HELP!! AM I CORRECT?? PLS TELL ME, IF U ANSWER PROPERLY I'LL GIVE U BRAINLIEST!!

Answer:

wave length

Explanation:

Answer:

(you can use my exact words) The length and thickness would make it so that the electrons move differently than they would a shorter and thinner wire because with the wire being longer the electrons would have a longer trip and with the wire being thicker the electrons would be more spread out and move be able to move more freely

Answer:

2. 3.1415 m/s

3. 0.63m

4. 0.006 m/s^2

Explanation:

2. v=(2*pi*r))/T, put in values and solve.

3. Circumference=2*pi*radius, radius is 0.1m, plug in and solve.

4. a=(v^2)/r, (don't worry about converting to meters, since units are the same in kilometers, they will cancel out) plug in values and solve.

That's it!

Answer:

[tex]\lambda=5.70\times 10^{-7}\ m[/tex]

Explanation:

The frequency of a sodium vapor lamp, [tex]f=5.26\times 10^{14}\ Hz[/tex]

We need to find the wavelength of light. The relation between wavelength, frequency and speed of light is given by :

[tex]c=f\lambda\\\\\lambda=\dfrac{c}{f}\\\\\lambda=\dfrac{3\times 10^8}{5.26\times 10^{14}}\\\\\lambda=5.70\times 10^{-7}\ m[/tex]

So, the wavelength of light is equal to [tex]5.70\times 10^{-7}\ m[/tex].

A wagon of mass 42 kg is pushed by a student a distance of 12.2 meters, and 297 j of work was done on the wagon force did the student apply is 24.34 N.

A force is an effect that can alter an object's motion according to physics. An object with mass can change its velocity, or accelerate, as a result of a force. An obvious way to describe force is as a push or a pull. A force is a vector quantity since it has both magnitude and direction.

work = force*distance

force = work/distance

force = 297/12.2

force = 24.34 N

The required mass of the planet is 8 times the mass of the earth.

Given that,
The Escape speed at the surface of a certain planet is twice that of the earth. The planet has a radius twice of the Earth. what is its mass in unit of earth's mass is to be determined.

An object with this velocity at the earth's surface will completely escape the earth's gravitational field, even after accounting for atmospheric losses.

here,
The escape velocity of the planet = 2 Escape velocity of the earth
[tex]\sqrt{{2GM_p}/r_p} = 2\sqrt{2GM_e/r_e}[/tex]
Substitute the values and square both sides,
[tex]{{2GM_p}/2r_e} = 4*{2GM_e/r_e}\\M_p = 8M_e[/tex]

Thus, the required mass of the planet is 8 times the mass of the earth.

Answer:

B. C3H8

Chemical Formula for propane is C3H8

Answer:

B

Explanation:

v=349m/s

d=vt

d=349*3

d=1047m

WHY 349??

Because, velocity of sound increases about 0.6 m/s for every 1 degree celsius rise in temp.

Velocity of sound is about 343 m/s at 20 degrees C, so 0.6*10=6 more m/s, or 349 m/s. Kinda cool how temperature alters the speed of sound!

Answer:

Explanation:

Consider an endless sheet of uniform charge thickness per unit area [tex]\sigma[/tex]  

For a boundless sheet of charge, the electric field will be opposite to the surface. In this way, just the closures of a round and hollow Gaussian surface will add to the electric transition. For this situation, around and hollow Gaussian surface opposite to the charge sheet is utilized. The subsequent field is a large portion of that of a conductor at harmony with this surface charge thickness.  

By balance, we expect the electric field on one or the other side of a plane to be an element of x just to be guided typical to the plane and to point away from/towards the plane contingent upon whether, [tex]\sigma[/tex] is positive/negative.

According to the law;

[tex]2EA = \dfrac{q_{enc}}{\varepsilon_o}[/tex]

[tex]where; \ q_{enc} = total \ enclosed charge = \sigma A \\ \\ thus; \\ \\ 2EA = \dfrac{\sigma A}{\varepsilon_o} \\ \\ E = \dfrac{\sigma}{2 \varepsilon _o}[/tex]

Answer:

acceleration and mass are inversely proportional values

Explanation:

The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object.

Answer:

The answer is B.

Explanation:

Since they are made up of soft tissues, they decompose become they become fossils.

Answer:

I. increase the force that the engine provides.

II. decrease the mass of the car

Explanation:

Newton's Second Law of Motion states that the acceleration of a physical object is directly proportional to the net force acting on the physical object and inversely proportional to its mass.

Mathematically, it is given by the formula;

Force = mass * acceleration

[tex] Acceleration = \frac {Force}{mass} [/tex]

In this scenario, a car manufacturer wants to change its car’s design to increase the car’s acceleration. Thus, the changes the engineers should consider making to the design is to increase the force that the engine provides and decrease the mass of the car.
