i would choose a for 945 and a for faster
Answer:
Its the biggest terrestrial planet as the result of the interior being not able to cool down that much.
its rotates rapidly
Explanation:
the earth planet is not close to the sun,which puts it in the advantage of not loosing water.
When you look at this, you might not be sure which way to divide ...
Should you divide 6 by 5 or 5 by 6 ?
Here's a case where you can use your units to decide.
The question wants to know the 'period'. That's a length of time,
so the answer needs to have units of time.
If you divide 'cycles' be 'time', you'll get 'cycles/second'.
That's Hz. It's frequency, not time.
If you divide 'time' by 'cycles', you'll get 'seconds/cycle'.
That's time, and it's exactly the definition of 'period'.
Period = (6 seconds) / (5 cycles)
= (6 / 5) seconds/cycle
= 1.2 seconds
Answer: work done = 64,000J or 64KJ.
Explanation:
Work is said to be done if a force applied makes the object to move through a distance in the direction of the applied force. Work is the product of force and perpendicular distance in the direction of the applied force. It is represented by W, measured in Joules(J) and a scalar quantity.
Thus, work done(J)= force(N) × distance(m)
From the the question,
applied force= 1600N
distance=40m
Therefore, work= 1600 × 40
W= 64,000J
But, 1 kilojoules = 1000J
Therefore, 64,000J = 64,000 ÷ 1000
= 64KJ
Work done is 64KJ
