Answer:
the impact on the water varies from different heights, therefore the mass stays the same, yet the force on the water increases from a higher height. A taller height will produce a bigger splash!
Explanation:
Answer:
b.The frictional force and force exerted by the spring scale on the block, because they are a Newton's third-law pair.
Explanation:
Students connect a spring scale to a block on a rough horizontal surface. The students use the spring scale to measure the magnitude of the horizontal force needed to pull the block at a constant speed. Which of the following statements explains why two forces exerted between objects ar equal in magnitude?
a.A The gravitational and normal forces exerted on the block, because they are a Newton's third-law pair.
b.The frictional force and force exerted by the spring scale on the block, because they are a Newton's third-law pair.
c.The normal force and the frictional force exerted on the block, because objects always exert forces of equal magnitude on each other.
d.The frictional forces that the block and the surface exert on each other, because objects always exert forces of equal magnitude on each other.
solution \
the answer will be B
for a body to travel in a horizontal direction, it must be equal in direction to the frictional force which is in opposite direction to the force applied to move the block.
Also Newton's third law of motion must be obeyed , which states that action and reaction are equal and opposite
ONE CAN perform this by doing an ideal experiment
by creating an isothermal system
its like you supply heat to a body and that body is present at very low temperature the amount of heat you supply is equal to the amount of heat lost by that body due to difference in the temperature of the body and the surrounding. heating curve will be constant as there is no change in the internal energy of the system ..
Actually, No. That operation doesn't give you the speed, and that statement is false.
One clue is the units. If you multiply time by distance, you'd get an answer with units of hour-miles or second-meters. These are absurd units, with no physical significance.
Speed = (distance covered) <u>DIVIDED BY</u> (time to cover the distance)
When you divide distance by time, you get an answer with units like "miles per hour" or "meters per second". Without going into a long-winded discussion, I can't PROVE to you that this is actually the correct speed, but these units sure do smell a lot better.
