Answer:
Option A
Explanation:
From fundamental equation of motion
where v is the final velocity, u is the initial velocity, a is the acceleration of the body and s is the displacement.
Since the initial velocity is zero
Making acceleration, a the subject of the formula then
Substituting 5 m/s for v and 2.5 m for s then
When sugar is first heated, it begins to melt. As it melts its color starts to change from white to golden brown, and then to dark brown (if you continue heating it). If you apply heat for even longer, it becomes black and gives off unpleasant fumes.
Answer:
A) total intensity = 5x10^-4W/m2
B) total intensity = 5.34x10^-4W/m2
Explanation:
Detailed explanation and calculation is shown in the image below
If you stay on or near the surface of Earth, then the acceleration due to gravity
is constant. It's 9.807 meters per second squared. (rounded)
Explanation:
because the moon has less mass than earth, the force due to gravity at the lunar surface is only about 1/6 that on earthso,the weight of a body on earth is 6×5N =30N
