Answer:

Velocidad final, V = 8 m/s

Explanation:

Dados los siguientes datos;

Velocidad inicial, u = 4 m/s

Aceleración, a = 2 m/s²

Tiempo, t = 2 segundos

Para encontrar la velocidad final (v), usaríamos la primera ecuación de movimiento;

V = u + at

Sustituyendo en la fórmula, tenemos;

V = 4 + 2*2

V = 4 + 4

Velocidad final, V = 8 m/s

Answer:

They do that by converting rotating mechanical energy into electrical power. Portable generators use an engine—typically running on gasoline, diesel, or propane, to turn an alternator which produces alternating electrical current or AC.

Answer:

The mass of the block of material is 3 x 10³⁷ g/mol

The charge of the material is  4.8 x 10⁸ C

Explanation:

Given;

number of protons of the material, P = 3 x 10²⁷

number of neutrons in the material, N = 3 x 10³⁷

number of electrons in the material, E =  3 x 10²⁷

The mass of the block of material is calculated as follows;

M = P + N

M =  3 x 10²⁷ +  3 x 10³⁷

M =  3 x 10³⁷ g/mol

The charge of the material is calculated as follows;

charge of 1 electron = 1.6 x 10⁻¹⁹ C

charge of  3 x 10²⁷ electrons =  3 x 10²⁷ electrons   x   1.6 x 10⁻¹⁹ C

                                                = 4.8 x 10⁸ C

Answer:

No, the car is decelerating  

Explanation:

No the car is decelerating if it exits a freeway and goes from 65

mph to 35 mph since the change in velocity is negative.

change in velocity = final - initial

change in velocity  = 35 - 65

change in velocity = -30mph

Since the change in velocity is negative, hence the car is decelerating. Deceleration is a negative acceleration

Answer:

0.19 and 0.45

Explanation:

edge

The first and second velocities of the car are [tex]0.25/t_1[/tex] and [tex]0.50/t_2[/tex]respectively.

The velocity of an object is defined as the product of the distance travelled in a given direction and the time required to travel that distance. The velocity is expressed mathematically as,

v = d/t

Here, d represents the travelled distance.

And t is the typical amount of time needed to go the distance.

Given,

The value of the first distance is, d1 = 0.25 m.

The value of the second distance is, d2 = 0.50 m.

Then the first velocity of the car at 0.25 m is,

[tex]v_1 = d_1/t_1\\v_1 = 0.25 / t_1[/tex]

Thus,[tex]t_1[/tex] denotes the first distance's typical time.

The second velocity of the car with three washers at the 0. 50 m mark is

[tex]v_2 = d_2/t_2\\v_2 = 0.50 /t_2[/tex]

Here, [tex]t_2[/tex] stands for the second distance's typical time.

Thus, the first and second velocities of the car are [tex]0.25/t_1[/tex] and [tex]0.50/t_2[/tex]respectively.

#SPJ2

Answer:

Ex = [tex]2 k q \frac{x}{(x^2 + z^2) ^{3/2}}[/tex] ,  E_z =0

Explanation:

To find the electric field of each charge, let's use

          E = k q / r²

where the field for a positive charge is outgoing and for a negative charge it is incoming.

Since the electric field is a vector magnitude, let's add its components at the point z

X axis

       Eₓ = E₁ₓ + E₂ₓ

       Eₓ = 2 E₁ₓ

Z axis

       E_z = E_{1z} -E_{2z}

       E_z= 0

Let's find the expression for the electric field

the distance from the charge to the test point, using the Pythagorean theorem is

      r² = (x-0) ² + (0-z) ²

      E = [tex]k \frac{q}{x^2 + z^2}[/tex]

with trigonometry we can find its components

      cos θ = E₁ₓ / E

      E₁ₓ = E cos θ

we substitute

     Eₓ = 2 E cos θ

where the cosine

    cos θ = x / r

     Ex = [tex]2 k \frac{q}{x^2 + z^2} \ \frac{x}{\sqrt{x^2 + z^2} }[/tex]

     Ex = [tex]2 k q \frac{x}{(x^2 + z^2) ^{3/2}}[/tex]

     E_z = 0

exothermic

Explanation:

negative means it's losing energy

Answer:

Explanation:

The charge of - 5C will be spread  on the outer surface of the shell . The presence of - 8C charge at the Centre will create + 8C charge on the inner surface and - 8C charge on the outer surface . The result is that the total charge on the outer surface of the shell will be - 5C + - 8C = - 13C and the inner surface will have charge of + 8C . + 8C charge will be locked to centrally situated - 8C charge and will not be neutralized by negative charge of outer surface .

Answer:

do not require a medium

Explanation:

Light waves can be regarded as electromagnetic waves and it transverse in nature, no medium material is required to pass through. Light wave can travel through vacuum and it's ray can travel in straight lines even from point source. Light convey energy in perpendicular direction to electric field as well as magnetic field.

Answer:

the answers the correct one is C

Explanation:

In radioactive decay processes, a very important concept is the half-life time, which is the time it takes for the parent nuclei to decompose into child nuclei.

expressed this mathematically is

              N = N₀ [tex]e^{- \lambda t}[/tex]

for the average life time

              N₀ / 2 = N₀  [tex]e^{- \lambda T_{1/2}[/tex]

               T =[tex]\frac{ln 2x}{ \lambda}[/tex]

Analyzing this expression, the nuclei that decay are the so-called parents and the new nuclei called children appear.

Answer:

germ cleaning

and getting up cooking grease

Explanation:

Answer:

24 N

Explanation:

Given,

Unstretched length or original length , x1 = 12cm

Stiffness constant, k = 8 N/cm

Load required to take spring to a length , x2 of 15cm

Recall the relation :

F = Ke

Where, e = extension

e = x2 - x1

e = (15 - 12) = 3

F = ke

F = 8 N/cm * 3cm

F = 24 N/cm*cm

F = 24 N

Hence, required load = 24 N

C. Greenhouse Effect

Explanation:

The greenhouse effect is caused by heat trapping pollution in the atmosphere.

Answer:

PRESSURE is a force exerted by the substance per unit area on another substance.

The key difference between water pressure and air pressure is that one is made up of water and the other is made up of air. Both air pressure and water pressure are based on and follow the same physical principals.

Explanation:

Add varying numbers of weights to M1 and measure the speed of the car.

Add varying numbers of weights to M2 and measure the speed of the cart.

In order to test the changing amount of force that is acting on the object has effect on the average speed of the object we have to change the amount of weight on the object and allows it to move to a certain point in this way we can check the effect of changing amount of weight on the speed of the object.

Answer:

[tex]f=7.5\times 10^{14}\ Hz[/tex]

Explanation:

Given that,

The wavelength of light, [tex]\lambda=400\ nm=400\times 10^{-9}\ m[/tex]

The speed of light, [tex]c=3\times 10^8\ m/s[/tex]

We need to find the frequency of light. We know that,

[tex]c=f\lambda[/tex]

Where

f is the frequency

So,

[tex]f=\dfrac{c}{\lambda}\\\\f=\dfrac{3\times 10^8}{400\times 10^{-9}}\\\\f=7.5\times 10^{14}\ Hz[/tex]

So, the frequency of light is [tex]7.5\times 10^{14}\ Hz[/tex].

Answer:

Explanation:

Quantum theory has taught us that virtually everything to do with the nature of matter in the universe is a random process. The decay of atomic nuclei is something that makes that randomness "visible" with appropriate instrumentation. As such, the rate of decay will vary over the "short" term. Consequently, it is not surprising to see a variation of a few counts in an activity measurement over a period of a few minutes.
