Answer:
What best describes the concept of weight is the force on an object due to its mass and gravity.
Explanation:
Weight is the force with which gravity pulls a body or object towards the earth. It is a physical unit that involves both the force of gravity and the mass that an object has.
In general, the terms mass and weight are different, being the mass a characteristic of the body -without influence of other factors- and the weight is the force with which the gravity pushes the mass of that same body.
Regarding the other options:
- <em>The amount of space an object takes up
, corresponds to the volume of a body.</em>
- <em>The amount of matter in an object
, corresponds to the mass.</em>
- <em>The force on an object due to its speed and location, is related to the movement of a body.</em>
Answer:
1 million years
Explanation:
The half life of a radioactive isotope refers to the time it takes for the radioactive isotope to decay to half of its original amount.
The half life of a radioactive isotope is independent of the amount of starting material. Hence, whether the amount of starting material is small or large, the half life of the substance remains the same.
Hence the half life of 2 green marbles and 500,000 green marbles is 1 million years.
The northern slope will have the least precipitation if winds blow against a mountain from the south.
<h3>What is Slope?</h3>
This is referred to as the degree of steepness on a surface such as rocky areas etc.
When wind blows on the southern part of a mountains, it gets stuck which is why the northern slope have the least precipitation.

<h2><u>Answer:</u></h2>
The correct answer is A) 1.04 mol Cu
{65.8 g / 63.55 g/mol}
= 1.04 mol Cu
Explanation:
In 63.55 g of copper metal there are 1 m
o
l of C
u atoms. By dividing the mass of Cu and molar mass, we can easily get the number of moles.
4/325 = 2/unknown temperature
unknown temperature= 2/(4/325)=162.5k
