Change in volume = mass x coefficient of linear expansion x change in temperature
.002 x .0001802 x 30 = .000010812
initial volume + change in volume = Final volume
.002 + .000010812 = .002010812 m cubed
Answer:
(a) The magnetic energy density in the field is 6.366 J/m³
(b) The energy stored in the magnetic field within the solenoid is 5 kJ
Explanation:
magnitude of magnetic field inside solenoid, B = 4 T
inner diameter of solenoid, d = 6.2 cm
inner radius of the solenoid, r = 3.1 cm = 0.031 m
length of solenoid, L = 26 cm = 0.26 m
(a) The magnetic energy density in the field is given by;
(b) The energy stored in the magnetic field within the solenoid
Answer:
20kph
Explanation:
Since she travels 100kpm in 5 hours and 100 divided by 5 is 20 she would travel 20km in one hour
Answer:
Vf = 0.0108 m³
Explanation:
Assuming there is no change in internal energy, we can calculate the changed volume by the following formula:
where,
W = Work = Energy Supplied = 1000 J
P = Pressure = 101325 Pa
Vf = Final Volume = ?
Vi = Initial Volume = 0.001 m³
Therefore,
<u>Vf = 0.0108 m³</u>
