Explanation:
The molecules are continually colliding with each other and with the walls of the container. When a molecule collides with the wall, they exert small force on the wall The pressure exerted by the gas is due to the sum of all these collision forces.The more particles that hit the walls, the higher the pressure.
If a gas is heated up, its particles move around more quickly. They hit the walls of their container harder and more often. This increases the pressure. Sometimes the pressure gets so great that the container bursts.
This is why balloons and tyyres burst if you blow them up too much. It's also why deodorant spray cans carry warning signs to tell you not to leave them in the sunshine. If they get too hot they explode.
If the machine doesn't decrease the amount of work that you do, it might still improve the quality of the final result of your efforts
D = m / V
D = 272 / 4
D = 68 g/cm³
Answer:
The capacitance of the capacitor is 31.84 μF.
Explanation:
Given;
power rating of the bulb, P = 100 W
voltage rating of the bulb, Vr = 100 V
operating voltage of the bulb, V= 141.4 V
frequency of the AC = 50 Hz
P = IV = 100 W
V = 100 V
I =
Ic = 1 A
The voltage across the capacitor is given by;
Therefore, the capacitance of the capacitor is 31.84 μF.
Answer:
Joanna's position would be -100.
Explanation:
Joanna's position would be 100 feets west to her house. Her position is negative because Joanna walked west of her house. The position would have been positive if she had moved east of his house, that is, to the school.
