Answer:
it have Potential energy
Explanation:
given data
Drag the pendulum to an angle 30∘
to find out
what form of energy does it have
solution
we know that pendulum start no kinetic energy when it release from any rest position then in starting it have potential energy only so that when pendulum is angle 30∘ at some height from ground so when it start it have potential energy same as in starting.
we know that the total energy is always conserve
so it have potential energy
Hmmm... I’d say that’s pretty accurate. Good job! Well wishes on whatever it is you’re doing.
Answer:
thermal, hot equals thermal and such
Answer: wavelength is equal to 150 m
Explanation: To solve for the wavelength we will use the formula of frequency which is the ratio of wave speed per unit wavelength and derive to find wavelength.
wavelength = wave speed / frequency
= 1500 m/s / 10 Hz
= 150 m
