Answer:
the higher the value of the coefficient of friction the MORE the resistance to sliding .
Answer:
true
Explanation:
Initially it requires more force to break the interlock between the irregularities of two surfaces. But once the block is in motion, it takes time to interlock between the irregularities of two surfaces. Also, the body gains the inertia of motion.
Answer: t = 1.6s
Explanation: Use Fab 5 equation to solve for t (d is irrelevant so use equation without d)
vi = 16m/s, a = -10m/s^2, vf = 0m/s, t = ?
(Assume up is positive so acceleration is negative!!!)
a = vf - vi / t
-10 = 0 - 16 / t
-10t = -16
t = 1.6s
Hope this helps! :)
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
