Anna studies the color of her bedroom wall using different lights. In sunlight, she sees that the wall is white.

Then she gets an idea for an experiment. Anna darkens the room and shines a beam of light that includes all the wavelengths of visible light onto the wall.

In this light, the wall appears <em>white</em>.  (Choiced)

Answer:

white

Explanation:

Anna will see aw white light on the wall. This is possible for a simple reason: Light, as we see it is a mixture of lights of different wavelengths. The different wavelengths mix and merge to give light that appears to be monochromatic - meaning of one wavelength. This single wavelength light is also of a single color. Inadvertently, the light will appear to be white.

Question 11 (1 point)

Answer:

gravitational potential energy.

Explanation:

Gravitational potential energy (GPE) can be defined as an energy possessed by an object or body due to its position above the earth surface.

Mathematically, gravitational potential energy is given by the formula;

G.P.E = mgh

Where,

G.P.E represents gravitational potential energy measured in Joules.

m represents the mass of an object.

g represents acceleration due to gravity measured in meters per seconds square.

h represents the height measured in meters.

This ultimately implies that, anytime there is height, the object must have gravitational potential energy.

Hence, an object possesses gravitational potential energy due to its height (position) and the earth's gravitational force.

A student throws a 120 g snowball at 7.5 m/s at the side of the schoolhouse, where it hits and sticks. What is the magnitude of
mr Goodwill [35]

Answer:

The magnitude of the average force on the wall during the collision is 6 N.

Explanation:

Given;

mass of snowball, m = 120 g = 0.12 kg

velocity of the snowball, v = 7.5 m/s

duration of the collision between the snowball and the wall, t = 0.15 s

Magnitude of the average force can be calculated by applying Newton's second law of motion;

F = ma

where;

a is acceleration = v / t

a = 7.5 / 0.15

a = 50 m/s²

F = ma

F = 0.12 x 50

F = 6 N

Therefore, the magnitude of the average force on the wall during the collision is 6 N.
