Answer:

Explanation:

We can solve this problem using the principle of conservation of energy.

Starting point. For higher up the ramp

          Em₀ = U = m g h

where h is the height of the ramp h = 3.00 m

Final point. For low

          Em_{f} = K = ½ m v²

as there is no friction the mechanical energy is conserved

          Em₀ = Em_{f}

          m g h = ½ m v²

          v = √ (2g h)

let's calculate

         v = √(2 9.8 3.00)

         v = 7.668 m / s

The electric force between two charges A. increases with distance between the charges B. increases if either one of charges gets
beks73 [17]

Answer:

Option (A) , (b) and (d) are correct option

Explanation:

According to Coulomb's law electric force between two charges is given by

F=\frac{1}{4\pi \epsilon _0}\frac{q_1q_2}{r^2}

From the relation we can say that force is directly proportional to magnitude of charges and inversely proportional to distance between them '

So if we increase the distance then force will decrease

Increase if any of the charge get larger

If force is attractive then both the charge will be of different sign and is force is repulsive then both the charges of same sign

From above conclusion we can say that (a), (b) and (d) are correct option

The _____ inside the stratosphere blocks ultraviolet radiation. apex
podryga [215]
The ozone layer that is inside the stratosphere blocks UV radiation.

The ozone layer contains high concentrations of ozone relative to other parts of the atmosphere. This was discovered by Charles Fabry and Henri Buisson who are both French Physicists. 

The ozone in the earth's stratosphere is created through ultraviolet light striking a group of ordinary oxygen molecules containing two oxygen atoms, subsequently splitting them into individual oxygen atoms and finally these said atomic oxygen then combines with unbroken O2 to create ozone (O3).
