Answer:

Maximum gravitational Force: F_{gmax} = 1,026*10^{-08} N

Explanation:

The maximum gravitational force is achieved when the center of gravity are the closer they can be. For the spheres the center of gravity is at the center of it, so the closer this two centers of gravity can be is:

bowling ball radius + billiard ball radius = 0,128 m

The general equation for the magnitude of gravitational force is:

F_{gmax}  = G \frac{M*m}{r_{min}^{2} }

Solving for:

G = 6,67*10^{-11}  \frac{Nm^{2}}{kg^{2}}

M = 7,2 kg

m = 0,35 kg

r_{min} = 0,128 m

The result is:

F_{gmax} = 1,026*10^{-08} N

What fraction of the carbon dioxide exhaled by animals is generated by the reactions of the citric acid cycle
puteri [66]

Answer:

1/3

Explanation:

Pyruvate is produced by the glycolysis in cytoplasm. The oxidation of pyruvate takes place in mitochondrial matrix.  

Pyruvate is converted to acetyl-CoA in the reaction given below:

Pyruvate + NAD⁺ + CoA-SH ⇒ acetyl-CoA + NADH + CO₂

1 molecule of carbon dioxide is eliminated from 1 molecule of pyruvate.

Also,  

2 molecules of carbon dioxide is eliminated from 2 molecules of pyruvate (as glucose on glycolysis yields 2 molecules of pyruvate).

Also, acetyl-CoA further goes into the citric acid cycle and produces 2 molecules of carbon dioxide.

Thus pyruvate produces total 3 molecules of CO₂  and hence glucose produces 6 molecules of CO₂ (as glucose on glycolysis yields 2 molecules of pyruvate)

Thus,

<u>Fraction = 2/6 = 1/3</u>

Answer:

1.Magnetosphere

2.Liquid Outer core

3.Atmosphere

4.Lightening

5.Biosphere

6.Blue

7.Dolphins

8.Hydrosphere

9.Ice Caps

10.Lithosphere

11.Latitude

12.Longitude

Explanation:

The invisible field that protect us from solar radiation is called Magnetosphere.

This protective field is created by movement between solid inner core and earth's Liquid outer core.

The layer of gases is called atmosphere.

In addition to wind , rain , lightening is observed on stormy night.

Because of water earth looks Blue.

Dolphins are just one of the animals that calls the hydrosphere, its home.

Ice caps in the north and south poles.

Rocky layer of solid earth is part of Lithosphere.

A race car is driven by a professional driver at 99 . What is this speed in and ? 1 mile = 1.61 kilometers 1 hour = 60 minutes E
slavikrds [6]

Answer: The speed is equivalent to <u>159.39 kilometers per hour </u>or <u>2.65 kilometers per minute.</u>

Explanation:

Given, The speed of a race car = 99 miles/ hour

To convert the speed into  kilometers per hour and kilometers per minute

Since   1 mile = 1.61 kilometers

So, Speed of car = (99 ) x (1.61 )

= 159.39 kilometers per hour.

Also, 1 hour = 60 minutes

Then, Speed of car = (159.39) ÷60

= 2.6565≈2.65 kilometer per minute.

Hence, the speed is equivalent to <u>159.39 kilometers per hour </u>or <u>2.65 kilometers per minute.</u>
