Answer:

7400 m/s

Explanation:

Centripetal acceleration = gravity

v² / r = GM / r²

v = √(GM / r)

Given:

G = 6.67×10⁻¹¹ m³/kg/s²

M = 5.98×10²⁴ kg

r = 9.8×10⁵ + 6.357×10⁶ = 7.337×10⁶ m

v = √(6.67×10⁻¹¹ (5.98×10²⁴) / (7.337×10⁶))

v = 7400

The orbital velocity is 7400 m/s.

Who discovered laws of gravity and motion? He discovered aspects of light and color, leading to today's spectrum analysis
Vitek1552 [10]

Answer:

Sir Isaac Newton

Explanation:

The laws according to which bodies move and how one body attracts another body were developed by Newton. The three laws of motion and the law of universal gravitation were developed by Newton.

In the seventeenth century almost all the refracting telescopes exhibited color distortion. Newton believed that white light had a spectrum which was the reason for this distortion. The lens of a refracting telescope used to act like a prism which caused the dispersion of light proving Newton's hypothesis.

mafiozo [28]

The ideal gas constant is a proportionality constant that is added to the ideal gas law to account for pressure (P), volume (V), moles of gas (n), and temperature (T) (R). R, the global gas constant, is 8.314 J/K-1 mol-1.

According to the Ideal Gas Law, a gas's pressure, volume, and temperature may all be compared based on its density or mole value.

The Ideal Gas Law has two fundamental formulas.

PV = nRT, PM = dRT.

P = Atmospheric Pressure

V = Liters of Volume

n = Present Gas Mole Number

R = 0.0821atmLmoL K, the Ideal Gas Law Constant.

T = Kelvin-degree temperature

M stands for Molar Mass of the Gas in grams Mol d for Gas Density in gL.

In two or more complete sentences, explain how you can prove that the number of degrees that the Moon rotates around the Earth e
ioda
In sidereal month, Moon takes about 13 degrees rotation in one day. To get the precise value, you need to know that Moon takes about 27.32 days to complete its one rotation. And in one rotation there are about 360°. Divide 360 by 27.32. You would get 13.18° per day. Therefore, every five days it would be 13.18° * 5 = 65.9°.

However, in synodic month, it takes about 29.53 days. So for one day, its rotation would be 12.19°. For every five days, it would rotate about 12.19° * 5 = 60.95° or 61°. (I think you are talking about the synodic month)

valentina_108 [34]

Answer:before throwing and after catching the ball

Explanation:

When basketball is in the hand of player net force on it zero as holding force is canceled by gravity Force. During its entire motion gravitational force is acting on the ball which is acting downward. Even at highest point gravity is constantly acting downwards.

After catching the ball net force on it zero as holding force is canceled by gravity force and ball is continue to be in stationary motion.
