Answer:
I think it might be A
Explanation:
the reason I think this answer is because the intensity is 50%.
Answer:
The answer is letter B, absorb.
Explanation:
Heat travels through three different ways: radiation,conduction and convection.
Radiation- this happens when heat moves as energy waves (infrared waves) directly from its source to something.
Conduction- heat passes directly from one object to another through the touching of surfaces.
Convection- this occurs when warmer areas of a liquid or gas rise to cooler areas in the liquid or gas.
The transfer of heat in the situation above is an example of "thermal radiation." The campfire carries light energy through the fire. These consists of electromagnetic waves (most of these are infrared light). These waves (radiation) carry energy, which is then converted to heat once it hits another object that absorbs it. In the case above, once the hands absorbs the energy, it then warms up. This happened because the hands are placed <u><em>near the campfire.</em></u> Placing the hands near the campfire is important because air is a poor thermal conductor.
Thus, the answer above is letter B, absorb.
The distance traveled by pendulum, in one back-and-forth swing is 75.75 inches.
The period of pendulum can be calculated by

Where,
- period
- length = 12 inches
- gravitational acceleration = 
Put the values,

Now, the angular displacement of the pendulum can be calculated by,

Where,
- amplitude
- angle = 
- angular displacement =
= 2.866 m
Put the values and calculate for
,

Therefore, the distance traveled by pendulum, in one back-and-forth swing is 75.75 inches.

Answer: D!
It is the option with the greatest amplitude.
Answer: Bohr's model
Explanation:
The Bohr's model is also known as the solar system model which describe that an atoms are basically imagine in the form of solar system. The Bohr's model basically describe about the atoms that it consist of nucleus with the number of electron in an orbit by using the electrostatic attraction.
The Bohr's model are introduced for overcoming the drawback in the Rutherford model as he proposed an idea that at different energy levels the electron can revolve in certain orbits around nucleus.
