The correct answer is: The voltage drop across
is
45V.Explanation:First you need to find the total current of the circuit, which is:
According to Ohm's law:
V = I * R
I = V/R --- (1)
Where
R = Total Equivalent resistance of the circuit
V = Total Voltage = 90V
I -= Total Current
First let us find the equivalent resistance:
Now plug in the values in (1):
(1) => I = 90/30 = 3A
Now that we have current of the circuit, we can now find the voltage
drop across
= 15 ohms using:
Where
is the voltage drop across resistor 5;
Answer:
Infrared
Explanation:
This is the electromagnetic spectrum just above the visible light spectrum with higher energy (and higher frequency). This electromagnetic radiation is responsible for feeling the heat when you place your hand close to the side of a fire. It is also harnessed in night vision where bodies that emit some form of heat are visible due to their emission of IR.
Answer:
The answer to your question is: a = 2 m/s²
Explanation:
I' ll solve it in this way, tell me if I'm right. Because we need to consider that in the moon there is no gravity.
Data
F = 50 N
a = 4.0 m/s²
Moon
F = 25 N
a = ?
Formula
F = m x a
First, calculate the mass
m = F / a
m = 50 / 4
m = 12.5 kg
Now, calculate the acceleration
a = F / m
a = 25 / 12.5
a = 2 m/s²
On the off chance that a 2.45 GHz microwave flag is by one means or another radiating from your microwave oven, that is exceptionally perilous and you ought to have it settled or supplanted promptly. A 1000 Watt microwave oven radiating energy into the nearby environment can, contingent upon conditions, make you lose awareness in around 12 to 15 minutes of presentation at a separation of around 10 feet.
Red or violet is the color with the most energetic photons!! Hope this helped!!
