The induced electromotive force in the bar is 0.206 volt.
<h3>What is induced electromotive force?</h3>
It is the creation of a potential difference in a coil as a result of variations in the magnetic flux flowing through it. To put it another way, it is said that electromotive force, or EMF, is induced when the flux connecting with a conductor or coil changes.
Given parameters:
Length of the bar: l = 0.12 meter
Speed of the bar: v = 29.6 m/s.
Magnetic field: B = 58 mT = 58 × 10⁻³ T.
Hence, the induced electromotive force in the bar: ε = lvB
= 0.12 × 29.6 × 58 × 10⁻³ Volt
=0.206 volt.
Hence, the induced electromotive force in the bar be 0.206 volt.

Oh wait if what I said is wrong actually and now of what I'm telling you right now is really actually the answer... so when 108 grams of water at a temperature of 22.5c is mixed with 65.1 grams of water at an unknown temperature,the final temperature of the resulting mixture of 47.9c.
Answer:
Explanation:
lower the temperature -the higher the temp the more energy the molecules absorb. The more energy they have the more they move

Answer:
a)15077 W
b)20.2185 horse power
Explanation:
P=F*V
F=ma
a=Vf-VS/t
Vf=28m/s
t=5.2
a=28/5.2
a=5.384 m/s²
F=100kg*5.384m/s²
F=538.4 N
P=F*V
P=538.4N*28m/s
P=15077 W=20.2185 horse power
1W=0.00134 Horse power
