<span>The answer is D. mountains have been eroding for millions of years. The Appalachian Mountains is an older group of fold mountains. It is much older than the Himalays that do not exibit this rounded shape. As tectonic forces enable mountain building, forces of weathering, erosion and mass wasting are constantly eating away at them. </span>
Answer:
Explanation:
electric field = 2170 N/C
now the speed of the charge particle is given as
here we know that charge particle moves without any deviation
so we will have
now magnetic field in this region is given as
Now another charge particle enters the region with different speed and experience the force upwards
Answer:
60kgm/s
Explanation:
Given parameters:
Mass of frisbee = 5kg
Final speed = 12m/s
Unknown:
Impulse of the frisbee = ?
Solution:
The impulse of the frisbee is the same as the change in momentum.
It is given as:
Impulse = mass (Final velocity - Initial velocity)
Impulse = 5(12 - 0) = 60kgm/s
Steps:
1)Data:
Mass of the football player=m=65kg
Velocity of football player=v=5m/s
2)Formula:
P=mv
Or
Momentum=(mass of the object)(velocity of the object)
3)Calculation:
P=(65)(5)=325 kgm/s
Hope it helped!
