Answer:
The weight of a dog is 120N.
Explanation:
Converting kg to N, you have to multiply it by 10 :
1 kg = 10 N
12 kg = 12 × 10 N
= 120N
Or you could use the formula of force, F = m×g where g is the gravity of Earth. You can use this formula because both <em>W</em><em>e</em><em>i</em><em>g</em><em>h</em><em>t</em><em> </em>and <em>F</em><em>o</em><em>r</em><em>c</em><em>e</em><em> </em>have the same symbol, Newton :
m = 12 kg
g = 10 m/s²
F = 12 × 10
= 120 N
Hello! The nontoxic, nonflammable chemicals containing atoms of carbon, chlorine, and fluorine that have created a hole in the ozone layer are the Chlorofluorocarbons (CFCs)
These are compounds developed and improved by Thomas Midgley in the late 1920s. They were used as refrigerants and aerosol propellants.
These compounds created a hole in the ozone layer by the following reactions:
CCl₃F → CCl₂F· + Cl· (In the presence of light. Radical Reaction)
Cl· + O₃ → ClO + O₂
ClO + O₃ → Cl· + O₂
The last 2 reactions can repeat in a radical mechanism and explain why these compounds are so harmful to the ozone layer.
The answer is B.) Able to travel through a vacuum!! <3
Answer:15,883.63 KJ
Explanation:
Given
Power=400 W
Freezing compartment temperature is 273 K
Outside air Temperature=306 K
Time =80 minutes
Energy Required to deliver 400 w power in 80 minutes
E=1920 KJ
and we know COP of refrigerator is given by
Therefore 15,883.63 KJ is removed in 80 minutes
Answer:
Renewable energy minimizes carbon pollution and has a much lower impact on our environment. And it's having its moment in the sun. "Giving more New Yorkers access to renewable energy can allow them to reduce their own energy bills while reducing stress on the grid and demand for fossil fuel power.
