Answer:
W = 46 J
Explanation:
We need to find the angle between the two vectors Force vector and displacement vector.
First we will find the angle α of the force vector

Then we find the angle β of the displacement vector

With these two angles we can find the angle between the two vectors
∅ = α + β = 25.56 deg
The definition of work is given by the expression

The absolute value of F will be:

The absolute value of d will be:

Now we have:

It would be option C. It rotates, or spins, on its axis, but it revolves around the sun.
Answer:A brick is released with no initial speed from the roof of a building and strikes the ground in 2.50 s, encountering no ..
11.54 minutes
Explanation:
The decay rate equation is given by

where
is the half-life. We can rewrite this as

Taking the natural logarithm of both sides, we get

Solving for
,
