A machine has mechanical advantage 2,what does it mean?
Answers
Answer:
The mechanical advantage of a machine is 2. Mechanical advantage MA is the ratio of output (generated by the machine) force to input (applied to the machine) force. So MA = 2 means that for example if you apply 100 N then your machine will multiply that force and generate 200 N .
While spending the weekend in your cabin, you burn wood in your pot-bellied stove to heat a kettle of water for tea.
Answer the following questions for 2 points each:
1. What type of energy does the wood have in this situation. Explain your answer.
2. What type of energy is this transformed into as the wood it burned in the stove. Explain your answer.
3. What type of heat transfer is being used to warm the kettle of water? Why does the water eventually boil?
Answers
Answer: 1 = Heat
2=gas
3=it gets hot enough to boil because the metal conducts the heat into the water to heat it up and eventually boil.

Students in a science class were provided with this image and asked to identify which color of light would refract the most if white light was passed through a prism?which student below identified the correct color of light with the proper justification?
Answers
The identification of the correct color of the light with the proper justification would be by student 4: violet, because it has the highest frequency, therefore the correct answer is option D.
What is Wavelength?It can be understood in terms of the distance between any two similar successive points across any wave for example wavelength can be calculated by measuring the distance between any two successive crests.
As given in the problem, students in a science class were provided with this image and asked to identify which color of light would refract the most if white light was passed through a prism.
Student 4 would correctly identify and justify violet as the appropriate hue of the light since it has the greatest frequency, making option D the right response.

An object travels in a straight line for 1200 m at a velocity of 50 m/s, what is its time of travel?
Answers
Given that,
distance = d = 1200m
velocity/speed = s = 50m/s
time = t
Also,
s = d/t
And,
t = d/s
t = 1200/50
t = 120/5
t = 24
Therefore, it takes 24s to travel.
Answer: Therefore, the travel time of a car that travels 1200 meters at 50 m/s is 24 seconds.
Explanation:
An object travels in a straight line for 1200 m at a velocity of 50 m/s, what is its time of travel?
Data:
d = 1200 m
V = 50 m/s
t = ?
The formula for uniform motion is:
V = d/tWhere
V = speedd = distancet = timeWe clear the formula for time t:
t = d/v
t = (1200 m)/(50 m/s)
t = 24 s
Therefore, the travel time of a car that travels 1200 meters at 50 m/s is 24 seconds.

A subway car moves at a constant speed of 10 m/s over a period of 10 s. What is the instantaneous speed halfway through this motion
Answers
Answer: 10 m/s
We're told the speed is constant, so it's not changing throughout the time period given to us. So throughout the entire interval, the speed is 10 m/s.
A force of 30 Newtons is used to push a basket along the floor a total distance of 3 meters. How much work is done on the basket?
Answers
Answer:
the total work done is 90J
Explanation:
the reason why is because you are the force (30 newtons) and the metere (3) so you will be multiplying those two numbers together.
W= FD 30(3)= 90J
What, exactly, is moving across the medium?
Answers
Answer:
So waves are everywhere. But what makes a wave a wave? What characteristics, properties, or behaviors are shared by the phenomena that we typically characterize as being a wave? How can waves be described in a manner that allows us to understand their basic nature and qualities?
A wave can be described as a disturbance that travels through a medium from one location to another location. Consider a slinky wave as an example of a wave. When the slinky is stretched from end to end and is held at rest, it assumes a natural position known as the equilibrium or rest position. The coils of the slinky naturally assume this position, spaced equally far apart. To introduce a wave into the slinky, the first particle is displaced or moved from its equilibrium or rest position. The particle might be moved upwards or downwards, forwards or backwards; but once moved, it is returned to its original equilibrium or rest position. The act of moving the first coil of the slinky in a given direction and then returning it to its equilibrium position creates a disturbance in the slinky. We can then observe this disturbance moving through the slinky from one end to the other. If the first coil of the slinky is given a single back-and-forth vibration, then we call the observed motion of the disturbance through the slinky a slinky pulse. A pulse is a single disturbance moving through a medium from one location to another location. However, if the first coil of the slinky is continuously and periodically vibrated in a back-and-forth manner, we would observe a repeating disturbance moving within the slinky that endures over some prolonged period of time. The repeating and periodic disturbance that moves through a medium from one location to another is referred to as a wave.

How much time is required for a 20 Coulombs charge to flow through a point if the current is 2 amperes? help plzzzzz
Answers
The time required for a 20 coulombs charge to flow through a point if the current is 2 amperes will be 10 seconds.
What is electric current?Electric current is defined as the ratio of the charge flow in a given time interval. It is denoted by I. It has the unit is ampere.
The given data in the problem is;
t is the time is required
q is the charge = 20 Coulombs
I is the current is= 2 amperes
The formulas for the elctric current are given as;
[tex]\rm I = \frac{q}{t} \\\\\ \rm t = \frac{q}{I} \\\\ \rm t = \frac{20}{2} \\\\ t=10 \ sec[/tex]
Hence the time required for a 20 coulombs charge to flow through a point if the current is 2 amperes will be 10 seconds.
