Answer:
Straight Line
Explanation:
For an ideal gas,
PV = nRT
For a fixed quantity ( constant number of moles) of a gas at fixed temperature
Right side of the equation will be constant
Thus,
PV = C
So, P = .
Thus P is directly related to
That's why plot between P and will be an straight line.
After they have gathered enough information by testing the theory.
Answer:
An object's acceleration is the rate its velocity (speed and direction) changes. Therefore, an object can accelerate even if its speed is constant - if its direction changes.
Explanation:
D
Using the kinetic energy 1/2mv^2 formula
5*10^5 is the answer
Answer:
head straight across the river (perpendicular to the bank).
Explanation:
To cross the river in the shortest time first your velocity should be relative to the earth has to have the largest possible component to the bank
suppose,
<em>S</em><em> be the swimmer </em>
<em>E </em><em>be the earth</em>
<em>W </em><em>be the water</em>
<em /><em> be the velocity of X relative to Y</em>
resultant velocity relative to E will be:
is parallel to the bank so,
has its largest component perpendicular to the bank when is in that direction
so to cross the river in the shortest time you should straight across the current will then carry you downstream so your path relative to the earth is directed at angle downstream
