Work is obtained by multiplying the force and the object's displacement. The force and displacement and force should be in the same direction in order to have work.
W = F x d
d = W / F
Substituting the known values,
d = 352 J / 45 N = 7.82 m
Thus, the displacement of the student is 7.82 m.
Answer:
v=0.04m/s
Explanation:
To solve this problem we have to take into account the expression

where v and r are the magnitudes of the velocity and position vectors.
By calculating the magnitude of r and replacing w=0.02rad/s in the formula we have that

the maximum relative velocity is 0.04m/s
hope this helps!!
Answer:
B). to the right
Explanation:
Since the direction of magnetic field is into the page
So here we know that

now the velocity is from bottom to top
so we have

now the force on the moving charge is given as

now we have


so force will be towards Right
Answer:
All of the above is the correct answer!!!
Explanation:
mark me brainliest
The element chlorine has 17 electrons, 17 protons and 18 neutrons....<span> In an atom there is an equal number of electrons and protons. The number of neutrons is found by subtracting the atomic number from the mass number ...
