A point charge of 5. 0 × 10–7 c moves to the right at 2. 6 × 105 m/s in a magnetic field that is directed into the screen and has a field strength of 1. 8 × 10–2 t. What is the magnitude of the magnetic force acting on the charge?.

Answer:

C. It triples in magnitude (PLATO)

When the induced electric current, if the number of loops is increased from one to three, it triples in magnitude. The correct option is C.

A shifting magnetic field causes an induced current. An induced emf accompanies the induced current. Without a battery in the circuit, a current can be generated.

The induced emf can be described using Faraday's law of induction. Induction is the method of creating current in a conductor by exposing the conductor to a shifting magnetic field.

Since there is no actual physical link between the conductor and the magnet, this phenomenon is known as induction. The magnetic field is said to induce the current in the conductor.

Therefore, the correct option is C. It triples in magnitude.

Answer:

True

Explanation:

A scientific theory is a phenomenon that describes the explanation of a given fact or observation. Using the scientific method, a hypothesis/tentative explanation is given, which is tested via an experiment. If the hypothesis is tested to be true by substantial evidence, it becomes a SCIENTIFIC THEORY, which is an accepted explanation for a factual occurrence.

Hence, it can be said that a SCIENTIFIC THEORY is a hypothesis found to be true and backed up by repeatable experiments. It should be noted that a theory is not a fact, however, a scientific theory explains or interprets a scientific fact.

Therefore, the statement that a scientific theory is a summary of fact and states a predictable relationship or observation under specific conditions is TRUE.

Explanation:

First we need to find the net horizontal or applied force of the mass :

     Fa = F1 + F2

Because they oppose each other it is negative :

     Fa = F1 - F2

     Fa = 9N - 3N

     Fa = 6N

Now we can use F = mass x acceleration to find the acceleration :

     6 N = 2kg x acceleration

     6- 2 = acceleration

This question involves the concepts of the time period, orbital radius, and gravitational constant.

The theoretical period of the moon is "658 hr".

The theoretical time period of the moon around the earth can be found using the following formula:

\(\frac{T^2}{R^3}=\frac{4\pi^2}{GM}\)

where,

T = Time Period of Moon = ?

R = Orbital Radius = 3.84 x 10⁸ m

G = Gravitational Constant = 6.67 x 10⁻¹¹ N.m²/kg²

M = Mass of Earth = 5.97 x 10²⁴ kg

Therefore,

\(\frac{T^2}{(3.84\ x\ 10^8\ m)^3}=\frac{4\pi^2}{(6.67\ x\ 10^{-11}\ N.m^2/kg^2)(5.97\ x\ 10^{24}\ kg)}\\\\T^2=(9.91\ x\ 10^{-14}\ s^2/m^3)(56.62\ x\ 10^{24}\ m^3)\\\\T=\sqrt{561.34\ x\ 10^{10}\ s^2}\)

Through space, a spacecraft is moving. It picks up speed abruptly. How would you characterize the spacecraft's kinetic energy? As the speed rises, the kinetic energy does too.

An object's kinetic energy refers to the energy it has as a result of motion. Applying force is necessary if we wish to accelerate an object. We have to put forth work to apply a force. After the job is finished, the object will be travelling at a new, constant speed because energy has indeed been transferred to it.

Velocity is the force that propels motion, which can be seen in the movement of a particle, an object, or a group of particles. A person walking, a baseball being thrown, a piece of food falling from the a tabletop, as well as a charged particle inside an electric field all are instances of objects in motion that use kinetic energy.

Answer:

a)   τ₁ = 660 N m,  b)  τ’= 686 N m,  c)    F = 623.6 N

Explanation:

a) For this exercise let's use the concepts of torque and rotational balance.

For this we set a reference system at the base and assuming that the counterclockwise rotations are positive

where the force F = 600 N, the distance to the axis is x = 1.1 m, the mass of the system m = 70g and the weight is placed at the point of the center of  gravity x_{cm} = -1.0 m

The torque at the front is

          τ₁ = F x

          τ₁ = 600 1.1

          τ₁ = 660 N m

b) let's write the rotational equilibrium condition

           ∑ τ = 0

           τ'- W x_{cm} = 0

           τ ’= mg x_{cm}

            τ’= 70 9.8 1.0

            τ’= 686 N m

c) the greatest force Matt can apply

           τ’= F x

           F = τ’/ x

           F = 686 / 1.1

           F = 623.6 N

Taking into account the definition of speed, the average speed of the fastest man in the world is 16.35 miles per hour.

Speed can be defined as the amount of space traveled per unit of time with which a body moves.

That is, the speed is associated with the change of position of an object in space within a certain amount of time and can be calculated using the expression:

speed= space traveled÷ time

In this case:

Replacing these values ​​in the definition of speed:

speed=0.0621371 miles÷ 0.0038 h

Solving:

Speed= 16.35 miles per hour

In summary, the average speed of the fastest man in the world is 16.35 miles per hour.

By considering the principles of reflection of light particles, we can determine the angle at which the cue ball will approach the other ball after double banking.

To determine the angle at which the cue ball will approach the other ball after double banking, we need to consider the principles of reflection of light particles. Just like a pool ball bounces off the edges of a pool table, a light particle bounces off a mirror at the same angle it approaches the mirror. In this case, the first bank acts as the first mirror, and the second bank acts as the second mirror. Using the given dimensions, we can calculate that the distance from the first bank to the target ball is 4' - 1' = 3'. Since we need to hit the first bank at a point 3 1/3 feet from the cue ball, the angle of incidence (angle between the cue ball's path and the first bank) can be calculated as arctan(3 1/3 / 3) = 55.4 degrees.

The primary effect of increasing the surface tension of the liquid is to increase the capillary force. Capillary forces arise due to the combined effects of adhesion and cohesion

When the surface tension of the liquid increases, the capillary rise will increase. It is because the increase in surface tension leads to an increase in the force that pulls the liquid upwards in a tube. is as follows;If you place a capillary tube in a beaker filled with water, the water surface inside the tube rises slightly higher than the level outside the tube.

This rise in water level is called capillary rise. The capillary rise is caused by the attraction between the molecules of the water and the molecules of the glass tube.This attraction is called capillary force or capillary action. The capillary force is due to the combined effect of adhesive and cohesive forces. The adhesive force is the attraction between the molecules of the liquid and the molecules of the solid surface, while the cohesive force is the attraction between the molecules of the liquid.

Binomial distribution refers to a probability distribution of discrete random variables. The binomial probability distribution depends on the number of experiments that were conducted within a fixed time period.

Shinedown Classical’s singer learned from long experience that the probability that a mic accident will occur while he is singing a song is 0.40. During one hour, the singer sings 5 songs.

Find the graph of the binomial probability distribution that shows the probabilities that 0,1,2,3,4, or all 5 songs experiencing mic outages.Binomial distribution formula .

The probability of getting r successes from n trials is given by;$$\text{P}(r) = \binom{n}{r}p^r(1-p)^{n-r}$$where n = number of trials, r = number of successes, p = probability of success, and 1 - p = probability of failure. In this case, q = 0.40, p = 1 - q = 0.60, and n = 5. Hence, the probability of having r mic outages while the singer sings 5 songs is given by:$$\text{P}(r) = \binom{5}{r}(0.60)^r(0.40)^{5-r}

We can then determine the probability of having 0, 1, 2, 3, 4, and 5 mic outages as follows;For r = 0, P(0) = (5 choose 0) × (0.60)⁰ × (0.40)⁵ = 0.01024For r = 1, P(1) = (5 choose 1) × (0.60)¹ × (0.40)⁴ = 0.07680For r = 2, P(2) = (5 choose 2) × (0.60)² × (0.40)³ = 0.23040For r = 3, P(3) = (5 choose 3) × (0.60)³ × (0.40)² = 0.34560For r = 4, P(4) = (5 choose 4) × (0.60)⁴ × (0.40)¹ = 0.25920For r = 5, P(5) = (5 choose 5) × (0.60)⁵ × (0.40)⁰ = 0.07776These values can then be used to plot a graph of the binomial probability distribution.
