The volume at STP is 22.4 dm^3, you dont need to ccalculate
By definition we have to:
A system or frame of reference are those conventions used by an observer (usually standing at a point on the ground) to be able to measure the position and other physical magnitudes such as speed and acceleration of one or several objects.
The numerical value of some magnitudes can also be relative to the reference system when we refer to the relative movement. There are always mathematical relationships between the observer and the relative magnitudes.
Answer:
C. a position from which something is observed
Good for him ! If he's also adhering to a healthy diet, getting plenty of sleep, avoiding substance dependence, and minimizing his stress level, then he's doing everything he can to maximize his chances for a long, healthy, pleasant and rewarding fun life.
By definition we have that the density is given by:
Where,
M: mass of the sample
V: volume occupied by the sample
Therefore, substituting values in the given equation we have:
Answer:
the density of a sample of gas with a mass of 30 g and a volume of 7500 cm3 is:
Linear momentum is in a straight line and depends on the objects mass and velocity.
Angular (rotational) momentum depends on the objects mass, velocity, and radius.
