The y-axis of the speed-time graph is the speed while the x-axis is the time of travel. In this case, the slope is equal to the change in y over change in x. Change in y is velocity difference while change in x is time difference. Since v<span>elocity difference/ t</span><span>ime difference is the slope, the answer is acceleration. </span>
Answer: The correct order of energy transformation is from CHEMICAL ENERGY to ELECTRICAL ENERGY to LIGHT ENERGY
Explanation:
Energy which is simply defined as the ability to perform work is made up of different forms, these include:
- Mechanical energy: Associated with machines at work.
- LIGHT ENERGY: produced by light bulbs
- ELECTRICAL ENERGY: taking in by television set and other electrical appliances.
- CHEMICAL ENERGY: stores in food and other fuels
- Sound energy: Produced by vibrating objects example piano, drums.
According to the law of conservation of energy, energy can neither be created nor destroyed in a closed system, but can be transformed from one form to another, thereby keeping the energy in the closed system constant. From the question, the circuit is an example of a closed system and the order of energy transformation taking place is from the battery (CHEMICAL ENERGY) to ELECTRICAL ENERGY(power source) to LIGHT ENERGY(bulb). I hope this helps, thanks.
Answer:
Attached below
Explanation:
The plot showing the potential as a function of distance from the center of the sphere is attached below
note : The Potential inside the sphere will remain constant as potential remains constant on surface and it start to decrease as 1/r
Bro again the same type of sum..
well
it takes 3 second to hit the ground
the height will be
h = 5*3*3
h = 45m
horizontal distance would be
velocity*time
10*3 ,= 30m/s
Let the total weight of the body be = x
Let the weight of the heart of the mammals be = y
Now the given percentage of 0.5 %, we will convert it into decimal form,
so this is equal to 0.005 in decimal form,
so the linear equation that gives the heart weight in terms of body weight will be,
y = 0.005x
