The answer is C! I knew this way before taking the test
Answer:
5ms^-2
Explanation:
F = 20N, m = 4.0kg, a = ?
Using the formula for Force
F = ma
Then making acceleration the subject of the formula
a = F/m
a = 20N/4.0kg
a = 5ms^-2
Answer:
Those substances which can conduct electricity are called conductors, while those substances which don't conduct electricity are called insulators.
Resistance is the obstruction provided by the material through which the current passes,so since conductors conduct electricity and insulators don't,so the obstruction i.e resistance provided by the conductor must be less,while insulators being unable to conduct electricity,has very high resistance.
Example of conductor is copper
Example of insulator is plastic
