Help me plzzz?? I need help it on the picture

madam [21]

No.
The acceleration of gravity on or near Earth's surface is 9.8 m/s² ,
not 20 m/s² .

If it were 20 m/s², then you would weigh almost exactly double
what you really weigh now.

Which two variables must be kept constant during this experiment?

zloy xaker [14]

The number of molecules and the temperature must be kept constant.

Boyle's law is a gas law that states that a gas's pushing force (when it is of a certain mass and maintained at a constant temperature) is in direct opposition to the volume that it occupies. As a result, as long as the temperature and volume of the gas are maintained constant, the pressing factor and volume of the gas are incongruously comparable to one another.

V ∝ 1/P

V = K/P

PV = K

Therefore, the temperature will be the constant variable in Boyle's law. Even though it is the only constant factor, volume, temperature, and pressing factor are all in direct opposition to one another.

A satellite orbits the Earth in the same direction it rotates in a circular orbit above the equator a distance of 250 km from th

UkoKoshka [18]

Answer:

Clock on the satellite is slower than the one present on the earth = 29.376 s

Given:

Distance of satellite from the surface, d = 250 km

Explanation:

Here, the satellite orbits the earth in circular motion, thus the necessary centripetal force is provided by the gravitation force and is given by:

$\frac{mv^{2}}{R} = \frac{GMm}{R^{2}}$

where

v = velocity of the satellite

R = radius of the earth = 6350 km = 6350000 m

G = gravitational constant = $6.674\times 10^{- 11} m^{3}/ks-s^{2}$

M = mass of earth = $5.972\times 10^{24} kg$

Therefore, the above eqn can be written as:

$v = \sqrt{\frac{GM}{R}}$

Now, for relativistic effects:

$\frac{v}{c} = \sqrt{\frac{GM}{Rc^{2}}} = 26.41\times 10^{- 6}$

Now,

r = R + 250

$\frac{v_{surface}}{c} = {\frac{1}{c}\frac{2\pi R}{24} = 1.54\times 10^{-6}$

Ratio of rate of satellite clock to surface clock:

$\frac{\sqrt{1 - \frac{v^{2}}{c^{2}}}}{\sqrt{1 - \frac{v_{surface}^{2}}{c^{2}}}} = 3.43\times 10^{-10}$

Clock on the satellite is slower than the one present on the earth:

$3.43\times 10^{-10}\times 24\times 3600 = 29.376 s$

Suppose the universe were completely empty except for one object- a solid sphere moving through space at a speed of 100km/s. wha

vladimir2022 [97]

Straight linear path

Explanation:

If the universe were completely empty with just one object which is solid moving sphere through the space at a speed of 100km/s, it will move along on a straight path.

An object will continue on a straight path or at rest unless acted upon by an external force. This is the first law of newton.

Since there is no other mass or body in the universe, it will move along in a straight line.
Our planet and other bodies moves in parabolic path and elliptical orbits because they are attracted by the gravitational forces of other bodies.
Any body with mass will attract other bodies and makes it move round it.
The body with the less mass will orbit in the vicinity of the larger mass.
But if we have just one body out there, there is no attraction from any other body, it will continue along it's straight path.
