How do you calculate the tides?

I am looking for a site where you can calculate the height and time of a sea tide anywhere in the (salt water) world for a particular date.

We have seen that normal tides are due to the gravitational force exerted by the Moon on the Earth's oceans. When the Moon, Sun, and Earth are aligned as shown in the figure below, the magnitude of the tide increases due to the gravitational force exerted...

What causes the tides? How do the spring tides and neap tides from?

I build tons of mechanical devices, but I've decided that I'd like to make them better designed. This means not just measurements of I was wondering how you calculate force? Details: 1) So I know it's measured in newtons, and the newtons are calculated...

I have made a passive solar heater out of pop cans and I need to find out how much energy (thermal) is produced. I know the equation for thermal energy is Q=m.c.dT. The problem is I can't exactly calculate the mass of air going in. I could find mass...

Is there a way to calculate how long it will take for a battery to recharge? Is there a way to calculate how long it will take for a battery to recharge, based in watt and volts, and how long the charge will last based on how many watts and volts are...

How do I calculate the between-groups variance (Vb)? I've just started a research methods class, and have a problem set due, and haven't any idea how to do it. I've got to calculate the means and variances for the two groups, as well as the between-groups...

The land moves a little at the moon's gravitational pull. The oceans move a lot, with tides lifting or beaching boats, or water lines surging high or retreating sometimes miles away from shore in places. But what of the air? Does the air get thinner...

Hi! I was just wondering how you calculate the quartiles, Q1 , Q2 and Q3 by hand? I think the questions give us like Q1 and Q3 then ask us to calculate the median (Q2) or give us the median and tell us to calculate the other two. We are only allowed...
