<h3>Description of each part :-</h3>

Metal cap:- The part which is above the positive terminal, a cap of metal through which the positively charged electrons are passed.
Metal disc:- The part which is below the negative terminal, a disc of metal through which the negatively charged electrons are passed.
Positive terminal:- In a circuit the current flows from positive terminal to negative terminal.
These terminals are also known as cathode and anode.
Cathode is the other name for positive terminal and anode is the other name for negative terminal.

Answer:

Explanation:

Voltage, V = 1.58 V

Power, P = 1 W

1 A.h

Charge, Q = 1 A.h = 1 x 3600 A.s = 3600 C

Power x time = Voltage x charge

1 x t = 1.58 x 3600

t = 1.58 x 3600 second

t = 1.58 hours

A man is trying to push a 250 N dresser across his carpeted bedroom. He applies a force of 20 N and the carpet provides a fricti

11111nata11111 [884]

Answer:

The correct option is;

B. Subtract vectors A from C; $F_{Net}$ = 12 N

Explanation:

The given parameters are;

The weight of the dresser = 250 N

The force applied by the man = 20 N = C

The frictional force provided by the carpet = 8 N = The component of the weight resisting motion = A

Therefore, the net force tending to put the dresser in motion, $F_{Net}$ , is given as follows;

$F_{Net}$ = The force applied by the man, C - The frictional force provided by the carpet which is the component of the weight resisting motion, A

$F_{Net}$ = C - A = 20 N - 8 N = 12 N

$F_{Net}$ = 12 N

The resulting net force, $F_{Net}$ = 12 N.

The field inside a charged parallel-plate capacitor is __________.

Bess [88]

Uniform. A parallel plate capacitor is a simple arrangement of electrodes and dielectric to form a capacitor. Here two parallel conductive plates are used as electrodes with a medium or dielectric in between them. Charge separation in a parallel-plate capacitor causes an internal electric field, which is uniform.

An object experiences an acceleration of -6.8 m/s2. As a result, it accelerates from 54 m/s to a complete stop. How much dista

inessss [21]

Answer:

The distance traveled during its acceleration, d = 214.38 m

Explanation:

Given,

The object's acceleration, a = -6.8 m/s²

The initial speed of the object, u = 54 m/s

The final speed of the object, v = 0

The acceleration of the object is given by the formula,

a = (v - u) / t m/s²

∴ t = (v - u) / a

= (0 - 54) / (-6.8)

= 7.94 s

The average velocity of the object,

V = (54 + 0)/2

= 27 m/s

The displacement of the object,

d = V x t meter

= 27 x 7.94

= 214.38 m

Hence, the distance the object traveled during that acceleration is, a = 214.38 m
