Please help this is due in 10minutes 345 g of silver at 300°C is placed in a 125 g Iron calorimeter that contains 400 g of water at 20.0°C. What is the final temperature?
O 115 ° C
O 32.5 °C
O 21.3 °C
O 35.7 °C

the electric field is a “force field” around a charged object that illustrates the direction the electric force would push an imaginary 

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

= initial pressure

= final pressure = 2

= initial volume

= final volume = /4

= initial temperature = 20 c = 20 + 273 = 293 k

= final temperature = ?

using the equation
