As per the question the, the initial velocity of object [u] =0

The acceleration of the block  [a]=2\ m/s^2

The time taken by the object[t] = 9 s.

We are asked to calculate the distance travelled by the object in that time.

As per equation of kinematics we know that-

                                 s=\ ut+\frac{1}{2} at^2

Here s is the distance travelled by the object.

                                       =0*9+\frac{1}{2} 2*[9]^2\ m

                                       =81\ m     [ans]

blondinia [14]

Answer:

Explanation:

The point at which magnetic field is to be found lies outside wire so while applying Ampere's law we shall take the whole of current . If B be magnetic field which is circular around conductor.

Applying Ampere's law :-

∫ B dl = μ₀ I      ; I is current passing through ampere's loop

B x 2π x 2.00 = 4 x π x 10⁻⁷ x 2

B = 2 x 10⁻⁷ T.

Which of the following objects would have the strongest gravitational pull on a third object positioned at an equal distance fro
3241004551 [841]
I believe Box B will have a greater gravitational pull because the gravitational pull of an object depends on its mass. The more mass an object has, the greater its gravitational pull will become.

For example, we can take planets. Naturally, they are round because once upon a time there was a larger piece of rock that attracted others. But the size of the rock won't matter, it's the weight that matters. If the rock weighed nothing, the other rocks would just rebound upon contact. But if the rock weighed a lot, then things wouldn't so easily rebound and might actually stick to it.
