The answer to your question is "eelectromagnet". Electromagnets only produce a magnetic field when they have an electric current nearby, and are some of the more powerful magnets on Earth, running things such as MRI machines, and junkyard manet cranes. They also are part of why electric motors spin.
Answer:
the answer is a)5.82s
Explanation:
Hello!
The first thing we must understand to solve this exercise is that a capacitor has the following characteristic function

where
Vo=initial voltage
V=voltage in an instant of time
t=time
R=resistance=4000Ω
C=capacitance=2.1-mF=0.0021F
we must consider that the final voltage is half of the initial voltage so we deduce the following equation
V=Vo/2
Now we replace in the initial equation, and start an algebraic process to find t

finally with the equation ready, we use the resistance and capacitance values to find the time value

the answer is a)5.82s
Because it is not dominant? that is what im guessing
Answer:
Latent heat, along with birds, ride those rising columns of air. This brings up a third and the ultimate mechanism by which the Earth's heat escapes into space, which is electromagnetic radiation. Every object, including the Earth's surface, absorbs and radiates heat electromagnetically

I LITERALLY JUST COPIED AND PASTED THIS FROM GOOGLE..i dont understand anything from it since im not on this topic but hope this help a little....i got it from google ..not my own work
Apply Newton's second law to the person's motion:
F = ma
F = net force, m = mass, a = acceleration
Given values:
m = 50.8kg, a = 3.50m/s²
Plug in and solve for F:
F = 50.8(3.50)
F = 178N
