How do greenhouse gases such as CO2 and N2O contribute to an increase in Earth’s atmospheric temperature?

Answer:

By trapping the excess heat in the Earth's Atmosphere

Explanation:

When Sun light and other radiations fall on Earth a part of it is reflected back. Greenhouse gases such as CO₂ andN₂O traps the reflected heat and maintain the temperature on Earth. This is required to maintain a temperature that is suitable for survival of life. If these gases are not present in the atmosphere, Earth will be too cold to live. At the same time if these gases are present in large amount, they will trap more heat and thus increase the overall temperature of the Earth resulting in Global Warming.

Due to various reasons the amount of such gases has been increasing in our atmosphere in turn increasing Earth's temperature.

CO2 and N2O keep the energy that gets to Earth from the sun inside the atmosphere. Without greenhouse gases, our planet would be too cold. But due to the recent increase in greenhouse gases, more energy released from the sun is contained in the Earth, heating it up.

kiruha [24]

Answer:

4565 meters

Explanation:

W = V²/R

25 = (25)²/R

R = 25 ohm

R = (pl)/A

R =  \frac{pl}{2\pi( \frac{d}{2} )}

25 =  \frac{( 2.82\times  {10}^{ - 8}  \times l)}{2\pi (\frac{1.60 \times  {10}^{ - 6} }{2}) }

l = 4565 meters approximately

Naily [24]

Answer:

1. supernova

2. bubble

3. atomic hydrogen cloud

4. molecular cloud

Explanation:

Supernova involves the bright explosion of a star when this happens it returns gas and new elements in to space. The expelled hot gas from the explosion forms a bubble and starts expanding in size. As this bubble cools, it merges merges with other interstellar gas to form an atomic hydrogen cloud. The atomic hydrogen cloud cools further to form a molecular cloud where another star formation begins to occur.

An object was released from rest at height of 1.65 m with respect to ground. Determine the time it takes the object to reach the
vivado [14]

Answer:

The time taken by the object to reach the ground is 0.58 seconds.

Explanation:

Given that,

An object was released from rest at height of 1.65 m with respect to ground. We need to find the time taken by the object to reach the ground. Initial speed of the object is 0 as it is at rest. It will move downward under the action of gravity such that, the distance covered by the object is given by :

d=ut+\dfrac{1}{2}gt^2

d=\dfrac{1}{2}gt^2

t=\sqrt{\dfrac{2d}{g}}

t=\sqrt{\dfrac{2\times 1.65}{9.8}}

t = 0.58 seconds

So, the time taken by the object to reach the ground is 0.58 seconds. Hence, this is the required solution.

A 1500-kg car locks its brakes and skids to a stop on a slippery horizontal road, leaving skid marks that are 15 m long. How muc
Harman [31]

Answer:

E=88200\ J

Explanation:

Given:

  • mass of car, m=1500\ kg
  • distance of skidding after the application of brakes, d=15\ m
  • coefficient of kinetic friction, \mu_k=0.4

<u>So, the energy dissipated during the skidding of car:</u>

<em>Frictional force:</em>

f=\mu_k.N

where N = normal reaction by ground on the car

f=0.4\ties 1500\times 9.8

f=5880\ N

<em>Now from the work-energy equivalence:</em>

E=f.d

E=5880\times 15

E=88200\ J is the dissipated energy.
