Answer:
(a) 1.414 km
(b) 1.06 m/s
Explanation:
(a) For John:
Distance = 1 km north and then 1 km east
Speed = 1.5 m/s
total distance traveled = 1 + 1 = 2 km = 2000 m
Time taken to travel = Distance / speed
t = 2000 / 1.5 = 1333.3 seconds
Displacement =
(b) For jane :
Time is same as john = 1333.33 second
Distance = 1.414 km = 1414 m
Speed = distance / time = 1414 / 1333.33 = 1.06 m/s
The answer is periosteum. Hope this helps!
Assuming that this gas is in ideal state, we can use the relation that for every 1 mol of an ideal gas it would have a volume of 22.4 L. But before using this, relation we need to convert the number of grams of H2 into moles by using the molar mass of 2.02 g/mol.
moles H2 = 0.00922 g ( 1 mol / 2.02 g ) = 0.005 mol H2
Volume H2 at STP = 0.005 mol H2 ( 22.4 L / 1 mol ) = 0.102 L of H2
The the Water turns to ice. But even then they would never truly stop moving.<span />
Answer:
The work done is 85200 J or N•m
Explanation:
Here,
Force = 200 N
Distance = 426 m
Now, For work done
<h3><u>Formula</u><u>:</u></h3>
<u>Work = Force × Distance.</u>
W = F × d
W = 200 × 426
W = 85200 J or N•m
Thus, The work done is 85200 J or N•m
