Answer:
So, put simply, reflection is light bouncing off surfaces. The law of reflection determines how the light bounces off a surface. The law of reflection states that the angle of incidence is equal to the angle of reflection.

<span>Increased motion increases pressure. This is why warmer (more energy, moving faster) gases have more pressure than colder. They bump into each other more. Check your tire pressure now, then drive down the road a bit. Check again.

Explanation:
Answer:
negative charge
Explanation:
As the glass rod is rubbed with the cotton cloth, then the glass rod becomes positively charged and the cotton cloth becomes negatively charged.
There is a tendency to lose the electrons by the glass rod and to grab the electrons by the cotton cloth.
So, the sensor shows negative charge.
Answer: 0.102m/s^2
Explanation:
velocity of ball = 6.15 m/s
Time taken for ball to roll = 1.00 minute
Convert 1.00 minute to seconds
(Since 60 seconds = 1 minute, the time taken for ball to roll = 60 seconds
Acceleration of the ball = ? (Let unknown value be Z)
Since acceleration is the rate of change of velocity per unit time
i.e Acceleration = Velocity / Time
Z = (6.15 m/s / 60 seconds)
Z = 0.1025m/s^2
Round Z to 3 significant digits (Z = 0.102m/s^2)
Thus, the acceleration of the ball is 0.102 metres per second square
