Instantaneous acceleration is defined as rate of change in velocity
it is given by the equation
so here it shows that acceleration is always depends on change in velocity with time and now if we required this change in velocity with time for a small instant of time then it will be given by the slope of velocity and time graph.
So here the graph must be like this to find the slope of any graph we always use the concept that for any graph between y and x we use
if we compare it with the formula of acceleration above
then on Y axis we must have to draw the speed and on x axis we must have to draw the time
so correct answer must be
<u> d) Place time on the x-axis and velocity on the y-axis</u>
Answer:
The most abundant gas in Earth’s atmosphere is nitrogen, followed by oxygen, which is needed to burn wood and fuel. The third-most abundant gas is argon. The amount of carbon dioxide in the atmosphere is very small, making up just 0.33% of the atmosphere, but it is very important because plants use it to make simple sugars. Another important gas is water vapor, which condenses around small particles in the atmosphere to form clouds and then rain.
Explanation:
To develop this problem we will apply the energy conservation theorem and the principle of work. Basically we will have that the kinetic, potential and work energy must be equivalent to the kinetic energy just before the impact. We will start converting the units given to the British system and then proceed with the Calculations.
Remember that according to the energy balance in this case it would be balanced like this
Here
m = mass
= Velocity at each moment
= Work by drag
h = Height
g = Acceleration due to gravity
Mass
Initial Velocity
Work by drag
By work energy principle
Replacing,
Solving for , we have that
Converting this value,
Therefore the velocity of the aircraft at the time of impact is 962.85mi/h
Answer:
It depends on the potential energy it has ontop of the ramp. The marble has the same potential energy was the kinetic energy without changing the ramp incline or moving it. What kinetic energy shows is what potential energy made it to be, so we look at how the ramp is placed. If the ramp is a steep incline the kinetic energy will be fast. It depends on the weight of the marble too. If the marble is heavy the potential energy will slowly tansition to kinetic energy while a light marble will transition to kinetic energy fast. But marbles are light so there we have it. It basically goes from potential energy to kinetic energy to thermal energy to potential energy. Make me brainliest pls :)

Answer:
if there isn't a shorting mechanism, the whole sets will be blown out several lamps and then shortened, the overall resistance of the remaining operating lamps will be decreased resulting in an increased working current that is adequate to blast the fuse
