You watch a carpenter down the street hammering nails in a roof and note that the sound and sight are synchronized perfectly. Then when he stops hammering, you hear one more hammer blow. (a) Suppose that the time delay between the time you see the last blow and the time you hear it is t. Write an equation for the distance between you and the carpenter, (b) Calculate your answer to the above for a time delay of 0.80 seconds. ​

mass 500 = 500xmass 1

volume pile = 0.3x0.2x0.048

density=mass/volume= 500xmass 1/0.3x0.2x0.048

wind moving at higher speeds will transfer more energy to the water, resulting in stronger waves.

probably not the "magnets"in the magnet, so to speak, are thought to be electrons orbiting in shells. vurrent loops two sides to the loop

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
