Answer:
The specific latent heat of a substance is the amount of energy required to change the state of one kilo of the substance without change in it temperature.The latent heat of vaporization or evaporation is the heat given to some mass to convert if from the liquid to the vapor phase.
It depends on how much force there both putting on the box but because it does say the correct answer is C.
Answer:
so nothing can fly through it
Explanation:
bghh
Answer:
By applying a force of one Newton, one can hold a body of mass of 102 gram.
Explanation:
- Force is the pull or push of an object. It can be mathematically measured as, F= m* g.
where, F= force in newton
m= mass in kg
g= acceleration due to gravity ( )
F= m* 9.8
or, m= = 0.102 kg
or, m= 102 gram.
- Hence, 102 gram mass can be hold by one Newton force.
1. Answer;
Natural motion and violent motion
Explanation;
-Natural motion is the motion arising from the nature of an object. This motion does not require an external cause in order to occur. For example: Heavy bodies naturally move toward the center of the earth, therefore falling is a natural motion.
- Natural motion was determined by the nature of the object and how much of the four classical elements it contained. Violent motion is caused by external forces applied to the object.
2. Answer;
Natural motion
Explanation;
Natural motions are those motions that objects naturally did: objects on earth fell towards the center of the earth. Heavenly objects naturally moved in circles. Additionally, heavy bodies naturally move toward the center of the earth, therefore falling is a natural motion. The natural motion of objects is one of the characteristics of an object.
3. Answer;
To assume that Earth and the other planets rotate around the sun
Explanation;
-Copernicus proposed an alternative theory--that the Earth was a planet orbiting the Sun, and that all planets moved in circles, one inside the other. Mercury and Venus had the smallest circles, smaller than that of the Earth, and therefore their position in the sky was always near the Sun's.
-That made it easy to estimate their distances from the Sun in terms of the Earth-Sun distance.
