Here is the answer!!!!!!!
(a) Determine the circumference of the Earth through the equation,
C = 2πr
Substituting the known values,
C = 2π(1.50 x 10¹¹ m)
C = 9.424 x 10¹¹ m
Then, divide the answer by time which is given to a year which is equal to 31536000 s.
orbital speed = (9.424 x 10¹¹ m)/31536000 s
orbital speed = 29883.307 m/s
Hence, the orbital speed of the Earth is ~29883.307 m/s.
(b) The mass of the sun is ~1.9891 x 10³⁰ kg.
<span>The image formed by a plane mirror is always virtual (meaning that the light rays do not actually come from the image), upright, and of the same shape and size as the object it is reflecting. A virtual image is a copy of an object formed at the location from which the light rays appear to come.</span>
Answer:
Hydroelectric power
Explanation:
The Hydroelectric power is more green than the thermal power. It will not give out the smoke that thermal power will
Answer:
a. Relative humidity increases: a decrease in temperature without a change in the amount of water vapor in the atmosphere.
Explanation:
Colder air requires less humidity to saturate compared to warmer air. Therefore, the relative humidity depends on the air temperature. If the temperature drops and the water vapor content remains the same, relative humidity increases. If the temperature increases and the water vapor content remains the same, relative humidity decreases. Additionally, a greater amount of water vapor in the air increases the relative humudity.
