Momentum has both direction and magnitude.
It is a vector quantity.
Its formula is = Mass * Velocity, Mass you know is associated with size and velocity of course is associated with direction.
C. direction and magnitude
Gravitational field strength (GFS) on earth =10 N/kg
Weight = GFS x mass
W = 10 x 7
W = 70N
70N = 15.74 pounds
Answer:
Yes, a body with a certain velocity can have an opposite acceleration, the acceleration would then be negative, since it is opposite to the direction to the velocity and also because the direction in which the acceleration is portrayed is on the left-hand side.
Hope this answer helps :)
Answer:
Explanation:
Given:
dI/dt = 6.21 A/s
n = N/l
= 100 turns/cm
= 100 turns/cm × 100 cm/1 m
Radius, r = 14.7 cm
= 0.147 m
Inductance, L = uo × n^2 × A × l
L/l = 4pi × 10^-7 × (100 × 100)^2 × pi × 0.147^2
= 8.53 H
Emf, E = L × dI/dt
E/l = L/l × dI/dt
= 8.53 × 6.21
= 52.98 V/m
=
