Two cars are facing each other from opposite ends of a 500m long road. Car A begins travelling at a constant speed of 20m/s. At

the same moment, Car B begins travelling toward Car A at a constant speed of 16m/s. How far will Car A move before colliding with Car B?

Answer:

Correct answer:  D₁ = 277.78 m  

Explanation:

Before colliding  with car B, car A will cross the next distance:

D₁ = V₁ t  

Before colliding  with car A, car B will cross the next distance:

D₂ = V₂ t

The total distance is:

D = D₁ + D₂  => D = V₁ t + V₂ t  => D = t (V₁ + V₂) => t = D / (V₁ + V₂)

t = 500 / (20 + 16) = 500 / 36 = 13.89 seconds

D₁ =  V₁ t  = 20 · 13.89 = 277.78 m

D₁ =  277.78 m

Which of the following options is correct and why?
Dimas [21]

Answer:

Option (e) = The charge can be located anywhere since flux does not depend on the position of the charge as long as it is inside the sphere.

Explanation:

So, we are given the following set of infomation in the question given above;

=> "spherical Gaussian surface of radius R centered at the origin."

=> " A charge Q is placed inside the sphere."

So, the question is that if we are to maximize the magnitude of the flux of the electric field through the Gaussian surface, the charge should be located where?

The CORRECT option (e) that is " The charge can be located anywhere since flux does not depend on the position of the charge as long as it is inside the sphere." Is correct because of the reason given below;

REASON: because the charge is "covered" and the position is unknown, the flux will continue to be constant.

Also, the Equation that defines Gauss' law does not specify the position that the charge needs to be located, therefore it can be anywhere.

A runner has an initial velocity of 4 meters per second. After 20 seconds, the runner's velocity is 6 meters per second. Which i
jasenka [17]

Answer:

B. 0.1 meters/second/second in the same direction of travel.

Explanation:

Acceleration is the rate of change of velocity. Acceleration is a vector quantity.

a=Δv/Δt

=(v₂-v₁)/(t₂-t₁)

v₁=4 m/s

v₂=6 m/s

t₁=0 s

t₂=20 s

a=(6m/s-4m/s)/(20s-0)

= 0.1 m/s² in the same direction of travel.

Therefore acceleration =0.1 meters/second/second in the same direction of travel.

Anarel [89]
I just figured this out now.
First you would use the formula
Ephoton= hc/λ and substitute in the value's of plank's constant, the speed of light in a vaccum and the wavelength which will give you the energy in joules. Then you go to the reference table and solve for the energy used between the different levels for Mercury making sure to convert electron volts to jules. In the end the correct answer should be energy level D.

Suppose you have a toy car made of copper. The car has the mass of 224 grams. What is the volume of your toy car?
melamori03 [73]

Answer:

Volume = 25 cm^3

Explanation:

We know that the density of any kind of substance or material is equal to:

density= mass/volume\\\\densitycopper= 8.96gram/cm^3\\mass=224grams\\volume=mass/density\\\\volume=224/8.96 = 25 cm^3
