Acceleration = speed/ time
a = Δv/Δ t
as Δv = v₂ - v₁ / t
a = 50m /s - 0 m/s / 60m
= 50m/s / 60m
= 0.834s⁻¹
We know, I = F.Δt
As Δt is increased to 4 times, then, F would decrease to 4 times, in order to keep that impulse constant.
In short, Your force will change to 1/4th of it's initial value
Hope this helps!
Answer:
ig d. transmits only green light.....
Answer:
the thermal energy transferred is 183,226.68 J
Explanation:
Given;
mass of iron skillet, m = 5.1 kg
initial temperature, t₁ = 295 K
final temperature, t₂ = 373 K
The thermal energy transferred is calculated as;
Q = mcΔt
where;
Δt is change in temperature, = t₂ - t₁
c is specific heat capacity of iron = 460.6 J/kg.K
Q = 5.1 x 460.6 x (373 - 295)
Q = 183,226.68 J
Therefore, the thermal energy transferred is 183,226.68 J
Well, the answer is obviously D, because it's the only one that starts with 3.134.
Moving the decimal place 9 times to the right will give us:
3,134,000,000
