<h2>
Answer: C. 7.67 W </h2>
Explanation:
Firstly, we are told the three resistors are <u>connected in parallel</u>, this means we have to use the following equation to find the total resistance of the circuit:
(1)
Where: , ,
Solving (1):
(2)
(3)
(4) This is the total resistance of the circuit
On the other hand, the total power of this circuit is given by the following equation:
(5)
Where is the total voltage of the circuit.
Solving:
(6)
Finally:
(7) This is the total power of the circuit in Watts (W)
Answer:
option (c)
Explanation:
When an object thrown upwards, the value of acceleration acting on the object is acceleration due to gravity which is always acting towards the earth.
As it falls downwards, the acceleration is again equal to the acceleration due to gravity.
So, the ball's acceleration is constant.
Answer:
Electromagnetic waves differ from mechanical waves in that they do not require a medium to propagate. This means that electromagnetic waves can travel not only through air and solid materials, but also through the vacuum of space.
