Answer:
Independent.
Explanation: The <em>Independent</em> variable is sometimes called the "manipulative" because it refers to a quantity that is changed by the experimenter.
“RESISTANCE” is a property that determines how much current will flow for a given source voltage, whereas a “RESISTOR” is a device that controls the current in a circuit.
Answer:
The work done by the child to reach the cat is, W = 3684.8 J
Explanation:
Given data,
The mass of the child, m = 40 kg
The height of the cat from the ground, h = 9.4 m
The force acting on the child due to gravitational force is,
F = mg
The minimum force required by the child to climb the tree against the gravitational force is,
F = mg
Hence, the work done by the child is,
W = F · h
= 40 x 9.8 x 9.4
= 3684.8 joules
Hence, the work done by the child to reach the cat is, W = 3684.8 J
