The magnitude is doubled. The direction doesn't change.
Answer:
1250 J
Explanation:
Work is said to be done when a force causes an object to move over a distance. The amount of work done (W) is calculated by multiplying the force by the distance traveled.
That is;
W = F × d
Where;
W = work done (J or N/m)
F = force (N)
d = distance (m)
Based on the information provided in this question, F = 5000N, d = 0.25m
Hence;
W = F × d
W = 5000 × 0.25
W = 1250J
Therefore, 1250Joules of work is done by the jack.
The strong nuclear force overcomes the electric force of repulsion thatacts among the protons in thenucleus. B. The weak nuclear force is involved in certain types of radioactive processes. A.The strong nuclear force is a powerful force of attraction that acts only on theneutrons and protons in the nucleus.
Explanation:
The difference in frequency can be calculated using the formula
f= source frequency from the ship
v'= speed of the wave reflected from the whale = 4.95 m/s
v= speed of the ship.
since, the source frequency and speed of the ship data is missing, calculation of difference in frequency not possible.
Answer:
Two Neutral
Explanation:
If; One postive, and one negative they would be attracked. >-<
If; one postive and the other was postive, (or vice versa) they would repel <->
they both have an electrical charge, and force.
Neutral's are Nueatral. they have to opisition or attraction= No electrical force.
