A person who unintentionally grabs the terminals of a 14-kV power supply while holding body resistance between his palms.

(A) What is the current flowing through the person's body if the power supply's internal resistance is?

(b) Where does his body's power go when it is dispersed?

(c) If the power supply's internal resistance is to be increased in order to make it safer, what internal resistance should it have for the maximum current in the aforementioned scenario to be 1.00 mA or less?

employing ohm's law

a) The equation V = IR, where V is the voltage in volts, I is the current in amperes, and R is the resistance in ohms

R = V / I = 1.50 V/ ( 2.05 /1000) A = 731.71 ohms

b) E = IR + Ir = (731.71 0.0036) Power = IV = v = = = 0.1107 W

Ohm's regulation states that the cutting-edge through a conductor between two factors is without delay proportional to the voltage across the two factors. Introducing the steady of proportionality, the resistance, one arrives at the usual mathematical equation that describes this relationship:

The regulation became named after the German physicist Georg Ohm, who, in a treatise posted in 1827, described measurements of applied voltage and current thru easy electrical circuits containing various lengths of wire.

The one who waits for a shorter time wins. Neha leaves her pendulum from point L and Suhani leaves her pendulum from point P.Neha wins as her bob comes back faster. Therefore, option A is correct.

A weight suspended from a pivot such that it can freely swing is called a pendulum. Gravity's restoring force will cause a pendulum to accelerate back toward its equilibrium position if it is sideways moved from its resting, equilibrium position.

An object that is suspended from a fixed location by a string or rod and can move freely due to gravity and momentum. frequently used to control electronics like clocks. Simple pendulum: A back-and-forth swinging pendulum. A circularly swinging pendulum is referred to as a spherical pendulum.

The force of gravity acting on the swing causes it to move freely back and forth after being raised and released. The swing keeps returning.

Answer:

Newton's law of gravitation states that every object in this universe attracts every other object with a force called gravity,

when the distance between the two object is increased the gravitational force decreases by its square,

and when the mass an object increases the gravitational force also increases,

therefore, gravitational force is directly proportional to the mass of the two objects and is square inversely proportional to distance between them.

What is a magnetic field?

The magnetic influence on moving electric charges, electric currents, and magnetic materials is described by a magnetic field, which is a vector field. A force perpendicular to the magnetic field and its own velocity acts on a moving charge in a magnetic field. The magnetic field of a permanent magnet pulls on ferromagnetic substances like iron and attracts or repels other magnets. A magnetic field that varies with location will also exert a force on a variety of non-magnetic materials by changing the velocity of those particles' outer electrons. Electric currents, like those utilized in electromagnets, and electric fields that change in time produce magnetic fields that surround magnetized things. Since a magnetic field's position can affect both its strength and its direction.

By using the trend line option in excel, we get

Answer:

90N

Explanation:

The total resultant force acting on the desk being pushed by Sara and Carlo is 90N

A resultant force is a singular force that will act the same effect as the forces acting on a body.

So;

  Resultant force = Force applied by Sara + Force applied by Carlo

  Resultant force  = 50N + 40N  = 90N

1. The phone is moving with a velocity of 20.77 m/s before racking into pieces

2. The time taken for the ball to come back to their hand is 0.82 s

3. The maximum height reached by the batarang is 49.03 m

4. The cliff is 1016.06 m high

5. The object is moving with a velocity of –8.6 m/s after 2 s

v² = u² + 2gh

v² = 0² + (2 × 9.8 × 22)

v² = 431.2

Take the square root of both side

v = √431.2

v = 20.77 m/s

We'll begin obtaining the time taken to reach the maximum height. This is illustrated below:

v = u – gt (since the ball is going against gravity)

0 = 4 – (9.8 × t)

0 = 4 – 9.8t

Collect like terms

0 – 4 = –9.8t

–4 = –9.8t

Divide both side by –9.8

t = –4 / –9.8

t = 0.41 s

Finally, we shall determine the time for the entire trip

T = 2t

T = 2 × 0.41

T = 0.82 s

v² = u² – 2gh (since the ball is going against gravity)

0² = 31² – (2 × 9.8 × h)

0 = 961 – 19.6h

Collect like terms

0 – 961 = –19.6h

–961 = –19.6h

Divide both side by –19.6

h = –961 / –19.6

h = 49.03 m

h = ½gt²

h = ½ × 9.8 × 14.4²

h = 4.9 × 207.36

h = 1016.06 m

v = u – gt (since the ball is going against gravity)

v = 11 – (9.8 × 2)

v = 11 – 19.6

v = –8.6 m/s

Answer: B. 12 N

Explanation:

Static Equilibrium

Static equilibrium occurs when an object is at rest, i.e., neither rotating nor translating.

In the static rotational equilibrium, the total torque is zero with respect to any rotational axis.

The torque applied by a force F perpendicular to a displacement X with respect to a reference rotating point is:

T = F*X

Considering the pivot as the rotating point, there are 3 forces producing torque. Let's consider counterclockwise torques as positive, thus:

30N * 40 cm - 60 N * 30 cm + F (30 cm + 20 cm) = 0

Operating:

1200 N.cm - 1800 N.cm + F(50 cm) = 0

- 600 N.cm + F(50 cm) = 0

Solving for F:

F = 600/50

F = 12 N

The acceleration of a car that starts from rest and accelerates to a speed of 30 m/s in 20 seconds is 1.5 m/s².

Acceleration is defined as the change in velocity of a body or an object with time.

Mathematically;

The acceleration of the car is calculated using the equation of motion as follows:

v = u + a * t

where;

v is the final velocity

u is the initial velocity

t is the time taken

a is the acceleration

From the dat provided: v = 30 m/s, t = 20 s, u = O m/s

a = v - u/t

a = 30 - 0/20

a = 1.5 m/s²

Therefore, the acceleration of the car that starts from rest and accelerates to a speed of 30 m/s in 20 seconds, is 1.5 m/s².

Hi! It would be A. Plane mirrors produce only virtual images,and concave mirrors produce real and virtual images.

Plane mirrors construct only virtual images, and concave mirrors make real and virtual images. Thus, this statement best corresponds concave and plane mirrors.

A virtual image exists represented as the opposite of a real image, thus an image that cannot be obtained on a screen stands produced as a virtual image. The motivation for this exists in the fact that the beams of light that form a virtual image never connect therefore a virtual picture can never be projected onto a screen. Examples: Image formed in a plane mirror, an image constructed on the front and back surfaces of a spoon, etc.

Therefore, the (A) option exists as the accurate answer.
