Answer: *360 mph*
Explanation:
I am pretty sure that it is 360 mph
3 times 120 = 360
<u>a).</u>
Kenny's potential energy at the top becomes kinetic energy at the bottom.
(M G H) = 1/2 (M V²)
Divide each side by 'M': G H = 1/2 V²
Multiply each side by 2: 2 G H = V²
Take the square root of each side: V = √(G H)
= √(9.8 x 3.2) = <em><u>5.6 m/s .</u></em>
<u>b).</u>
Notice in the solution for a). that each side of the equation was divided
by 'M'. The answer didn't depend on Kenny's mass, and it doesn't depend
on Cartman's mass either. Cartman and Kenny are both moving at the
same speed when they reach the bottom.
<u>c).</u>
Notice in the solution for a). that each side of the equation was divided
by 'M'. The answer didn't depend on Kenny's mass. It didn't depend on
Cartman's mass either, and it doesn't depend on Kyle's mass either, either.
Each of them is moving at the same speed when he reaches the bottom.
The same also applies to girls as well, too.
The first figure matches the description
Answer:
1) A time-varying magnetic field will produce an electric field.
4) A time-varying electric field will produce a magnetic field.
Explanation:
1) A time-varying magnetic field will produce an electric field.
TRUE
time varying magnetic field will produce electric field which is given as
2) Time-varying electric and magnetic fields can propagate through space only if there is no matter in their path.
FALSE
Time varying electric field and magnetic field will induce each other and it can travel through any medium as well as it can travel without any medium also
3) Electric and magnetic fields can be treated independently only if they vary in time.
FALSE
electric field can be due to stationary charge and magnetic field due to current carrying elements so it is not compulsory to have time varying
4) A time-varying electric field will produce a magnetic field.
TRUE
Time varying electric field will produce magnetic field given as
