Evidence that seismic waves transfer energy without transferring matter: Seismic waves do not transfer matter because the waves travel away from the faults because the movement in the crust occur along the faults as the seismic waves continue to travel away.
Answer:
The answer is below
Explanation:
The speed of the boat in still water is perpendicular to the speed of the water flow. Therefore the speed relative to the ground (V), the speed of flow and the speed of the boat in still water form a right angled triangle. Hence the speed relative to the ground is given as:
V² = 56² + 126²
V² = 19012
V = 137.9 m/s
Answer:
Explanation:
Total tension must support the weight of the child and provide the necessary centripetal force.
2T = m(g + v²/R)
2(414) = 35.0(9.81 + v²/3.02)
828 = 35.0(9.81 + v²/3.02)
23.65 = 9.81 + v²/3.02
13.847 = v²/3.02
41.81 = v²
v = 6.47 m/s
F = 2(414) = 828 N (ignoring the weight of the chains and seat)
Answer:
An electric motor converts electrical energy into mechanical energy. The process is as follows:
D. When current flows through the motor, it powers electromagnets that are attracted and repelled by the poles of permanent magnets in the motor. The movement of the electromagnets turns a rod in the motor, which makes the mechanical energy available.
