Always use significant figure rules. remember that these rules apply to all numbers that are measurements.
a caterpillar tries to climb straight up a wall two meters high, but for every 2 cm up it climbs, it slides down 1 cm. eventually, it reaches the top. when it reaches the top, it does not pull itself over so it will slide down 1 cm. at this point, the caterpillar was exhausted and fell to the ground. what is the total displacement?
0 up
0 down
0 n/a
199 up
199 down
199 n/a
200 up
200 down
200 n/a

Name three different units of energy used to measure heat and describe what type of situations each is usually used.

Ametal ring 4.20 cm in diameter is placed between the north and south poles of large magnets with the plane of its area perpendicular to the magnetic field. these magnets produce an initial uniform field of 1.12 t between them but are gradually pulled apart, causing this field to remain uniform but decrease steadily at 0.240 t/s . (a) what is the magnitude of the electric field induced in the ring? (b) in which direction (clockwise or counterclockwise) does the current flow as viewed by someone on the south pole of the magnet?

Which is an advantage of subdividing science into different areas?
