1. a=(v-v0)/t
a=14 m/s / 2s
a=7 m/s^2
2. <span>a=(v-v0)/t
</span>a=(30 m/s - 0 m/s) / 12 s
a=2.5 m/s^2
3. <span>a=(v-v0)/t
a=(37 m/s - 22 m/s) / 2 s
a= 7.5 m/s^2
4. </span><span>a=(v-v0)/t
a=(12 km/s - 0 km/s)/8 s

Answer:

Explanation:
From the question we are told that:
Time 
Generally the Period is given as

Therefore difference in frequency dF



Answer:
5.95 ml
Explanation:
Given info
P1=2.9 atm
V1=8.21 ml
P2=4 atm
From Boyle's law we know that p1v1=p2v2 where p and v are pressure and volume respectively. This is at a constant temperature. Making v2 the subject of formula then
V2=p1v1/p2
V2= 2.9*8.21/4=5.95 ml
Answer:

Explanation:
The velocity of the swimmer just before touching the water is:


The average force exerted on the diver by the water is determined by the use of the Principle of Energy Conservation and the Work-Energy Theorem:
