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
The last one - biological attributes
Answer:
<em>Radiation is energy that comes from a source and travels through space and may be able to penetrate various materials. Light, radio, and microwaves are types of radiation that are called nonionizing.</em>
Explanation:
Answer:
714.286 kg
General Formulas and Concepts:
Physics 1
- Fg = mg
Fg is gravitational force in Newtons
m is the mass of the object in kilograms
g is the gravitational acceleration of Earth: 9.8 m/s^2
Step-by-step explanation:
Step 1: Define
7000 N = Fg
g = 9.8 m/s^2
Step 2: Solve for m
1. Substitute: 7000 N = m(9.8 m/s^2)
2. Isolate m: 714.286 kg = m
