Answer:
(a) 12210 Ω
(b) 9.92 Ω
Explanation:
From Electricity,
(a)
When resistors are connected in series, the total resistance is the sum of the individual resistance.
From the question,
Rt = R1 + R2 + R3................................. R37 ....................... Equation 1
Where Rt = Total resistance of combined resistance, R1 = resistance of the first resistor, R2 = Resistance of the second resistor .......... and so on up to the 37th resistor.
Note: Since The resistor are identical.
Rt = n(R) ..................... Equation 2
Where n = number of resistor, R = resistance of each resistor.
Given: n = 37, R = 330 Ω
Substitute into equation 2
Rt = 37(330)
Rt = 12210 Ω
(b)
For parallel connection,
Rt = R/n...................... Equation 2
Given: R = 330 Ω, n = 37
Substitute into equation 2
Rt = 330/37
Rt = 8.92 Ω
Hence the resistance when connected in parallel = 9.92 Ω
Pretty sure it is A:Light wave
As they say nothing is faster than the speed of light.
C. Gravity acts on all objects in the universe!
Answer: The correct answer is-
C) The cost to develop the technology would be greater than what could be made in profits.
As per the information in the question, company believes that electric cars are the future of the automotive industry.
It indicates that in future, automobile industries will flourish and get maximum profit through selling of electric cars. This idea will only be fulfilled if the cost to develop the technology would be less and the profit made out of it is significantly larger.
Thus, out of the given factors, only option C) The cost to develop the technology would be greater than what could be made in profits will prohibit the company from developing the idea.
Answer:
C. while the magnet is moving
Explanation:
Electromagnetic induction implies the production of electric current by mere movement of a magnet with respect to a coil or wire.
In the given question, current would be induced in the wire only when the magnet moves. That is either when the magnet is pushed into a wire, or when pulled out. But no current would flow through the wire when the magnet is left there for a while.
The current is induced because of the motion involved. Thus, the appropriate option is C.
