Answer:

Super

Explanation:

In object-oriented programming (OOP) language, an object class represents the superclass of every other classes when using a programming language such as Java. The superclass is more or less like a general class in an inheritance hierarchy. Thus, a subclass can inherit the variables or methods of the superclass.

Basically, all instance variables that have been used or declared in any superclass would be present in its subclass object.

Hence, when the keyword super is followed by a parenthesis, it indicates a call to the superclass constructor and it should be the first statement declared in the subclass constructor.

The energy used by an appliance which operates at 240 volts at 15 amp for 4 hr. is A. 0.92 kwhr. B. 3.45 kwhr. C. 14.4 kwhr. D.

Tju [1.3M]

Answer:

C. 14.4 kwhr.

Explanation:

To calculate the energy used by appliance first calculate the power. The formulae for calculating power(P) is $P= I \times V$ , where V stands for voltage and I stands for current.

In the given problem, V = 240 volts and I = 15 amp. Therefore,

$P=240 \times 15 =3600\ watt(w) = 3.6\ kw$

Now, formulae for calculating energy used i.e. work(W) is $W = P\times t$ , where t is the time.

In the given question time is 4 hr. Therefore energy used will be,

Energy used (W) = $3.6\times4 =14.4\ kwhr$ .
