Answer:
A) Walking would burn up more energy
B) Walking: 1,914,000 J
Running: 1,386,000 J
C) Even though running is more intense and burns energy at higher rate, it burns energy for a much shorter time than walking.
Explanation:
Watt is a unit for power that is equivalent to Joules per second (J/s). Therefore, to figure out the energy burnt up during an activity, first we need to know how long (in seconds) that activity took.
1- Running
V = 10.0 km/h
d = 5.50 km
t = 5.50/10 = 0.55 h = 0.55(h) *60 (min/h) *60(s/min) = 1,980 s
2- Walking
V = 3.0 km/h
d = 5.50 km
t = 5.50/ = 1.83333 h = 1.83333(h) *60 (min/h) *60(s/min) = 6,600 s

SONAR stands for "sound navigation and ranging,” and it is used to map and explore the ocean floor.
Looks like B. Remember the sum is the sum of directions.
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
