Answer:
a. Chemical formula
Explanation:
A notation that shows which elements, and how many of each type a compound contains is a chemical formula.
Basically, a chemical formula helps scientists to show or illustrate the type and number of atoms present in a particular molecule or compound by using numerical subscript, ions and atomic symbol of a chemical element.
This ultimately implies that, a chemical formula is used to describe or denote the exact amount of atoms that make up a molecule or compound.
<em>Some examples of a chemical formula are;</em>
Water =
Sodium Hydroxide =
Hydrochloric acid =
Carbon II oxide =
For a lightbulb, you turn electrical energy into heat and light energy. For a battery, you turn chemical energy into electrical energy and light energy? I could only go that far. Sorry :(
Answer:
Explanation:
position
y(t) = 2.80t + 0.61t³
velocity is the derivative of position
v(t) = 2.80 + 1.83t²
acceleration is the derivative of velocity
a(t) = 3.66t
F = ma = 5.50(3.66(4.10)) = 82.533 N
which should be rounded to no more than three significant digits and arguably only two due to the 0.61 factor.
F = 82.5 N or 83 N
Yes the units are Newtons, cannot tell what your system will accept. May not want the units at all.
Answer: 4 times grease
Explanation: Force F= C · q1·q2/r². C = Coulomb's constant.
If charges double you have 2q1 and 2q2.
