<span>The heavier the body is, the stronger its gravitational pull. Example, the Milky Way Galaxy has a gravitational pull because of the heavenly bodies such as stars and planets are surrounding it. A strong force is exerted if the mass of another body is bigger than the other body.</span>

Explanation:

Gravitational force :

Gravitation force is an attractive force which act between two bodies.

This force acts between the objects with mass.

The gravitational force is the proportional to the product of their masses of the bodies and inversely proportional to the square of distance between the bodies.

Gravitational force only attraction force.

The gravitational force is very weak force.

Strong force :

The force which holds nucleus together it called strong force.

This force is attractive and repulsive force.

The strong force like electromagnetic force it has short range.

The range of strong force is 10⁻¹⁵ m.

The ________ method is duct sizing that considers the each duct section has the same air velocity.
Gennadij [26K]

The equal velocity approach for duct size assumes that the air velocity in each duct segment is the same.

How fast is the air moving through a duct?

The most common unit of air velocity (distance traveled in a unit of time) is feet per minute (FPM). The amount of air passing past a location in the duct per period of time may be calculated by multiplying the airflow by the area of the duct. The standard unit for volume flow is cubic feet per minute (CFM).

What happens when the size of ducts changes to the airflow?

  • Result for an image The equal velocity technique for duct size makes the assumption that air velocity is constant across the entire duct system.
  • The main lesson to be learned from this is that when air goes from a bigger to a narrower duct, its velocity rises. The velocity drops when it transitions from a shorter to a bigger duct. The flow rate or the amount of air passing through the duct in cubic feet per minute is the same in all scenarios.

Two identical blocks of iron are placed in contact, one at 10°C and the other at 20°C. If the cooler block cools to 5°C and the
Alenkinab [10]

Answer:

this is violation of II law of thermodynamics

Explanation:

As per 2nd law of thermodynamics we know that heat always flows from high temperature to low temperature

If heat flows from low temperature to high temperature then it is only possible when some external work is done on the system

So here it says that initially two blocks are at 10 degree C and 20 degree C

Now the cool object will become cooler and hot object becomes hotter

which shows that heat is flowing from low temperature to high temperature

So this is violation of II law of thermodynamics

g the newly launched satellite has a gyroscope inside of it. the gyroscope has a moment of inertia that is 1/10 of that of the r
Ivenika [448]

Answer:

L

Explanation:

For every action, there is an equal and opposite reaction.

As the moment of inertia if the gyroscope is 1/10 of that of the remainder of the satellite, the angular velocity of the satellite will be 1/10 that of the spun up gyroscope and in the opposite direction.

L = Iω
