That is a vector. It is a combination of direction and velocity. (You can think of Vector from Despicable Me to help you remember the term)
:)
At atmospheric pressure, a gas will have a certain density at that pressure. Density is measured a mass divided by the volume. If you increase the pressure in a cylinder of constant mass of gas particles, you decrease the volume at which gases occupy thus from the equation density is equal to mass over volume, a volume decrease with a constant mass yields a higher density. Therefore increasing the pressure increases the density.
I'm pretty sure it's frying an egg because you can't un-fry the egg
The different seasons are mainly cause by a planet's tilt of it's axis.
In short, Your Answer would be Option C
Hope this helps!
Answer:
V=15.3 m/s
Explanation:
To solve this problem, we have to use the energy conservation theorem:
the elastic potencial energy is given by:
The work is defined as:
this work is negative because is opposite to the movement.
The gravitational potencial energy at 2.5 m aboves is given by:
the gravitational potential energy at the ground and the kinetic energy at the begining are 0.
