Explanation:
The direction of electric field is always tangential to field lines. However, free charged particles do not necessarily move alone the field lines. Curved field lines means that there is a continuous change of force on the charge and thus, its direction of acceleration would change accordingly. Moreover, if the charge is negative it is bound to move opposite to the field direction. Hence, we can say that although electric field is tangent to electric field lines, free charged particles do not necessarily move alone the field lines.
Answer:
They are equal
Explanation:
Newton 3rd Law of motion states that for every force applied or action there is usually an equal and opposite force.
Impulse = Force * time
It is measured in Newton seconds.
The force and time of collision is the same which translates to an equal impulse by both scenarios.
The power output in horsepower to raise the object is 13.14 horsepower(Hp).
<u>Explanation:</u>
It is known that power required to perform a work is defined as the ratio of energy utilized to do that work per unit time. So, we can write power as the ratio energy utilized to time taken for completing that work.
Thus,
As we known that energy utilized to complete a work will be equal to the work done on the object. Thus,
So,
As it is given in the question that mass of the object is 2000 kg and the object is displaced to 5 m from the ground. So the displacement will be 5 m and the weight of the object can be determined by multiplying the mass with acceleration due to gravity.
Thus, the power formulation can be written as
But, we need to find in horsepower unit. So, the conversion between watt and horsepower unit is
1 horsepower (hp) = 745.7 watts
Thus,
So, the power output in horsepower unit is 13.14 horsepower (Hp).
True > the more mass increases more friction
