Answer:
It looks like its moving north.
Explanation:
Thermal energy is the answer
Initially they are connected in parallel, so they have the same voltage V=120 V at their ends. Therefore we can use Ohm's law to calculate the resistance of each appliance:


When they are connected in series, they are crossed by the same current I. The equivalent resistance of the circuit in this case is

, so we can use Ohm's law for the entire circuit to find the current in the circuit:
Answer:
0.4 N
Explanation:
Draw a free body diagram of the block. There are three forces: weight force mg pulling down, buoyancy force ρVg pushing up, and tension force T pulling up.
Sum of forces in the y direction:
∑F = ma
T + ρVg − mg = 0
T = mg − ρVg
T = g (m − ρV)
Plugging in values:
T = (9.8 m/s) ((2.5 g/cm³ × 20 cm³) − (1 g/cm³) (10 cm³)) (1 kg / 1000 g)
T = 0.392 N
Rounded to one significant figure, the reading of the spring scale is 0.4 N.
Answer:
When you rub a balloon on a sweater or your hair, the <u>electrons</u> are transferred to the balloon giving it a <u>negative</u> charge. The balloon will then <u>repel</u> any object that has a different charge.
hope this helps :)
