Light rays change direction when they hit a mirror. The phenomenon is known as reflection. Light rays travels in a straight light. They strike the surface of the mirror at a particular angle called incident angle. It is the angle between the ray and normal at the point of contact. The rays leaves the surface making the same angle with the normal called reflection angle but in different direction.

Answer:
The Kinetic energy of the Cheeto truck = 130,500 J
Explanation:
The Formula for Kinetic energy is
K.E = 1/2 x M x V^2
So in this Situation Mass(M) is 290kg
Velocity (V) is 30 m/s
Inputting these values into our equation gives us
K.E = 1/2 x 290 x 30^2
30 times 30 = 900
So K.E = 1/2 x 290 x 900
Simplifing this we get : K.E = 290 x 450
So K.E = 130,500 Kgm^2/s^2
Now the unit's Kgm^2/s^2 scientific name is Joule and symbol (J).
So K.E = 130,500 J
P.S: Oh man, now I have a craving for some Cheetos!
Answer:
Explanation:
The longer arm means the force needed to create the required torque is lower than for the short handled spanner.
