Newton’s second law of motion seems simple enough: Push on an object of a certain mass, and it accelerates based on the amount of force and mass. A small force with a large mass results in a slow acceleration, and a large force with a small mass gives a fast acceleration. What happens when there’s no force? A force of zero on any mass gives zero acceleration. If the object is standing still, it remains still; if it’s moving, it continues to move at the same speed and direction. Keep in mind that several forces can be involved at the same time. For example, you tie a rope around a boulder and pull with all your might. There are force and mass, but the boulder doesn’t budge, so acceleration is zero. The force of friction between the boulder and the ground cancels out the force of your pull. You need a much bigger force, such as from a tractor, to move the boulder.
Answer:
Force ∝ Acceleration
Explanation:
Force is directly proportional to acceleration. This is because as you increase force, the acceleration increases.

Explanation:
Answer:
I think it's A. Commander in Chief
Explanation:
Particle A and particle B are held together with a compressed spring between them. When they are released, the spring pushes them apart, and they then fly off in opposite directions, free of the spring. The mass of A is 5.00 times the mass of B, and the energy stored in the spring was 46 J. Assume that the spring has negligible mass and that all its stored energy is transferred to the particles. Once that transfer is complete, what are the kinetic energies of each particle?
Answer:
Particle A: K.E = 38.3 J
Particle B: K.E = 7.67 J
Explanation:
Given that Particle A and particle B are held together with a compressed spring between them. When they are released, the spring pushes them apart, and they then fly off in opposite directions, free of the spring. The mass of A is 5.00 times the mass of B, and the energy stored in the spring was 46 J. Assume that the spring has negligible mass and that all its stored energy is transferred to the particles. Once that transfer is complete, what are the kinetic energies of each particle?
The total kinetic energy of Particle A and particle B should be equal to 46 J
Since the mass of A is 5.00 times the mass of B, then, the K.E energy of each particle can be calculated by using ratio.
5 + 1 = 6
K.E for particle A
5 /6 × 46 = 230 / 6 = 38.3 J
K.E for particle B
1/6 × 46 = 46 / 6 = 7.67 J
Number of protons are equal to the number of electrons

A person stands 6.00 m from a speaker, and 8.00 m from an identical speaker. What is the frequency of the second (n = 2) interference maximum (constructive)? (Hint: v= xf = 343 m/s) (Unit = Hz)
Answer: 343
Explanation: i know it sounds weird but its right
The frequency for the maximum constructive interference will be 343 Hz.
What is the interference of waves?The result of two or more wave trains flowing in opposite directions on a crossing or coinciding pathways. This phenomenon is known as the interference of waves.
The effect is the sum of the individual wave amplitudes at each site where more than one wave is present.
From the constructive interference;
[tex]\rm L_1-L_2 = 2 \lambda \\\\ 2\lambda=8-6 \\\\ \lambda= 1 \ m[/tex]
The frequency is;
[tex]\rm f= \frac{c}{\lambda} \\\\ f= \frac{343}{1} \\\\ f= 343 \ Hz[/tex]
Hence,the frequency for the maximum constructive interference will be 343 Hz.

A circle graph shows that one-fourth of the students in a particular school ride the bus every day. What is this equivalent measurement in radians? In degrees?
Answer:
it's 1.57... radians and 90°
As par circle graph, π/2 radian part of total number of the students in a particular school ride the bus every day.
What is circle graph?Pie charts are another name for circle graphs. The graph is shaped like a circle, with many wedges that each represent a portion of the overall.
The circle graph is commonly referred to as a pie chart since these wedges frequently resemble pie slices. The circle graph's angles are proportionate to the quantity they each represent.
According to circle graph:
Total number of student in the particular school = 2π radian.
So, one-fourth of total number of student in the particular school = 2π/4 radian
= π/2 radian.
Hence, according to circle graph, π/2 radian part of total number of the students in a particular school ride the bus every day.

A coin falls off a table and is traveling to the ground. Which claim about the forces acting on the coin must be true?
(Choice A)
There is a net force on the coin.
(Choice B)
There are no forces on the coin.
(Choice C)
There is no net force on the coin.
(Choice D)
There is not enough information.
A coin falls off a table and is traveling to the ground. There is a net force on the coin which is responsible for the motion of the coin. Thus, the correct option is A.
What is Net force?The net force can be defined as is the sum of all the forces which are acting on an object. Net force acting upon an object can accelerate its mass. Some other forces also acts on a body either at rest or motion. The net force is used in a system when there is a significant number of forces acting on the object.
A coin which falls off a table and is still traveling to the ground. Then, it can be concluded that there is a net force which is acting on that coin which is responsible for the motion of the coin.
Therefore, the correct option is A.

how does the sun rise and set
a.earth orbit around the sun
b.The sun is center of solar system
c.earth rotates on it tilted axis and orbit around the sun at the same time
Answer:
c. earth rotates on it tilted axis and orbit around the sun at the same time
Explanation:
Earth rotation can be defined as the amount of time taken by planet earth to complete its spinning movement on its axis.
This ultimately implies that, the rotation of earth refers to the time taken by earth to rotate once on its axis. One spinning movement of the earth on its axis takes approximately 24 hours to complete with respect to the sun. Thus, this makes us to experience day and night (sun rise and sun set) due to the rotation of planet about its axis.
Hence, the sun rise and set because the earth rotates on it tilted axis and orbit around the sun at the same time

Answer:
i don`t get it
Explanation:
Velocity can be described as the same thing as speed but with _________________ included
Answer:
Direction
Explanation: Hope this helps!
Answer:
nvm its direction :))
Explanation:
Speed and velocity both represent a way to measure the change in position of an object relative to time. In fact, for a straight line motion, the speed and velocity of an object are the same (since distance and displacement will be the same). Speed and velocity are measured in the same units: meters per second or m/s.
Velocity is a measure of both speed and direction of motion. Velocity is a vector, which is a measurement that includes both size and direction. Velocity can be represented by an arrow, with the length of the arrow representing speed and the way the arrow points representing direction.

Tarzan is swinging back and forth
on a 6.25 m long vine. What is the
period of his oscillation?
(Unit = s)
Answer:
5.02s
Explanation:
I got it right in acellus :)
The period of the oscillation when Tarzan is swinging back and forth so it should be 5.01 seconds.
Calculation of the period:Since
Length L = 6.25 m
g = 9.8 m/s²
So,
T = 2π√(L/g)
T = 2π√(6.25 / 9.8)
T = 5.01 sec
