Consider a superconducting MRI magnet for which the magnet field decreases from 8.0 T to nearly 0 in 20 s
Answer:
0.152 mV
Explanation:
Change in magnetic field, dB=8-0=8 T
Time interval, dt=20 s
Diameter of ring= 2.2cm hence radius is 1.1 cm equivalent to 0.011
where n is the number of terms and for this question n=1 and A is area which is given by 
hence
and substituting the values
Therefore, induced emf is 0.152 mV
The bearing shows the angle from north to the line (c), you want to see the angle inside the triangle so that will be 90-[bearing].
<span>a=42 (42 mph wind blowing north) </span>
<span>A= 90-74.9 </span>
<span>A= 15.1 degrees </span>
<span>Ground speed is the speed the plane is going including the wind. </span>
<span>ground speed = c </span>
<span>Airspeed = b </span>
<span>You have the angle, and you have the "Opposite" and want to find the "Hypotenuse". </span>
<span>SOH CAH TOA </span>
<span>Sin x = Opp/Hypot </span>
<span>Sin(15.1) = 42/c </span>
<span>c = 42/Sin(15.1) </span>
<span>c = 161.53 </span>
<span>Ground speed of the plane is 161.53 mph </span>
<span>Airspeed = b </span>
<span>Tan x = Opp/Adj </span>
<span>Tan (15.1) = 42/b </span>
<span>b = 42/Tan(15.1) </span>
<span>b = 161.53 </span>
<span>Airspeed = 161.53 mph </span>
<span>(so the answer is ground speed of 161.53mph)</span>
Answer:
<h2>1960 J</h2>
Explanation:
The potential energy of a body can be found by using the formula
PE = mgh
where
m is the mass
h is the height
g is the acceleration due to gravity which is 9.8 m/s²
PE = 10 × 9.8 × 20
We have the final answer as
<h3>1960 J</h3>
Hope this helps you
i think it D but am not real sure pls don't hate me
Cardio refers to your heart. if you're a strong cardio person, you probably have a ton of stamina and have a fairly slim build. Where as strenght-training more so concentrates of building muscles by lifting and such. <span />
