The answer is A
Explanation: the conservation of matter means that the mass stays the same
A compound is the substances that are formed by combining two are more chemical elements. A mixture is a substance created from two or more matter that can be separate with the help of physical methods. ... Mainly pure water is part of the compound. Mixtures fall under impure water.
Hope this helps!
Have a great day!
You cant skip nothing. All the lessons are important! Sorry about you free time :/
Emf e = 11
r 1 = 3.0
r 2 = 3.0
r 3 = ?
The two in parallel are equivalent to 3 • 3/6 = 1.5 Ω
To have 2.4 volts across them, the current is I = 2.4/1.5 = 1.6 amps. and the unknown R = (11–2.4) / 1.6 = 5.375 Ω or 5.4 Ω
The factors which are affected will be based on the distance or range between the charged objects A and B
<u>Explanation:</u>
<u>Definition:</u>
- The force, F among the two-point size charges A and B are divided by a range r is given by Coulomb formula.
F=9x10^9 AB/r²
<u>Factors:</u>
- If the range among them is doubled the force will be decreased to 1/4 of the initial value. And if the range is split, the force will be four times.
- If the range among them is tripled, the force will be decreased to 1/9 of the initial value. If the range is decreased to one-third of the new value, the force will rise to Nine times the initial value.
