Answer: 143 psig

Explanation:

Given data:

System heat = 50f

Evaporator superheat = 10f

System = r410a.

Solution:

Evaporating pressure of the refrigerant in the system

= system heat - evaporator superheat.

= 50f - 10f

= 40f.

Using the r-410a temperature chart

40f = 143 psig.

When do we say a curvilinear motion is accelerated?​
mel-nik [20]

Answer:

There always is an acceleration in a curvilinear motion, as the velocity vector changes, so always.

An object moves 12 m to the right. If its acceleration was 2 m/s and its final velocity is 25 m/s, find its initial velocity.
scoundrel [369]

Explanation:

by the formula, v²-u²=2aS

S=12m, a=2m/s², v=25m/s, u=?

v²-u²=2aS

25²-u²=2×2×12

-u²=48-625

-u²=-577

u²=577

u=√577

u = 24.02m/s

hope this helps you.

Rafaela is a physical education teacher and has2525 girls and 3535 boys in herclass.She wants to divide the class into teams of
Paha777 [63]

-- The greatest common factor of 2525 and 3535 is 5.

-- So the greatest possible number of teams is 5.

-- Each of the five teams will have 505 girls and 707 boys.

-- Rafaela is a superwoman !  She's handling more kids in that class than there were in my whole high school !

She has 6,060 students in her class, so I'm not surprised that she wants to divide the class up into smaller groups.  

But come on !  She's going to form 5 teams, and she thinks that her job will be easier that way, because each team will have 'only'  1,212 students on it !

And these are all in one class !  If Rafaela is a physical education teacher, then SURELY she's teaching more than one class !

Or maybe not.  I'll betcha whenever Rafaela is teaching her physical education class, all the other teachers are taking it easy, because Rafaela is responsible for every student in the school that hour.

And possibly several OTHER schools in town too.

108J of work was done on a closed sysem. During this phase of the experiment, 79J of heat was added to the system.What was the t
skelet666 [1.2K]

The change in internal energy of the system is +187 J

Explanation:

According to the first law of thermodynamics, the change in internal energy of a system is given by the equation:

\Delta U = Q + W

where

\Delta U is the change in internal energy

Q is the heat absorbed by the system

W is the work done on the system

For the system in this problem, we have

W = +108 J is the work done on it

Q = +79 J is the hear added to it

So, the change in internal energy is

\Delta U = 108 + 79 = +187 J
