Answer:
55,42 J
Explanation:
Since the height of the room is 3.45 m (distance between the floor and the ceiling) the difference between this value and the length of the rope 1.19 m; it will be equal to (3.45-1.19) =2.26 m. If we take as a reference point (Ep=0) the floor of the room, then the potential energy will be equal to Ep = M * g * h, replacing values in this equation (2.5 kg * 9.81 m/s2 * 2.26 m) will be 55,42 (N * m) or Jules.
Centripetal acceleration is given as
![a_c = \frac{v^2}{R}](https://tex.z-dn.net/?f=a_c%20%3D%20%5Cfrac%7Bv%5E2%7D%7BR%7D)
here we know that
v = speed of the car
R = radius of curvature of the car
now here we can see that the acceleration of car directly depends on the square of the speed
so here if speed of the car is tripled then centripetal acceleration will be increased by square times
so here centripetal acceleration is increased by 9 times if speed is tripled
Answer:
if the friction was removed from the ramp, the acceleration would drasticly increase, making it hard to stop.
Explanation:
Answer:
The magnetic flux is generated when there is change in the magnitude of the magnetic field as well as its direction. ... If the magnetic field is parallel to the place of the area exposed then the magnetic flux generated is zero when the magnetic field is not zero.
