Answer:
Explanation:
Given that:
The air resistance and friction = 700 N
The gravity caused force = 716 × 9.8 = 7016.8
Total force = (7016.8 + 700) N
Total force = 7716.8 N
∴
Answer:
Time according to earth clock (T0) = 0.22 years (Approx)
Explanation:
Given:
Time taken by light = 4.5 years
Time taken by ship = 5 years
Speed of light = c
Speed of ship (v) = 90% of c = 0.9c
Find:
Time according to earth clock (T0) = ?
Computation:
Time dilation is ,
Time according to earth clock (T0) = 0.22 years (Approx)
Answer:
- a.
- b.
Explanation:
<h3>a.</h3>The equation for the voltage V of discharging capacitor in an RC circuit at time t is:
where is the initial voltage, and
is the time constant.
For our problem, we know
and
So
This gives us
and this is the time constant.
<h3>b.</h3>At t = 18.8 s we got:
