Answer:
As given that the car maintains a constant speed v as it traverses the hill and valley where both the valley and hill have a radius of curvature R.
(i) At point C, the normal force acting on the car is largest because the centripetal force is up. gravity is down and normal force is up. net force is up so magnitude of normal force must be greater than the car's weight.
(ii) At point A, the normal force acting on the car is smallest because the centripetal force is down. gravity is down and normal force is up. net force is up so magnitude of normal force must be less than car's weight.
(iii) At point C, the driver will feel heaviest because the driver's apparent weight is the normal force on her body.
(iv) At point A, the driver will feel the lightest.
(v)The car can go that much fast without losing contact with the road at A can be determined as follow:
Fn=0 - lose contact with road
Fg= mv²/r
mg=mv²/r
v=sqrt (gr)
Answer:
They seek the path of lease resistance between opposite magnetic poles, in a single bar magnet they attempt to form closed loops from pole to pole and never cross each other.
Answer:
Explanation:
As we know that the equation of particle position is given as
Now the speed of the particle is given as
now we know that potential energy and kinetic energy is equal
so we have
so we will have
Stratigraphy is a discipline aimed at identifying layers of sedimentary and/or volcanic rocks, which is mainly based on the principle of superposition.
<h3>What is stratigraphy?</h3>
Stratigraphy refers to the science based on the identification of different layers in sedimentary and/or volcanic rocks.
Stratigraphy as a discipline is mainly cemented on the principle of superposition, which indicates that older layers of sediment are located on the bottom.
Stratigraphy allows us to understand the geological past of a region, which is important in different disciplines such as biogeography.
