Answer:
Wind blowing across the surface eroded the limestone.
Explanation:
It's kinetic energy as the ball the ball isn't raised above the ground it does not have any gravitational potential energy.
To find the kinetic energy of the ball you will have to use the formula:
KE=0.5 x m x v squared
m being mass and v being velocity
so the calculation is:
0.5 x 2 x 10 x 10= 100J
Answer: An oxbow lake forms after there has been deposition of sediment, by the new cutoff channel flowing adjacent to it, at the entrances of the abandoned bend; this seals the bend off from the rest of the river.
Answer:
The correct answer to the question is;
North
Explanation:
Fleming's left hand rule states that the direction of a magnetic field acting on a current carrying conductor is perpendicular to both the force acting on the current carrying conductor and the direction of the current.
Therefore, since the direction of the current is upward and a force is acting with a direction towards the east of the wire then the direction of the magnetic field is northwards.
<span>For the question "A light shines up from the bottom of a fish pond.
Which diagram shows the correct path of light as it leaves the water of the pond and hits the air?"
The second diagram is the correct answer.
Water has a higher refractive index than air so the ray of light passing from water to air will be refracted away from the normal (the vertical) towards the surface of the water.</span>
