Answer:0.0144 tesla
Explanation:
Magnetic field strength is the same as Magnetomotive force
B= I/2πr
B=magnetic field strength
I=current
r=radius=0.15/2=0.75m
Area=πr2= 1.77m2
torqueT= NIABsin theta
B= T/NIABsin theta
B=0.135/1 * 5.3 * 1.77 *sin90
B=0.0144 tesla
To answer this question, it helps enormously if you know
the formula for momentum:
Momentum = (mass) x (speed) .
Looking at the formula, you can see that momentum is directly
proportional to speed. So if speed doubles, so does momentum.
If the car's momentum is 20,000 kg-m/s now, then after its speed
doubles, its momentum has also doubled, to 40,000 kg-m/s.
Answer:
The process by which wind removes surface materials is called deflation.
The source and the observer are moving towards each other. The observer is moving toward the source. The source is moving away from the observer
Answer:
Vo = 4.5 [m/s]
Explanation:
In order to solve this problem, we must use the following equation of kinematics.
where:
Vf = final velocity = 12 [m/s]
Vo = initial velocity [m/s]
a = acceleration = 1.5 [m/s²]
t = time = 5 [s]
Now replacing:
![12=v_{o}+1.5*5\\v_{o}=12- (7.5)\\v_{o}= 4.5[m/s]](https://tex.z-dn.net/?f=12%3Dv_%7Bo%7D%2B1.5%2A5%5C%5Cv_%7Bo%7D%3D12-%20%287.5%29%5C%5Cv_%7Bo%7D%3D%204.5%5Bm%2Fs%5D)
