Changes in solar position influence the intensity of radiation on a horizontal surface because Energy concentration is greatly affected by changes in solar position. Energy intensity is greater when solar position is high. This concentrates more energy per unit area.
What determines the intensity of solar radiation?
The angle of the sun determines solar irradiance. The greater the angle, the lower the solar intensity. The lower the angle of the sun, the larger amount of ozone the light has to pass through.
What affects the intensity of solar energy?
The main parameters affecting the intensity of solar radiation are the zenith angle zeta of the sun, the water vapor content w of the atmosphere, and Schupp's turbidity coefficient B.

Answer:
1.2826 x 10^-13 m
Explanation:
Here, k be the kinetic energy and m be the mass
K = 50 KeV = 50 x 1.6 x 10^-16 J = 80 x 10^-16 J
m = 1.67 x 10^-27 kg
λ = 1.2826 x 10^-13 m
The major shortcoming of Rutherford's model was that it was incomplete. It did not explain how the atom's negatively charged electrons are distrubuted in the space surronding its positively charged nucleus. A form of energy that exhibits wavelike behavior as it travels through space
The index of refraction of light varies from color to color. TRUE.
Answer:
Acceleration = 4.8 m/s²
Explanation:
Given:
Change in velocity = 19 m/s
Change in time = 4 s
Find:
Acceleration
Computation:
Acceleration = Change in velocity / Change in time
Acceleration = 19/4
Acceleration = 4.8 m/s²
Positive acceleration
