C. A shared public ledger on which entire bitcoin network relies
To solve this, we
use the formula:
y = v0 t + 0.5 a t^2
where y is distance, v0 is initial velocity, t is time
and a is acceleration
Since we know that total time is 8.5 seconds, hence going
up must be 4.25 s and going down is 4.25 s.
a = 0.379 g = 0.379 (9.8 m/s^2) = 3.7142 m/s^2
going up:
y = v0 (4.25) - 0.5 (3.7142) (4.25)^2
y = 4.25 v0 – 33.5439 -->
eqtn 1
going down:
y = 0 (4.25) + 0.5 (3.7142) (4.25)^2
y = 33.5439
y = 33.5439 m
Calculating for v0 from equation 1:
33.5439 = 4.25 v0 – 33.5439
4.25 v0 = 67.0877
v0 = 15.78535 m/s
answers:
a. y = 33.5439 m
b. v0 = 15.78535 m/s
c.
Answer
given,
Area = 0.7 m²
electric field of wave = 0.0400 V/m
time = t =30 s
intensity of electromagnetic wave
c is speed of light
I = 4.24 x 10⁻⁶ W/m²
the amount of energy required
E = I A t
E = 4.24 x 10⁻⁶ x 0.7 x 30
E = 8.9 x 10⁻⁵ J
