Answer:
Assuming it starts at 72 kmph and hits a dead stop: Divide 72 by 60 for distance per minute. So, 1.2km per minute. 1.2km is 1200m and 4 seconds is one fifteenth of a minute.
Explanation:
Answer:
mass of 1 mole of person is 6.02 times more than the mass of earth
Explanation:
Number of atoms in 1 mole = Avagadro Number
now we know that average mass of one person = 60 kg
so total mass of 1 mole of persons
now the comparison of this mass of 1 mole of person with the mass of earth is as following
So mass of 1 mole of person is 6.02 times more than the mass of earth
Answer:
no
Explanation
non-metal and metal are two different things
The equivalent resistance of the three resistors when connected in parallel is:
Since the three resistors in this problem are identical, we can call R their resistance, and we can rewrite the previous equation as
And since we know the value of the equivalent resistance,
, we can find the value of R:
Now the problem asks us what is the equivalent resistance of the three resistors when they are connected in series. In this case, the equivalent resistance is just the sum of the three resistances, so
