Answer:
w=m×g= 40×9.8=?
Explanation:
solve this question your self
I give you formula
Answer:
As the "plates" on each side of ridges in the seafloor are pulled away, lava comes up from the middle, hardens and "records" the current magnetic field.
Explanation:
Normal force is mass x gravity, so mass x 9.81
Answer:
α = 2.6 +1.7 t - 0.14 t³
Explanation:
Given that
ω(t) = at + bt² - ct⁴
where a = 2.6 rad/s², b = 0.85 rad/s³ and c = 0.035 rad/s⁵
We know that angular acceleration is the rate of change of angular velocity
α = dω/dt
ω(t) = at + bt² - ct⁴
dω/dt= a + 2 b t - 4 ct³
So
α = a + 2 b t - 4 ct³
By putting the values of a b and c
α = a + 2 b t - 4 ct³
α = 2.6 + 2 x 0.85 t - 4 x 0.035 t³
α = 2.6 +1.7 t - 0.14 t³
Because the sun is not hitting the light on them and there not as bright like when we see them when it's dark.
