Answers
Answer:
The reason you feel weightless is because there is no force pushing against you, since you are not in contact with anything. Gravity is pulling equally on all the particles in your body. This creates a sensation where no forces are acting on you and you feel weightless.

why should we change worn out tyres
Answers
Answer:
Your vehicle's tires work hard every time you go on the road. As they age, they become more and more worn down, especially if you use the same set of tires year round.

What is newton's third law of motion ?Newton's third law of motion states that every action have a equal and opposite reaction . If object A exert force on object B , then object B will also exert an equal and opposite force on object A . Forces result from interaction of two bodies .
As we know according to Newton's third law of motion , when the air rushes out and pushes against the air which pushes the balloon to move in opposite direction , the action of the balloon pushes against the balloon moving it in the backward direction

the mass of earth is 6*10^24 and of mars is 6*10^23 and gravitational force is 6.67*10^16 ,find the distance between their centres.
Answers
Answer:
6× 10¹⁰ metres
Explanation:
F=(G×M1×M2)/r²
(6.67×10¹⁶)=((6.67×10^-11)(6×10²⁴)(6×10²³))/r²
r²=3.6×10²¹
Therefore r=6×10¹⁰ metres
The mass of an object is 4G and it has a density of 5gm^-3. what is the volume

That all changed in the late 1990s, when astronomers started arguing about whether Pluto was indeed a planet. In a highly controversial decision, the International Astronomical Union ultimately decided in 2006 to designate Pluto as a "dwarf planet," reducing the list of the solar system's true planets to just eight.

O The negative force is greater than the positive force.

Answers
Answer:
The net force is positive
Explanation:
This would mean that altogether, the force would cause the object to always be going the same way, and if it is not gaining or losing speed, we can say the force has not changed and that the object has reached terminal velocity. It is not correct to say that the positive is greater than the negative as friction also causes some type of effect and it is neither positive nor negative

An object has a kinetic energy of 8.8J and a mass of 450g. How fast is the object moving?
Answers
Answer:
Explanation:
The formula for KE is
[tex]KE=\frac{1}{2}mv^2[/tex] We have everything we need to solve for the velocity, but we first have to convert the mass from grams to kg:
450 g = .450 kg
[tex]8.8=\frac{1}{2}(.450)v^2[/tex] and we'll rearrange that and solve it for v before we do any math:
[tex]v=\sqrt{\frac{2(8.8)}{.450} }[/tex] so
v = 6.3 m/s rounded to the correct number of sig fig's

7 (a) Smoke particles are introduced into a glass box containing air. Light shines into the box so that, when observed through a microscope, the smoke particles can be seen as bright points of light. Describe the motion of the smoke particles and account for this motion in terms of the air molecules.
Answers
Answer:
smoke particles move in brownian motion (zig -zag motion ) .
Explanation:
this is because air molecules collide against smoke particles hence they attain kinetic energy which keeps them in continuous motion .
The motion of the smoke particles is Brownian motion that is the zigzag motion of the particles that particles move in a random direction.
What is a Brownian Movement?In chemistry, the term "Brownian Movement" refers to the random zigzagging motion of a particle that is typically seen under a high power ultra-microscope. The term "Brownian movement" refers to the exact motion of pollen grains in water, as described by Robert Brown.
More crucially, Albert Einstein eventually clarified the Brownian movement in his study by claiming that water molecules were responsible for moving the pollen. This discovery provided compelling proof that atoms and molecules exist.
According to the question, the reason is that air molecules collide against smoke particles, hence the particles get kinetic energy which keeps them in continuous motion or in zigzag motion.

F = 132N, G = 6.67 x 10⁻¹¹ Nm²/kg², r = .243m, and M₁ = 1.175 x 10⁴ kg, then what is M₂ = ?
Answers
Explanation:
M₂ = Fr²/GM₁
M₂ = [(132N)(.243m)²]/[(6.67*10^-11N*m²/kg)(1.175*10^4kg)]
