Answer:
A)
B)
Explanation:
Given that
Force = F
Increase in Kinetic energy = 
we know that
Work done by all the forces =change in the kinetic energy
a)
Lets distance = d
We know work done by force F
W= F .d
F.d=ΔKE
b)
If the force become twice
F' = 2 F
F'.d=ΔKE'
2 F .d = ΔKE' ( F.d =Δ KE)
2ΔKE = ΔKE'
Therefore the final kinetic energy will become the twice if the force become twice.
Answer:
yeah meeeeee will add you
12 divided by 2/5 is 30.
The difference between 764.7 and 45.39 is 719.31.

Answer:
The amounts will stay the same.
Explanation:
We have a case here. O°C ice into O°C water in an insulated container. The poser here is that what would be the net effect.
It must be highlighted that the insulated container is parody of a constant room temperature and pressure. Meaning all factors are held constant.
Also, a O°C ice is simply the same as a O°C water. Hence, viewing the question under this context, and also acknowledging the constant environment, tells us that the two - Ice and Water at such temperature, will remain unchanged. The effect will be neural.
The underlying factor is that both substances are subjected to same conditions. Hence, the latent kinetic energy and other molecular movements that could occasion will be doing so at same level and frequency. Thus, producing a neutral or almost non different result.
Sound waves are mechanical waves so they need a medium for propagation.
Explanation:
The most fundamental properties of sound waves are:-
1. Wavelength
2. Frequency
3. Amplitude
