1. What are three examples of forces?
Answer: Gravitational force.
Electric force.
Magnetic force.
Nuclear force.
Frictional force.
Explanation: I learned when I had science class.
What do the words "distance", "force", and "work" have to do with each other?
Answer: the force applied to the object and the distance the object move Work can be calculated with this equation: Work equals Force x Distance.

Explanation:
Omar wrote a hypothesis about batteries called dry cells. If more dry cells are connected end to end, a light bulb will work longer because there is more energy available. What are the variables in his hypothesis? The independent variable is the number of dry cells, and the dependent variable is the length of time the bulb works. The independent variable is the length of time the bulb works, and the dependent variable is the number of dry cells. The independent variable is the number of dry cells, and the dependent variable is the amount of energy available. The independent variable is the amount of energy available, and the dependent variable is the number of dry cells.
Answer:
The independent variable is the number of dry cells and the dependent variable is the time the bulb works.
Explanation:
In this exercise, you are asked to analyze the variables derived from Ómar's hypotypeis
"If more dry cells are connected end-to-end, a light bulb will work longer because more energy is available."
In this hypothesis, the independent variable that is controlled by the researcher is the number of batteries to be connected in series.
The dependent variable that is measured by the researcher is how long the bulbs last.
When reviewing the different answers, the correct one is:
The independent variable is the number of dry cells and the dependent variable is the time the bulb works.

In an aqueous solution where the H+ concentration is 1 x 10-6 M, the OH concentration must be:
A. 14 x 10-6 M
B. 1 x 10-6 M
C. 1 x 10-7 M
D. 1x 10-8 M
E. 14 x 10-8 M
Answer:
D. 1×10⁻⁸ M
Explanation:
[H⁺] [OH⁻] = 10⁻¹⁴
(1×10⁻⁶) [OH⁻] = 10⁻¹⁴
[OH⁻] = 1×10⁻⁸
The concentration of hydroxyl ion will be [tex]10^{-8}[/tex]M.
What is concentration?The amount of a chemical substance in a mixture is expressed by the substance's concentration.
Calculation of concentration.
Given data:
Concentration of H+ = 1 x [tex]10^{-6}[/tex] M.
It is known that,
[[tex]H^{+}[/tex]][[tex]OH^{-}[/tex]] = [tex]10^{-14}[/tex]M
Now, put the value of concentration of [[tex]H^{+}[/tex]] in above equation.
[1× [tex]10^{-6}[/tex]][[tex]OH^{-}[/tex]] = [tex]10^{-14}[/tex]M
[[tex]OH^{-}[/tex]] = [tex]10^{-14}[/tex] / [1× [tex]10^{-6}[/tex]]M
[[tex]OH^{-}[/tex]] = [tex]10^{-8}[/tex]M
Therefore, the concentration of hydroxyl ion will be [tex]10^{-8}[/tex]M.
Hence, the correct answer will be an option (D).

A car starts from rest and accelerates uniformly over a time of 5.21 seconds for a distance of 110 m. Determine the acceleration of the car.
Answer: 8.1m/s^2
Explanation:
For this question, in order to solve it, we have to use the second equation of motion which will be:
s = ut + 1/2at^2
where,
u = initial velocity
v = final velocity
t = time
a = acceleration
Since u = 0, then
a = 2s/t^2
a = 2 × 110/5.21^2
a = 220/27.1441
a = 8.1m/s^2

Calculate the following sum, and express the answer in meters. Follow the rules for significant figures.
(25.873 km) + (1024 m) + (3.0 cm) =
Answer:
26897.3 m
Explanation:
1 km = 1000 m
1 cm = 0.01 m
so the calculation will be
25873 m + 1024 m + 0.03 m= 26897.3 m
The sum of the given expression (25.873 kilometers ) + (1024 meters ) + (3.0 centimeters) would be 26897.0 meters.
What are significant figures?In positional notation, significant figures refer to the digits in a number that is trustworthy and required to denote the amount of something, also known as the significant digits, precision, or resolution.
As given in the problem we have to Calculate the following sum and express the answer in meters, by Following the rules for significant figures,
(25.873 kilometers ) + (1024 meters ) + (3.0 centimeters)
1 kilometers = 1000 meters
1 meter =100 centimeters
(25.873 ×1000×100) + (1024×100 ) + (3.0 centimeters)
= 26897.03 centimeters
Thus ,the sum of the given expression (25.873 kilometers ) + (1024 meters ) + (3.0 centimeters) would be 26897.0 meters.

A toy car with mass of 3.0kg is push along the table .If the net force on the book is 15.0N what is the toy car's accelaration?
Answer:
a = 5
Explanation:
F = M × A
15 = 3 × a
a = 15 / 3
a = 5
This is only if the toy can is pushing the book or smth coz the question looks incomplete...?
Answer:
5 m/s^2
Explanation:
Realize that Newton's Second Law explains that the net force is equal to the mass mulitplied by the acceleration, or in simple terms, F=ma. In the problem, the force is 15 newtons, and the mass is 3 kg. Substiting and dividing, we get 5 m/s^2 (5 meters per second squared).

An object has a mass of 14 grams and a density of 7 g/mL. When placed in water it sinks. What is the
Volume of water displaced?
-28g
-14ml
-98ml
-2ml
Answer:
The answer is 2 mLExplanation:
The volume of a substance when given the density and mass can be found by using the formula
[tex]volume = \frac{mass}{density} \\[/tex]
From the question
mass = 14 g
density = 7 g/mL
So we have
[tex]volume = \frac{14}{7} \\ [/tex]
