Taking multiple readings allows for errors (known as anomalous data points) to be spotted.For example if you were to take just one reading in an experiment and this was wrong, there would be no way of tel...
One such method is Stellar parallax. When observing stars in the night sky, stars which are further away from Earth appear to 'move' less across the sky as the earth rotates. Using this, stellar parallax ...
The displacement of the bob of mass m is given by the equation x(t)=A cos(w*t), with no phase offset as given by the boundary conditions (zero speed at t=0). By differentiating this equation twice the fir...
Mass is a measure of how much matter something has in it, measured in Kg, your current mass stays the same no matter where you are.Weight is the measure of the force of gravity acting on an object, measur...
As this is an isolated container, we know that the heat transfer with the environment is zero. Since the specific latent heat of ice is a magnitude bigger than the specific heat of water, the container wi...
