Answer:
The total volume of the air is 1000 cubic centimeters.
Explanation:
Since the bicycle pump and the bicycle tyre have the same pressure, then the total volume of the air is the sum of the volume of each element, then we translate this into the following artihmetical expression:


The total volume of the air is 1000 cubic centimeters.
Explanation:
do we can say that the first step is finding the acceleration of the object. We do so by saying F = ma
so a = F/m
a = 500 m/s^2
we now have the time, acceleration and initial velocity.
so we can find the final velocity by using one of newtons equations which is: vf = vi + at
so:
vf = 0 + 500 × 12
vf = 6000
note that our initial velocity was zero since the object was initially at rest.
if you still have any doubt dont hesitate to ask for further help.
Answer:
Definitive
Explanation:
Definitive estimate should be done very early in a project or even before a project is officially started and is used for making many purchasing decisions for which accurate estimates are required and for estimating final project costs. Therefore, if the cost estimate for a project is a basis for contract awards and performance reporting, it should be definitive estimate and as accurate as possible.
Answer:
mm
Explanation:
As we know that

where
m represents the order of minimum
y represents the distance on the screen of the minimum from central axis
λ is the wavelength of the light
D is the distance between screen-to-slit
d represents the width of the slit
For first minima

For second minima


Answer:
In physics, a polar vector is a vector such as the radius vector that reverses sign when the coordinate axes are reversed
Explanation:
Polar vectors are the type of vector usually simply known as "vectors." In contrast, pseudovectors (also called axial vectors) do not reverse sign when the coordinate axes are reversed.
