When two objects are near each other, how would increasing one object’s mass affect it? the shape of the object would change. the weight of the object would decrease. the gravitational force of the object would increase. the mass of the object would be stronger than gravity.

When two objects are near each other, increasing the mass will cause the gravitational force on the objects to increase.

According to Newton's law of universal gravitation, the force of attraction between two objects in the universe is directly proportional to the product of the objects masses and inversely proportional to the square of distance between the two objects.

where;

The force of attraction increases with increase in mass of the two objects. The force of attraction also increases when the distance between the two objects are small.

Thus, we can conclude that when two objects are near each other, increasing the mass will cause the gravitational force on the object to increase.

When two objects are near each other, increasing one object’s mass would cause the gravitational force of the object to increase.

The formula for gravitational force (F) is

where m and M are the masses of the two objects, d is the distance between their centres, and G is the gravitational constant.

If we hold M and d constant, we can write

, where

Thus, gravitational force is directly proportional to the mass of the object.

If you increase the mass of an object, you increase its gravitational force.

a mercury barometer is a device that uses the physical properties of mercury in a tube to measure barometric pressure. mercury barometers are used for : -

1. measurement of atmospheric pressure  

2. determining the altitude of a place

3. weather forecasting

4. calibration and checking of aneroid barometers

5. application in fluid mechanics

6. measurement of pressure in aircrafts

7. surface weather analysis

8. preparation of barographs

9. usage in physical sciences like physics, astronomy & chemistry

10. preparation of aircraft altimeters

characteristics of mercury barometer : -

1.used to define and measure atmospheric pressure.

2.on the average at sea level the column of mercury rises to a height of about 760 mm.

3.this quantity is equal to 1 atmosphere.

4.it is also known as standard atmospheric pressure.

5.a barometer in which the weight of a column of mercury in a glass tube with a sealed top is balanced against that of the atmosphere pressing on an exposed cistern of mercury at the base of the mercury column, the height of the column varying with atmospheric pressure.

that tool would be a compass
