If you were given distance & period of time, you would be able to calculate the speed.
Hope this helps!
Answer:
Lifting overcomes the pull of gravity. Heavier objects need to have a strong force to lift them. Try lifting a bag of cement and see if it's easy or hard.

when pee is forced through the ureters.
Answer:
a. the density will not change
b. D' = 0.125 D
So, the density will change by a factor of 0.125
Explanation:
a.
Density is the material property and the value of density is constant for all solid materials. So, when the dimensions of the a solid are increased, while the material is same, then the material must be added to the object for increasing its dimensions. So, with the increase in the volume, the mass of the object also increases. And as a result the density of the object remains constant.
Since, here the material remains the same.
<u>Therefore, the density will not change</u>
<u></u>
b.
Density = mass/Volume
D = m/V ------------ equation (1)
Now,
V = LWH ----------- equation (2)
Now, if each dimension increases by a factor of 2, the volume becomes:
V' = (2L)(2W)(2H)
V' = 8 LWH
using equation (2)
V' = 8 V
So, for constant mass, density becomes:
D' = m/V'
D' = m/8V
using equation (1)
D' = D/8
<u>D' = 0.125 D</u>
<u>So, the density will change by a factor of 0.125</u>
The approximate speed of sound is about 761 mph or 335.28 meters/second.
<h3>What's the approximate speed of sound?</h3>
If we consider the normal atmosphere at sea level, the speed of sound is about 761 mph or 335.28 meters/second. The speed of sound is different in different mediums such as solid and liquid.
So we can conclude that the approximate speed of sound is about 761 mph or 335.28 meters/second.
