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
Answer:
The Gravitational Force between the 2 masses is approximately 1.209x10^32 Newton’s
Explanation:
Answer:
As velocity is uniform then acceleration will be zero.
Explanation:
They all stay the same regardless
Assuming that you mean to ask <em>. . . "What is 7.4 </em><u><em>as a fraction</em></u><em> in simplest form</em>?"
7.4 = 7 and 4/10
4/10 can be reduced to 2/5
7 represents = (7*5)/5 = 35/5
so . . 7 + 4/10 = 35/5 + 2/5 = 37/5 (improper fraction in simplest form)
or
. . . . 7 + 4/10 = 7 2/5 (mixed fraction in simplest form)
