Answer:
A
Explanation:
I think that if the object is a conductor, it would want all of that electricity, attracting the object
Answer:
Explanation:
What shows that an object is accelerating
1. If the velocity is increasing.
From equation of motion
a = ∆v / t
So, if the velocity increases with time, the acceleration increases. But if it decreases with time, it decelerating.
2. Also, from newton second law,
F = ma
a = F / m
Where a = acceleration
F is force applied
m is the mass
So, if the force is increase and the mass is reduced, then the acceleration is increase.
3. Also, in. Circular motion,
a = w²r
Where
a is linear acceleration
w is angular speed
r is the radius.
So, when the angular speed is increased, then the linear acceleration is increased.
Answer:
Its gravity potential energy is 39,240 J
Explanation:
The gravity potential energy of a body on the earth's surface is the energy a body under the influence of gravity possesses by virtue of its elevation from the surface of the earth.
We can calculate the GPE using this formula
from the problem given, we have m= mass= 20 kg
g = gravitational constant = 9.81m/s2
height = 200m
Hence, Its gravity potential energy is 39,240 J
What's going on is that the water in the straw is pushed into the straw by the air pressure outside of the straw. As long as the pressure outside is able to overcome the force of gravity, the liquid will stay in the straw.
Answer:
Elbow Lake
Explanation:
An oxbow lake is a stagnant lake that forms along a winding river due to soil erosion resulting in an abandoned stream, cut off from the river. An oxbow lake begins as meander or a curve in a river after some time, the curve becomes larger as a result of erosion and hydraulic action.
