]

      P = 7.28 N.s

the momentum of the cue ball after collision is equal to P = 7.28 N.s

The momentum of the cue ball after the collision is calculated to be 6.2 N·s in based on the conservation of momentum.

This physics problem involves the principle of conservation of momentum. Initially, the cue ball has a momentum of 9.0 N·s. After the collision, the nine-ball has a momentum of 2.0 N·s in the original direction and another 2.0 N·s in a perpendicular direction. To find the momentum of the cue ball after the collision, we need to take into account that the total momentum of the system is conserved before and after the collision.

In this case, the total initial momentum is the momentum of the cue ball, which is 9.0 N·s. After the collision, the total momentum should still be 9.0 N·s. The sum of the momenta of the nine-ball (which is the square root of the sum of the squares of the two momentum components, due to the Pythagorean theorem) is 2.8 N·s. Therefore, the momentum of the cue ball after the collision will be the total initial momentum minus the momentum of the nine-ball after the collision, which gives us 9.0 N·s - 2.8 N·s = 6.2 N·s.

To solve this problem, we can use the principle of conservation of momentum. Before the collision, we have the momentum of the cue ball which is 9.0 N·s. After the collision, we have the momentum of the nine-ball which is 2.0 N·s in the original direction of the cue ball and 2.0 N·s perpendicular to that direction. Since momentum is conserved, the total momentum before the collision is equal to the total momentum after the collision. Therefore, the momentum of the cue ball after the collision is the difference between the total momentum before the collision and the momentum of the nine-ball after the collision.

To calculate the momentum of the cue ball after the collision, we subtract the momenta of the nine-ball from the initial momentum of the cue ball. The momentum of the cue ball after the collision is therefore 9.0 N·s - (2.0 N·s + 2.0 N·s) = 5.0 N·s in the original direction of the cue ball.

Final answer:

To find the vector sum of the electric forces exerted on particle 3, we need to calculate the electric force between particle 3 and both particle 1 and particle 2. The electric force between two charges is given by Coulomb's Law. By plugging in the charges and distances, we can calculate the electric forces and find the vector sum.

Explanation:

To find the vector sum of the electric forces exerted on particle 3, we need to calculate the electric force between particle 3 and both particle 1 and particle 2. The electric force between two charges is given by Coulomb's Law:

F = k * (|q1| * |q2|) / r^2

Where F is the electric force, k is the electrostatic constant, q1 and q2 are the charges, and r is the distance between the charges. Since particle 1 is fixed at the origin, the distance between particle 3 and particle 1 is |-4.0 m| = 4.0 m. Similarly, the distance between particle 3 and particle 2 is |4.0 m - (-4.0 m)| = 8.0 m. Plugging in the values, we can calculate the electric forces between particle 3 and both particle 1 and particle 2.

Let's calculate:

F3-1 = (9 * 10^9 N.m^2/C^2) * (|-4.0 μC| * |8.0 μC|) / (4.0 m)^2

F3-2 = (9 * 10^9 N.m^2/C^2) * (|-4.0 μC| * |8.0 μC|) / (8.0 m)^2

Now, we can find the vector sum of the electric forces by adding the x-components and the y-components of both forces.

Answer: A. Vb1 = -6m/s , Vb2 = 9m/s.

B. Vb1 = 4.5m/s , Vb2 = 4.5m/s

Explanation: A. In a perfectly elastic collision the objects involved moved with a different velocity after collision. Also kenitic energy is conserved. In other to get the different velocity of ball 1 (Vb1) and ball 2 (Vb2) after collision, we apply the following formula

Vb1 = {{m1 - m2}*V1}/{m1 +m2}

Vb2 = {{2m1}*V1}/{m1 + m2}

Where V1 = velocity of ball 1 before collision=15m/s

m1 = mass of ball 1

m2 = mass of ball 2.

Substituting in the above equation:

Vb1 = {{0.15kg - 0.35kg}*15}/{0.15 + 0.35}

= {{-0.2}*15}/0.5

= -3/0.5

= -6m/s

Also,

Vb2 = {{2*0.15kg}*15m/s}/{0.15kg + 0.35kg}

={0.3kg*15m/s}/0.5kg

=4.5/0.5

=9m/s

B. In a perfectly inelastic collision the object involved move with a common velocity after collision.

We have that ,

m1*V1 + m2*v2 = {m1 + m2} V¹

Where V¹ is the final velocity of both balls after a perfectly inelastic collision.

NOTE: v2 here is 0m/s since ball 2 was at rest before collision.

So we have,

0.15kg*15m/s + 0.35kg*0m/s = {0.15kg + 0.35kg}*V¹

2.25 kgm/s = 0.5kg* V¹

Making V¹ subject of formula we have,

V¹ = 2.25kgm per sec/0.5kg

=4.5m/s. vb1 = Vb2 = V¹

NOTE also that the mass of the balls from the question were given in gram hence we converted to kilogram the standard unit for mass by dividing by 1000.

Explanation:

Weigh of floating ball=5.5 N

Acceleration due to gravity=9.8 [tex]m/s^2[/tex]

We have to find the size of the buoyant force that acts on it.

We know that

Buoyant force is that force which act in upward direction and exert by fluid and opposes the weight of an immersed object.

Therefore,

Buoyant force=Weight of ball

Buoyant force=5.5 N

Hence, the size of buoyant force acts on the ball=5.5 N

Given the ball's weight of 5.5 N, the buoyant force is also 5.5 N.

To determine the buoyant force acting on a floating ball, we can use the principles of buoyancy and the given information about the ball's weight. The ball's weight in air is 5.5 N, and we know the acceleration due to gravity (g) is 9.8 m/s².

For a floating object, the buoyant force (Fb) is equal to the weight of the object when it is floating. Therefore, since the ball is floating, the buoyant force must equal the weight of the ball:

Buoyant force Fb = Weight of the ball

Given that the weight of the ball is 5.5 N, the buoyant force acting on the ball is:

Fb = 5.5 N

This force is what keeps the ball afloat in the fluid.

Part A. The initial speed of the egg is 17.7 m/s.

Part B. The maximum height of the egg is 15.98 m.

Part C. The magnitude of the velocity at its highest point is 0 m/s.

Part E. The magnitude and direction of the acceleration in the upward direction is 9.8 m/s2.

Given that the distance traveled by the egg is 34 m in time 5 seconds.

The distance at its initial point will be zero.

The initial speed of the egg can be calculated by the position equation of the egg.

If the current flowing in two wires is I and they are separated by a distance of d. We know that the magnetic field due to a wire is given by :

[tex]B=\dfrac{\mu_oI}{2\pi d}[/tex]

Where

d is the separation between wires

The magnetic force between the wires is given by :

[tex]F=BIL[/tex]

I is the current in wire

L is the length of the wires

[tex]F=\dfrac{\mu_oI^2L}{2\pi d}[/tex]

The magnetic force per unit length is given by :

[tex]\dfrac{F}{L}=\dfrac{\mu_oI^2}{2\pi d}[/tex]

So, the force per unit length F/L between the two wires is [tex]\dfrac{\mu_oI^2}{2\pi d}[/tex]. Hence, this is the required solution.

Answer:

True

Explanation:

It can cause flooding and destruction of habitat because of dammed rivers create large reservoirs upstream which can spill out to the surrounding during heavy rainfall causing flooding and destruction of natural habitat.
