UkoKoshka [18]

Answer:

Total change in energy = 31 KJ.

Explanation:

Mass m=25 kg

Height h = 1 m

Initial velocity = 0

Final velocity = 50 m/s

Energy at initial condition

$E_1=mgh+\dfrac{1}{2}mv^2$

$E_1=25\times 10\times 1+0$

$E_1=250\ J$

Energy at final condition

$E_2=0+\dfrac{1}{2}\times 25\times 50^2$

$E_2=31250\ J$

So the change in energy = 31250 -250 J

The total change in energy = 31000 J

What is tear test? What do we understand from this test? How?

Anvisha [2.4K]

Explanation:

The tear test determines the force required by a material to undergo complete failure when there is already a crack or tear present in it.

With this test we understand a material's resistance to failure when there is already a crack present.

The material which already has a crack is placed in a tensile testing or universal test machine. So, both sides of the material along the crack are pulled until material failure takes place.

3. Which of the following statements is false?

MrRa [10]

Answer: c.An accumulator is not used in a system with a receiver/dryer

Explanation:

In a refrigeration system, a condenser is used to transfer heat and this occurs from the refrigerant to the air or water.

Then, the refrigerant then condenses to liquid when the hear has been transferred.

We should note that the condenser is normally mounted in front of the radiator. The receiver/dryer is a storage tank for the liquid refrigerant from the condenser.

The statement that an accumulator is not used in a system with a receiver/dryer is not true. This is because, the accumulator gives protection to the compressor which helps to prevent the failure of the compressor.

Therefore, the answer is C.
