<span>The correct option is C. Gravity, and the complete sentence is: "The force of gravity is the force at which the Earth attracts another object towards itself". In fact, the force of gravity between two objects is given by
</span>F= \frac{Gm_1m_2}{r^2}<span>
where G is the gravitational constant, m1 and m2 the masses of the two objects, r their separation. If we take the Earth as one of the two objects, then m1 represents the Earth's mass, m2 the mass of the object and r the distance between the center of Earth and the object, and F is the gravitational force at which the Earth attracts the object.</span>

Correct answer choice is:

C) gravity


Explanation:

Gravity is a force of attraction that endures within any two bodies, any two groups, any two particles. Gravity is not just the attraction among objects and the Earth. Gravity is a force pulling mutually all matter. The longer matter, the more gravity, so things that have a lot of material such as planets and moons and stars pull more firmly. Mass is how we estimate the amount of matter in something.

A guitar string vibrates at a frequency of 330Hz with wavelength 1.40m. The frequency and wavelength of this sound wave in air (
bixtya [17]

Answer:

Same frequency, shorter wavelength

Explanation:

The speed of a wave is given by

v=f\lambda

\lambda=\dfrac{v}{f}

where,

f = Frequency

\lambda = Wavelength

It can be seen that the wavelength is directly proportional to the velocity.

Here the frequency of the sound does not change.

But the velocity of the sound in air is slower.

Hence, the frequency remains same and the wavelength shortens.

The planet Krypton has a mass of 8.8 × 1023 kg and radius of 2.5 × 106 m. What is the acceleration of an object in free fall nea
djverab [1.8K]

Answer:

Acceleration, a=9.39\ m/s^2

Explanation:

Given that,

Mass of the planet Krypton, m=8.8\times 10^{23}\ kg

Radius of the planet Krypton, r=2.5\times 10^{6}\ m

Value of gravitational constant, G=6.6726\times 10^{-11}\ Nm^2/kg^2

To find,

The acceleration of an object in free fall near the surface of Krypton.

Solution,

The relation for the acceleration of the object is given by the below formula as :

a=\dfrac{Gm}{r^2}

a=\dfrac{6.6726\times 10^{-11}\times 8.8\times 10^{23}}{(2.5\times 10^{6})^2}

a=9.39\ m/s^2

So, the value of acceleration of an object in free fall near the surface of Krypton is 9.39\ m/s^2

A jet travels at 489 meters per second how long does it take to travel 235 m? answer in seconds
Sladkaya [172]

if in 1 second the jet goes 428 meters and you want to know how long it takes to go 237 meters you just divide 237/428  

it can be written like this  

_1_ = __x__  

428 237  

cross multiply  

428 times x = 1 times 237  

428x=237  

divide by 428 on both sides  

x= 237/428  

x=0.5537 seconds
