Percent error is a mathematical way of showing accuracy, dependent variable is what is measured and affected during the experiment, independent variable is what is changed by the researcher.
What is Percent error?Percent error is the difference between the estimated value and the actual value in comparison to the actual value of the experiment and is expressed as a percentage value. In other words, the percent error is the relative error multiplied by the number 100.
Direct relationship is a relationship between any two variables whereby both the variables increase or decrease together. Directly affect each other.
Inverse relationship is a relationship between any two variables whereby one variable increases and the other variable decreases. The variables affect each other but inversely.
An independent variable is the variable which is changed by the researcher through the experiment.
A dependent variable is the variable which is measured and affected during the experiment and it often described as being dependent on the independent variable of the experiment.

"For an object moving at a constant speed, we would expect to see a position graph with a
Explanation:
The speed of an object is given by the total distance divided by the total time taken.
The position of an object shows its location. If we draw a position- time graph for an object moving at a constant speed, it will look like the attached figure. It means that the object is moving at a steady rate. It is a straight line passing through origin.
Calcula la energía cinética de un coche de 500kg de masa que se mueve a la velocidad de 100 km/h. Pasamos la velocidad a las unidades del sistema internacional.
Responder:
192,900.64 Julios
Explicación:
La energía cinética es la energía que posee un cuerpo en virtud de su movimiento. Sea la masa del cuerpo m, su velocidad v.
Energía cinética = 1/2 mv²
Parámetros dados
masa del coche = 500 kg
velocidad = 100 km / h
La velocidad debe estar en m / s según la unidad internacional estándar. Al convertir;
100 km / h = 100 * 1000/3600 m / s
100 km / h = 27,8 m / s
velocidad del cuerpo = 27,8 m / s
Necesario
Energía cinética del coche = 1/2 * 500 * 27,8²
Energía cinética del automóvil = 1/2 * 500 * 771.6
Energía cinética del automóvil = 1/2 * 385,801.28
Energía cinética del automóvil = 192,900.64 Julios
Por lo tanto, la energía cinética del automóvil es 192,900.64 julios.

Use the formula to solve for the variable of d
v=d/t
A. d = v/t
B. d = vd
C. d = vt
D. d = t/v
a is correct
Explanation:
beacuse d is directly proportional bto velocity and the time taken
Answer:
C. d=vt
Explanation:
We are given this formula:
[tex]v=\frac{d}{t}[/tex]
and asked to solve for the variable d.
In order to solve for d, we must isolate it on one side of the equation.
d is being divided by t. The inverse of division is multiplication. Multiply both sides of the equation by t.
[tex]t*v=\frac{d}{t} *t[/tex]
[tex]t*v=d[/tex]
[tex]tv=d[/tex]
[tex]d=tv[/tex]
Due to the commutative property of multiplication, we can switch the v and the t.
[tex]d=vt[/tex]
The formula solved for d is d=vt and C is the correct answer.

A bicyclist is traveling 10 m/s with an acceleration of 6 m/s2.
How fast is the bicyclist traveling at the end of 20 seconds?
A
20 m/s
B
26 m/s
C
110 m/s
D
130 m/s
Answer:
The answer is option DExplanation:
From the question we are finding the final velocity of the bicycle
To find the final velocity given the initial velocity , acceleration and time we use the formula
v = u + at
where
v is the final velocity
u is the initial velocity
a is the acceleration
t is the time
From the question
u = 10 m/s
a = 6 m/s²
t = 20 s
Substitute the values into the above formula and solve
That's
v = 10 + 6(20)
= 10 + 120
We have the final answer as
130 m/sHope this helps you.

El profesor de Pedro mencionó en su clase que la distancia promedio de la Tierra a la Luna es de 384 000 000 metros. Ayuda a Pedro a escribir este número en notación científica
Answer:
384 000 000 en notación científica es 3.84*10⁸
Explanation:
La notación científica es una forma de representar números para simplificar la forma en que se escriben. Esta notación se utiliza para poder expresar muy fácilmente números muy grandes o muy pequeños.
Los números se escriben como un producto:
a*10ⁿ
donde:
a es un número real mayor o igual que 1 y menor que 10.n es un número entero, que recibe el nombre de exponente u orden de magnitud. Representa el número de veces que se desplaza la coma. Siempre es un número entero, positivo si se desplaza a la izquierda, negativo si se desplaza a la derecha.Para escribir el número 384 000 000 en notación científica, se realizan los siguientes pasos:
Se mueve la coma decimal hacia la izquierda tantos espacios hasta llegar a la derecha del primer dígito. En este caso la coma se encuentra al final del número.Se escribe entonces este número, que será el coeficiente a en la expresión a*10ⁿ. En este caso es el valor 3.84, donde el punto representa la coma decimal.Se escribe la base 10 con el exponente igual a la cantidad de espacios que se mueve la coma. Este es un número positivo porque la coma se desplaza a la izquierda. Entoces, como la coma decimal se mueve 8 lugares, n=8Entonces, 384 000 000 en notación científica es 3.84*10⁸

A water holding tank measures 85 m long, 55 m wide, and 9 m deep. Traces of mercury have been found in the tank, with a concen- tration of 65 mg/L.
What is the total mass of mercury in the tank?
Answer in units of kg.
Answer:
Mass = 2734.875 kg
Explanation:
Given that A water holding tank measures 85 m long, 55 m wide, and 9 m deep.
The volume = 85 × 55 × 9 =
= 42075 m^3
Traces of mercury have been found in the tank, with a concen- tration of 65 mg/L.
1 m^3 = 1000 L
Convert cubic meters to litres.
42075 × 1000 = 42075000 L
From definition of density,
Density = mass ÷ volume.
Substitute the given density and the calculated density into the formula
65 = mass ÷ 42075000
Cross multiply
Mass = 65 × 42075000
Mass = 2734875000 mg
Convert mg to kg
To do that, you will divide the answer by 1000000
2734875000 ÷ 1000000
= 2734.875 kg
If the pressure of a gas is increased, then the volume will decrease because the particles of the gas will be forced more closely together.
The independent variable is
.
The dependent variable is
.
Then the independent variable is the pressure of the gas while the dependent variable is the volume of the gas as it depends on the variation in the pressure of the gas.
What is an ideal gas?It is an imaginary gas for which the volume occupies by it is negligible, this gas does not exist in a practical situation and the concept of an ideal gas is only the theoretical one,
A gas's volume will decrease as its pressure rises because the gas's particles will be pressed closer together.
As the volume of the gas depends on the fluctuation in the gas's pressure, the independent variable in this situation is the gas's pressure.

While participating in a blood drive at school, Keona learns that blood has a density of 1.06 g/mL. She donates one pint of blood, which is equal to 473.176 mL. What is the mass of the blood Keona donates, to the nearest hundredth of a gram?
Answer:
m≈501.57 g
Explanation:
The density formula is:
d=m/v
Let’s rearrange the formula for m. m is being divided by v. The inverse of division is multiplication, so multiply both aides by v.
d*v= m/v*v
d*v=m
The mass can be found by multiply the density and the volume.
m=d*v
The density is 1.06 grams per milliliter and the volume is 473.176 milliliters.
d= 1.06 g/mL
v= 473.176 mL
Substitute the values into the formula.
m= 1.06 g/mL * 473.176 mL
Multiply. When multiplying, the mL will cancel out.
m= 501.56656 g
Let’s round to the nearest hundredth. The 6 in the thousandth place tells us to round the 6 to a 7 in the hundredth place.
m ≈501.57 g
The mass is about 501.57 grams.
