Answer: 7750 J
Explanation:
Mechanical energy is potential energy added to kinetic energy.
5000 + 2750 J = 7750 J
Because by definition a wave travels at the same speed through any given medium, A, C, and D, are all out. B is true, though. Frequency and wavelength can change within a medium itself. Therefore, B, both its frequency and wavelength, is the answer you desire.
Answer:B
Explanation:
For the ball dropped From a tall ball building the direction of acceleration is downward and its magnitude is
For the ball thrown upward towards the dropped ball the direction and magnitude of acceleration is same i.e. downwards as gravity always acting downward with constant magnitude.
Thus option B is correct
Answer:
Geothermal power can provide consistent electricity throughout the day and year - continuous baseload power and flexible power to support the needs of variable renewable energy resources, such as wind and solar. Sustainable Investment.
