Two charged objects have a repulsive force of 0.040 N. If the distance separating the objects is doubled, then what is the new force?
Answer:
Force will be 1/4 of the original
Explanation:
F = G m1 m2 / d^2 now change the distance to 2d
F = Gm1m2 / (2d)^2
F = 1/4 G m1 m2 / d^2 the force is reduced to 1/4 of the original

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.

how many grams are in 3 moles of helium?
Answer:
12 g
Explanation:
No of moles = [tex]\frac{mass}{mass.in.1.mole}[/tex]
But we have to find the mass, not the number of moles. So,
Mass = No. of moles × mass in 1 mole
Mass of helium = 4
Mass = 3 × 4
= 12 grams

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.

For an investigation, a teacher dropped a metal bolt into a container of maple syrup and asked students to remove the bolt without touching the syrup. The students first tried to use a strong magnet to remove the bolt, but it remained on the bottom of the container. They finally poured the syrup into another container to get the bolt out. Which of these best describes the bolt’s physical properties?
A.
The bolt is magnetic and less dense than the maple syrup.
B.
The bot is non magnetic and less dense than the maple syrup.
C.
The bolt is non magnetic and more dense than the maple syrup.
D.
The bolt is magnetic and has the same density as the maple syrup.
Choice-C is the right one.
-- The bolt didn't react to the magnet, and just laid there. That tells you that the bolt was made of a non-magnetic material.
-- The bolt didn't float. It went straight to the bottom. That tells you that it's more dense than the fluid around it.
Do magnets have to touch each other for a magnetic field to be present?

What happens to the force between two charged particles if the distance between them is cut in fourth?
Answer: The force between the two charges is directly proportional to the product of the charges and inversely proportional to the square of the distance between them. Hence, if the distance between charges is halved (charges remaining kept constant), the force between the two charges is quadrupled.

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
Hence, The period of the oscillation when Tarzan is swinging back and forth so it should be 5.01 seconds.

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

5. Find mass if a 20N force accelerates an object at 2.5
m/s/s
Hey,
QUESTION )Following the second Newton's Law :
✔ We apply : F = m x a ⇔ m = F/a with F in N, m in kg and a in m/s²
m = 20/2,5 m = 8 kgthe object therefore has a mass of 8 kg
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.
