Atsmopheric pressure is the pressure that is on something inside and atmosphere. measured in either mmhg or milimeters of Mercury, or atmospheres abreviated atm.
2 gram piece of iron, because is doesn't float.
Answer:
LHS=RHS=[L]
Explanation:
Given mathematical expression:

where: dimension:
s = displacement length ![[L]](https://tex.z-dn.net/?f=%5BL%5D)
u = initial velocity ![[L.T^{-1}]](https://tex.z-dn.net/?f=%5BL.T%5E%7B-1%7D%5D)
t = time ![[T]](https://tex.z-dn.net/?f=%5BT%5D)
a = acceleration ![[L.T^{-2}]](https://tex.z-dn.net/?f=%5BL.T%5E%7B-2%7D%5D)
now using dimensional analysis:
![[L]=[L.T^{-1}]\times [T]+[L.T^{-2}] [T]^2](https://tex.z-dn.net/?f=%5BL%5D%3D%5BL.T%5E%7B-1%7D%5D%5Ctimes%20%5BT%5D%2B%5BL.T%5E%7B-2%7D%5D%20%5BT%5D%5E2)
we know that the ratio and constants have no dimension.
![[L]=[L]+[L]](https://tex.z-dn.net/?f=%5BL%5D%3D%5BL%5D%2B%5BL%5D)
as we know that only similar dimensions can be added or subtracted therefore we get a correct conclusion.
<em>However we can deduce the operators between the equations and can neither check for the validity of the constants. We can only check for the dimension of the terms involved.</em>
Answer:
500 J.
Explanation:
Work done = force * distance
= 25 * 20
= 500 Joules.
Answer:
Explanation:stop it cause the sun don't shine that long unless if it's summer cause the summer time is very hot it may be 100 degrees or lower
