Answer:
Explanation:
As we know that bullet strike the block and fix in it
so here if bullet and box is taken as a system then there is no external force on it
so here the initial momentum of bullet and block must be equal to final momentum of bullet and block
so here we have
now we have
now from above equation we have
Answer:
A) .27 A
Explanation:
v = ir
i = v/r
equivalent r = 45 * 90 / (45+90) = 30 ohms ( for the two r in parallel)
i = 8v / 30 ohm = 267 mAmps
Answer:
d = 0 [m].
Explanation:
Displacement is understood as the length and direction that a body travels to move from an initial point to an endpoint.
This displacement is represented with a vector or straight line that indicates the distance of the displacement and its length.
This displacement in an easier way to understand. It is the distance between the start point and the end point of the journey. Since the second point is equal to the first point, since Mary returns to the same place, there is no difference between the displacement.
Therefore the displacement is zero.
The correct answer is a, lunar eclipse
24. 02 N force of friction acting on the box.
<h3 /><h3>What is force?</h3>
A force is an effect that can alter an object's motion according to physics. An object with mass can change its velocity, or accelerate, as a result of a force. An obvious way to describe force is as a push or a pull. A force is a vector quantity since it has both magnitude and direction.
Force = mass. acceleration
Force = (2.2).(3.2)
Force = 7.04 N
Total force applied is 31.06 N
Frictional force = 31.06 - 7.04
Frictional force = 24. 02 N
24. 02 N force of friction acting on the box.
