What personal experiences have you had with watching a substance change from one phase to another?

A ten loop coil of area 0.23 m2 is in a 0.047 T uniform magnetic field oriented so that the maximum flux goes through the coil.

andrezito [222]

Answer:

Explanation:

From the question we are told that:

Number of turns $N=10$

Area $a=0.23m^2$

Magnetic field $B=0.947T$

Generally the equation for maximum flux is mathematically given by

$\phi=NBa$

$\phi=10*0.047*0.23$

$\phi=0.1081wbi$

Therefore induced emf

$e= \frac{d\phi}{dt}$

Since

$t=0$

Therefore

$e=0$

A mover uses a ramp to push a stereo into the moving van. The ramp is 3 meters long and 1.5 meters high. What is the ima of this

densk [106]

Mechanical advantage<span> <span>is a measure of the force amplification achieved by using a tool, </span>mechanicaldevice or machine system. Ideally, the device preserves the input power and simply trades off forces against movement to obtain a desired amplification in the output force. The model for this is the law of the lever. So the ima is 3/1.5 = 2</span>
