To develop this problem it is necessary to apply the concepts of sum of capacitors in a circuit, either in parallel or in series.
When capacitors are connected in series, they consecutively add their capacitance.
However, when they are connected in parallel, the sum that is made is that of the inverse of the capacitance, that is where, C is the capacitance.
For the given case, it is best to connect two of these capacitors in series and one in parallel, so
We have three 100 pF capacitors, then
Here we can see how two capacitors 1 and 2 are in series and the third in parallel.
Investing equality
Adding it in parallel, then
True.
Conductivity is the ability to transmit heat, electricity or sound. Conductivity is a physical property.
A physical property is one which can be measured or observed without changing the composition or identity of a the substance.
Conductivity is a physical property because the composition of the substance does not change.
A copper wire is still a copper wire when it is conducting electricity. Like wise, an aluminum rod is still an aluminum rod when heated. It is conducting heat but the heat does not change it, it is still an aluminum rod during the whole process.
Answer:
98 N
Explanation:
Given that The weight of an object is the product of its mass, m, and the acceleration of gravity, g (where g=9.8 m/s2). Of an object’s mass is m=10. kg,
The parameters to be considered are
Mass m = 10 kg
Acceleration due to gravity = 9.8m/s^2
Weight W = mg
substitute mass m and acceleration due to gravity g into the formula above.
Weight = 10 × 9.8
Weight = 98 N
Therefore, the weight of the body or object is 98 N
