Answer:
There is an entity to which we have given the name dark energy which contributes to the total density but which we cannot detect by the usual methods.
It would be the bus moving at 25mph
Talking in terms of momentum, we know that momentum is conserved in a collision. Something that will cause the most 'damage' is something that posses more energy or momentum
p=mv
with velocity being the same, the object with the greater mass (the bus) will have a larger momentum and will thus cause more damage. <span />
The pitch of the sound describes its highness or lowness. ... Register refers to a particular range of pitches that an instrument can reach. For example, an instrument can be played in its lower or upper register. The lower register producing lower pitches and the upper register producing higher pitches.
I would say about less than an hour ago. Maybe even a few seconds ago.
Answer:
The speed in m/s at which water is ejected from the hole is 17.98 m/s.
Explanation:
Given that,
Height of tank
Height
Flow rate
We need to calculate the speed in m/s at which water is ejected from the hole
Using formula of speed
Where, v = speed
g = acceleration due to gravity
h = height
Put the value into the formula
Hence, The speed in m/s at which water is ejected from the hole is 17.98 m/s.
