Explain Newton's Law Of Gravity, and explain how the formula works correctly and combines mathematical arithmetic to figure out gravity.
Answer:
Explanation:
Newton's Law Of Gravity states two masses will have an attraction force that is proportional to their masses and inversely proportional to the square of their separating distance.
Mathematically it is expressed as Force = G * M1 * M2 / d^2 where
G is the gravitational constant, M1 and M2 are the masses and d is the separating distance.
The change in momentum (and impulse) are still 3000 N*s. Safety devices (like airbags, seatbelts and crumple zones) cause crashes to take more time to occur. Now the crash takes 1.5 seconds. How much force is exerted on you in this case? *
Answer:
F = 2000 N
Explanation:
According to Newton's Second Law of Motion, the rate of change of momentum is equal to the force applied. Therefore, the formula written below will be used to solve this problem:
[tex]F = \frac{\Delta P}{t}\\\\[/tex]
where,
F = Force everted = ?
ΔP = Cange in Momentum = 3000 N.s
t = time taken = 1.5 s
Therefore,
[tex]F = \frac{3000\ N.s}{1.5\ s}[/tex]
F = 2000 N

In a symbiotic relationship,
a. one organism benefits while its host gets nothing in return.
b. bacteria takes food from your stomach, but does nothing for you.
c. both organisms involved benefit or are neutrally affected.
d. your body produces vitamins and then uses them for nutrition
In a symbiotic relationship, both organisms involved benefit or are neutrally affected. Symbiosis is a close and long-term interaction between two different species.
The term "symbiosis" encompasses mutualism, commensalism, and parasitism. In mutualism, both organisms benefit from the interaction, such as in the case of bees and flowers where bees obtain nectar and pollen while also helping flowers to pollinate.
In commensalism, one organism benefits while the other is neither helped nor harmed, such as remora fish that attach to sharks for transportation and feeding on scraps left by the shark. In parasitism, one organism benefits while the other is harmed, such as ticks that feed on blood from a host animal.

A flower pot with a mass of 1.2 kg is sitting on a ninth story windowsill 30 meters above the ground. How many joules of energy does the flower pot have? Is the energy potential energy or kinetic energy?
Pt.2
USE THE QUESTION ABOVE: The owner of the flower pot gave it to a friend who lived on the second floor of the
apartment building. This person also put it on their windowsill which was 6 meters above the ground? Now how
much gravitational potential energy would the flower pot have now?
Answer:
(assuming gravity = 10m/s2)
answer for part 1 :
the pot will possess potential energy and not kinetic energy.
the energy which the pot possess is = PE of the pot
PE = mgh = 1.2x 10 x 30 = 360 J
answer for part 2 :
PE = mgh = 1.2 × 10 × 6 = 72 J
Explanation:
the PE of a body is not due to its state of motion, its due to the state of rest of the body. when the body starts moving it possess kinetic energy.
a vehicle is moving with 20m/s towards the east and another is moving 15m/s towards the west
Answer:
5 m/s
Explanation:
Given that,
A vehicle is moving with 20m/s towards the east and another is moving 15m/s towards the west.
It is assumed to find the resultant velocity of the vehicle. Let east side is positive and west is negative. So,
[tex]v=v_1+v_2\\\\=20+(-15)\\\\=5\ m/s[/tex]
Hence, the resultant velocity of the vehicle is equal to 5 m/s.

If the distance between us and a star is doubled, with everything else remaining the same, the luminosity If the distance between us and a star is doubled, with everything else remaining the same, the luminosity remains the same, but the apparent brightness is decreased by a factor of two. is decreased by a factor of four, but the apparent brightness remains the same. is decreased by a factor of two, and the apparent brightness is decreased by a factor of two. remains the same, but the apparent brightness is decreased by a factor of four. is decreased by a factor of four, and the apparent brightness is decreased by a factor of four.
Answer:
The luminosity remains the same, but the apparent brightness is decreased by a factor of four.
Explanation:
The apparent brightness, F = L/4πr² where L = luminosity and r = distance between us and the star.
Since L is independent of the distance between us and the star, it is constant, then
F ∝ 1/r²
So, F₁/F₂ = r₂²/r₁² where F₁ = apparent brightness at r₁ and F₂ = apparent brightness at r₂
If the distance is doubled, that is r₂ = 2r₁, then
F₁/F₂ = r₂²/r₁²
F₁/F₂ = (2r₁)²/r₁²
F₁/F₂ = 4r₁²/r₁²
F₁/F₂ = 4
F₂ = F₁/4
So, since the luminosity is constant, the luminosity remains the same, but the apparent brightness is decreased by a factor of four.

What is the difference between sounds that have the same pitch and loudness? the standing wave the natural frequency the sound quality the resonance
Answer:
Sound quality
Explanation:
Loudness refers to the property of sound that depends on the amplitude of the sound wave while pitch is the property of sound that depends on the frequency of the sound wave.
Now, when sounds have the same pitch and loudness, it means they possess the same natural frequency and also, they will have similar resonance and standing waves. Despite all these similarities, the quality of these sounds will tend to vary from one to another.

C) the sound quality

The angular velocity is the ration of the change in the angle turned to time.
Why does the angular velocity increase?The angular velocity is the ration of the change in the angle turned to time. As such, the angular velocity is measured in radians per second. We have been told that the athlete is supposed to perform the jump between figures 1 and 2 in multiple somersaults.
Each time the athlete somersaults, the angular velocity changes. As such, the rate of change of the angular velocity between figures 1 and 2 would be quite high.
On the other hand, the athlete jumps straight vertically down between figures 2 and 3 and does not turn. Hence, the angular velocity decreases.
