Answer:
I would have to say the answer is D
Explanation:
because the angle is being changed using the ray box.
The ozone layer traps heat from the sun's heat. only three-fourths are reflected back out into space by the ozone layer. the greenhouse effect traps carbon dioxide and so does the ozone layer.
600 g=.6 kg
mgh=pe
.6(10)(1)=6
therefore, the basketball will have roughly 6 joules of ke.
Answer:
The value of current through the rod becomes half
Explanation:
As per Ohm's law we know that the current through a resistor is given as
here we know that
here we know that the length of the cylinder is L and area is A so the value of current through the rod is given as
now we have change the length of the conductor to twice of initial value and rest all parameters will remain the same
so we will have
now from above two equations we have
so new current will become
Answer:
(c) The wall exerts a greater force on the 2 kg ball than on the 5 kg ball since the force from the wall on each ball is equal to the force that each ball exerts on the wall.
Explanation:
According to Newton's third law of motion,"action and reaction are equal and opposite".
If a 2 kg ball exerts a force of 10,000 N on a wall, the wall will also exert a force of 10,000 N on the 2 kg ball but in opposite direction.
Similarly, If a 5 kg ball exerts a force of 5,000 N on a wall, the wall will also exert a force of 5,000 N on the 5 kg ball but in opposite direction.
Regardless of mass of the ball, the wall will exert equal force with which the ball collide with it.
Therefore, the wall exerts a greater force on the 2 kg ball than on the 5 kg ball since the force from the wall on each ball is equal to the force that each ball exerts on the wall.
