Answer:

the rate of flow of electric charge past a point or region. An electric current is said to exist when there is a net flow of electric charge through a region. In electric circuits this charge is often carried by electrons moving through a wire. Aug 29 2019

An athlete produced 840 watts of power in 0.6 seconds. How much work did this individual perform during the exercise

Veseljchak [2.6K]

An athlete produced 840 watts of power in 0.6 seconds. And will produce 504 joule of work did this individual perform during the exercise.

<u>Solution:</u>

we know that power is the work done completed in a given interval of time.

Power = $\frac{work}{time}$

also, Work = Power × Time

Work = 840 × 0.6 = 504 joule

What is Power?

The quantity of work that can be accomplished in a certain amount of time is measured by power.
Power is expressed in joules per second (J/s) this is because work is denoted by the symbol J and time by the symbol s.
This is the watt, which is also known as the power unit in SI (W). One joule of labor per second is equal to one watt.
The number of watts that a device uses is indicated on labels for lightbulbs and other small appliances like microwaves.
A force must be applied in order for work to be completed, and there must also be motion or displacement in the force's direction.
The amount of force multiplied by the distance moved in the force's direction is known as the work done by a force acting on an item. Work has no direction and only magnitude. Work is a scalar quantity as a result.

A proton enters a uniform magnetic field of strength 1 T at 300 m/s. The magnetic field is oriented perpendicular to the proton’

scZoUnD [109]

A charged particle moving in a magnetic field experiences a force equal to:

$\vec{F}=q\vec{v}\times \vec{B}$

Thus, the magnitude of the force that the proton experiences is given by:

$F=qvBsin\theta$

The magnetic field is perpendicular to the proton's velocity, therefore, we have $\theta=90^\circ$ . Replacing the given values, we obtain:

$F=1.6*10^{-19}C(300\frac{m}{s})(1T)sin(90^\circ)\\F=4.8*10^{-17}N$

Why does a Ray of light passing through a glass slab not shown dispersion?

Hatshy [7]

Answer:

After refraction at two parallel faces of a glass slab, a ray of light emerges in a direction parallel to the direction of incidence of white light on the slab. As rays of all colours emerge in the same direction (of incidence of white light), hence there is no dispersion, but only lateral displacement.

Which type of reasoning relies on collection of evidence to make a generalization

padilas [110]

Answer:

Explanation:

I'm pretty sure the answer would be deductive reasoning. Deductive reasoning relies on making logical premises and basing a conclusion around those premises. It does not rely on making inferences and then assuming those inferences to be true.
