Explain how Newton’s second law of motion affects a game of Tug of War
Answers
Answer: Newton's second law of motion is F = ma or force is equal to the mass the reason this applies to Newton's third law is because When the game starts, both the sides are pulling the rope and neither side is moving. The force on the rope is the same on each side This is Newton's second law of motion which equates force as mass times acceleration.
Explanation:
Answer:
a force applied to an object at rest causes it to accelerate in the direction of the force
Explanation:
if you tug the rope it goes in your direction when the opposing team does so it goes in their direction. each team pulling on the rope is the force applied to it.
When a bus is moving (especially with a high speed) on the road suddenly stops or suddenly changes its direction, the luggage on the top due to inertia of motion and direction continues to remain in the motion or in the same direction of motion. As a result, the luggage may get thrown out from the bus roof ---is an example of which law of motion?
Answers
Answer:
I believe its Newtons first law.
Explanation:
His first law states that every object will remain at rest or in uniform motion in a straight line unless compelled to change its state by the action of an external force. ... The amount of the change in velocity is determined by Newton's second law of motion.
Which is not an example of vaporization?
Wet pavement dries after a rain shower.
Bubbles form as water boils on the stove.
Water droplets form on a mirror during a shower.
Air gains moisture as it moves over the ocean.
Answers
Water droplets form on a mirror during a shower is not an example of vaporization. So, the correct option is C.
What is Vaporization?Vaporization of an element or compound is defined as the phase transition from liquid phase to vapor. There are two types of Vaporization : evaporation and boiling, while the evaporation is a surface phenomenon and boiling is a bulk phenomenon.
Due to vaporization that results in the increase in temperature, the kinetic energy of the molecules increases. Due to the increase in kinetic energy, the force of attraction between the molecules decreases which results in the vapor being released into the surrounding atmosphere. This process involves the consumption of heat energy.
Thus, Water droplets form on a mirror during a shower is not an example of vaporization. So, the correct option is C.

A box moves 10 m horizontally when force F = 20 N is applied at an angle θ=30° degrees. What is the work done on the box by force F during the displacement?
Answers
Given that,
Distance moved by the box, d = 10 m
Force applies, F = 20 N
It is applied at an angle of 30 degrees.
To find,
The work done on the box by the force F during the displacement.
Solution,
The work done by an object is given by the formula as follows :
[tex]W=Fd\cos\theta\\\\W=20\times 10\cos(30)\\\\W=173.20\ J[/tex]
So, the required work done on the box by the force is 173.20 J.

Uhh... So I put a lightweight neodymium magnet on my plasma ball, and it spun and kept pointing to a direction. How is this happening?
Answers
Answer:
Explanation: The magnet repels the plasma ball, making it turn and go in a certain direction, that’s because neodymium magnet has 2 times repellent force, and plasma balls always have low gravitational pull force so the magnet repellent make it spin on a x or axis and push’s it.

based on Newton's first law of motion describe what happens if you try and push a student. What happens if the student pushes back?
Answers
Answer:
If you push someone, then you are exerting force which will push them into motion. Same goes for when they push you.
Before Galileo and Newton, many people thought objects slowed down because they had a natural built in tendency to do so. But those people weren't taking into account the many forces—e.g., friction, gravity, and air resistance—here on Earth that cause objects to change their velocity. If we could observe the motion of an object in deep interstellar space, we would be able to observe the natural tendencies of an object's motion free from any external influences. In deep interstellar space, we would observe that if an object had a velocity, it would continue moving with that velocity until there was some force to cause a change in the motion. Similarly, if an object were at rest in interstellar space, it would remain at rest until there was a force to cause it to change its motion.
In the video below, we can see that objects in the international space station either remain at rest or continue with constant velocity relative to the space station until acted upon by a force.

If two same forces acting on a body in opposite direction, they will cancel each other. In box 2, 2 N is acting from both top and bottom and it will cancel. Similarly, 5 N is acting from both left and right and result in cancellation in magnitude. Therefore, box 2 cannot be displaced and it is equilibrium.
What is force?Force is an external agent acting on a body to change it from the state of motion or rest. Force is dependent on the mass of the body. Force is a vector quantity and thus, having a magnitude and direction.
If two same forces acting on a body from same directions, then the resultant force will be the sum of the two forces. If these forces are acting in opposite directions, then they will cancel each other in magnitude.
Here, in box 2 equal forces are acting from opposite directions. 2 N from top and bottom will cancel each other and similar for 5 N from left and right. Hence, the net force acting upon the box-2 is zero. Thus, box 2 is said to be in equilibrium.
