The formulas that will be used are:
Situation one:
The moon will be experiencing gravitational force in the form of centripetal force, so we equate the two formulas.
Gravitational force = GMm /r²
Centripetal force = mv²/r
Equating,
GMm/r² = mv²/r
v² = GM/r
The first scenario will use the formula v² = GM/r
Situation 2:
The second situation will use the simple distance over time formula for velocity, where the distance will be the circumference and the time will be in seconds.
v = 2rπ/t
Answer:
A. Wires
Explanation:
Electrical conductivity is basically how much electrical current a type of material can carry through it, so in other words it is the rate electric current can pass through it.
As you know, electrical devices rely on electricity (it's in the name) for it to function. Wires are often used in electrical equipment. Wires help connect devices to power sources. They need to be good electrical conductors in order to deliver electricity to the devices and powering it on.
Answer;
The Galápagos Islands
Explanation;
-Darwin's visit to the Galapagos Islands, helped him discover several species of finches that varied from island to island, which helped him to develop his theory of natural selection. They also helped investigate evolutionary changes in Darwin's finches.
