Which statement CORRECTLY describes the energy transformation as the pendulum swings from point A to point B? A

The kinetic energy of the pendulum is highest when the washer is at point A and decreases to a minimum at point B.

B

The potential energy of the pendulum is highest when the washer is at point A and decreases to a minimum at point B.

C

The kinetic energy of the pendulum remains the same as it moves between the two points labeled A.

D

The potential energy of the pendulum remains the same as it moves between the two points labeled A.

speed

ratio of distance traveled to time interval

net force

vector sum of forces on object

object

source of diverging light rays either luminous or illuminated

don't remove my answer im trying my best to answer them

explanation:

layers of the earth affect the waves and these effects are seen on instruiments such as seimometers

compass can be used day and night, cloudy or sunny

the minimum constant speed at which she can catch the train is 2.7 m/s

given:

acceleration = 0.6

time = 4.5 s

to find:

velocity = ?

formula used:

from 1st kinematic equation we get,

v = u + at

u = initial speed of train = 0 m/s

v = final speed of the train

a = acceleration of the train

t = time

solution:

from 1st kinematic equation we get,

v = u + at

u = initial speed of train = 0 m/s

v = final speed of the train

a = acceleration of the train

t = time

v = 0 + (0.6 × 4.5)

v = 2.7 m/s

the minimum constant speed at which she can catch the train is 2.7 m/s
