Answer:
Instantaneous velocity
Explanation:
Acceleration = rate of change of velocity
Average velocity = total displacement divided by total time taken
Position = It shows the location of the object
Instantaneous velocity = It is the velocity of an object at a particular instant.
The term that describes how fast and in what direction an object is moving at a particular moment is "instantaneous velocity". It is basically equal to the derivative of position wrt time.
Answer:
F = 100 N
Explanation:
The torque is given by the expression
τ = F x r
where bold letters indicate vectors, the magnitude of this expression is
τ = F r sin θ
In general, when tightening a nut, the force is applied perpendicular to the arm, therefore θ = 90 and sin 90 = 1
τ = F r
F = τ / r
calculate
F = 30 / 0.30
F = 100 N
