Answer:
the light creates sorta a mixture of all the colors on the white index card.
Answer: B
Explanation:
Newton's first law it's law of inertia.
An object at rest will remain at rest (or an object in motion in a straight line at a constant velocity will remain that way) unless it is acted by an unbalanced force.
In A for the ball to slow down and stop, an external force (like friction with air or the floor) needs to be taken in consideration.
In B we can see how we need to make a force on the wagon to make it move.
In C we have an other Newton 's law, force equals mass times acceleration (2nd law)
In D we can see how it does not move because the forces on the box are balanced.
Explanation:
It is given that,
Density of asteroid,
Mass of asteroid,
We need to find the diameter of the asteroid. The formula of density is given by:
V is the volume of spherical shaped asteroid,
r = 2441311.12 m
Diameter = 2 × radius
d = 4882622.24 m
or
Hence, this is the required solution.
The balloon was 30.65 meters above ground.
ANSWER: A
Answer:
S = V t - 1/2 a t^2 a here is negative due to deceleration
S = 4 * 8 - 1/2 * 64 = 0
The object just returns to its original starting point
It started out at 8 m/s which was reduced to 0 m/s after 4 sec
In 4 more seconds it was moving at -8 m/s, just the opposite of where it started
