Answer:
24 hours
Explanation:
If a satellite is in sync with Earth then the period of each satellite is 24 hours.
Angular velocity is given by
The angular velocity of the satellite is
Answer:
when an object kept at some height and having some mass then ,when it falls down then shifting of energy takes place
Answer:
Explanation:
My speed after the interaction will depend upon the impulse the ball will make on me . Now impulse can be expressed as follows
Impulse = change in momentum
change in momentum in the ball will be maximum when the ball bounces back with the same velocity which can be shown as follows
change in momentum = mv - ( - mv ) = 2mv
So when ball is bounced back with same velocity , it suffers greatest impulse from my hand . In return , it reacts with the same impulse on my hand pushing me with greatest impulse according to third law of motion. this maximizes my speed after the interaction.
Answer:
Three, the liquid in the man's cup, the stove is solid, and the air around them is a gas
Explanation:
Finding acceleration= final speed-initial speed/time taken (or A=V-U\T)
Finial speed= 27.8s
Initial speed= 0s
Time taken= 5.15
So..
27.8-0/5.15= 5.40m/s (rounded to two decimal places)
