Since force is a vector quantity, we can find the net force by determining the resultant force. The equation is written below:
F = √(Fx²)+(Fy)²
where
Fx is the force parallel to the ground
Fy is the downward force
F = √(1.2×10⁻⁶ N)²+(1.27×10⁻⁵ N)²
F = 1.2788×10⁻⁵ N
Then, we apply Newton's second law of motion.
F = ma
a = F/m = 1.2788×10⁻⁵ N/(6×10⁻⁷ kg)
a = 21.31 m/s²
<em>The magnitude of the acceleration is 21.31 m/s². The direction is shown in the picture, which is headed towards southeast.</em>

Answer:
.
Explanation:
Intensity of the electromagnetic radiation is given by
where is the distance from the EM source (the center of the sun, in our case), and
is the power output of the sun and it has the value
Since the radius of the sun in meters is , the intensity
of the electromagnetic radiation at the surface of the sun is
The intensity of the electromagnetic radiation at the surface of the sun is .
