Answer: 1. Reflection: light behavior in which light waves bounce off a medium and goes in a different direction.

Refraction: light behavior in which light goes through a medium and bends, going in a different direction.

Convex: a surface shaped in such a way that the center curves outward

Concave: a surface shaped in such a way that the center curves inward

Explanation: When light bounces on a surface instead of being absorbed, then it goes in a different direction and that is called reflection while in refraction the light bends at the junction of two mediums because of varying densities.

A concave surface is one that curves inwards at the center like the interior of a circle while a convex surface is one that curves outwards like the outer part of  a circle.

At a given instant in time, two cars are traveling at different velocities, one twice as large as the other. Based on this infor
Sati [7]

Answer: No, is not possible.

Explanation:

We have two cars traveling at different velocities, one with velocity v and other with velocity 2*v

We want to know of it is possible to say which of these two cars has the larger acceleration at this instant of time.

Acceleration is the rate of change of the velocity, for example, if acceleration = 0, the velocity does not change.

Notice that knowing only the velocity at a given instant of time, we do not have any way of knowing the acceleration of each car.

Such that acceleration is given by the second Newton's equation:

F = m*a

force equals mass times acceleration.

We do not know any of these quantities for the cars, so we can not say anything about the accelerations.

We also could know the average acceleration if we know the change in velocity over an interval of time, such that:

Av acceleration = (change in velocity)/(interval of time)

But here we do not have a change in velocity, so again, we can't say anything about the acceleration.

A rubber ball moving at a speed of 5 m/s hit a flat wall and returned to the thrower at 5 m/s. Which statement
Step2247 [10]

Answer:

d. Its magnitude and its direction both remained the same.

Explanation:

Momentum can be defined as the multiplication (product) of the mass possessed by an object and its velocity. Momentum is considered to be a vector quantity because it has both magnitude and direction.

Mathematically, momentum is given by the formula;

Momentum = mass * velocity

The law of conservation of momentum states that the total linear momentum of any closed system would always remain constant with respect to time.

This ultimately implies that, the law of conservation of momentum states that if objects exert forces only on each other, their total momentum is conserved.

In this scenario, a rubber ball moving at a speed of 5 m/s hit a flat wall and returned to the thrower at 5 m/s. Thus, the statement which correctly describes the momentum of the rubber ball is that its magnitude and its direction both remained the same because its velocity didn't change while returning to the thrower.

Define kinetic energy <br><br><br><br>have a great day ​
Strike441 [17]

Answer:

In physics, the kinetic energy of an object is the energy that it possesses due to its motion.It is defined as the work needed to accelerate a body of a given mass from rest to its Stated velocity. Having gained this energy during its acceleration, the body maintains the kinetic energy unless it's speed changes.

(or in short)"Energy which a body possesses by virtue of being in motion"
