Answer: Long Answer...
Explanation: Most of the time, chemical energy is released in the form of heat, and this transformation from chemical energy to heat, or thermal energy, is called an exothermic reaction. Next, there are two main types of mechanical energy: kinetic energy and potential energy.
Resistance can be calculated by Ohm's law
As per ohm's law we will have

here we will have
voltage = 220 volts
current = 10 A
So by the above formula we will have


So resistance of the bulb is 22 ohm.
Answer:
Has been removed 1.458 moles.
Explanation:
n1= 1.8 mol
p1= 27.3 atm
p2= 5.2 atm
n2= ?
n2= n1 * p2/p1
n2= 0.342 moles
Δn= n1-n2
Δn= 1.458 moles
Answer:
F=507.7N
Explanation:
According to Newton's second law:

in this case, the football players need to drag the coach at a constant velocity, thus means with no acceleration, so:

there are 20 degrees between the two ropes that means each player exerts a force 10 degrees from the zero reference.
