as you pump more gas into the balloon, the particles become more packed, in an attempt to gain more room, the particles push on the walls of the balloon, therefore, making it expand.
I think it is "A'' 'It moves along straight lines in air and changes direction when it enters water.
Answer:
c-) both objects will reach the bottom at the same instant.
(b) decrease.
Explanation:
Although the feather is lighter than the coin, the tube where the experiment is performed is evacuated. Therefore there is no air that prevents the feather from falling freely with the same acceleration and speed as the coin.
In fact in the equations of kinematics proposed by Newton, the mass of the bodies is not taken into account, as we can see in the following equation:
where:
Vf = final velocity [m/s]
Vi = initial velocity [m/s]
g = gravity acceleration [m/s^2]
t = time [s]
Therefore the answer is C.
Gravitational pull is a function of height, as the height of the body increases, the force of gravity decreases.
Every atom with 15 protons in its nucleus
is an atom of Phosphorus.
Answer:
The distance is
Explanation:
From the question we are told that
The smallest shift is
Generally a grid unit is of an arcsec
This implies that 0.2 grid unit is
The maximum distance at which a star can be located and still have a measurable parallax is mathematically represented as
substituting values
Note
So
