is an untrue statement - because the object could not float - it could be anywhere in the fluid
Answer:
<h2><u>✍</u><u> </u><u>What is quantum physics?</u></h2>
- ➳ It's the physics that explains how everything works; the best description we have of the nature of the particles that make up matter and the forces with which they interact.
- Quantum physics underlies how atoms work, and so why chemistry and biology work as they do.
The answer is true to your question
Answer:
There are many examples of electrostatic phenomena, from those as simple as the attraction of the plastic wrap to one's hand after it is removed from a package to the apparently spontaneous explosion of grain silos, the damage of electronic components during manufacturing, and photocopier & laser printer operation
Answer:
Np=130 turns, Is=220 A
Explanation:
Part A:
Ns=100 turns
Vp= 1.5*104 V = 156 V
Vs= 120 V
As Np/Ns= Vp/Vs
⇒ Np=
⇒Np=
Np= 130 turns (It has two significant figures)
Part B
Is=280 A, Vs=120 V, Vp= 1.5*104 V= 156 V
For ideal transformer
Pin=Pout
Ip*Vp= Is*Vs
⇒Ip=()
⇒Ip=
⇒Ip=215.4 A
to represent it as two significant figures we will write as
⇒Ip=220 A
