Is it possible for a distance versus-time graph to be a vertical line?

Answers

Answer 1

Answer: If time is the x axis and distance is the y axis then yes, in the case that time is going by but distance remains the same.

Answer 2

Answer:

Answer:

In a distance-time graph, time is on the horizontal axis, or x-axis, and distance is on the vertical axis, or y-axis. As an object moves, the distance it travels increases with time. ... You can use the steepness, or slope, of a line in a distance-time graph to determine the speed of an object if speed is constant.

Which type of graph is best used to show the amount of product formed under different reaction conditions?a. box and whisker plot
b. circle graph
c. bar graph
d. scatter plot

this was on my physics test, but idk why... is this even science? but help, please ;-;

Answers

Answer:

The correct answer is c. bar graph.

Explanation:

The best visual tool to show the amount of product formed under different reaction conditions is the bar graph. This tool is also called the bar diagram or the bar chart. The bar graph uses bars to make comparisons among different categories. It can be presented horizontally or vertically. This tool shows that the longer the bar, the greater its value. Bar graphs mainly consist of two axes.

most likely, I think a scatter plot would be best

Explanation:

A graduated cylinder is filled to an initial volume of 12.7 ml. A rock Is dropped into the graduated cylinder. The final volume of the graduated cylinder is 18.2ml. What is the Rocks volume in both ml and cm3? What method was used to determine this?

Answers

Answer:

V = 5.5 mL

Explanation:

The volume filled in the graduated cylinder is 12.7 mL

now when a stone is dropped into the cylinder then the volume of liquid is raised to final level of 18.2 mL

so as per the theory of given by Archimidies we can say that the volume of the object is exactly same as the volume displaced by the object

So here the volume displaced by the object is given as

$V_(displaced) = V_f - V_i$

$V_(displaced) = 18.2 mL - 12.7 mL$

$V_(displaced) = 5.5 mL$

so the volume of the object is given as

$V = V_(displaced)$

$V = 5.5 mL$

First of all, ml and cm^3 are equal. The volume of the rock is 5.5 ml. This is found by subtracting the volume of just the water from the combined volume of the rock and the water leaving you with just the volume of the rock. This is method is using water displacement.

25. You are asked to find the area of a room that is 4.56 m long and 5.668 m wide. How many significantfigures should you show in your answer?
A. 5
B. 3
C. 7
D. 4

Answers

Answer:

Option B

Explanation:

The two dimensions have the following significant numbers

4.56- 3 significant numbers

5.668- 4 significant figures

When responding, we give area as per the most precise number given hence the smallest (most precise) significant figures in these two numbers is 3. Therefore, the area will be given to 3 significant figures ie

4.56*5.668=25.84608 square meters

Area=25.8 square meters

What effect would the temperature have on the time kept by a pendulum clock if the pendulum rod increase in length with an increase in temperature

Answers

As we know the time period of pendulum is given by the equation

$T = 2\pi \sqrt{(L)/(g)}$

so here

L = length of the pendulum

Now on increasing the temperature due to thermal expansion the length of the pendulum will increase and due to this the time period of the pendulum will also increase

Now due to increase in time period of the pendulum the clock will become slow and it will give incorrect time due to this increase in temperature

Thermal expansion increases the pendulum period, and the clock will lose time

Further explanation

Simple Harmonic Motion is the motion of an object (repetitive movement) through its equilibrium point where the frequency of vibrations / oscillation per second is constant

The motion that occurs in the pendulum is one example of simple harmonic motion

Terms used:

Deviation (y): the object's distance from the balance point
Amplitude (A): maximum deviation
frequency (f): number of vibrations at any time
Period (T): the amount of time in one vibration

Whereas the relationship T and f:

$\displaystyle T=(1)/(f)\n\nf=(n)/(t)$

n = number of vibrations / oscillation

t = time (s)

Formula used:

$\large{\boxed{\bold{T=2\pi \sqrt{(L)/(g) }}}\rightarrow (1)/(f)=2\pi \sqrt{(L)/(g) }$

From this formula shows that the period is proportional to the length of the pendulum rod.The longer the pendulum rod , the greater the amount of time in one vibration

If thermal expansion occurs in the pendulum clocks, the pendulum rod changes in length ,proportional to the temperature change, and increases the pendulum period, so the clock will lose time
