Answer: Option 4, the satellite D.

Explanation: The gravitational force between two objects is given by the formula:

$F = G\frac{m1*m2}{r^2}$

where m1 and m2 are the masses of the objects, G is a constant, and r is the distance between both objects.

From this equation, you can see that the gravitational force between two objects increments when the masses of the objects increases, and when the distance between the object decreases.

You can see that all the options are at the same distance from the earth, 320km, then the only factor that changes is the mass of the satellite.

And, based on the previous, the satellite with more mass is the satellite that has the greatest gravitational force with the earth, and this would be the satellite D, with amas of 500kg.

Answer:

Satellite D has a mass (kg) of 500 and the distance from Earth (km) is 320.

Explanation:

The universal law of gravitation states that the force between two objects in the universe is directly proportional to the product of their masses and inversely proportional to the square of the distance between them.

We have to choose the satellite having greatest gravitational force with earth. In all options the distance from the earth is same i.e. 320 km. So, we have to select the satellite having maximum mass because the mass of the earth is constant.

Hence, the correct option is (D) " Satellite D has a mass (kg) of 500 and the distance from Earth (km) is 320 ".

What is the mass of a stone moving at a speed of 15 meters/second and having a momentum of 7.5 kilogram - meters / seconds

Elanso [62]

Answer:

0.5 kg

Explanation:

The momentum of an object is defined as

p = mv

where

m is the mass

v is the velocity

In this problem we have,

v = 15 m/s is the velocity of the stone

p = 7.5 kg m/s is the momentum

Solving for m, we can find the mass of the stone:

$m=\frac{p}{v}=\frac{7.5 kg m/s}{15 m/s}=0.5 kg$

Answer: Trough can lift the 403,342 ton pioneering spirit crane vessel 10 meters in 30 seconds as if it was a cork. This about 36 GJ if work and 1 GW of power.

Explanation:

Why trough?

Trough is the correct answer because pioneering scale usually abide only on trough not on the other given options. A long , narrow depression between the waves or ridges is known as a trough. The lower point in the period is the trough.

Speed -: Speed is the distance per unit of time that a body moves. It's a quantity scaler that has just magnitude.
Wave energy -: The transmission and capture of energy by ocean surface waves is wave energy (or wave power). The energy collected is then used for all sorts of useful work, including the generation of electricity, water desalination, and water pumping.
Crest -: A crest point within a cycle on a wave with the highest value of upward displacement. A crest is a point on a surface wave where the medium's displacement is at its height.
Amplitude -: The maximum displacement or distance measured from its equilibrium position, moved by a point on a vibrating body or wave, is called amplitude. It is equal to half of the vibration path's length.
Period-: The duration T is the time needed to pass a given point for one complete cycle of vibration. The wave length decreases as the frequency of a wave increases.
Wavelength-: The distance between two successive crests or troughs of a wave can be described as the wavelength. The frequency is inversely proportional to the wavelength. This implies that the longer the wavelength, the smaller the frequency. Similarly, the shorter the wavelength, the higher the frequency would be.
Frequency -: Frequency defines the number of waves in a given amount of time that travel through a fixed location. In the Hertz unit, frequency is normally measured.
Information -: A piece of data is a basic fact about the identity or properties of an object, i.e. a portion of its example.
Milli -: Milli is known as a merged form meaning 'thousand' (millipede) used in the metric system for unit names equal to one thousandth of the base unit (millimeter) given.

Hence , the answer is TROUGH.

pentagon [3]

Answer:

400 kilogram

Explanation:

Force exerted is directly proportional to the mass of an object.

F=ma where m is mass and a is acceleration. Taking uniform acceleration on all objects then the larger the mass the higher the force and vice versa. Theredore, among the masses given, 400 kilograms is the largest hence it exerts the largest force at the bottom
