<span>So we want to know how many satellites exist in Earth's orbit today. If by satellites we mean artificial vehicles made to orbit the Earth, then, according to Goddard Space Flight Center's list, there is 2271 satellite in the Earths orbit today. So the correct answer is 2271. </span>
Seriously? It’s that hard to use a calculator??
B)H+ and e- i hope this helps you<span />
Answer:
Part a)
the tension force is equal to the weight of the crate
Part b)
tension force is more than the weight of the crate while accelerating upwards
tension force is less than the weight of crate if it is accelerating downwards
Explanation:
Part a)
When large crate is suspended at rest or moving with uniform speed then it is given as
here since speed is constant or it is at rest
so we will have
so the tension force is equal to the weight of the crate
Part b)
Now let say the crate is accelerating upwards
now we can say
so tension force is more than the weight of the crate
Now if the crate is accelerating downwards
so tension force is less than the weight of crate if it is accelerating downwards
