In the laboratory, a ball is dropped onto a force-sensing platform several times, each time hitting a different surface (foam, f
NeX [460]

Answer:

Graphing the momentum against the change in moment yields a linear relationship.

Explanation:

This is an impulse experiment,

          I = ∫ F .dt

where the force and time of the collision are measured, therefore if we assume an average force the integral reduces to

           I = F t

Furthermore, the momentum is equal to the change in moment of the ball, this change in moment can be found using the energy relations measuring the height of the ball and calculating its speed, in the two intervals for the descent and for the exit, possibly the heights are different so the moment change is different from zero.

Starting point. Higher

          Em₀ = U = mgh

Lower end point, just before hitting the scale

          Em_{f} = K = ½ m v²

in the path in the air there is no friction

          Em₀ = Em_{f}

          m g h = ½ m v²

          v = \sqrt{2gh}

this height is different for the descent and ascent of the ball, so we have two moments

         Δp = p_{f} - p₀

         Δp = m (v_{f} -v₀)

         

therefore we have the relationship

         

         I = Δp

Graphing the momentum against the change in moment yields a linear relationship.

When a substance changes from one phase to another, which of the following events occurs?
mojhsa [17]

Heat is transferred when a substance changes phases. Substances can be made to change phases by fluctuating the temperature, the pressure, or both. I hope I could help!

How many excess electrons must be distributed uniformly within the volume of an isolated plastic sphere 23.0 cm in diameter to p
lyudmila [28]

Answer:

10573375000

216.57162\ N/C

Explanation:

k = Coulomb constant = 8.99\times 10^{9}\ Nm^2/C^2

r = Distance = \dfrac{d}{2}=\dfrac{23}{2}=11.5\ cm

E = Electric field = 1150 N/C

Electric field is given by

E=\dfrac{kq}{r^2}\\\Rightarrow q=\dfrac{Er^2}{k}\\\Rightarrow q=\dfrac{1150\times 0.115^2}{8.99\times 10^9}\\\Rightarrow q=1.69174\times 10^{-9}\ C

Number of electrons is given by

n=\dfrac{1.69174\times 10^{-9}}{1.6\times 10^{-19}}\\\Rightarrow n=10573375000

Number of excess electrons is 10573375000

r = 0.115+0.15 = 0.265 m

E=\dfrac{kq}{r^2}\\\Rightarrow E=\dfrac{8.99\times 10^9\times 1.69174\times 10^{-9}}{0.265^2}\\\Rightarrow E=216.57162\ N/C

The electric field is 216.57162\ N/C

A body of mass 8 kg moves in a (counterclockwise) circular path of radius 10 meters, making one revolution every 10 seconds. You
Sav [38]

Answer:

Centripetal force is equal to 31.55 N

Explanation:

We have given mass of the body m = 8 kg

Radius of the circular path r = 10 m

It is given that it makes 1 revolution in 10 seconds

Distance traveled in 10 seconds is equal to d=2\pi r=2\times 3.14\times 10=62.8m

Velocity is equal to velocity=\frac{distance}{time}=\frac{62.8}{10}=6.28m/sec

We have to find the centripetal force

Centripetal force is equal to F=\frac{mv^2}{r}=\frac{8\times 6.28^2}{10}=31.55N

So centripetal force will be equal to 31.55 N
