-- The area under a velocity/time graph, between two points in time, is the difference in displacement during that period of time.
-- The area under a speed/time graph, between two points in time, is the distance covered during that period of time.
Answer:
here there is also an electric attraction force
Explanation:
In the insulating bodies the charges are not mobile, so when one of the body is charged periodically or gained some electrical charges.
When the body is neutral the net number of electric charges is zero. When the loaded body touches it, it repels the charges of the same sign whereby the induced load is of a different sign and the two adhered sheets are attracted.
With this explanation it is equivalent to that of the ball and the wall, so here there is also an electric attraction force
Answer: Mercury is rarely used in thermometers that take body temperatures because it is toxic, accidentally if by any chance a thermometer breaks orleaky, mercury gets inside body and can cause harm.
Explanation:
20 N
Newtons third law states that any action (pulling the sled) has an equal and opposite reaction (the sled pulling back on you).
Think about pulling a sled on really slippery ice, you would pull yourself toward the sled just as much as the sled toward you.
Answer:
distance travelled 7 metres and
displacement 3 metres
Explanation:
Distance travelled is the total diatance travelled by you which is 2m + 5m = 7m
Displacement is the shortest distance between two points start and stop which is 3m.
