Answer:

Attenuation = 0.458\ db

Explanation:

Given

Power at point A = 100W

Power at point B = 90W

Required

Determine the attenuation in decibels

Attenuation is calculated using the following formula

Attenuation = 10Log_{10}\frac{P_s}{P_d}

Where P_s = Power\ Input and P_d  = Power\ output

P_s = 100W

P_d = 90W

Substitute these values in the given formula

Attenuation = 10Log_{10}\frac{P_s}{P_d}

Attenuation = 10Log_{10}\frac{100}{90}

Attenuation = 10 * 0.04575749056

Attenuation = 0.4575749056

Attenuation = 0.458\ db <em>(Approximated)</em>

iVinArrow [24]

Answer:

Priming.

Explanation:

The brain is the centre of control for all animals. It coordinates the body system, breathing, beating of the heart, memory, gait, speech, sight etc.

Memory is stored in the brain ( the function of the cerebral cortex in the cerebrum). Two types of memory are the long term and the short term memory. The long term memory stores information permanently in the brain, while the short term holds the information for a while and either transfers it to the long term memory or the memory decays.

To retrieve a specific memory from the wide memory of the brain, it activates a strand that leads to the memory, this process is called priming.

Always refill your gas tank well before____.
mash [69]

Aloha~. My name is Zalgo and I am here to be of assistance with your problem. The answer to your question is D. The minimum amount of gas you can leave in your vehicle is 1/4 Full or 3/4 Empty. The most amount you will need is quite close to when your gas tank is full (so 1/4 Empty or 3/4 Full).

Hope this helps.
