How Buoyancy force on an object is related to the weight of liquid it displaces?
The buoyancy force (B) is equal to the weight (W) of the fluid that a body in that fluid displaces. Fluid pressure increases with depth because of the (gravitational) weight of the fluid above. This increasing pressure applies a force on a submerged object that increases with depth. The result is buoyancy
Why do you think that the particles of a suspension settle out but the particles of a colloid do not? Explain your reasoning.
Answer:
a collaid make more particles
Explanation:
Hardness refers to the strength of the forces holding atoms together in a solid mineral. The Mohs scale will tell how easily a mineral can be scratched. It has a range from 1 to 10. Diamonds are a 10 on the Mohs scale. They are the hardest minerals in the world. The color of a mineral is often easy to identify. Many minerals are found in a range of colors. This is true for diamonds also. They can be yellow, brown, blue, green, orange, purple, black, pink, red, or colorless. Colored diamonds have impurities that cause them to change colors. Colorless diamonds, however, are very pure. Luster refers to how a mineral looks when it reflects light. A minerals luster could be metallic, dull, pearly, or adamantine. Diamonds have adamantine luster–their brilliant sparkle. Streak refers to the color of the powder left by a mineral. Streak is often found after a mineral is scratched on a porcelain tile. The color of the streak left on the tile helps to identify the mineral. The streak of a diamond is white.
Paragraph 5 of this passage mainly tells about

This image shows an overhead view of Atlanta’s buildings, structures, and surrounding areas and a heat map of the area. What is the most likely reason for the high temperature in the regions indicated in dark red? two maps of Atlanta, one showing an overhead view of Atlanta's buildings and structures and other showing the heat levels in the area Atlanta’s roads and buildings absorb more of the Sun’s radiation, causing higher temperatures than in surrounding regions. Atlanta’s trees and forests absorb more of the Sun’s radiation, causing higher temperatures than in surrounding regions. The rural areas around Atlanta absorb more heat than the urban areas, causing an overall increase in the city’s temperatures.

Explanation:
just do it
define acceleration
Answer:
In mechanics, acceleration is the rate of change of the velocity of an object with respect to time. Accelerations are vector quantities. The orientation of an object's acceleration is given by the orientation of the net force acting on that object

You measure the mass of an apple using a balance. You get these three measurements:
Trial 1: 167.0 g
Trial 2: 166.9 g
Trial 3: 167.2 g
You know that the true mass of the apple is 172 g. Describe your results in terms of precision and accuracy. Explain your answer.
