Answer:
14.3 m/s
Explanation:
velocity equation
v= d/t
v= 60/4.2
v=14.28
round it to 1 decimal place
v= 14.3m/s
Ferromagnetic, paramagnetic, and diamagnetic
In the circuit, the total current is 60 A and the voltage is 240 V. If R1
resistance is 20 Ω, then the R2 resistance would be 5 Ω
<h3>What is resistance?</h3>
Resistance is the obstruction of electrons in an electrically conducting material. The SI unit of the resistance is Ohm
The mathematical relation for resistance can be understood with the help of the empirical relation provided by Ohm's law.
V=IR
where V is the voltage
I is the current
R is the resistance
For the given problem V= 240 V and I = 60 A
R = V/I
R =240/60
R =4 Ω
For calculating equivalent resistance in parallel combination.
1/Re = 1/R1 + 1/R2
1/4 = 1/20 + 1/R2
R2 = 5 Ω
Thus , the R2 resistance would be 5 Ω, therefore the correct answer is option B.

Answer:
digital signals one non-obvious example of a digital signal is a hard disk. Discrete time signals are defined for a discrete set of values, like the samples of a continuous time signal, while digital signals are inherently digital, like the number that crosses a certain bridge every hour.
Explanation:
Analog signals for example, and aneroid barometer uses rotary position as the signal to conveyed by an analog signal, often such a signal is a measured response to changes in physical phenomena, such as sound, light, temperature, position, or pressure.
-It takes air from it's surroundings.
-Compresses the air
-Removes Nitrogen
-Delivers an electric Interface
-Then it delivers the purified oxygen
