Put a stick in the ground and look at the changes in the direction and length of its shadow.
You could put a stake vertically in the ground and make a mark on the ground where the shadow of the top of the stake is throughout the day and year.
The Sun doesn't: "move across the sky" Earth revolves around the Sun which is why it appears to "move across the sky".
The moon appears to travel across the sky due to the Earth's rotation on its axis. As the Earth rotates, the moon's position in the sky changes, giving the illusion that it is moving. This movement is consistent with the cycle of day and night.
The sun appears to move from east to west due to the rotation of the Earth. In reality, the sun itself does not move across the sky, but the Earth's rotation causes it to appear as though the sun is moving across the sky.
The sun appears to move across the sky due to the Earth's rotation, completing a full circle in about 24 hours.

I believe the word you're looking for is "diameter".
Because the earth is rotating.
A current flows through, not across, a circuit. And, yes, you can measure it using an ammeter.
The " Ohm " is. 1 ohm is the resistance across which 1 volt of EMF appears when the current through it is 1 Ampere.
They are meters to measure
Voltage flow into a starter motor, never out of it. Use the voltmeter to measure the voltage at the starter motor before starting to crank and then whilst it is cranking. (Before cranking, the voltage appears across the starter motor relay only.)

Generally with a tape measure going across the center line.
The type of friction you observe when you slide books across a table top is kinetic friction. This type of friction occurs between two surfaces that are in motion relative to each other.
To measure the voltage across a component in an electrical circuit, a voltmeter can be connected in series by placing the voltmeter in the same path as the component. This allows the voltmeter to measure the voltage drop across the component accurately.
you measure across the top of the cylinder if it is a cylinder or across the circle if it is flat
