Radiation because solar panels trap the suns energy which is known as radiation
Answer:
No
Explanation:
When the two bodies at different temperatures then heat transfer takes place between two bodies. Temperature is the necessary condition for the heat transfer.
The energy can flow due to pressure difference but the heat transfer can not take place only due to pressure difference. Heat transfer needs temperature difference.
Therefore the answer will be No.
The mass will accelerate. Balanced Forces: When forces are in balance, acceleration is zero<span>. </span>
Answer: Option (C)
Explanation: Rock cycle plays an important role in the alteration of rocks from one form to another.
- Igneous rocks when undergoes high temperature and pressure condition, it transforms into a metamorphic rock.
- Sedimentary rocks are formed from the sedimentation and consolidation of sediments
- Igneous rocks are formed due to the crystallization of magma.
Hence the correct answer is option (C)
Answer:
W = 650 [kJ]
Explanation:
The definition of work is denoted by the product of force by the distance traveled by the body, this distance traveled corresponds to the direction of the force.
In this case we have:
d = distance = 2.6[km] = 2600 [m]
F = force = 250 [N]
W = F*d = 250 * 2600 = 650000 [J] or 650 [kJ]
