Answer:
F = 789 Newton
Explanation:
Given that,
Speed of the car, v = 10 m/s
Radius of circular path, r = 30 m
Mass of the passenger, m = 60 kg
To find :
The normal force exerted by the seat of the car when the it is at the bottom of the depression.
Solution,
Normal force acting on the car at the bottom of the depression is the sum of centripetal force and its weight.



N = 788.6 Newton
N = 789 Newton
So, the normal force exerted by the seat of the car is 789 Newton.

Answer:</h2>
If a car is rounding a flat curve, it experiences a centripetal force that pulls it towards the center of the circle it is rotating in.
Now,
The centripetal force can be balanced by the centrifugal force caused due to the acceleration of the body at the high speed which counters the centripetal force and in turn <u>prevents the car from slipping down the curve.</u>
So,
If the car doesn't hit the gas then the <em><u>car will fall down from the curve</u></em> as the Centripetal force will exceed the Centrifugal force of the car.
However, if the car doesn't hit the brake then the <em><u>car will maintain it's position on the flat curve</u></em> track as the centrifugal force will counter the effect of centripetal force directed towards the center.
Density = mass/volume. 5000/50= 100 grams per cubic centimeter. No substance on Earth has anywhere near that density. Tops is about 20 for osmium and gold.
Frequency = speed ÷ wavelength
= 330m/s ÷ 2.5m
= 132 Hz
Gravitational potential energy is the energy stored in an object due to its height above the Earth.
Explanation:
Gravitational potential energy is an energy that an object has as a result of its position in a gravitational field.
For an object which is near to Earth surface is gravitational acceleration is considered to be constant at 9.8 m/s².
Gravitational potential energy is also defined as the amount of work done to move an object having certain mass from one point to another point against gravitational force. It is calculated as mass multiplied by height to which an object is moved.
Some examples are water stored in a dam, ball kept on the top of a ramp, book kept of a shelf, etc.
