How does the value of gravitational

Physics
1 answer:
tester [92]2 years ago
4 0

Explanation:

according to my understanding, the value of gravitational acceleration changes because;different planets have different gravitational pull.

for example you may ask yourself why is it that the gravitational acceleration is not the same on earth and the moon.

this is because the gravitational force acting on an object on earth is greater than the gravitational force acting on an object and the Moon .

You know the moon is located in the space and one can fly, stand,dance etc.

all because the gravitational acceleration is low.

as for me when the distance from the centre of the Earth increases,

the gravitational acceleration decreases.

A good example is given by the moon.

The moon is miles away from the Earth and its gravitational acceleration is quite low .hope you got me.

just olya [345]
<span>I would say greater than because as you do deeper, the pressure strengthens. If you were in a 10 ft deep pool and you dive all the way to the bottom, the ears usually pop. That's because of the pressure. Whereas if you were to go five feet, your ears wouldn't. It depends on the age of the person. Hope this helps.</span>

A circuit with resistive elements of 220, 100, 57, and 43 produce what total resistance?
Korvikt [17]

The total resistance is 420 ohm.

A circuit with resistive elements of 220, 100, 57, and 43 produce what total resistance  

 R= 220+ 100+ 57+ 43

    = 420 Ω

What is resistance and its types?

Resistance is a measure of the opposition to current flow in an electrical circuit also known as ohmic resistance or electrical resistance. Ohms are measured as resistance, symbolized by the Greek letter omega (Ω). The ratio of the applied voltage to the current through the material is then known as resistance.

What causes resistance?

An electric current flows when electrons move through a conductor, such as a metal wire. The moving electrons can collide with the ions in the metal. This makes it more difficult for the current to flow, and causes resistance.

According to the third law of planetary motion, the period of revolution of a planet is related to the planet’s _____.
matrenka [14]
Distance from the sun.

<span>The third law of planetary motion states that the square of the orbital period of a planet is proportional to the cube of the semi-major axis of its orbit</span>. The semi-major axis is the distance from the sun to the epicenter of the ellipse (which would be the planet in question). So, the revolutionary period is directly related to the distance of the planet from the sun.

Two gliders collide on an air track moving in from opposite directions, and they bounce back. The masses of the gliders are 0.20
timurjin [86]

Answer:

so initial momentum is 0.22kgm/s

Explanation:

m1=0.20kg

m2=0.30kg

initial velocity of m1=u1=0.50m/s

initial velocity of m2=u2=0.40m/s

total momentum of the system before collision

Pi=m1u1+m2u2

Pi=0.20kg×0.50m/s+0.30kg×0.40m/s

Pi=0.1kgm/s+0.12kgm/s

Pi=0.22kgm/s
