Answer:
B, the car travels around a circular track at 30 m.
Explanation:
<h2>
Answer:</h2>
38.14Ω
<h2>
Explanation:</h2>
Let's solve this question using Ohm's law which states that the current (I) flowing through a conductor is directly proportional to the potential difference or voltage (V) across it. Mathematically;
V = I R -------------------(i)
<em>Where</em>;
R is the constant of proportionality called resistance of the conductor and is measured in Ohms (Ω)
<em>From the question;</em>
V = 18.5V
I = 0.485A
<em>Substitute these values into equation (i) as follows;</em>
18.5 = 0.485 x R
<em>Solve for R;</em>
R = 18.5 / 0.485
R = 38.14Ω
Therefore the resistance of the bulb is 38.14Ω
Answer:
Elements- made of one type of atom
Can not be broken down
Compounds
Represented by formulas
Can be chemically broken down
Made of two or more types of atoms
Explanation:
An element is a chemical substance which cannot be further broken down into other chemical substances. An element is composed of only one type of atom. Examples of elements include, sodium, magnesium, gold, silver etc.
Compounds are formed when one or more elements combine in a definite ratio. Compounds are represented by chemical formulas which show the number of combining atoms e.g CaCO3, HF, etc. Some compounds can be broken down chemically.

33. The 1.5kg owl is now soaring at 20m/s. What is the owl’s KE?
a. Step 1: Formula <u>½mv²</u>
b. Step 2: Data m = <u>1</u><u>.</u><u>5</u><u> </u><u>kg</u>, v = <u>2</u><u>0</u><u> </u><u>m</u><u>/</u><u>s</u>
c. Step 3: Solve
KE = (1/2)(<u>1</u><u>.</u><u>5</u>)(<u>2</u><u>0</u>)² = <u>3</u><u>0</u><u>0</u><u> </u><u>J</u>
I believe it is the word is equilibrium because your body must kick on other systems if one is falling behind. Ex. You are cold so you shiver to keep warm.
