Which of the following best describes weight?
hodyreva [135]

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>

Write the quantities 3 x 10^-4 cm and 3 x 10^4 km in ordinary notation
Goshia [24]
To write quantities in ordinary notation, you need to notice the power of the exponent.
If the power is positive, then you move the decimal point to the right by the number the power in exponent tells you.
If the power is negative, then you move the decimal point to the left by the number the power in exponent tells you.

We have:
3 x 10^-4 : the power of exponent is negative, therefore, we will move the decimal point 4 places to the left.
3 x 10^-4 = 0.0003 km

3 x 10^4 : he power of exponent is positive, therefore, we will move the decimal point 4 places to the right.
3 x 10^4 = 30000 km

Andrew [12]

Answer: 12.18 u

Explanation: The average atomic mass of an element is calculated by taking the weighted average of the atomic masses of its stable isotopes.

In other words, each stable isotope will contribute to the average mass of the element proportionally to its abundance.

Fill in the blank:
Roman55 [17]

Answer:

Weathering, Erosion

Explanation:

Plants and animals can be agents of mechanical weathering. The seed of a tree may sprout in soil that has collected in a cracked rock. As the roots grow, they widen the cracks, eventually breaking the rock into pieces. Over time, trees can break apart even large rocks.

Tree root systems have a handful of large roots that branch out into a network of smaller roots that often extend out far beyond their branches do. These root systems prevent erosion by holding the soil in place and improving drainage which helps water get absorbed into the soil instead of just running over the top.

Hope this helps

All the love, Ya boi Fraser :)
