Answer:
the third statement is true
Explanation:
given data
Lenovos cost more than Dells
Lenovos cost less than Apples
solution
we have given 1st statement that is express as
cost (Lenovo) > cost (Dell) ..................1
and
2nd statement that is express as
cost (Lenovo) < cost (Apple)
so we can say it as
cost (Apple) > cost (Lenovo) ......................2
and
now above Both equation 1 and 2 can be written as
cost (Apple) > cost (Lenovo) > cost (Dell) .........................3
so we can say cost of Apples is more than the cost of Lenovos and the cost of Dells
so as that given 3rd statement is true
The answer is c. 4 seconds
Answer:
36.0 kpsi2.
Explanation:
From the question
Sut=110 kpsi
Se’=0.5(110)=55 kpsi
For surface factor ka,
a=2.70, b= -0.265, ka=a(Sut)b=2.70(110)-0.265=0.777
Assuming the worst case for size factor kb, and since 0.11 less than or equal to d less than or equal to 2in,
Therefore:
kb=0.879d-0.107 = 0.879(1.5)-0.107=0.842
Hence, the endurance strength is Se= ka kb Se’ = 36.0 kpsi2.
The response to whether the statements made by both technicians are correct is that;
D: Neither Technician A nor Technician B are correct.
<h3>Radio Antennas</h3>
In radios, antennas are the means by which signals to the sought frequency be it AM or FM are received.
Now, if the antenna is bad, it means it cannot pick any radio frequency at all and so Technician A is wrong.
Now, most commercial antennas usually come around a resistance of 60 ohms and so it is not required for a good antenna to have as much as 500 ohms resistance and so Technician B is wrong.
