As a pendulum swings back and forth, its total energy is 16 j. what is its kinetic energy at 3/4 its maximum height?

KE = 4 J

Explanation:

As we know that for swinging pendulum the total energy of the pendulum is always conserved

so here its total energy is

now when the pendulum will reach to its maximum height then its total energy will convert into potential energy

so here at 3/4 of its maximum height the potential energy will also become 3/4 times of total energy

so it is given as

now by energy conservation we will have

K = 4 J

hi,

what occurs during a solar eclipse?

there are small tides across earth.

the moon is between earth and the sun.

p.s. im not sure if the first answer is correct because during a solar ecliphse there are spring tides and i dont know if they are the same.
