D.2.0 s
Answer:
Explanation:
According to the conservation of momentum, if she throws the camera in the opposite direction of space shuttle, she drifts towards the shuttle.
The correct option is A.
J.J Thompson proposed the plum model of atomic structure. The model states that the atom is a sphere of positively charged matter in which electrons are embedded.
Rutherford designed an experiment to verify the truth of this model. He set up a beam of alpha particles which are to be passed a thin gold foil. If the JJ model of atomic structure is correct, all of the alpha particles suppose to pass through the foil, but some of the alpha particles bounced back while those that passed through the foil emerged at different angles.

(a) The magnitude of the force that the magnetic field exerts on the loop is 0.042 N.
(b) The direction of the force that the magnetic field exerts on the loop will be out of the plane.
<h3>
Magnetic force exerted on the loop</h3>
F = BIL
where;
- I is current in the loop
- L is length of the loop
emf = BVb
where;
- b is breadth of the loop
- V is velocity
- B is magnetic field
emf = 2.6 x 3 x 0.018 = 0.1404 V
Current in the loop, I = emf/R = 0.1404/0.8 = 0.18 A
<h3>Magnetic force</h3>
F = BIL
where;
F = 2.6 x 0.18 x 0.09 = 0.042 N
<h3>Direction of the force</h3>
The direction of the force that the magnetic field exerts on the loop will be out of the plane.
