Answer:
Explanation:
From the information given:
The motional emf can be computed by using the formula:
E = 0.72 volts
According to the question, suppose the wire segment was parallel, there will no be any emf induced since the magnetic field is present along the y-axis.
As such, for any motional emf should be induced, the magnetic field, length, and velocity are required to be perpendicular to one another .
Then the motional emf will be:
E = 0 (zero)
Answer:
2.30 atm
Explanation:
Using Boyle's law :-
This can be written as:-
Given ,
For Bulb 1
Pressure = 7.25 atm
Volume = 51.0 mL
For Bulb 2
Pressure = 1.18 atm
Volume = 250 mL
For Bulb 3
Volume = 45.0 mL
Pressure = 5.96 atm
Given that the volume of the tubing = 47.0 mL
Volume of the whole system = Sum of the volume of the three bulbs + Volume of the tubing
Also, Total volume, V = 51.0 + 250 + 45.0 +47.0 mL = 393 mL
Using above equation as:
We get, Total pressure, P = 2.30 atm
The work done in lifting the hamburger is equal to the increase in gravitational potential energy of the hamburger, given by
where
m=0.1 kg is the mass of the hamburger
is the gravitational acceleration
is the increase in height of the hamburger
Substituting numbers into the equation, we find
So, the correct answer is
(3) 0.3 J
