A10- kilogram block is pushed across a horizontal surface with a horizontal force of 20 n against a friction force of 10 n. the acceleration of the block

Explanation:

Mass of block=10 kg

Applied horizontal force =F=20 N

Friction force=f=10 N

We have to find the acceleration of block.

Net force=Applied horizontal force-friction force

Where F= Horizontal force

f=Friction force

m=Mass of object

a=Acceleration of object

Hence, the acceleration of the block=

the working equation for the angular size is the product of the physical size and 360 degrees divided by the product of two pi and distance from earth. the minimum size would be 0.559 degrees while the maximum size would be 0.49 degrees.
