Answer:

The low side pressure of an A/C system losing vacuum and the pressure rising above zero indicates that there is too much refrigerant in the system.

Explanation:

Considering an A/C system, the condenser fan might be malfunctioning if the low side pressure of the air conditioner is excessive. On the other hand, it's also conceivable that the system has been overcharged with refrigerant.

Stated the scenario that the refrigerant of the system was being recovered, it is an indication that the system is merely overcharged. Even with the engine off, you will notice high pressures.

Either too much oil is present, or there is too much refrigerant in the air conditioning system. In either case, until you let some of that pressure out—ideally, a mechanic should do this—the issue won't go away on its own.

What is a compound formed in protein metabolism and present in much living tissue?
Mamont248 [21]

Answer:

Creatine

It is the compound, formed in protein metabolism and present in much living tissue. It is involved in the supply of energy for muscular contraction.

Creatine improves the strength and increase the lean muscle mass to help the muscles recover more quickly during exercise.

Creatine helps muscle cells to produce more energy. In high intensity exercise, its primary role is to increase the phosphocreatine stores in the muscles.

Creatine is also nitrogenous organic acid that helps in supply of energy in the body. It occurs naturally in meat and fish. It is made by the body. It also obtained by the supplements.

A pendulum is hanging from a point and its total mechanical energy is 20,000 J. Neglecting friction, if energy is conserved, wha
AlexFokin [52]

(1) The pendulum will have maximum velocity at the lowest point and it will be the most difficult point to stop.

(2) Velocity at maximum height is zero and it will be the easiest point to stop the pendulum.

(3) The total mechanical energy of the pendulum would  be the same at all point.

<h3>Point of maximum velocity of the pendulum</h3>

A pendulum has maximum kinetic energy at the lowest point. The kinetic energy is given as;

K.E = ¹/₂mv²

The pendulum will have maximum velocity due to maximum kinetic energy at the lowest point and it will be the most difficult point to stop.

<h3>Point of maximum height of the pendulum</h3>

A pendulum has maximum potential energy at the highest point. The potential energy is given as;

P.E = mgh

Velocity at maximum height is zero and it will be the easiest point to stop the pendulum.

<h3>Conservation of energy</h3>

In absence of friction, the total mechanical energy will be conserved. Thus, the total mechanical energy of the pendulum would  be the same at all point.

Strike441 [17]

In order to predict whether a star will eventually fuse oxygen into a heavier element, you mainly want to know about the star's mass.

<u>Explanation:</u>

Stellar evolution is procedure by which star experiences a succession of radical change during its lifetime. Depending upon the mass of stars, this lifetimes range from just two or three million years for most big to the trillions of years for a least massive, which is significantly longer or more than the age of universe.

All stars are conceived from falling billows of gas and residue, frequently called nebulae or sub-atomic mists. Throughout a large number of years, the protostar settles down into a condition of balance, turning out to be what is also known as the main- sequence - star.
