The amount of heat that is needed to raise the temperature of 1 kilogram of some material by one degree Celsius is called the blank of the material

0.55x745.7j and a calculator

another example of kinetic energy would be,

kinetic energy   >     moving energy

grav force prop 1/r squared 2r all squared is 4rsquared 1/4rsquared quartered

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
