The advertisement is deciribing the car’s acceleration, as it gains speed when moving from 0-60.
Answer:
By its amplitude.
Explanation:
loudness is sound intensity & intensity depends on square of amplitude. for example higher the amplitude higher the intensity which means higher the loudness.
Answer:
0.25 gram of neptunium is remaining
Explanation:
First we calculate the no. of half lives passed. For that we have formula:
n = t/T
where,
n = no. of half lives passed = ?
t = total time passed = 8 days (From Monday noon to Tuesday noon of following week)
T = Half Life Period = 2 days
Therefore,
n = 8 days/2 days
n = 4
Now, for the remaining mass of neptunium, we use the formula:
m = (mi)/(2)^n
where,
mi = initial mass of neptunium = 4.00 grams
m = remaining mass of neptunium = ?
Therefore,
m = 4 grams/2⁴
<u>m = 0.25 gram</u>
The energy that will be released will be 8.95×10^(21) Joules
for comparison, the Nagasaki atom bomb released 8.8*10^(13) Joules
so this meteorite is (8.95×10^(21))/(8.8*10^(13))=100×10^6 (100 million) times more destructive
