Karl Kruszelnicki has insisted the reason why so many ships and planes vanish without trace in the area between Bermuda, Florida, Puerto Rico is nothing to do with aliens or fire-crystals from the lost city of Atlantis.
Instead, the Australian scientist ‘revealed’, the high number of disappearances is explained by nothing more supernatural than plain old human error plus bad weather and the fact that lots of planes and ships enter that area of the Atlantic Ocean in the first place.
When you shine a lite through a prism is reflects out light through all of the edges and causes light separation. Or just simply shine a laser through the edge of a sideways piece of glass.
I hope that this was helpful for you.
The efficiency of the machine is
output energy / input energy
= output power / input power
= 3,761 watts / 4,000 watts
= (3,761 / 4,000)
= 0.94025
= 94.025 %
Answer:
The circuit is in series connection,
the same current will flow through i.e
I1 = I2 = I3 = 2A.
Explanation:
We'll begin by calculating the total resistance in the circuit. This is shown below:
R1 = 4Ω
R2 = 3Ω
RT =..?
Total resistance in series can be obtained as follow:
RT = R1 + R2
RT = 4 + 3
RT = 7Ω
Next we shall determine the total current flowing in the circuit:
Voltage (V) = 14V
Resistance (R) = 7Ω
Current (I) =..?
V = IR
14 = I x 7
Divide both side by 7
I = 14/7
I = 2A.
Since the circuit is in series connection,
the same current will flow through i.e
I1 = I2 = I3 = 2A.
The weight of a barbell acting on a weightlifter in 80 N represents Fg.
<u>Explanation:</u>
Force exerted due to earth's gravity is represented as Fg. The gravitational pull is experienced by the mass of object has some force attached to by it which is called as force due to gravity.
The force is dependent upon the mass of the object experiencing the force. Hence the weight of a barbell acting on a weightlifter 80 N is the best example for Fg.
