what is the magnitude of the gravitational force on each mass when m1=600 kg m2=400 kg, and their centers are 6 m apart? (choices shown in image)
Edit: I didn't realize there is a simulation for this question, so I used the simulation and got 4.45 x 10^-7, if anybody needs the answer
Answer:
4.45×10¯⁷ N
Explanation:
The following data were obtained from the question:
Mass 1 (M₁) = 600 Kg
Mass 2 (M₂) = 400 Kg
Gravitational constant (G) = 6.67×10¯¹¹ Nm²Kg¯²
Sperating distance (r) = 6 m
Force (F) =.?
The gravitational force can be obtained as follow:
F = GM₁M₂ / r²
F = 6.67×10¯¹¹ × 600 × 400 / 6²
F = 1.6008×10¯⁵ / 36
F = 4.45×10¯⁷ N
Therefore, the gravitational force is 4.45×10¯⁷ N

a= F/m
a= 39/10
a= 3.9m/s^2
Why was Democritus considered a philosopher and not a scientist?
Answer:
Democritus had no scientific instruments to extend the reach of his senses, so all of his experiments were just 'mind experiments', but because Democritus was a philosopher, he thought more into depth about why we humans are alive which led to the atomic theory.

what is the weight of a 500 kg boulder on the moon?
Answer:
F = 810 [N]
Explanation:
To solve this problem we must use the acceleration of gravity of the moon, which according to information provided by the internet we can see that the gravitational acceleration corresponds to 1.62 [m/s^2].
The weight of a body corresponds to the product of mass by gravity, so with the following equation we can find the weight.
F =m*g
F = 500 * 1.62
F = 810 [N]
A ball is dropped off the side of a bridge after 1.55 seconds how far has it fallen (units=m)
Answer:
d = 11.77 m
Explanation:
Given that,
A ball is droped off the side of a bridge after 1.55 seconds.
We need to find how far it has fallen.
It will fall under the action of gravity. It would mean that a = g = 9.8 m/s²
Let it is fallen at a distance d. d can be calculated using second equation of motion as follows :
[tex]d=ut+\dfrac{1}{2}at^2[/tex]
Put u = 0 and a = g
So,
[tex]d=\dfrac{1}{2}\times 9.8\times (1.55)^2\\\\d=11.77\ m[/tex]
Hence, it will fall at a distance of 11.77 m.

what difference will you get from the flying or air filled balloon and the hydrogen filled balloon.
Answer:Since most of air is made of nitrogen and oxygen, which have heavier molecular weights than hydrogen, air is denser than the hydrogen-filled balloon (the atmosphere is denser than the hydrogen-filled balloon). This results in the balloon floating in the air!

Noah Formula is in airplane which is flying at constant speed in a circular course of radius 5000 m., circling O'Hare Airport prior to landing. Noah observes that the plane completes each round trip in 400 seconds. What is the speed of the airplane? What is centripetal acceleration?
Answer:
(a). The speed of the airplane is 78.53 m/s.
(b). The centripetal acceleration 1.234 m/s².
Explanation:
Given that,
Radius = 5000 m
Time = 400 second
We need to calculate the speed of the airplane
Using formula of speed
[tex]v=\dfrac{d}{t}[/tex]
[tex]v= \dfrac{2\pi r}{t}[/tex]
Put the value into the formula
[tex]v=\dfrac{2\times\pi\times5000}{400}[/tex]
[tex]v=78.53\ m/s[/tex]
We need to calculate the centripetal acceleration
Using formula formula
[tex]a=\dfrac{v^2}{r}[/tex]
Put the value into the formula
[tex]a=\dfrac{78.53^2}{5000}[/tex]
[tex]a=1.234\ m/s^2[/tex]
Hence, (a). The speed of the airplane is 78.53 m/s.
(b). The centripetal acceleration 1.234 m/s².

What is centrifugal force?A fictitious force that moves in a circle and is directed away from the center of the circle is called centrifugal force. When measurements are taken in an inertial frame of reference, the force does not exist. It only becomes relevant when we switch from a ground/inertial reference frame to a rotating reference frame.
The centrifugal force's unit is newton.
As the gravitational force is balanced by centrifugal force is orbital motion:
Gravitational force =centrifugal force
GMm/r² = mv²/r
v² = GM/r
v = √( GM/r)
= √(6.67×10⁻¹¹ ×4.76 ×10²⁶/6.27 ×10⁸)
= 7.12 × 10³ m/s.
Hence, The speed of the spaceship is 7.12 × 10³ m/s. Hence, option (A) is correct.

A. What did the neuron say to the muscle say? (Use your basic physiological knowledge, such as the function of
neurons and muscles, to answer the question)
Answer:
Somatic motor neurons originate in the central nervous system, project their axons to skeletal muscles (such as the muscles of the limbs, abdominal, and intercostal muscles), which are involved in locomotion.
Explanation:
Muscles move on commands from the brain. Single nerve cells in the spinal cord, called motor neurons, are the only way the brain connects to muscles. When a motor neuron inside the spinal cord fires, an impulse goes out from it to the muscles on a long, very thin extension of that single cell called an axon.

Why is Mercury usedcommonly
as Thermometric substance?
Answer:
Mercury is the only one in liquid state at room temperature. It's used in thermometers because it has high coefficient of expansion.
Explanation:
Hence, the slightest change in temperature is notable when it's used in a thermometer. It also has a high boiling point which makes it very suitable to measure higher temperatures.

sonia has three different sized blocks of copper . she made observations and mesaurements of each block. which of her measurements would be different ?
Answer:
This question lacks options, the options are:
A.The density of each block.
B.The electrical conductivity of each block.
C.The melting point of each block.
D.The volume of each block
The answer is D. Volume of each block
Explanation:
According to this question, Sonia has three blocks of different sizes. She then made observations and measurements of each block. The physical property of a substance that depends on the size of that substance is called EXTENSIVE PROPERTIES. This include mass, height, volume, length etc.
In this case, the different measurement Sonia will record on each copper block will be the VOLUME OF EACH BLOCK. This is because the volume depends on the size of the block (extensive), hence, will have different volume measurements.

A box is suspended from a crane at a height of 32 m from the ground. The box has 7840 j of gravitational potential energy. What is the mass of the box
Answer:
The mass of the box is 24.97 [kg]
Explanation:
In order to solve this problem, we must use the concept of potential energy, which is defined as the product of mass by gravity by height. So we have the following equation.
[tex]E_{p} =m*g*h[/tex]
where:
Ep = potential energy [J]
m = mass [kg]
g = gravity acceleration = 9.81 [m/s^2]
h = elevation = 32 [m]
7840 = m*9.81*32
m = 24.97 [kg]

what is statement can most likey be useing in the shock waves of atmoic bomb
Answer:
The initial energy emission occurs by 80% or more in the form of gamma rays but these are quickly absorbed and dispersed mostly by air in little more than a microsecond, converting gamma radiation into thermal radiation (thermal pulse ) and kinetic energy (shock wave) which are actually the two dominant effects in the initial moments of the explosion. The rest of the energy is released in the form of delayed radiation (fallout or fallout) and is not always counted when measuring the performance of the explosion.
Explanation:
High altitude explosions produce greater damage and extreme radiation flux due to lower air density (photons encounter less opposition) and consequently a higher blast wave is generated.

1. A car accelerates uniformly from 12 m/s to 39 m/s in 12 seconds. What is the car's average acceleration
2. A butterfly is flying at 4 m/s. It accelerates uniformly at 1.2 m/s for 6 seconds. How far does the butterfly travel during the period of acceleration?
Answer:
(1) 2.25m/s^2
(2) 45.6m
Explanation:
(1) A car accelerates uniformly from 12m/s to 39m/s in 12 seconds
Therefore the average acceleration can be calculated as follows
a = 39-12/12
a = 27/12
a= 2.25m/s^2
(2) A butterfly is flying at 4m/s , it accelerates uniformly at 1.2 m/s for 6 seconds
u= 4
a= 1.2
t= 6
Therefore the distance can be calculated as follows
S= ut + 1/2at^2
= 4×6 + 1/2 × 1.2 × 6^2
= 24 + 1/2 × 1.2 × 36
= 24 + 1/2 × 43.2
= 24 + 21.6
S = 45.6m
Hence the butterfly travels at 45.6m
