Answer:
time required is 6.72 years
Explanation:
Given data
mass m = 3.20 ✕ 10^7 kg
height h = 2.00 km = 2 × 10^3 m
power p = 2.96 kW =2.96 × 10^3 J/s
to find out
time period
solution
we know work is mass × gravity force × height
and power is work / time
so we say that power = mass gravity force × height / time
now put all value and find time period
power = mass × gravity force × height / time
2.96 × 10^3 = 3.20 ✕ 10^7 × 9.81× 2 × 10^3 / time
time = 62.784 × 10^10 / 2.96 × 10^3
time = 21.21081081 × 10^7 sec
time = 58.91891892 × 10^3 hours
time = 6.72 years
so time required is 6.72 years

Explanation:
I can only help you with question 7
B is the right answer.
A is wrong because when the angle is critical angle the light leaves medium 1 parallel to the surface.
C is wrong because light reflects only when travelling from a denser to a rarer/less dense medium.speed of light is lower in denser medium.
D is wrong because the frequency of the light doesn't change when travelling from one medium to another.
Answer:
<h2>142 J</h2>
Explanation:
The kinetic energy of an object can be found by using the formula
m is the mass
v is the velocity
From the question we have
We have the final answer as
<h3>142 J</h3>
Hope this helps you
Nucleus? that's what I'm guessing but I'm not sure it's right :/
