When the earth is closest to the sun it is said to be in perihelion position.
Answer:
the pressure exerted by the object is 392,000 N/m²
Explanation:
Given;
mass of the object, m = 8 kg
area of your finger, A = 2 cm² = 2.0 x 10⁻⁴ m²
acceleration due to gravity, g = 9.8 m/s²
The pressure exerted by the object is calculated as;
Therefore, the pressure exerted by the object is 392,000 N/m²
Answer:
Most of materia isnt life.
Explanation:
The living organisms (life) aren't the most abundant thing in universe.
Hydrogen and helium are present in everywhere, but life isn't.
There is no reason to think because we have a lot of a thing, the life must be made for this thing.
The organic life just can exists because some mysterious properties about carbon, that is the basic foundation of life, carbon is a special element, why? We don't know, actually, it's a huge problem for science discover why the carbon can makes life be possible and other elements can't. But we know is this element that makes life possible.
So, note there isn't relation about the quantity of a material in Universe and the life constituition. In addition, look around, organic materials are very rare in Universe, Earth is one in lots of places and in most of this places there isn't sign of life.
Even in Earth the life looks abundant, in Universe it isn't, the same way in Universe the Hydrogen and Helium are abudant, in Earth isn't soo.
Answer:
0.882 m/s average velocity and 1.71 m/s average speed
Explanation:
The dog travels a total of 35 m west and 110 m east.
110-35 = 75 m east of the starting position. Since velocity is a vector you must consider its first and final position and not the total distance traveled.
75 m / 85 s = 0.882 m/s average velocity
Speed is not concerned with direction so we instead add the total distance traveled which is 35+110 = 145 m. We then perform the same operation as before and divide by the time it took to run this distance.
145 m / 85 s = 1.71 m/s average speed
Energy from the sun is referred to as solar energy.
So energy from the sun is solar energy.
hope it helps!!!
