Work done is equal to force by distance; so you take the force exerted, in newtons, and multiply that by the direction it's moved (from the starting point in a line, not along the path it's taken.)
Answer:
dry ice, air fresheners, polar evaporation, arsenic treatment
Answer:
The time taken by the satellite to orbit earth at its surface, t = 1.66 hr
Explanation:
Given data,
The velocity of the satellite, v = 15000 miles/hr
The distance of travel, d = 24901 miles,
It is equal to the circumference of earth,
So the time taken by the satellite to orbit earth at its surface,
v = d/t
t = d/v
Substituting the given values in the above equation,
t = 24901 / 15000
= 1.66 hr
Hence, the time taken by the satellite to orbit earth at its surface, t = 1.66 hr
Answer:
404.4 m
Explanation:
Converting the initial speed from km/h to m/s then

The acceleration is resolved as shown in the figure hence
deceleration of the truck along the inclined plane will be
where g is acceleration due to gravity
Substituting g with
then

Using kinematic equation
and making s the subject then
where v and u are final and initial velocities respectively
Substituting 0 for v, 38.89 m/s for u and
then
