Answer:
933.804423995 m/s²
Explanation:
= Charge on particle 1 = 67 µC
= Charge on particle 2 = -25 µC
r = Distance between the particles = 47 cm
k = Coulomb constant = 
m = Mass of particle = 73 g
Electric force is given by

The magnitude of force is 68.1677229516 N
Acceleration is given by

The acceleration is 933.804423995 m/s²
A mechanical wave can only travel through matter.
Answer:
v = -0.45 m/s
Explanation:
Assuming the canoe was initially at rest with momentum L = 0
and that the dog's velocity is in the positive direction
conservation of momentum
0 = 15(1.2) + 40v
v = -0.45 m/s
