Veronica’s velocity was measured as 4.3 m/s. She displaced 20 meters in 4.7 seconds. Which piece of information is missing for the correct calculation of velocity? A) the starting point
B) the direction
C) the end point
D) the time per meter
Answers
The piece of information that is missing for the correct calculation of velocity is the direction.
What is velocity?
Velocity is the rate of change of distance. Velocity is a vector quantity. A vector quantity depends on magnitude and direction as well.
If forward direction, then velocity would be positive and if backward direction, it would be of negative.

Final answer:
Sound waves in air are a series of periodic condensations and rarefactions.
Explanation:
Sound waves in air are a series of periodic condensations and rarefactions. When a sound is produced, it creates compression regions (areas of high pressure) and rarefaction regions (areas of low pressure) that propagate through the air. These alternating regions of high and low pressure create the characteristic waveform of the sound wave.

Answer:
The percentage of its mechanical energy does the ball lose with each bounce is 23 %
Explanation:
Given data,
The tennis ball is released from the height, h = 4 m
After the third bounce it reaches height, h' = 183 cm
= 1.83 m
The total mechanical energy of the ball is equal to its maximum P.E
E = mgh
= 4 mg
At height h', the P.E becomes
E' = mgh'
= 1.83 mg
The percentage of change in energy the ball retains to its original energy,
ΔE % = 45 %
The ball retains only the 45% of its original energy after 3 bounces.
Therefore, the energy retains in each bounce is
∛ (0.45) = 0.77
The ball retains only the 77% of its original energy.
The energy lost to the floor is,
E = 100 - 77
= 23 %
Hence, the percentage of its mechanical energy does the ball lose with each bounce is 23 %

Answer: The correct answer is balanced force.
Explanation:
Balanced forces are balanced when the forces are acting equal in magnitude but opposite in direction. The balanced forces will not cause change in the speed of the object.
Unbalanced forces are unbalanced when the forces acting on the object are not equal in magnitude. The combined force is the difference between the forces. It will cause the change in the speed of the body.
Therefore, forces that are equal in size but opposite in direction are balanced.

(distance covered) / (time to cover the distance) .
The car's average SPEED is
(100 km) / (15min)
= 6-2/3 km per minute.
VELOCITY is
(distance and direction between start-point and end-point)
divided by
(time to travel from start-point to end-point).
The car ended up at the starting point, so the distance between
stating-point and end-point is zero.
Velocity = (zero) / (time to travel from start-point to end-point)
= Zero .
