Answer:
A voltage-controlled resistor (VCR) is a three-terminal active device with one input port and two output ports. The input-port voltage controls the value of the resistor between the output ports. VCRs are most often built with field-effect transistors (FETs). Two types of FETs are often used: the JFET and the MOSFET.

Answer:
d = 303.33 m
Explanation:
Given that,
Acceleration of Doc Brown is 2.52 m/s²
The initial speed of Doc Brown is 0 as it was at rest.
Final speed of Doc Brown is 39.1 m/s
We need to find the distance between he and Marty. Let the distance is d. Using equation of motion as follows :
So, the distance between he and Marty is 303.33 m.
R=√20²+40²+2.20.40 cos 50
R=55 N
R/sin β = F/sin α
55/sin 50 = 40/sin α
α = 33°
Answer:
Explanation:
a) series resistors carry the same current
A = V/Re = 6/(16 + 6) = 0.2727272... ≈ 27 mA
b) V = V₀(R/Re) = 6(16/(16 + 6)) = 4.363636 ≈ 4.4 V
c) V = V₀(R/Re) = 6(6/(16 + 6)) = 1.636363 ≈ 1.6 V
or V = 6 - 4.4 = 1.6 V
Answer: A satellite with a mass of 110 kg and a kinetic energy of 3.08×10^9 J must be moving at a speed of 7483 m/s.
Explanation: To find the answer we need to know about the kinetic energy of a body.
<h3>
How to solve the problem the equation of kinetic energy?</h3>
- We have the expression for kinetic energy of a body as,
- We have to find the speed of the satellite,
Thus, we can conclude that, the velocity of the satellite will be 7438m/s.
