What is the correct definition of speed?
A. time (hours or seconds)
B. time per distance (hours per mile or seconds per meter)
C. distance per time (miles per hour or meters per second)
Answer:
C
Explanation:
The correct definition is distance / time, although teachers like to mix you up sometimes. A question like "How many minutes per mile does it take to go 3miles in 20 minutes?" In this question, the units are upside down.
The standard answer is what is the rate of speed when when 3 miles are covered in 2 hours.
Here the answer is 3/2 = 1.5 miles / hour which is the standard way of writing speed or rate. distance / time.

If you touch the two probes together while the DMM is set to resistance, what will happen?
The meter will read 0 ohms
The meter will short circuit and trip a protective circuit
The meter will read infinite ohms (as high as its scale goes)
The meter will show the equivalent voltage of the meter's internal battery
If the meter's battery is good and the meter is working OK, it should read zero ohms.
Most meters have a little adjustment wheel on the side to SET the reading to exactly zero when the probes are touched together.

What is a primary source?
A.A textbook that explains a wide range of science topics
B.A technical article written by an experimenter
C.A newspaper article about a recent discovery
D.A summary of research written for an average reader
Answer:
Explanation:
B
A primary source is one that is written by the person who lived through an advenure or is one doing the action and recording it.
In this case, the answer is B.
Most frequently, for a historian, a primary source is something like a diary or a bunch of letter written by someone experiencing something.
It cannot be about someone else's work. Not C or D
A textbook is not the answer either. It is a bulky summary of scientific, or other kind of thought.

How does the field of science gain knowledge and understanding?
A basic question about how science gains knowledge.
Science gains knowledge using the scientific method.
The first thing you need to understand here is the scientific method, with all the steps and a little explanation to each one.
Ask a question or find some problem to solve: (what you want to understand? In what area do you want to find new knowledge?) Perform research: (There is some existing knowledge in that topic?) Establish your hypothesis: (This is what you can conclude with the things you know, or what you expect to find) Test your hypothesis by conducting an experiment: (Perform an experiment to test your hypothesis, this is the most important part.) Make an observation: (Observe the outcome of the experiment) Analyze the results and draw a conclusion: (study what the outcome means) Present the findings: (Present what you learned to the scientific community, in this way the science gains knowledge).If you want to learn more, you can read:

Blaise is driving a car that is traveling 6.03 m/s and accelerates uniformly at 2.5 m/s² to reach a speed of 12.9 m/s. How long does it take for this acceleration to occur?
It would take 0.3639 seconds for this acceleration to occur.
Given the following data:
Initial speed, U = 6.03 m/sFinal speed, V = 12.9 m/sAcceleration, a = [tex]2.5 \;m/s^2[/tex]To find how long it takes for this acceleration to occur, we would use the first equation of motion.
Mathematically, the first equation of motion is given by the formula;
[tex]V = U + at[/tex]
Substituting the values into the equation, we have;
[tex]12.9 = 6.03 + 2.5t\\\\2.5t = 12.9 - 6.03\\\\2.5t = 6.87\\\\t = \frac{2.5}{6.87}[/tex]
Time, t = 0.3639 seconds
Therefore, it would take 0.3639 seconds for this acceleration to occur.

1. A car weighs 1000kg, you can push it .05 m/s2, how much force (F) are you applying
to the car? Here we use F=MA:
F= 1000 x .05
F= 50 newtons
Mass of the car (m) = 1000 Kg
Acceleration (a) = 0.05 m/s^2
Let the force we are applying to the car be F N.
By using the equation,
F = ma, we get
F = 1000×0.05 N = 50 N
Answer: We are applying 50 N force to the car in the direction of motion.
A dog runs 20 m east and then 35 m west in 12 seconds.
What is the dog speed? What is the dogs velocity?
Answer: Dog's speed = (20 + 35) /12 = 4.583 m/s
Dog's velocity = (20-35)/12 = -1.25 m/s
Explanation: Speed is a scalar quantity so we don't care about direction which means we add the magnitude of both the directions i.e. east and west.
About the velocity, it's a vector quantity. So, we must be very careful with the directions and signs. In cartesian coordinates system, we generally take the right side of origin as the positive x-axis and the left side of origin as the negative x-axis. So, considering the same fact, we consider east as positive side and west as the negative side.
Therefore, when we add 20m + (-35m), we get = -15m and you already have the time period of 12 s.
Precision is how close a series of measurements are to ______
Answer:
Accuracy is how close a measured value is to an accepted value. Precision is how close measurements are to one another. To make measurements, you have to evaluate both the accuracy and the precision to get a correct value.
what is the relationship between the variables on this graph? The temperature does not have an effect on flow time. As the temperature increases, the flow time increases. As the temperature increases, the flow time decreases.
Answer: As the temperature increases, the flow time increases.
Explanation: i took the test
The relationship between the variables on this graph is that As the temperature increases, the flow time increases, therefore the correct answer is option B.
What is the kelvin scale of temperature?It is a scale of temperature used to measure the temperature, the kelvin scale of temperature is also known as the absolute scale of temperature.
The Standard International unit of thermodynamic temperature is the kelvin, often known less frequently as the degree Kelvin. The formal definition of one kelvin is 1/273.16 of the thermodynamic temperature of pure water's triple point.
As shown in the graph as the temperature increase across the X axis the flow time is increasing as well, these two variables are directly proportional to each other.
Thus, The graph shows a link between the variables, showing that when the temperature rises, flow time also rises, hence option B is the proper response.

Q23 In Hindu chronology, the longest time measure is a para. One para equals 311 040 000 000 000 years. Calculate this value in megayears, hours and in seconds. Write your answers in scientific notation.
The conversion in megayears, hours and seconds are :
[tex]1 \: para \: = \: 3.11 \times {10}^{8} \: megayears[/tex]
[tex]1 \: para \: = \: 2.72 \times {10}^{18} \: hours[/tex]
[tex]1 \: para \: = \: 9.81 \times {10}^{21} \: seconds[/tex]
Given that :
1 para = 311040000000000 years
1 mega year = 1 million years :
311040000000000 years expressed in mega years will be :
Let : number of mega years = p
1 mega year = 1,000,000 years
p = 311040000000000 years
Cross multiply :
311040000000000 × 1 = 1,000,000 × p
311040000000000 = 1000000p
p = 311040000000000 / 1000000
p = 311040000 mega years
p = 3.1104 × 10^8 mega years
[tex]1 \: para \: = \: 3.11 \times {10}^{8} \: megayears[/tex]
In hours :
In hours : 8760 hour = 1 year
Let : number of hours = p
1 year = 8760 hours
311040000000000 years = p
Cross multiply :
p = 8760 × 311040000000000
p = 2724710400000000000
p = 2.72 × 10^18 hours
[tex]1 \: para \: = \: 2.72 \times {10}^{18} \: hours[/tex]
In seconds :
31536000 seconds = 1 year
Let : number of hours = p
1 year = 31536000 seconds
311040000000000 years = p
Cross multiply :
p = 31536000 × 311040000000000
p = 9808957440000000000000
p = 9.81 × 10^21 hours

A projectile is launched vertically with an initial velocity of 50 m/s. How long would it take to reach the top of the launch?
Answer:
Explanation:
Givens
vi = 50 m/s
vf = 0
a = - 9.81
t = ?
Formula
t = (vf - vi)/a
Solution
t = (0 - 50)/-9.81
t = 5.097
Notice that a is made into a minus. It does not mean subtract. It means that the direction of the projectile and gravity must go in opposite directions. You will find that direction is a critically important consideration in physics.
Answer:
It'd take it 5.10 seconds
Explanation:
At the top of the launch, it is maximum height, h
formular derivation :
At maximum height, final velocity, v is zero
From first newtons equation:
[tex]{ \sf{v = u + gt}}[/tex]
v is the final velocity
u is the initial velocity
g is acceleration due to gravity
t is the time taken
but v is zero:
[tex]0 = u + gt \\ gt = u \\ t = \frac{u}{g} [/tex]
since it is vertical motion, u = usin(theta), where angle is 90°
[tex]{ \boxed{t = \frac{u \sin( \theta) }{g} }}[/tex]
t is the time taken to reach the top of the launch:
substitute, taking g to be 9.8 m/s²
[tex]t = \frac{50 \times \sin(90 \degree) }{9.8} = \frac{50}{9.8} \\ \\ { \boxed{ \boxed{time = 5.10 \: seconds}}}[/tex]
