The weight changes but the mass will stay the same.
Inertia is a force which brings all objects to a rest position. Fast-moving objects have more inertia than slow-moving objects. False - The speed of an object has no impact upon the amount of inertia that it has. Mostly True - Two objects of the same mass can weigh differently if they are located in different locations.
I don't know if this will help
Answer:
Length = 19 feet
Width = 14 feet
Explanation:
The perimeter, P, of a rectangle is given by

where l is the length and w is the width.
From the question, the length is 9 feet less than twice the width.

Substitute this in the equation for the perimeter.






Substitute for this in the equation for l.

Hence, the length is 19 feet and the width is 14 feet.
Answer:
The lights bounces from the object behind which hit one's eyes. The glass is transparent because it does not absorb any radiation
The correct answer to the question is : 19.6 N.
EXPLANATION :
As per the question, the mass of the object m = 2.0 Kg.
The object is falling near the earth's surface.
We are asked to calculate the gravitational force.
The gravitational force exerted by earth on the object is equal to the weight of the body. It is so because the weight of the body is the force with which any body on the surface of earth is attracted towards the centre of earth.
The weight of the body is calculated as-
Weight W = mg
Here, g is known as the acceleration due to gravity and g = 
Hence, weight of the body W = 2 × 9.8 N.
= 19.6 N.
Hence, the gravitational force on the object is 19.6 N.
