Describe the results of Ernest Rutherford's gold-foil experiment and explain how his results changed ideas about the distributio

n of positive charge within the atom.

In Rutherford's gold foil experiment, some of the positive particles would pass through the foil and some would bounce off. This led to a new theory that all of the positive subatomic particles were in the center of the atom instead of evenly spread throughout.

4. As Juan is going to take a shower, the soap falls out of the soap dish on to the
LiRa [457]

The coefficient of friction between the soap and the floor is 0.081

If Juan steps on the soap with a force of 493 N, this is her weight, W. This weight also equals the normal reaction on the floor, N.

We know that frictional force F = μN where μ = coefficient of friction between soap and floor.

So, μ = F/N

Since F = 40 N and N = W = 493 N,

μ = F/N

μ = 40 N/493 N

μ = 0.081

So, the coefficient of friction between the soap and the floor is 0.081

Using carson's rule, what is the required bw to transmit an fm signal if the maximum deviation is 60 khz and intelligence freque
VashaNatasha [74]

Carson's Rule says:

FM occupied bandwidth =

(2) · (Peak deviation + Highest modulating frequency)

so

FM bw = (2) · (60 kHz + 15 kHz)

FM bw = (2) · (75 kHz)

FM bw = 150 kHz

A 1kg box is pushed on a flat surface that is 250m long. The box is initially at rest and then pushed with a constant Net force
sasho [114]

Answer:

C) 50 m/s

Explanation:

With the given information we can calculate the acceleration using the force and mass of the box.

Newton's 2nd Law: F = ma

  • 5 N = 1 kg * a
  • a = 5 m/s²

List out known variables:

  • v₀ = 0 m/s
  • a = 5 m/s²
  • v = ?
  • Δx = 250 m

Looking at the constant acceleration kinematic equations, we see that this one contains all four variables:

  • v² = v₀² + 2aΔx

Substitute known values into the equation and solve for v.

  • v² = (0)² + 2(5)(250)
  • v² = 2500
  • v = 50 m/s

The final velocity of the box is C) 50 m/s.

When a ball drops from the roof of a building, it speeds up as it falls. What energy transformation is happening?
finlep [7]

As initial position of the ball is upwards and at some height above the surface of Earth

so here we can say that initial total energy of the ball is in the form of gravitational potential energy

this is given by equation

U = mgh

here we know that

h = initial height of the ball from ground

now again we know that ball is released from rest from that initial height and it continue from this position

As it start falling down the speed of the ball will increase due to gravity so here we can say that as ball go down its kinetic energy will increase

so here correct answer for energy transform is

<em>A. Gravitational potential energy to kinetic energy</em>
