Answer:
Mass is the inertia of object. Momentum is the inertia in motion.
Explanation:
Mass:- Mass is the measurement of inertia. Mass of an object depends upon number of atoms present in a object. its unit is kg. mass is the inertia of object.
Momentum:- It is the product of Mass And velocity.
Momentum is given by the formula P = m × v
Momentum is the inertia in motion. it increases with increase of mass , velocity or both increases.
Momentum unit is
.
Answer:
b) Distance covered before stopping.
Explanation:
If you want to find the distance d required to come to a stop starting at some initial speed v, with braking acceleration a, use the kinematic relation
vf2 - vi2 = 2ad
vi = initial speed at the moment braking begins = v
vf = final speed = 0 (comes to a full stop)
-v2 = 2ad
d = -v2/(2a)
Answer:
both an electric field and a magnetic field
Explanation:
Answer:
2.42×10⁷ s
Explanation:
From the question above,
Applying,
Q = It.................... Equation 1
Where Q = quantity of charge in coulombs, I = electric current in Ampere, t = time in seconds
make t the subject of the equation
t = Q/I................ Equation 2
Given: Q = 10900 C, I = 0.450 mA = 4.5×10⁻⁴ A
Substitute these values into equation 2
t = 10900/(4.5×10⁻⁴)
t = 2.42×10⁷ s
Hence the clock runs for 2.42×10⁷ s
