ANSWER: 3. Gravity
EXPLANATION: gravity is the force that pulls every thing towards earth
Answer:
The law which describes the behavior of gases in the Sun is Gay-Lussac's Law
Explanation:
The states that the extremely high pressure of the gases in the Sun produces extremely high temperature;
Therefore, the relationship between the pressure, 'P', of the gas and the temperature, 'T', of the gas is a direct relationship, which can be expressed mathematically as follows;
P ∝ T
The law which best describes the behavior of gases in the Sun is Gay-Lussac's Law, which states that the pressure of a given volume of gas varies directly as the absolute temperature of the gas, as follows;
P = K·T
∴ P/T = K (Constant)
Similarity : inverse square law for strength of force compared with distance.
Answer:
<em>Yes, work has been done on the mud.</em>
<em></em>
Explanation:
Work is done on a body, when a force is applied on the body to move it through a certain distance. In the case of the mud, the tire exerts a centripetal force on the mud. The centripetal force moves the mud along a path that follows the circle formed by the tire in one revolution of the tire. The total distance traveled is the circumference of the circle formed. <em>The work done on the mud is therefore the product of the centripetal force on the mud from the tire, and the circumference of the circle formed by the tire, usually expressed in radian.</em>
