Answer:
The answer is 4200 J.
Explanation:
The formula of work done is, W = F×D where F is the force of an object and D is the distance. Then you just substitute the values into the equation :
W = F×D
F = 42N
D = 100m
W = 42 × 100
= 4200 J
It increases, because the centripetal acceleration is inversely proportional to the radius of the curvature.
Hopr it helps :)
Hi
The answer to this question is B. Reaction
(186,000 mi/sec) x (3,600 sec/hr) x (24 hr/da) x (365 da/yr)
= (186,000 x 3,600 x 24 x 365) mi/yr
= 5,865,696,000,000 miles per year (rounded to the nearest million miles)
Answer:
a
b
Explanation:
Generally the force of attraction between this two irons is mathematically represented as
Here k is known as the proportionality constant with value
substituting -2 for i.e the charge on oxygen , +1 for i.e the charge on Lithium and for r
So
Generally the force of repulsion will be the magnitude but different direction to the force o attraction
So Force of repulsionn is
