Answer:
Argon
Explanation:
Argon, an inert gas, is the third most abundant gas in the atmosphere.
The 7.5 is a 100 times stronger than the 5.5 . The 100 comes from the increase in scale from 5.5 to 7.5 which is an increase of two so you multiply the strength of the weaker earthquake 10^7-5=10^2=100 and that gives you the strength of the stronger earthquake!
Answer:
The answer to your question is 784.8 J. None of your answer, did you forget some information?
Explanation:
Data
mass = 20 kg
distance = 4 m
work = ?
Formula
Work = force x distance
Force = mass x gravity
Process
1.- Calculate the weight of the block
Weight = 20 x 9.81
Weight = 196.2 N
2.- Calculate the work done
Work = 196.2 x 4
Work = 784.8 J
Potential energy = mass x acceleration due to gravity x height
= 2.5 x 9.8 x 2.2
= 53.9 J.
Hope this helps!
Answer:
water leak is 650 gallons
time required to full drain is 80 hrs
Explanation:
given data
volume V = 3200 gallon
rate = V(t) = 80 - t
to find out
how much water leak between 10 and 20 hour and drain complete
solution
we know here rate is 80 - t
so here rate will be
= 80 - t
and for time 10 and 20 hour
take integrate between 10 and 20
so water leak = 
.....................1
water leak = ( 80t - 
water leak = 650
so water leak is 650 gallons
and
we know here for full tank drain condition
water leak full = 80 t - 
3200 = 80 t -
6400 = t² - 160 t
t = 80
so time required to full drain is 80 hrs
