Answer: Symbol A
Explanation:
The four symbols described here represent:
- Symbol A shows two dots and a line draw from one not connected to the other. --> this is an open switch. A switch is component of a circuit that is used to open/close the circuit in order to interrupt/allow the flow of current through the circuit. In this case, the switch is open, since the line does not connect the second dot.
- Symbol B shows two dots and a line draw from one connected to the other. --> this is the symbol used to represent the switch when it is closed, so it is a closed switch.
- Symbol C shows vertical lines in the pattern long, short, long, and short with a plus and minus symbol on it. --> this symbol represents a battery, which consists of two or more cells and provides the electromotive force that pushes the electrons along the circuit.
Therefore, the correct symbol representing the open switch is
Symbol A

Given:
Power of the blender is, 
Work done by the blender is, 
We know that, power is defined as the rate at which work is done by the body.
Here, we are given the power and work done and we are asked to find time taken.
Let the time of running of the blender be 't' seconds.
So, the power of the blender is given as:
Rewriting the above in terms of 't', we have
Plug in the given values and solve for 't'. This gives,
Therefore, the blender was running for 35 seconds.
