Answer:
"Narrow the focus of research question"
Explanation:
O Narrow the focus of research question
This is good! You can still use your question, but focus in on something so you have a proper research project.
O Add another research question
Would adding another question to an already broad question help? No.
O Use the very first source you find for your project
If your question is too broad, you should not use whatever you see first as it may be incorrect or does not answer the question
O Change the scope of your project
You could, but if you have a set scope for your project (a) you might not be able to change it (b) you don't need to restart
Have a nice day!
I hope this is what you are looking for, but if not - comment! I will edit and update my answer accordingly. (ノ^∇^)

Answer:
When the image distance is positive, the image is on the same side of the mirror as the object, and it is real and inverted. When the image distance is negative, the image is behind the mirror, so the image is virtual and upright.
Explanation:
Answer:
Na⁺
Explanation:
In the given atom:
Number of protons = 11
Number of neutrons = 12
So, the number of electrons = 10
The number of protons within an atom is used to determine the kind of atom we have been given.
Since the number of protons is the same as the atomic number, here the atomic number is 11 and this is Sodium .
In this sodium atom, the number of protons is more than the number of electrons;
Charge = number of protons - number of electrons = 11 - 10 = +1
So, we have a Na⁺
Explanation:
Spring is stretched by force f to distance
"X"
now here by force balance we can say
f = kx
k = !
now here we will we say that energy stored in the spring will convert into kinetic energy
kx² = mv²
(x² = mv²
now solving above equation we will have
PART 2)
now for half of the extension again we can use energy conservation
ka²-k(x/2)² = 1 {mv²
¾fx=mv²
now the speed is given as
3 fr 4m V=
Answer:
B. Nuclear to Electrical
Explanation:
Atoms are split at power plants to create electricity. The energy conversion in this process is from nuclear to electrical energy.
- When atoms are split, nuclear energy is released.
- Some part of the mass of the atom is converted to energy.
- The nuclear energy released is expressed as heat energy.
- This energy is used to heat water in boilers when produces steam that are used to drive the movement of turbines.
- This in turn generates electricity.
