That particular highly complex scalar quantity is called the wave's "speed".
Answer: 5.71kg and 10.33N
Explanation:
Recall,
Weight =mass × g
Where w = 56.0 N , g = 9.8 m/s2
56= m × 9.8
M = 56/9.8
M = 5.71 kg
At the surface of the moon, the mass still remains 5.71kg because it is a fundamental quantity it does not change irrespective of position.
Weight at the moon surface will change as a result of change in gravity. Hence, weight = mg
Where g=1.81m/s2, m= 5.71
W = 5.71×1.81
W = 10.33N
Which excerpt are you talking about?
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
