Answer:c
Explanation:
A valley will be carved out due to erosion.
Answer:
The sentences which are made by the given sentences are as :
Wind speeds are below 38 miles per hour, this feature represents the tropical depression.
Explanation:
Here in the question it has been mentioned to form the sentences with the given one:
- Wind speeds are below 38 miles per hour, this feature represents the tropical depression.
- A tropical disturbance leads to an array of clouds which are disorganized also there are thunderstorms with no rotation or little rotation with it.
- When the winds are blowing at a speed of 38 and 74 miles per hour then it is called as a tropical disturbance.
- 74 miles per hour should be the blowing speed of storm in order to consider it to be a Hurricane.
- When the storm reaches a tropical storm stage it gets its name.
- All of the storms which get occurred from time to time, among them half or even all get converted into a Hurricane.
These are the sentences which are made by exploring the whole process and by which a storm becomes a Hurricane.
Answer:
The number of copper atoms 12.405 ×10²³ atoms.
The number of silver atoms 13.13 ×10²³ atoms.
Beaker B have large number of atoms.
Explanation:
Given data:
In beaker A
Number of moles of copper = 2.06 mol
Number of atoms of copper = ?
In beaker B
Mass of silver = 222 g
Number of atoms of silver = ?
Solution:
For beaker A.
we will solve this problem by using Avogadro number.
The number 6.022×10²³ is called Avogadro number and it is the number of atoms in one mole of substance.
While we have to find the copper atoms in 2.06 moles.
So,
63.546 g = 1 mole = 6.022×10²³ atoms
For 2.06 moles.
2.06 × 6.022×10²³ atoms
The number of copper atoms 12.405 ×10²³ atoms.
For beaker B:
107.87 g = 1 mole = 6.022×10²³ atoms
For 222 g
222 g / 101.87 g/mol = 2.18 moles
2.18 mol × 6.022×10²³ atoms = 13.13 ×10²³ atoms
Astatine. Because it has the smaller shell of electrons. I believe
Potential energy is not in motion, which means the roller coaster wouldn't be moving. do therefore it is kenetic energy because that means movement energy. hope this helps
