The downhill flow of soil and rock resulting from gravity best describes mass movement.
Answer:
60000J
Explanation:
Given parameters:
Mass of car = 1200kg
Speed = 10m/s
Unknown:
Kinetic energy = ?
Solution:
The kinetic energy is given as:
Kinetic energy = 
m v²
Now insert the parameters and solve;
m is the mass
v is the velocity
Kinetic energy = x 1200 x 10² = 60000J
B. False
When the maximum amount of solute has been dissolved in a given amount of solvent, we say that the solution is saturated with solute.
Answer:
Molarity = 0.79 M
Explanation:
Given data:
Mass of KNO₂ = 67 g
Volume of solution = 1 L
Molarity of solution = ?
Solution:
First of all we will calculate the number of moles.
<em>Number of moles = mass/ molar mass</em>
Number of moles = 67 g / 85.10379 g/mol
Number of moles = 0.79 mol
Molarity:
Molarity = number of moles / volume in L
Molarity = 0.79 mol/1 L
Molarity = 0.79 M
Answer:
Pollination is the act of transferring pollen grains from the male anther of a flower to the female stigma. The goal of every living organism, including plants, is to create offspring for the next generation. One of the ways that plants can produce offspring is by making seeds.
