Answer:
the angle of reflection also increases
Explanation:
this is because the law of reflection states that the angle of incidence equals to the angle of reflection, thus, if the angle of incidence increases, angle of reflection should also increase, basically , think as if the angle of incidence is the same thing as the angle of reflection

A person wants to redesign a large room in a house to have less echoing of sound and more sunlight. Which design solution will best match the persons needs?
(A.) Hang curtains over the windows that will transmit sound waves and absorb light waves.
(B.) add pillows to the furniture that will reflect sound waves and refract light waves.
(C.) Place a thick white carpet on the floor that will absorb sound waves and reflect light waves.
(D.) Add a large mirror on the wall that will refract sound waves and reflect light waves.
Answer:
(A.) Hang curtains over the windows that will transmit sound waves and absorb light waves
explain the basic concept that involves projectiles
How does the initial velocity of a projectile affect its range?
N - Projectiles with larger initial velocity will go farther
0 - Projectiles with larger initial velocities will not go as far
P-Initial velocity has no effect

Answer:
C. Van der Waals forces
Hydrogen bonds
Metallic bonds
Ionic bonds
Explanation:
This list orders the types of forces from weakest at the top to strongest at the bottom. Van der Waals forces are relatively weak intermolecular forces, followed by hydrogen bonds which are stronger. Metallic bonds are even stronger, and ionic bonds are the strongest among the listed forces.
Explain how neutrons enable a nuclear chain reaction to take place. (2)
Answer:
Explanation:
In addition to the 'daughter' products, two or three neutrons also explode out of the fission reaction and these can then collide with other uranium nuclei which are unstable so these cause further fission reactions. This is known as a chain reaction .

describe how an electromagnet can be switched on and off.
Answer:The magnetic field around an electromagnet is just the same as the one around a bar magnet. It can, however, be reversed by turning the battery around. Unlike bar magnets, which are permanent magnets, the magnetism of electromagnets can be turned on and off just by closing or opening the switch.

A car is coasting backwards downhill at a speed of 3.0 m/s when
the driver gets the engine started. After 2.5 sec, the car is
moving
uphill at 4.5 m/s. Assuming that uphill is the positive
direction, what is the car's average acceleration?
If a car is coasting backward downhill at a speed of 3. 0 meters / s when the driver gets the engine started. After 2.5 sec, the car is moving uphill at 4.5 meters / second . Assuming that uphill is the positive direction the average acceleration of the car would be 3.0 meters / second².
What is acceleration?The rate of change of the velocity with respect to time is known as the acceleration of the object. Generally, the unit of acceleration is considered as meter / seconds².
As given in the problem If a car is coasting backward downhill at a speed of 3. 0 meters / s when the driver gets the engine started. After 2.5 sec, the car is moving uphill at 4.5 meters / second .
The average acceleration of the car = + 4.5 - ( - 3 .0) / 2.5
= 3.0 meters / second ²
Thus , the average acceleration of the car would be 3.0 meters / second².
