Answer:
For northern hemisphere, the altitude will decrease. For southern hemisphere, the altitude will increase
Explanation:
Because of the spherical shape of the Earth the altitude (separation from the horizon in degrees) of the celestial pole changes as per the latitude of the place. The altitude of the celestial pole is equal to the latitude of the observer.
If the observer is in the northern hemisphere and moves south the altitude of the celestial pole will decrease.
If the observer is in the southern hemisphere and moves south the altitude of the celestial pole will increase.
Answer:
60mph=26.8224meters per second
Explanation:
Answer:
Right shoe
Explanation:
Let the mass and velocity of incoming puck be m and v respectively.
Momentum of the colliding puck will be mv
In case of first case , the momentum of puck becomes zero so change in momentum after collision with left shoe
= mv - 0 = mv
If time duration of collision be t
rate of change of momentum
= mv / t
This is the force exerted by puck on the left shoe .
Now let us consider collision with right shoe
momentum after collision with right shoe
- mv
change in momentum
= mv - ( - mv ) = 2mv
If time duration of collision be t
rate of change of momentum
= 2mv / t
This is the force exerted by puck on the right shoe .
Since the force on the right shoe is more , this shoe will have greater speed
after collision.
