Answer: When there is an increased number of sun spots, it means the surface temperature is decreased which will decrease the temperature of the Earth's surface as well
Explanation:
The second one because the zeroes in the middle count. 2.0002
Infra-red radiation has a slightly longer wavelength than red light ...
the longest wavelength that is visible to the human eye.
Although infrared can't be detected by the eye, we do have other
receptors that CAN detect it. They are some of the nerve endings
in our skin. When infrared radiation hits these, it produces the feeling
of warmth. Infrared radiation carries heat energy.
Explanation: The first one
Source: it literally has fusion in the name
Answer:
-150 N
Explanation:
(Newton's second law) F=ma
Sum of forces in Y direction= (+200 N)+(-200 N)= 0...
forces cancel, object does not accelerate up/down
Sum of forces in X direction= (+65 N)+(-65 N)+(-150 N)
= -150 N
notice that the +/- 65 components cancel, leaving a net force of 150 N in the LEFTwards direction (which is typically defined as negative)
Overall, the net force is -150 N
