A meteroid is in a circular orbit 600 km above the surface of a distant planet. the planet has the same mass as Earth but has a

radius that is 90% of Earths (where Earths radius is approximately 6370 km).
The acceleration of the meteroid due to the gravitational force exerted by the planet is most nearly

A) 9 m/s^2 toward the center of the planet

B) 9 m/s^2 in the direction of the meteoroids motion

Well, the answer to this question is D) 10 m/s^2 in the direction of the meteoroids motion.
Glad I could help and have a fantastic day!
Also, can you please mark my answer as the brainliest answer?
Thanks.

Answer:

C)  10 m/s^2 toward the center of the planet

Explanation:

g = GM/r^2

The masses of earth and this planet are the same and the radius is only diffferent by 10% so as gravitational force acceleration is 9.8m/s^2 on earth, it can be estimated to be around 10m/s^2.

Using the third law, we know acceleration is toward the larger mass from attraction, thus having it point toward the center of the planet.

Triss [41]

Here the weight is hung from the thread inside the ceiling of train

now the FBD of train is analysed

We can say

Tcos\theta = mg

Tsin\theta = ma

now by ratio of two equations we have

a = gtan\theta

this shows that train must be in accelerating condition due to which the thread is making an angle with the vertical

now we will have

2 The train is not an inertial frame of reference.

Since train is accelerating so it must be non inertial frame

5 The train may be moving at a constant speed in a circle.

Since its moving in circle so it is in accelerating condition

8 The train must be accelerating.

What do you notice about the lines of earthquakes and volcanoes and where they seem to occur on Earth's surface?
Stolb23 [73]

Answer:

Most earthquakes and volcanoes occur because of the movement of the plates, especially as plates interact at their edges or boundaries.

Having established that a sound wave corresponds to pressure fluctuations in the medium, what can you conclude about the directi
DaniilM [7]

Answer:

the pressure fluctuation is LONGITUDINAL

Explanation:

Sound waves are an oscillating movement of air particles, this can be analyzed in two different, but equivalent ways, as an air oscillation and with a pressure wave due to these oscillations.

The expression for the wave is

        ΔP = Δo sin (kx - wt)

Therefore, the pressure variation is in the same direction as the displacement variation, consequently the pressure fluctuation is LONGITUDINAL

The heat anticipator in a thermostat control circuit in the heating mode is active when the Heating contact is closed. 
The heat anticipator fine tunes the point at which the thermostat turns off the furnace burners. When the heat anticipator in a thermostat is out of adjustment, it can cause the furnace to exhibit symptoms of short cycling or to exceed or never reach the desired thermostat heat setting.
