Answer:
The answer to your question is: letter D
Explanation:
Fussion: means combine 2 light nucleus to form heavier nucleus.
Fission: means splitting heavy nucleus to form lighter nucleus.
In the figure we can see two light nucleus that combine to form heavier nucleus, so the answer is nuclear fussion.
The subway train is moving to the left and then comes to a stop, what direction is the acceleration will be towards right and will be positive.
The train comes to a stop, this means that the velocity gradually decreases. Hence, the acceleration must be positive and points towards the right.
velocity and acceleration:
velocity is the charge of alternate inside the position of an object, at the same time as acceleration is the rate of trade of the fee. consider the movement alongside a line. If the velocity and acceleration are in the same route, then the charge constantly will growth in time. inside the meantime, if the speed and acceleration are in contrary instructions, then the rate steadily decreases to 0 speed, reverses route, and now the velocity is in the identical path of the acceleration.

Answer:
Explanation:
The weight of the wheelbarrow will act downwards . Its component parallel to the plank will act downwards along the plank .
The value of component = mgsinθ
21.6 x 9.8 x sin20
= 72.4 N
The person shall have to apply force equal to this component so that the barrow moves with uniform velocity.
Force required = 72.4 N .
