Answer: diode

Explanation: A diode is an electronic device that has the ability to work in 1 direction of electric current.

At forward bias ( when the positive terminal of the diode is connected to the positive terminal of the source and negative terminal to the negative of the source) the diode allows current to flow thus acting as a close switch.

At reverse bias ( when the positive terminal of the diode is connected to the negative terminal of the source and the negative terminal of the diode to the positive terminal of the source) the diode stops question from flowing thus acting like an open circuit or an open switch

Which object will have the most potential energy?
Svetradugi [14.3K]

Answer:  the most potential energy ==  5 kg book, 2 m from the ground= 98 Joules

Explanation:

potential energy = m g h

m = mass

g = acceleration due gravity  = 9.8 m/s²

h = distance above  ground

1.  Pe₁ = 1 kg x 2 m x g  = 2 g

2. Pe₂ = 5 kg x 2 m x g = 10 g = 10 kg m x 9,8 m/s² = 98 Joules

3. Pe₃ = 1 kg x 0,5 m x g = 0,5 g

4. Pe₄ = 5 kg x 0.5 m x g = 2,5 g  

10 > 2,5 > 2 >0,5

Objects 1 and 2 attract each other with a electrostatic force of 72.0 units. If the charge of object 1 is doubled AND the charge
lbvjy [14]

Answer:

432 units

Explanation:

Let the charges be q and Q separated by a distance r. The electrostatic force , F = kqQ/r² = 72 units. If q = 2q and Q = 3Q, then the new electrostatic force is

F = k × 2q × 3Q/r² = 6kqQ/r² = 6 × 72 = 432 units

Elsa runs 100m. She takes 20s to run this distance. What is Elsa's average speed?
Ne4ueva [31]

Answer:

Average speed = 5 m/s

Explanation:

Given the following data;

Distance = 100m

Time = 20 secs

To find the average speed;

Speed = distance/time

Substituting into the formula, we have;

Speed = 100/20

Speed = 5m/s

Therefore, Elsa's average speed is 5 meters per seconds.

A car travels in a flat circle of radius R. At a certain instant the velocity of the car is 24 m/s west and the total accelerati
lisov135 [29]

Answer with Explanation:

We are given that

Velocity,v=24 m/s west

Acceleration,a=2.5m/s^2

\theta=53^{\circ}(N of W)

Horizontal component of acceleration=Tangential acceleration

Tangential acceleration,a_x=acos\theta=2.5cos53=1.505 m/s^2

Radial acceleration=Vertical acceleration=a_y=asin\theta

a_y=2.5sin53=1.998 m/s^2

Radial acceleration,a_y=\frac{v^2}{R}

1.998=\frac{(24)^2}{R}

R=\frac{(24)^2}{1.998}

R=288.29 m

Time,t=\frac{2\pi R}{velocity}

t=\frac{2\pi(288.29)}{24}

t=75.47 s
