Answer:
p=mv=(813kg)(17)= 13,821 kg m\s
Answer:
c
Explanation:
When a satellite is orbiting the earth , a constant force is being applied on it which means it must has acceleration. Also the direction of satellite is always being changed when it is orbitting to there is always change in the velocity vector which means acceleration.
You can view in the attached diagram to understand how the velocity is being changed.
Answer:
Looks like A but I'm not sure.
Explanation:
dont take my word for it I might be wrong
The question doesn't describe any experiment. If the same experiment is repeated, no matter how many times, the acceleration due to gravity will remain the same as it was during the non-existent original experiment, and will have no effect on anything.
solution:
the spring force exerted by spring with spring constant k is given by
![F(x)=-kx](https://tex.z-dn.net/?f=F%28x%29%3D-kx)
where k is spring constant
and x is deformation of spring
in order to calculate word done by the spring
![W=\int\limits^L_0 {} \, dW](https://tex.z-dn.net/?f=W%3D%5Cint%5Climits%5EL_0%20%7B%7D%20%5C%2C%20dW)
the work done by the spring as it is compressed from x=0 to x=L
![W=-kx^2/2](https://tex.z-dn.net/?f=W%3D-kx%5E2%2F2)
inserting the limits x=0 and x=L
we get work done in terms of k and L
