Answer: 13.46 m/s
Explanation:
Initial velocity V1 = 5.82 m/s
acceleration A = 2.35m/s^2
Time taken T = 3.25s
Final velocity V2 = ?
Recall that acceleration is the rate of change of velocity per unit time i.e acceleration = (V2 - V1)/T
2.35m/s^2 = (V2 - 5.82 m/s) / 3.25s
cross multiply
2.35m/s^2 x 3.25s = (V2 - 5.82 m/s)
7.6375m/s = V2 - 5.82 m/s
V2 = 7.6375m/s + 5.82m/s
V2 = 13.46 m/s
Thus, the car final velocity is 13.46 m/s
Answer:
The answer is 1020 meters.
Explanation:
The values given by the problem are:
1. T= The falling time of the rock [Seconds]
2. H=The sound velocity constant [meter/second]
The Velocity normal formula is
V=H/T
340=H/3
340*3=H
This solution considers the physic of the traveling wave sound but not really the rock falling problem, because the problem ask for the height of the cliff not even more.
<span>A spring balance will give a different mass reading on the Moon from that on Earth. A beam balance however, will give the same reading.Explain why.
</span>
<span>Beam Balance:
Beam balance measures mass.
Mass is the amount of matter the object has.
The S.I. unit of mass is kg
</span><span>
Spring Balance:
Spring balance measures weight not mass.
Disadvantage: It requires gravity to measure.
The S.I. unit of weight is newton (N).
That is why when we are in outer space, we become lighter-there is less gravity!</span>
Mass remains constant while weight is dependent on the gravitational pull of the planet. Mass only changes with a change in matter that results in a change of volume.
<span>Mass remains constant throughout. Only weight changes with gravitational acceleration. Mass will only change with a change in the volume of matter in the body.</span>
There is a push and pull exerted on the object while it is falling which is called gravity/force.
