Explanation:
The given statement"If the pressure of a gas sample is quadrupled and the absolute temperature is doubled" is false.
Answer: Option B
<u>Explanation:</u>
As we know the direct relationship between Pressure and Temperature by the Gay-Lussac’s Law,

From this, we get,


So, according to given statement, we have 
Then from the above expression, we can find out the value of
when pressure increased by 4 times of initial pressure as,

Hence, we get,

Hence, from the above expression we can say that as we increase the pressure four times, the temperature does not get doubled. So, the given statement in the question is false.
Answer:
The answer is b.) and d.)
Explanation:
The options to reduce the background noise in magneto-medicine are given as follows:
a.) Orienting the heart parallel to the Earth's field
- This will have no significant effect on the measurements.
b.) Taking the difference of two nearby sensor measurements (gradiometer).
-This answer is TRUE.
c.) Placing the heart in a perpendicular fashion to the Earth's magnetic field.
_ This answer also will not have any significant effect on measurements.
d.) Using physical means to shield environmental fields.
- This answer is TRUE.
Light travels in waves, and light travels at about 3.0x10^8 m/s. and you call that this the 'speed of light' so your answer possible could be
A. It travels at the speed of light.
I might be wrong so double check.
