Since the car is at rest, the force experienced by car will be normal face(exerted by surface to which car is in contact) and weight of the car.
As the car is at rest, net force on the car should be zero.
Answer:
Because the hot tea is hot from a microwave or coffee machine when iced tea is cold from ice in the tea.
Explanation:
Answer:
Both A and B
Explanation:
The interaction of magnetic fields and armature results into a rotational force of the armature hence turning motion. It's important to note that you will always need two magnetic fields in order to experience the force since one magnetic field is at the rotating armature and another at the casing. Considering the arguments of these two technicians, both of them are correct in their arguments.
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>
