The answer is the last choice, the particle nature of light. The compton effect showed that a charged electron scatters the photon results in decreased energy but increase in wavelength.

Answer:

the particle nature of light

Explanation:

As we know that by the formula of Compton Effect we have

\lambda' - \lambda = \frac{h}{mc}(1 - cos\theta)

here in this formula we will say that when light of some given wavelength \lambda incident on a particle then after deviating from the particle the light will change its direction by some angle \theta.

And the wavelength of the particle will also changed to some different value as \lambda'

so here as per particle theory we will use the theory of momentum conservation as per which light of given momentum when hit a particle then it will transfer it momentum to the particle and deviated by some lesser momentum.

Due to decrease in momentum the change in wavelength of light is given by above formula

so this verify the particle nature of light

Katie rolls a toy car off the end of a table. Which path will the car follow when it leaves the table? A. B. C. D.
Dimas [21]

Answer:

parabolic path

Explanation:

As the cart reaches the end of the table with a horizontally directed velocity (only horizontal component), the cart will follow a parabolic path given by the combined action of:

(1) kinematic equation for motion under constant velocity in the horizontal direction (linear expression in terms of time), and

(2) kinematic equation for motion under constant acceleration (that of gravity) in the vertical direction (quadratic expression in terms of time)

A 445-N force is used to hold up a Papa Johns sign in place. What is the mass of the sign?
nikitadnepr [17]

Answer:

The mass of the sign is 44.5 kg.

Explanation:

Given that,

Force acting on the sign, F = 445 N

We need to find the mass of the sign.

Net force acting on it is given by :

F = mg

Where g is the acceleration due to gravity

m=\dfrac{F}{g}\\\\m=\dfrac{445\ N}{10\ m/s^2}\\\\m=44.5\ kg

So, the mass of the sign is 44.5 kg.

In midair in the international space station a 1 kg chunk of putty moving at 1 m/s collides with and sticks to a 5 kg chunk of p
Delicious77 [7]
<span>We know that the momentum keeps constant in a inelastic collisions, so the product of mass and speed do not change:
   m1 * v1 + m2 * v2 = m * v
 1 * 1 + 5 * 0 = (1 + 5) * v
  1 = 6 * v
 v = 1/6 m/s
   So the final speed of the 6 kg chunk will travel at 0.167 m/s</span>

The two cars collide at right angles in the intersection of two icy roads. Car A has a mass of 1965 kg and car B has a mass of 1
Sunny_sXe [5.5K]

Answer:

U2 = 47.38m/s = initial velocity of B before impact

Explanation:

An example of the diagram is shown in the attached file because of missing angle of direction in the question

Mass A, B are mass of cars

A = 1965

B =1245

U1 = initial velocity of A = 52km/hr

U2 = initial velocity of B

V = common final velocity of two cars

BU2 = (A + B)*V sin ¤ ...eq1 y plane

AU1 = (A + B) *V cos ¤ ....equ 2plane

From equ 2

V = AU1/(A + B)*cos ¤

Substitute V into equation 1

We have

U2 = (AU1/B)tan ¤ where ¤ = angle of direction which is taken to be 30°

Substitute all parameters to get

U2 = (1965/1245)*52 * tan 30°

U2 = 47.38m/s
