Explanation: I just took this quiz
When the ball on a spring is replaced by a smaller ball with half the mass : The period decrease by 29%
<h3>Calculate the Period </h3>
We will apply the formula below to calculate period
T = 
where :
T₁ / T₂ = 
where m₂ = m₁ / 2
Therefore :
T₂ = 
= 0.71 T
Hence we can conclude that the period will decrease by 29% ( i.e 100 - 71 ).

The Doppler effect is the term that best describes the change in frequency of waves when there is motion between the source of the waves and the observer. The correct option among all the options that are given in the question is the first option or option "a". I hope the answer helps you.
Answer:
4.617 s
Explanation:
The speed of 60 mi/h can be converted to m/s:
(60 mi/h) × (1609.344 m/mi) × (1 h)/(3600 s) = 26.8244 m/s
The relationship between speed and acceleration is ...
v = at
t = v/a = (26.8244 m/s)/(5.81 m/s²) ≈ 4.617 s
It will take the car 4.617 seconds to reach 60 mi/h starting from rest.
Answer: 60.0 kg*m/s north.
Explanation: The linear momentum is a verctor, it has magnitude and direction. Also the momentun is proportional to the mass multiplier the velocity.
P=m*V ( vector)
