Answer:
resultant is a single force that can replace the of a number of forces , equililbrant is a force that is exactly opposite to resultant
Explanation:
Answer:
Explanation:
The distance is the same in the experiment and using the differents times can find the velocities so
Now the experiment can use the equations of tension in simple pendulum
Now to determinate the mass using the formula of force of gravity
Solve to Mm
Speed = distance / time
Speed = (33 cm) / (2min 20sec)
Speed = (0.33 m) / (140 sec)
<em>Speed = 0.0024 m/s</em>
Speed = (0.0024 m/s) x (3600 sec / 1 hr) x (1 km / 1000 m)
Speed = (0.0024 x 3600 / 1000) (m-sec-km / sec-hr-m)
<em>Speed = 0.0085 km/hr</em>
Answer:
A rock dropped from the ceiling of a truck's cargo bay, with the truck moving at constant velocity, the rock strikes the floor exactly below the midpoint of the ceiling.
Explanation:
An object moving at a constant velocity, is changing its displacement at an equal time.That is, the object is moving on a straight line at a constant speed.
Also an object with a constant velocity is not accelerating, since acceleration is the change in velocity with respect to time.
Therefore, A rock dropped from the ceiling of a truck's cargo bay, with the truck moving at constant velocity, the rock strikes the floor exactly below the midpoint of the ceiling.
Answer:
b
Explanation:
the answer is b because if you do the math it equals to b
