Answer:
<em>The work done is 100,000 Joule</em>
Explanation:
<u>Work and Power
</u>
Work is the amount of energy transferred by a force.
If both the force F and displacement s are parallel, then we can use the formula:
W = F.s
Power is the amount of energy transferred or converted per unit of time. In the SI, the unit of power is the watt, equal to one joule per second.
The power can be calculated as:
Where W is the work and t is the time.
We know the power needed to move a spoon is P=10,000 Watt and it took a time of t=10 s. The work done on the spoon is calculated by solving for W:
W = Pt
W = 10,000 Watt * 10 sec
W = 100,000 Joule
The work done is 100,000 Joule
Answer:
and
Explanation:
Given:
- first charge,
- second charge,
- position of first charge,
- position of second charge,
Now since there are only 2 charges and of the same sign so they repel each other. This repulsion will be zero at some point on the line joining the charges.
<u>Now, according to the condition, electric field will be zero where the effects of field due to both the charges is equal.</u>
- since first charge is greater than the second charge so we may get a point to the right of the second charge and the distance between the two charges is 1 meter.
Since we have assumed that the we may get a point to the right of second charge so we calculate with respect to the origin.
and
(average mass of an apple) x (average number of apples in a bag) .
The answer is exact.
what?????????????!!!!!!!!!!!!!!
Newton's Third Law States that Every Action Has an Equal and Opposite Reaction. To stop or slow down an object, a force must be applied in the direction opposite to that of the object's motion. Exerting a force results in an equal force in the opposite direction (like the recoil a person feels when firing a gun)
