The answer would be -62 because 62 x 1 equals 62 so that would be the answer.
Answer:
7 m to the left of the line of fire.
213.55 m from the foot of the wall.
7.25 m above the ground.
Explanation:
Let's assume the height is the y-direction, the line of fire is in x-direction. Since there is no external force acting in z-direction, z-coordinate of the center of mass of he ball should be zero. In order to make z-coordinate zero other ball should fall symmetrically with respect to z-axis. So, z-coordinate of 19 kg ball = -7 m.
Hence, 7 m to the left of the line of fire.
The balls do not have any external force in x-direction. Thus, in x-direction, the center of mass should move with constant velocity. x-coordinate of center of mass at t = 1.5 s is:
Hence, 213.55 m from the foot of the wall.
Height fallen by the center of mass at t = 1.5 s.
Hence, y-coordinate of the center of mass is:
Hence, 7.25 m above the ground.
Answer:
1. To bring down the pressure of the refrigerant
2. To meet up with the load to be refrigerated (the amount of heat to be evacuated)
Explanation:
1. To bring down the pressure of the refrigerant
The high pressure of the refrigerant coming from the condenser require reduction to enable vaporization in the evaporator at the proper temperature
The throttling valve as a small aperture through which the refrigerant flows that lowers the pressure of the refrigerant to a point at which the refrigerant vaporize of which the refrigerant then passes into the evaporator in a partly as liquid and vapor at a low temperature and pressure
2. To meet up with the load to be refrigerated (the amount of heat to be evacuated)
The throttling valve allows more refrigerant to flow through it when there is an increased load at a higher temperature to be refrigerated
Similarly, in a condition of reduced refrigeration load, hence, a lesser amount of heat to be evacuated, the throttling valve restricts the amount of flow of the refrigerant through it.

specialist focus in one very specific thing, generalist focus and many things, they are like a jack of all trades
Answer:
t = 5.27 years
Explanation:
First of all, the formula for corrosion penetration rate is given as;
CPR = (KW)/(ρAt)
Where;
K = Constant dependent on exposed area A.
W - weight lost after time
t- time
ρ - density
A - exposed area
From the question;
W = 7.6kg or 7.6 x 10^(6) mg
CPR = 4 mm/yr
ρ = 4.5 g/cm³
Area = 800 cm²
K is a constant of 87.6cm
Making t the subject of the formula from the CPR equation, we obtain;
t = KW/(ρA(CPR))
t = (87.6 x 7.6 x 10^(6))/(4.5 x 800 x 4) = 46233.3 hours
The question wants the time in years.
So let's convert;
There are 8760 hours in a year.
Thus;
t = 46233.3/8760 = 5.27 years.
