Answer:
d. There is no charge
Step-by-step explanation:
An atom of this nature with equal number of protons and neutrons will have no charge on them.
- Protons are the positively charged particles in an atom
- Electrons are negatively charged.
- Neutrons carry no charges.
In an atom, when there is an imbalance between the number of protons and electrons, they become charged.
When the number of protons and electrons are the same, then, the atom becomes uncharged.
Charge = Number of protons - Number of electrons
Number of protons = 6
Number of electrons = 6
Charge = 6 - 6 = 0
So, the atom will have no charge on it.
Answer:
56
Step-by-step explanation:
I assume each person in the group must have 1 pencil AND 1 eraser each.
Since you have more pencils than erasers, then the limiting factor is the number of erasers. So a group of 56 people will have 1 pencil And 1 eraser and Clare will have 24 pencils left over (assuming Clare has her own pencil and eraser - if not then the group size is 55 assuming Clare is not in the group)
sorry if it's too confusing
Answer: 8.3 minutes
Step-by-step explanation:
1 mile is to 1.60934km so 93 million miles is:
= 93 * 1.609
= 149,637,000 km
Travelling at 300,000 km per second, the number of seconds it takes is:
= 149,637,000/300,000
= 498.79 secs
In minutes this is:
= 498.79/60
= 8.3 minutes
Y = kx, k being a constant
--------------------------------------
Find k :
--------------------------------------
When x = 12, y = 3
3 = k(12)
k = 3/12
k = 1/4
Equation : y = 1/4 x
--------------------------------------
Find y when x = 20:
--------------------------------------
When x = 20,
y = 1/4 (20)
y = 5
--------------------------------------
Answer: y = 5
--------------------------------------
The vertex would be (-5, 7).
The parabola would open downwards because of the negative sign at the very beginning of the equation. If that negative sign wasn't there, it would open upwards.
Don't think clever or anything. I just used a simple graphing calculator, and most classes encourage the use of these calculators.
