Answer:
ieces A and B must also have the same type of charges
Explanation:
In electrostatics, charges of the same sign repel and charges of different signs attract.
If we apply this to our case, we have that part A and C repel each other, therefore they have the same type of charge.
Also part A and C repel each other, therefore they have the same type of charge.
If we use the transitive property of mathematics, pieces A and B must also have the same type of charges
Answer:
Both
Explanation:
The lithosphere is part of both the crust and the mantle.
It is the surface layer of the earth and also the most rigid layer. It is formed by the crust and the outermost part of the mantle. It is divided into two types: continental lithosphere and oceanic lithosphere.
The oceanic lithosphere has an approximate thickness of 50 - 100km, and the continental olithosphere of 40 - 200km.
Conduction: someone burning their hand by placing their hand on a hot stove.
Convection: Food cooking in an oven.
Radiation: The heat we feel from the sun.
Gravity is 9.81m/s^2 on earth F=m×g
100N=(x)kg×9.81m/s^2
x=10.19kg or more than 22lbs
Given:
rate of effusion of Helium = 6 hours
Data needed:
Molar mass of hydrogen gas = 2 g/mol
Molar mass of helium gas = 4 g/mol
Assume:
Constant conditions such as temperature and pressure.
Required:
rate of effusion of Hydrogen gas
Solution:
To solve the problem, we can use the formula:
rate of effusion of A/ rate of effusion of B = (molar mass of B/molar mass of A)^1/2
substituting values,
rate of effusion of hydrogen gas/ 6 hours = (4 g/mol/2 g/mol)^1/2
rate of effusion of hydrogen gas = 8.5 hours
