6.6 miles I think hope this is the right answer.
Assume distance of seperarion is 1m
F.elec = kQq/r^2
charge of a proton: 1.6×10^-19 C
charge of a neutron: 0 C
F.elec = 0 N
F.grav = GMm/r^2
mass of a proton: 1.672621898×10^-27 kg
mass of a neutron: 1.674927471×10^-27 kg
F.grav = (6.67408×10^-11)×(1.674927471×10^-27)×(1.672621898×10^-27)÷(1^2)
F.grav = 1.8699588×10^-64 N
Answer:
The velocity is 
Explanation:
From the question we are told that
The initial speed of the hot water is 
The pressure from the heater 
The height of the hot water before flowing is 
The height of bathtub above the heater is 
The pressure in the pipe is 
The density of water is 
Apply Bernoulli equation
Substituting values
=> ![v_2^2 = \frac{ (450 *10^{3}) + (1000 * 9.8 *0 ) + (0.5 * 1000 * 0.85^2) -[ (1000 * *9.8*3.70) ]}{0.5*1000}](https://tex.z-dn.net/?f=v_2%5E2%20%3D%20%20%5Cfrac%7B%20%28450%20%2A10%5E%7B3%7D%29%20%2B%20%281000%20%2A%209.8%20%2A0%20%29%20%2B%20%280.5%20%2A%201000%20%2A%200.85%5E2%29%20-%5B%20%281000%20%2A%20%2A9.8%2A3.70%29%20%5D%7D%7B0.5%2A1000%7D)

=>
It makes an echo and it circles around it.
The box accelerates at 1. 0 m/s² to the right because the net force is 17N to the right . This statement clearly depicts the relation between force and acceleration. Hence option A is correct.
<h3>What is acceleration?</h3>
Acceleration is defined as the rate of change of the velocity of the body. Its unit is m/sec².It is a vector quantity. It requires both magnitudes as well as direction to define.
According to Newton's second law of motion, the net force acting on the body is equal to the product of mass and acceleration of the body.
The direction of acceleration is in the direction of net force acted.
Hence option A is correct.
