Answer:

The Correct Answer is

The ozone protects us from the suns harmful rays

Explanation:

The ozone layer serves as transparent protection and preserves us from dangerous ultraviolet (UV) radiation from the day-star.
Long-term vulnerability to large levels of ultraviolet (UV) radiation can seriously harm most creatures, flowers, and microorganisms, so the ozone layer preserves all living beings on Earth.

What is climate change? How is it caused

OleMash [197]

climate change is a change in climate in the Earth 's normal weather patterns for different climates. it normally changes little by little over the years.the earth is cooler and warming .now it's getting warmer. this phenomenon is also known by as globall warming.it's causes are:

1.energy uses

2.agriculture and land use 3.Transport 4.Industries 5.Growing demands for food and water

A greenhouses is made from glass or clear plastic. It is useful for growing plants in winter in cooler climates.

If the temperature rises by 9. 9 degrees, what is the corresponding temperature increase in degrees celsius?

Yanka [14]

Main Answer:

Assume that the temperature rises by 9.9 F

Initial Temperatures will be C1, F1

Final temperatures will be C2, F1 + 9.9

The relation between celsius and fahrenheit temperature is as follows:

C = 5/9(F - 32)

Increase in temperature in celsius will be

C2 - C1 = F2 - F1

C2 - C1 = 5/9 ( F1 +9.9 -32) - 5/9 ( F1 -32)

C2 - C1 = 5/9 ( F1 +9.9 -32 - F1 +32)

C2 - C1 = 5/9 (9.9)

C2 - C1 = 5.5C

Explanation:

What is temperature?

Temperature is defined as the degree of coldness or hotness of an object or a substance. Generally, it is measured in various temperature scales. They are celsius, fahrenheit, kelvin.

If the pressure of a substance is increased during a boiling process, will the temperature also increase, or will it remain cons

7nadin3 [17]

Answer:

on increasing pressure, temperature will also increase.

Explanation:

Considering the ideal gas equation as:

$PV=nRT$

where,

P is the pressure

V is the volume

n is the number of moles

T is the temperature

R is Gas constant having value = 0.0821 L.atm/K.mol

Thus, at constant volume and number of moles, Pressure of the gas is directly proportional to the temperature of the gas.

P ∝ T

Also,

Also, using Gay-Lussac's law,

$\frac {P_1}{T_1}=\frac {P_2}{T_2}$

Thus, on increasing pressure, temperature will also increase.

A 0.017-kg acorn falls from a position in an oak tree that is 18.5 meters above the ground.

Genrish500 [490]

Answer:

Velocity= 19.05 m/s

Kinetic energy= 3.08 J

Explanation:

The corn possess potential energy. Feom law of conservation of energy, all the potential eneegy will be converted to kinetic energy, with negligible friction.

Potential energy, PE= kinetic energy, KE

Potential energy is given by mgh while kinetic energy is given by $0.5mv^{2}$

Equating

$mgh=0.5mv^{2}$

Making v the subject of the formula then

$v=\sqrt {2gh}$

Substituting 9.81 m/s2 for g and 18.5 m for h then the velocity will be

$v=\sqrt {2\times 9.81\times 18.5}=19.0517715711689\ m/s\\v\approx 19.05\ m/s$

To get the kinetic eneegy, since PE=KE AND KE is

$KE=0.5mv^{2}$

Substituting v with 19.05 and m with 0.017 kg we have

$0.5\times 0.017\times 19.05^{2}=3.08467125/ J\approx 3.08 J$

This can also be achieved by mgh since PE=KE hence 0.17*9.81*18.5=3.085245 J and the results are slightly different due to small energy losses and rounding off of values.
