Answer:

Explanation:

Magnitisim is caused by a moving electric field, and electricity can be caused by a moving magnetic feild.

i would like to breefly explain how light is a product of these two fields.

Say you have an electricly charged particle. lets prettend it has a +electric field. Lets shake it up and down in a periodic way. So now the electric field is moving perpendicular to the motion of the particle. But the electric field has to turn into a magnetic field becuase its moving. and it does. but the the same happins with the magnetic feild becuase its moving. and it goes back and forth and gives rise to light

Electricity and magnetism are essentially two aspects of the same thing, because a changing electric field creates a magnetic field, and a changing magnetic field creates an electric field

A particle is moving along a projectile path where the initial height is 160 feet with an initial speed of 144 feet per second.

Leviafan [203]

Assuming Earth's gravity, the formula for the flight of the particle is:

s(t) = -16t^2 + vt + s = -16t^2 + 144t + 160. 

This has a maximum when t = -b/(2a) = -144/[2(-16)] = -144/(-32) = 9/2. 

Therefore, the maximum height is s(9/2) = -16(9/2)^2 + 144(9/2) + 160 = 484 feet.

Please help me, this is a physics test.

Answer:

a = 2 [m/s²]

Explanation:

To be able to solve this problem we must make it clear that the starting point when the time is equal to zero, the velocity is 5 [m/s] and when three seconds have passed the velocity is 11 [m/s], this point is the final point or the final velocity.

We can use the following equation.

$v_{f}=v_{o}+a*t\\$

where:

Vf = final velocity = 11 [m/s]

Vo = initial velocity = 5 [m/s]

a = acceleration [m/s²]

t = time = 3 [s]

$11 = 5 + a*3\\6=3*a\\a= 2[m/s^{2} ]$

What should a scientist do if the results and data do not support his/her hypothesis?

german

Answer: If it does not support the hypothesis, you may choose to change the hypothesis or write a new one based on what was learned during the experiment.

Hypothesize a new answer to the question and a new way to test it.
