Answer:
velocity of the object
Explanation:
For an object moving at a constant acceleration, we would expect to see a position graph with a curved shape and a velocity graph with a straight shape.

Answer:

Explanation:
The expression for the second law of motion is given below:
h = 
<u>For first half distance</u>
Object is initially at rest, so its initial speed u = 0
Object falls at half the distance, so h = h/2 where t = t1
Hence, we have

<u>For second half distance:
</u>
Similarly,
where t = t1 + t2 and u= 0
Using equation 2 by equation 1
we obtain 
Hence 
Hence 
Answer:
Hemoglobin is a protein (because it's a molecule that's not a living part of the cell but aids in cell processes).
Changing frequency of sound does not change the speed of the sound.
Explanation:
- Speed of the sound gets altered when the sound travels from one medium to another.
- Change in frequency does not affect the speed of the sound and speed is affected by the properties of the medium through which it travels.
- Therefore, to change the speed of the sound, the properties of the medium needs to be changed.
