We know that t=2.8571428571428568
and therefore 28*2.8571428571428568 - 9.8*2.8571428571428568^2/2
is around 40 m
Answer:
The maximum temperature rise = 0.047 °C
Explanation:
Potential Energy, P = mgh
Energy transfered, Q=mcΔT
Potential energy = Energy transfered
mgh = mcΔT
gh = cΔT
ΔT = gh/c
ΔT = (9.81 * 20) / 4186
ΔT = 0.047 °C
Answer:
D
Explanation:
f = ma
2 x 12 = 24
answer could differ since it's rolling down a ramp. if an angle is given our approach differs.
Wave A would have higher amplitude
Hope this helps :D
Any photos so i can help you with that?
