Groups of students are measuring the masses of several rocks. They have a scale that can show readings in pounds or kilograms. The teacher requires that they all make their measurements in kilograms.Why would the teacher make a decision like this? Choose 1 answer: (Choice A) A kilogram is larger than a pound, so the scale could measure more massive rocks. (Choice B) Accurate measurements cannot be made in pounds. (Choice C) Pounds cannot be converted to kilograms. (Choice D) It is easier to compare measurements when using the same unit system.

How does the electric potential energy between two charged particles change if one particle's charge is increased by a factor of 2?

Answers

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

$U = (kq_1q_2)/(r)$

now we know that if the charge of one of the charge particle is increased to twice of initial charge then

$U' = (kq_1(2q_2))/(r)$

now we can say from above two equations that

$U' = 2U$

so on increase one of the charge to twice of initial value then the potential energy will become TWICE

from the formula of electric potential = (1/4πe)*(Qq/r), if one of the charge is doubled, the electric potential energy would be doubled too. Not so sure though, u might wanna double-check with someone else. But hope that helps. :)

Displacement vectors of 5 km north, 3 km east, 2 km south, and 3 km west combine to a total displacement of___. A. 3 km north.. B. 13 km west.. C. 0 km.. D. 2 km south..

Answers

The answer is A. 3 km north

Displacement (D) is the shortest distance from the initial to the final position.
In this example distance is 5 km north - 2 km south = 3 km north (look at the image).

Answer: Forces and Motion Unit Test (Connexus)

1. A. 3 km north

2.B. The airplane

3. C. at a particular instant

4. D. all of the above

5. C. the front seat of the car

6. C. inertia

7. C. one-third its weight on Earth's surface

8.D. gravity

9.D. all of the above

10. C. Pascal's principle

11.D. The weight of the balloon is less than the weight of the air displaced by the balloon

17. force,mass

18. increases

19.equally

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.

C. 3rd Law
D. All of Newton's Laws

Answers

Squids and octopuses forcefully expel water through the siphon after ingesting it, propelling themselves through the water. Third Law of Newton.

Describe the third law of Newton's law?

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.

What are examples of the third law of Newton?

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.
