The variable that is observed or measured during an experiment is called what type of variable?a. independent
c. controlling
b. manipulated
d. dependent

Answers

Answer 1

Answer: The correct answer for the question that is being presented above is this one: "d. dependent." The dependent variable is that one that is being measured in an experiment and which is influenced by the independent variable - the experiment measures the effect of the independent variable on the dependent variable.

Which statements about velocity are true?Check all that apply.

A. The SI units of velocity are m/s.
B. For velocity, you must have a number, a unit, and a direction.
C. To calculate velocity, divide the change in the distance by time.
D. The symbol for velocity is .

Answers

Answer

A. The SI units of velocity are m/s.

B. For velocity, you must have a number, a unit, and a direction.

Explanation

Velocity is the rate of change of displacement. Velocity unlike speed it is a vector quantity. This means that it has both direction and magnitude. The SI unit of displacement is metres while that of time is seconds. So, the SI units of velocity will be Metres per second. From the choices in the question the statements that are true about velocity are ;

A. The SI units of velocity are m/s.

B. For velocity, you must have a number, a unit, and a direction.

Answer:

A. The SI units of velocity are m/s.

B. For velocity, you must have a number, a unit, and a direction.

C. To calculate velocity, divide the change in the distance by time.

Explanation:

A - SI units for velocity are meters per second. SI (International System) of units is the metric equivalent for units, and m/s are the standard units chosen for velocity under the SI standards.

B - Velocity is a vector, meaning it has magnitude and direction. Because velocity is essentially a speed with direction, it must have units for how fast an object is moving.

C - One method of calculating velocity is distance over time: v = Δ(d/t)

D. Not sure because I'm not seeing a variable here, but the variable for velocity is generally displayed by the letter v

How has the model of our solar system changed over time?

Answers

It depends.Ptolemy was one of the most famous astronomers who was convinced that or solar system was geocentric, or revolving around the earth. Then, Copernicus came around, along with Galileo, and the attempted to convince people that that wasn't true, but that we were revolving around the sun. In fact, if you're writing an essay, a good point to add would be that Galileo spent a large part of his life imprisoned for "disobedience of the (Roman) Gods.)"

It always depends of how our solar system changed over time.

Two objects with different masses collide and bounce back after an elastic collision. Before the collision, thetwo objects were moving at velocities equal in magnitude but opposite in direction. After the collision,
A. the less massive object had gained momentum.
B. the more massive object had gained momentum.
C. both objects had the same momentum.
D. both objects lost momentum.

Answers

The more massive object will lose momentum after collision while the less massive object will gain momentum after collision.

Let the mass of the first object = m₁
Let the mass of the second object = m₂
let the initial velocities of the two objects = u
let the final velocity of the first object after collision = v₁
Let the final velocity of the second object after collision = v₂

Apply theprinciple of conservation of linear momentum for elastic collision;

let the heavier object = m₁

m₁u + m₂(-u) = m₁(-v₁) + m₂v₂

m₁u - m₂u = -m₁v₁ + m₂v₂

where;

m₁u and m₂u are initial momentum of both objects before collision

m₁v₁ and m₂v₂ are final momentum of both objects after collision

Thus, from the equation above we can conclude the following, the more massive object will lose momentum after collision while the less massive object will gain momentum after collision.
