Answer:
b. active solar heating systems
Explanation:
A solar collector is a device that collects and/or concentrates solar radiation from the Sun. These devices are primarily used for active solar heating and allow for the heating of water for personal use.
They cause magnetic storms. A magnetic storm is a fleeting
disturbance of the Earth's magnetosphere. A magnetic storm is caused by a solar
wind shock wave associated with solar coronal mass ejections, coronal holes, or
solar flares. It typically strikes the Earth's magnetic field 24 to
36 hours after the event.
(60 * 546) / 110 = 297
297 hrs.
Answer:
At constant pressure
Explanation:
Enthalpy of a system may be defined as the system's internal energy in addition to the product of the volume and pressure of the system.
It can be regarded as the system's capacity of heat transfer and to do non- mechanical work.
The enthalpy of the system at constant pressure gives the amount of heat or energy that is either absorbed by the system or released by the system.
The answer is D using the work formula
W= F•d but if it was against gravity, it would be 0 if gravity is exerting the same amount, I would pick D using the formula, but I'm not so sure sorry
