Answer: When it comes to energy saving, energy management is the process of monitoring, controlling, and conserving energy in a building or organization. Typically this involves the following steps: Metering your energy consumption and collecting the data.
Explanation:
Answer:
40.53 kg
Explanation:
Juggles 's mass = Mj
Bangles 's mass = 70 kg
Potential Energy is the Energy that an object gets due to its height of location
<em>Potential Energy = mass * gravitational acceleration * height</em>
Juggeles' s Potential Energy = Bangles potential energy
Mj * g * 3.8 = 70 * g * 2.2
Mj = 40.53 kg
Answer:
B
Explanation:
quantization of energy is only seen in atoms
The potential energy of the object is going to be gravitational: PE=mgh. Assuming we're talking about the gravitational potential energy relative to the bottom of the cliff, the object's height is 30 m. g is 9.8 m/s^2. We don't know its mass. You could technically use the equation F=mg to find the mass, where F=40 and g=9.8, but that's unnecessary. You can just substitute F into PE=mgh to get PE=Fh. Substitute the given values to get PE=40*30=120 J.
