90000m/3600s = 25 m/s

a=0-25/10 ⇒ a = - 5/2 m/s^2

What is a convex lens?

Leona [35]

The convex lens is a lens that converges rays of light that convey parallel to its principal axis (i.e. converges the incident rays towards the principal axis) which is relatively thick across the middle and thin at the lower and upper edges. The edges are curved outward rather than inward.

Which is greater the attraction of the earth for 1 kg of aluminum or aluminum or attraction of 1kg of aluminum for the earth?

OleMash [197]

Those forces are exactly equal.

Gravity always works as a pair of EQUAL forces ... one in each direction
between two masses. Your weight on the Earth is exactly the same as
the Earth's weight on you.

Initial velocity 10 m/s accelerates at 5 m/s for 2 seconds whats the final velocity

stiks02 [169]

Answer:

The final velocity is 20 m/s.

Explanation:

Constant Acceleration Motion

It's a type of motion in which the velocity of an object changes by an equal amount in every equal period of time.

Being a the constant acceleration, vo the initial speed, and t the time, the final speed can be calculated as follows:

$v_f=v_o+at$
