Answer:
<em>0.45 N</em>
Explanation:
<em>Let Recall that,</em>
<em> The power formula is: </em>
<em> P = E²/R </em>
Let A = the magnetic field
<em>Let L = length of wire = 9.00cm = 0.09 m </em>
let R = resistance of wire = 0.320 Ω
let v = velocity of the wire = 4 m/s
<em>Let E = across the wire voltage </em>
Let P = the power of the wire = 4.3 W
To Solve for E:
<em>The formula of E = √PR </em>
The Voltage from a magnetic field is given as,
E = vAL
We therefore Use E = E
√PR = vAL
to solve for A,
A= √PR/vL
BA= √4.3(0.32)/(4)(.09) -=0.173
A = 0.173 wA/m²
Let F be the pulling force
Let I be the current in the wire
P = I²R
<em>I = √P/R </em>
F = IAL
F = √P/RAL
F = √4.3/.32(0.173)(.09)
<em>F = 0.45N</em>
They are both Simple mechanics

Answer:
108.18 m/s2
Explanation:
1 atm = 101325 Pa
r = 7.41 mm = 0.00741m
Since the pressure is increased by a factor of 2.55, the new inner pressure inside the system would be
P = 101325 * 2.55 = 258378.75 Pa
This pressure exerts a force on the metal cylinder, knowing the radius, we can calculate the cross-section area:
Then the force exerted:
Finally we can calculate the initial acceleration in accordance with Newton's 2nd law of motion:
