Answer:
The time of flight of the ball is 1.06 seconds.
Explanation:
Given 
Also, 
Let us say the velocity in the x-direction is 
and in the y-direction is 
. And acceleration in the x-direction is 
and in the y-direction is 
.
Also, 
is distance covered in x and y direction respectively. And 
is the time taken by the ball to hit the backboard.
We can write 
. Where 
is velocity of ball.
Now,
Also,
.
Plugging this value in
So, the time of flight of the ball is 1.06 seconds.
Answer:
B.Ionizing radiation is the correct answer.
Explanation:
Ionizing radiation has sufficient energy that it can convert atoms and molecules into ions.
It has a sufficient amount of energy that it can separate tightly confined electrons from the orbit of an atom and causing that atom to become ionized.
D is the answer. Bc the pointy
In naming covalent compound (binary) based in IUPAC naming, we have 4 rules to be followed:
1. The first element of the formula will use the normal name of the given element. for example: CO2 ( Carbon Dioxide), Carbon is the element name of the first element of the formula.
2. The second element is named as if they are treated like an anion but put in mind that these are no ions in a covalent compound but we put -ide on the second element as if it is an anion.
3. Prefixes are used to indicate the number of atom of the elements in the compound. for example: mono- 1 atom, di- 2atoms, tri- 3 atoms and etc
4. Prefix "mono"is never used in naming the first element. For example: Carbon dioxide, there should be no monocarbon dioxide.
