A 4.2-kg block of ice originally at 263 K is placed in thermal contact with a 13.7-kg block of silver (cAg = 233 J/kg-K) which i

s initially at 1084 K. The H2O - silver system is insulated so no heat flows into or out of it.1) At what temperature will the system achieve equilibrium?
2) What will be the phase of the H2O at equilibrium?
Solid (ice)
Liquid (water)
Gas (vapor)

Answer:

an example was provided below. switch out my number of 13.4 and plug in 13.7kg and solve

Explanation:

so your equation would be (4.2)(2030)(10)+(4.2)(3.33x10^5) + (4.2)(4186)(T-273)=(13.7)(233)(1075-T)

A ball of mass of 0.5kg is dropped from a height of 2m.
erastovalidia [21]

Answer:

6.3m/s

Explanation:

Given parameters:

Mass of the ball  = 0.5kg

Height  = 2m

Unknown:

Velocity when the ball hits the ground  = ?

Solution:

Since the potential  energy is transformed into kinetic energy;

            P.E  = K.E

              mgh  = \frac{1}{2} m v²

     cancelling m;

               gh  =  \frac{1}{2} v²

                v² = 2gh

                v  = √2gh

Insert the parameters and solve;

               v  = √2gh  = √ 2 x 9.8 x 2  = 6.3m/s

An unbalanced force gives a 2.00 kg mass an acceleration of 5.00 m/s? What is the force applied to the object?​
valentinak56 [21]

Answer:

10N

Explanation:

Equation: ΣF = ma

Fapp = ma

Fapp = (2kg)(5m/s^2)    (im guessing you mean 5.00 m/s^2 not m/s)

Fapp = 10*kg*m/s^2

Fapp = 10N

What is the most appropriate SI unit to express the speed of a cyclist in a 10-km race? km/s cm/h km/h mm/s
Murljashka [212]
You sure wouldn't want something like cm/s or (yikes cm/hr). You want a reasonable number for sports usually between 0 and 100

Km / hour would be a good choice.

The next town to where I live is 25 km away. On a good day, I can make it there in about 3/4 of an hour.

Speed = 25 km / 0.75 hour = 33.3 km/hour. That's actually a little fast most of the time. But you should understand what I mean.
