a 20N mass is supported by two ropes. what is the tension in each rope? how woould i work this problem if i know the two angles and thats the only info i know.

Answers

Answer 1

Answer:
Before we could discuss this in any specific detail, I think we would have to
know the angles. A generic discussion without actual numbers for the angles
would be just plain too confusing.

The general approach is that the vertical components of both tensions
add up to 20N, and the horizontal components are equal but in opposite
directions. That's the only way that the mass is hanging motionless.

You have to find the horizontal and vertical components of the tensions
by using the angles and maybe the lengths of the ropes.

At a temperature of 280k, the gas in a cylinder has a volume of 20.0 liters.If the volume of the gas is decreased to 10.0 liters, what must the temperature be for the gas to remain at a constant pressure?

Answers

Answer:

T = 140 K

Explanation:

As we know by ideal gas law

$PV = nRT$

now if pressure of the gas is constant

then we will have

$V = (nR)/(P) T$

now we have

$V_1 = 20.0 litre$

$T_1 = 280 K$

$V_2 = 10.0 litre$

now from above equation

$(20.0)/(10.0) = (280)/(T)$

$T = 140 K$

Temperature should be 140k to maintain constant pressure

Calculate how long it takes for a stone falling from a bridge with an average acceleration downward of 9.8m/s^2 to hit the water. The stone starts from rest and hits the water with a velocity of 12.3m/s.

Answers

If the stone begins from rest and ends with a downward speed
of 12.3 m/s, then it must have spent

(12.3) / (9.8) = 1.26 seconds
