The answer is 18000 kgm/s
Momentum is mass times velocity so just do 750•24.
Answer:

Explanation:
Given that,
The distance between two spheres, r = 25 cm = 0.25 m
The capacitance, C = 26 pF = 26×10⁻¹² F
Charge, Q = 12 nC = 12 × 10⁻⁹ C
We need to find the work done in moving the charge. We know that, work done is given by :

Put all the values,

So, the work done is
.
The answer would be 27,000 Joules because (1/2) m v^2 =30*900 which equals 27,000 J
Friction between the ball and the floor is stealing some of the kinetic energy of the ball, and turning it into heat.
Answer:
Normal force = 8.75 N
Explanation:
given,
frictional force between the steel spatula and the Teflon frying pan=0.350 N
coefficient of friction between material =0.04
normal force = ?
using formula,
Frictional force = coefficient of friction × normal force


Normal force = 8.75 N
