Answer:
the answer is kg
Explanation:
because the s.i unit for mass is kilogram
Answer:
Explanation:
An object is at rest along a slope if the net force acting on it is zero. The equation of the forces along the direction parallel to the slope is:
(1)
where
is the component of the weight parallel to the slope, with m being the mass of the object, g the acceleration of gravity, 
the angle of the slope
is the frictional force, with 
being the coefficient of friction and R the normal reaction of the incline
The equation of the forces along the direction perpendicular to the slope is
where
R is the normal reaction
is the component of the weight perpendicular to the slope
Solving for R,
And substituting into (1)
Re-arranging the equation,
This the condition at which the equilibrium holds: when the tangent of the angle becomes larger than the value of , the force of friction is no longer able to balance the component of the weight parallel to the slope, and so the object starts sliding down.
There are no following but less red blood cells would make you tired because you can carry as much oxygen and more white blood cells could cause infection if the start attacking you. It could also give you bone marrow cancer if there are too many white blood cells.
Kicks it up into the air and it falls back down to her, or it could be it was kicked and bounced off another surface like a wall and the force returns it to her.
Potential energy is converted to kinetic energy. Firstly, the question says nothing about the use of electricity, an electric current, or any sort of voltage, so any answer about electrical energy is irrelevant. Secondly, the key is to understand what potential and kinetic energy mean. Potential energy is the energy that an object has when it is at rest. Kinetic energy is the energy of motion; it is potential energy that has been converted to energy used to do movements, so when a roller coaster falls, its potential energy at the top is converted to kinetic energy as it rolls down.
