<u>Answer:</u>
The velocity of the bus be is 0 miles/second
<u>Explanation:</u>
Given, a bus travelled a distance of 20 miles north and 20 miles back to the starting point
Hence, total distance = 20 + 20 = 40 miles
Velocity is calculated by the formula:
Velocity = 
Displacement = 
Velocity = 
Therefore, the velocity of the bus is 0 miles/second
Answer:
mass is the measure of the amount of weight pulled by gravity in an object B-)
Yes, it would be the last one as the zeros that appear after a non zero number are significant.
Answer:
3040 mmHg
Explanation:
Here
we have to convert 4.00 atm to mmHg
As we know that
The number of atm in 1 mmHg is 0.0013157895567935
Now there is 4.00 atm So, in mmHg it would be
And, according to this, the working is given below:
= 4 ÷ 0.0013157895567935
= 3,039.99
= 3040 mmHg
Hence, the last option is correct
And, the same is relevant and considered too
