Answer:
150
Explanation:
15m/s×10s= 15m/a
and that is the correct answer
Answer:
v = 9.67 m/s
Explanation:
As we know that acceleration is rate of change in velocity
so it is defined as
here we know that
now we have
integrate both sides we have
here we know that
Answer:
866.92 N
Explanation:
mass of shark, m = 92 kg
density, d = 1040 kg/m^3
Volume, V = mass / density
V = 92 / 1040 = 0.08846 kg/m^3
The lift force is the buoyant force acting on the shark is
Lift force = Volume x density of water x g
Lift force = 0.08846 x 1000 x 9.8
Lift force = 866.92 N
Thus, the lift force is 866.92 N.
Answer:
The answer is below
Explanation:
The acceleration of a ball rolling down an inclined plane would be greater than that of the acceleration of a ball rolling up if acted upon by a force of equal magnitude. For a ball rolling down an inclined plane, the acceleration due to gravity (gsinθ) acts in the direction of motion of the ball thereby leading to an increase in the acceleration of the ball; while for a balling rolling upwards, the acceleration due to gravity acts in the direction opposite to the motion of the ball thereby leading to a decrease in the acceleration of the ball.
<span>A lens is a piece of glass or other transparent substance with curved sides for concentrating or dispersing light rays, used singly (as in a magnifying glass) or with other lenses (as in a telescope). A binoculars, an eye, and a camera all contains a lens. A mirror does not contain a lens.</span>
