Answer:
250N
Explanation:
Given parameters:
Time = 4s
Momentum = 1000kgm/s
Unknown:
Force = ?
Solution:
To solve this problem, we use Newton's second law of motion;
Ft = Momentum
F is the force
t is the time
So;
F x 4 = 1000kgm/s
F = 250N
Explanation:
Dark Energy. Dark Energy is a hypothetical form of energy that exerts a negative, repulsive pressure, behaving like the opposite of gravity. It has been hypothesised to account for the observational properties of distant type Ia supernovae, which show the universe going through an accelerated period of expansion
-- Conserve. Don't use more than we need. There isn't any more of it.
-- Conserve. Don't pollute what we have. There isn't any more of it.
Of course, what we REALLY need to do is <u><em>convince</em></u> great numbers of people to go along with these suggestions. Otherwise it won't work.
Torque <span>is defined as the turning effect of force about the axis of rotation. In short it is a moment of force. It is represented by </span>τ. <span>The amount of torque required to produce an angular acceleration depends on the distribution of the mass of the object. It is calculated as follows:
</span><span>torque = (moment of inertia)(angular acceleration)
</span>torque = 1.00 ( 100 )(1/60) / 10
torque = 0.1667 <span>N∙m
</span>
Answer:
The net force and the acceleration on the falling skydiver is upward
Explanation:
An upward net force on a downward falling object would cause that object to slow down. the skydiver this slows down. As the speed decreases, the amount of air resistance also decreases until once more the skydiver reaches a terminal velocity.
