Roller coasters are not infinite. Builders/Makers of the ride have to pay a lot for those rides.
Answer:
The angular position of the wheel after 2.7 seconds is θf= 11.35 rad.
Explanation:
θi= 8.8 rad
ωi= 0 rad/seg
α= 0.7 rad/seg²
θf= θi + ωi * t + α * t² / 2
θf= 11.35 rad
Answer: Zero
Explanation:
In electromagnetic wave, the magnetic and electric field are perpendicular to each other as well as perpendicular to the propagation wave. Both are always in a phase.
When the electric field is minimum, the magnetic field is also minimum and when the magnetic field is maximum, the electric field is also maximum. They are both in the same phase. Therefore, the phase difference between the oscillation of the electric field and that of the magnetic field is zero.
Answer:
A horse pushes the ground in a backward direction. According to Newton’s third law of motion, a reaction force is exerted on the horse in the forward direction. When the horse walks in the forward direction (with the cart attached to it), it exerts a force in the backward direction on the Earth. An equal force in the opposite direction (forward direction) is applied on the horse by the Earth. This force moves the horse and the cart forward. As a result, the cart moves forward.
