Humans are a living compound that contains hydrogenÂ
A 8 g object displaces 50 mL of water. What is its specific gravity?
Answers
The specific of gravity is 0.16
Hope this helps :)
Answer:
he is right it is 0.16
Explanation:
What is the relationship between height and energy ?
Answers
Since the gravitational potential energy of an object is directly proportional to its height above the zero position, a doubling of the height will result in a doubling of the gravitational potential energy. A tripling of the height will result in a tripling of the gravitational potential energy.
What would happen to temperatures on earth the suns heat were distributed throughout the atmosphere
Answers
If the sun's heat is distributed uniformly throughout the atmosphere, this will ensure that each point on the earth gets a moderate level of heat and temperature in these locations will be within the acceptable level. If the sun's heat is concentrated in one part of the atmosphere, the location that correspond to the point of concentration will receive enormous amount of heat from the sun, which will shoot up the temperature of that location. This will leads to all manner of disruptions in the ecosystem that is found in that location.
For example, California's water cycle was on hold because we did not have any rain. The weather has been dry warm, so all of the water is being evaporated, but never reaching the precipitation phase of the cycle.
In a lab, Brett is mixing hydrochloric acid with water. This is an extremely explosive mixture that releases heat. What kind of reaction is this, endothermic or exothermic reaction
Answers
The definition of an exothermic reaction is releasing heat and endothermic reaction is an absorption of heat.
This reaction is exothermic because it releases heat and doesn't absorb it when mixing hydrochloric acid with water.
Exothermic because you are releasing heat not absorbing.
Sandstone and slate are used for building, but these rocks have different properties. Which rock would you use for a use for roof? Which would you use the walls of a building? Explain. Please help ty
Answers
Slate is a natural stone that splits easily into thin sheets. A sheet of slate can be cut into shingles that provide excellent protection against rain and melting snow, and it is very dense and hard, therefore it is highly resistant to being reshaped or damaged by weather. Sandstone can be broken into flat layers that can then be broken into squared-off chances. These pieces of squared-off sandstone serve well in construction of walls for buildings.
