Answer:
0.1 nm
Explanation
Potential deference of the electron is given as V =150 V
Mass of electron 
Let the velocity of electron = v
Charge on the electron 
plank's constant h =
According to energy conservation 
Now we know that De Broglie wavelength 
Answer:
So the bouy does not float with its axis vertical
Explanation:
From the question we are told that:
Diameter 
Length 
Weight 
Specific weight of sea water 
Generally the equation for weight of cylinder is mathematically given by
Weight of cylinder = buoyancy Force
Where
Therefore
Therefore
Center of Bouyance B
Center of Gravity
Generally the equation for\BM is mathematically given by
Therefore
Therefore
Therefore
So the bouy does not float with its axis vertical
Heat can be diverted away from the area you want to cool using the refrigeration cycle, also known as a heat pump cycle. This is done by repeatedly compressing and expanding the working refrigerant (air, water, synthetic refrigerants, etc.) to change its pressure.
<h3>What is the cycle of a heat pump?</h3>
- In order to heat the air within a building, a heat pump warms the air outside by drawing heat from it and adding it to it. The following procedure is used to achieve this: A gas is created when liquid refrigerant absorbs heat from the ambient air in the "evaporator."
- The pressure buildup from the compressor raises the temperature of the refrigerant, just like it does with everything that is put under pressure. The refrigerant is a heated vapor, ranging in temperature from 120° to 140°F, when it exits the compressor.
- The chemical refrigerant, once transformed from a gas to a liquid state, has a remarkable capacity to absorb heat. The heat inside your house might be absorbed and released outside when the refrigerant undergoes a state shift as a result of compression and pressurization.

Answer:
a) 8660 and 8640 alloys
b) 8660 alloy
Explanation:
Diameter of a cylindrical piece of steel = 75 mm ( 3 in )
Equivalent distance from quenched end for the center position is about 17 mm
a) If the quenching medium is moderately agitated water the alloys that will qualify are : 8660 and 8640 alloys because these are the two alloys that would have a minimum of 40 HRC at the center and also throughout the cylinder
b) if the quenching medium is a moderately agitated oil the alloy that will qualify is : 8660 alloy . because it is the only alloy that will maintain a minimum of 40 HRC at the center and also throughout the entire cylinder.
