Answer:
u will need good car parts and a very well made engine
Explanation:
u need a good engine because if u only work on the outer layer of the car the inner parts will be slow and old and the car will have problems
Answer:
An opamp is an operation amplifier. It takes an input signal and amplifies it on the output side.
An ideal opamp should have infinite impedance at its input, infinite gain on the output, and zero impedance on the output
Answer:
Young's modulus for this alloy of nickel is 1.997×10^11 N/m^2
Explanation:
Young's modulus = stress/strain
Stress = Force (F)/Area (A)
F = mg = 59 kg × 9.8 m/s^2 = 578.2 N
A = πd^2/4 = 3.142 × (0.19/100)^2/4 = 2.836×10^-6 m^2
Stress = 578.2/2.836×10^-6 = 2.039×10^8 N/m^2
Strain = extension/length = 2.86×10^-3 m/2.8 m = 1.021×10^-3
Young's modulus = 2.039×10^8/1.021×10^-3 = 1.997×10^11 N/m^2
Answer:
1. Auto is the best mode since it is the cheapest
2. Safety, reliability, convenience should be considered
Explanation:
1.
This person is willing to pay $25 per hour.
To get the mode, which is the best choice I used this formula
Cost of trip + 25T
T = time or number of hours
By air travel
Cost = $600, T = 8 hours
600+25(8)
= 600+200
= 800 dollars
By rail,
Cost = $450
T = 16 hours
450+25(16)
= 450+400
= 850 dollars
By auto,
Cost = $200
T = 20 hours
200+25(20)
= 200+500
= 700 dollars
From these calculations the cost of Traveling by auto is the cheapest so it is the best mode.
2. Other factors to consider when choosing an alternative mode of transport
A. Safety: this transportation material should be able to get to it's destination without any form of damages happening
B. Reliability: the material should be able to fulfill it's requirements
C. Convenience: in terms of availability per day and also the frequency of traveling time
Answer:
E=23,976 J
Explanation:
Given that
I = 1.8 Ah
Voltage = 3.7 V
We know that 1 h = 3600 s
I = 1.8 x 3600 A.s
I=6480 A.s
The energy in Jules given as
E= V. I
We know that unit of V.I is Watts ( J/s) and when multiple by seconds then we get Joules.
E=3.7 x 6480 Watt.s
E=23,976 J
Therefore the energy in joule will be 23,976 J.
