I think it’s D-decreases the amount of work.
We are given with conditions on temperature, pressure and volume of gas. In this problem, we apply ideal gas law PV = nRT to solve what are asked.
1. PV = nRT ; n = m/MM
16.5 x10^6 Pa * 0.003785 m3= n * 8.314 Pa m^3/ mol K * (23+273) K
n = 25.38 mol; mass = 812.08 grams.
2. V at STP is 22.4 L/mol
3. PV = nRT = 1.5 atm * 0.003785 *1000 L = <span>25.38 mol * 0.0821 L atm/mol K * T ; T = 2.72 K
4. P * 55 m3/1000 = 25.38 mol * </span><span>8.314 Pa m^3/ mol K</span><span> * (24+273) K
P = 1139. 45 kPa</span>
Answer:
distance fallen = 122.5 m
speed = 49 m/s
Explanation:
Δd = vi*t - 0.5at^2
Δd = 0 - 0.5(9.8)(5^2)
Δd = -122.5 (i.e. 122.5m down)
a = (vf - vi) / t
9.8 = (vf - 0) / 5
vf = 49
Answer:
Hello There!
It is Speed.
Because in the question it is said that at which speed car is travelling.
Speed is a scalar quantity.
If it is velocity then first know this that it is a vector quantity.
It must include both magnitude and direction.
If it is velocity then it would be 40 mph east or west or north or south.

Answer:
The amount of potential energy stored in the magnetic field depends on both the strength of the magnet and the distance that another magnet or magnetic object is from it. ...
Explanation:
All objects have a gravitational force, no matter how small, but only some objects such as iron objects can have a magnetic force.
