Answer:
Magnitude of potential energy is increased by factor "2"
Explanation:
As we know that if two charge particles are placed at some distance "r" from each other then the electrostatic potential energy between two charge particles is given as
now we know that if the charge of one of the charge particle is increased to twice of initial charge then
now we can say from above two equations that
so on increase one of the charge to twice of initial value then the potential energy will become TWICE

20. Speed is the distance traveled by an object where as, velocity is distance traveled by an object per unit time in a particular direction. Speed is a scaler quantity where as velocity is a vector quantity.
21. Acceleration is the rate of change, which means the change in velocity (vf-vi) with time(t) Where vf if the final velocity and vi is the initial velocity
22. Acceleration can be described as changes in speed, direction or both. The ball is moving at a constant speed, but its direction is changing continuously Because it's direction is changing, the ball is experiencing continuous acceleration.
23. For graph A, I can say that velocity is constant until it reaches time of 8 seconds and a constant velocity is again exhibited starting at time 12 seconds
24. For Graph B, the velocity is changing as time pass by since the slope is changing, At time of 2 seconds, graph A has greater velocity since it has a steeper slope.
25. 300 meters
26. Graph A shows greater velocity because Graph A has a steeper slope than Graph B.
27. 38 kg * 2.2 m/s=83.6 kg-m/s
28. The pressure inside the tube is greater than the pressure outside the tube because primarily of the smaller area of the tube. This increases up the pressure and let the fluid rise up.
29. The fertilizer is pushed up the tube.
Explanation: I hope this helps :)
propulsion is an example of which Newton's Law?
A. 1st Law
B. 2nd Law
C. 3rd Law
D. All of Newton's Laws
Squids and octopuses forcefully expel water through the siphon after ingesting it, propelling themselves through the water. Third Law of Newton.
His third law asserts that there is an opposite and an equal response in nature for every action (force). When an object A pulls on an object B, the opposite force is applied to the first object by object B. Alternatively said, interactions lead to forces.
There are numerous real-world applications of Newton's third motion law. For instance, when you leap, the earth exerts an equal and opposing reaction force that propels you into to the air. This is because when you apply a force to it with your legs, it responds in kind. Rockets and other projectiles are designed using Newton's third law by engineers.

Answer:
v = 7 m/s
Explanation:
p = m × v
42 = 6 × v
6v = 42
v = 42/6
v = 7 m/s
