The magnitude of the circuit current is 0.20 A. The value of the current in the circuit is found with the help of the ohm's law.
<h3>What is ohm’s law?</h3>
Ohm's law claims that the voltage across a conductor is directly proportional to the current flowing through it.
All the resistance combined in the series so that the equivalent resistance is;
This current-voltage connection may be expressed mathematically by the Ohm's Law;
V=IR
Hence, the magnitude of the circuit current is 0.20 A.

Force (in newtons) = mass (in kg) x acceleration (m/sec)
Therefore Force = 3kg x 5m/s ==> 15 newtons
----------------------------------
75 newtons = m x 10 ==> 7.5kg
I believe...?
Answer:
a. reflection of all the light at a surface.
Explanation:
When light rays passing from the denser medium to the rarer medium and the angle of incidence is greater than the critical angle, the refraction of light does not take place and the incident ray is totally reflected back into the denser medium. This phenomenon is called total internal reflection.
There are two conditions that need to be fulfilled in order for the total internal reflection to take place:
1. The ray of light should be incident from denser to rarer medium.
2. The angle of incidence should be greater than the critical angle.
Therefore, the correct option will be:
<u>a. reflection of all the light at a surface.</u>
Answer:
So, the evaporating pressure of the R410A = 118 psig
Explanation:
Solution:
For R410A system:
Data Given:
Evaporator Outlet Temperature = 50°F
Evaporator Superheat = 10°F
Required:
Evaporating Pressure in the system = ?
For this, first of all, we need to calculate inlet temperature on R410A system from the given value of outlet temperature.
Evaporator inlet temperature is the difference of outlet temperature and evaporator superheat.
Evaporator inlet temperature = Outlet Temperature - Evaporator Superheat
Evaporator inlet Temperature = 50°F - 10°F
Evaporator inlet Temperature = 40°F
Now, as we have the inlet temperature and the R410A system. We can consult the pressure temperature chart or PT chart, which I have attached and highlighted the value of evaporating pressure for 40°F inlet temperature.
So, the evaporating pressure of the R410A = 118 psig
