Answer:
120 W lightbulb
Explanation:
Let the two lightbulb be A and B respectively.
Given the following data;
Power A = 120W
Power B = 90W
Voltage = 120V
To find the current flowing through each lightbulb;
a. For lightbulb A
Power = current * voltage
120 = current * 120
Current = 120/120
Current = 1 Ampere.
b. For lightbulb B
Current = power/voltage
Current = 90/120
Current = 0.75 Amperes
Therefore, the lightbulb that carries more current is A with 1 Ampere.
Direct current is the unidirectional flow of an electric charge.
The term 'unidirectional' in the statement means that direct current only moves in one direction. Direct current usually produced by things such as batteries, dynamos, and power supplies

Answer:
B-Friction
How?
Friction is when two surfaces rub against each other. This creates heat and resistance. It would only make sense that this force would slow you down will sliding across floors
