Answer:
The rate of energy coming from the Sun changes slightly day to day. It has been suggested that changes in solar output might affect our climate both directly, by changing the rate of solar heating of the Earth and atmosphere, and indirectly, by changing cloud forming processes
The Sun warms our planet, heating the surface, the oceans and the atmosphere. This energy to the atmosphere is one of the primary drivers our weather. Our climate is also strongly affected by the amount of solar radiation received at Earth.
Answer: The brain is the vital organ in humans and each part of brain exhibit a distinct function.
Explanation:
The frontal part of the brain is responsible for controlling the cognitive skills, movement of the body, emotions, memory, judgement, sexual activity, linguistic skills, and others. It controls the behavior. It is the overall control panel of the human body. If the frontal lobe is damaged then this can negatively affect the human personality. The person suffers from difficulty in concentrating as well as planning.
Answer:
The correct answer is option a.
Explanation:
Power output refers to the power exerted at the time of performing physical activities. Power output is one of the best means of determining athletic performance at the time of exercise or any physical activity. When the athlete jumped over the treadmill, his output power enhanced abruptly, while the power input enhanced slowly over a duration of one to two minutes.
This is evidenced by Doppler
shift effect. This is the phenomenon where waves that are coming from an object
that is accelerating towards your direction are heard at a higher frequency than that of
objects moving away from you. This is the same for light (which also has
wave-like properties). When observing distant galaxies, astronomers discovered that
they all showed to be redshift (change in the frequency of light towards red
color). This means that all galaxies are moving away from each other because
the universe is expanding.
