Answer:1.33 hr
Explanation:
Given
Speed of airplane relative to air=627 km/h
Distance traveled =787 km
Speed of wind=38.4 km/h
Wind is blowing in opposite direction therefore net speed is
thus time taken is
It forces the mercury to rise, being pushed up the tube by pressing down on the dish.
I hope I could help :)
Answer:
This statement is true, a heating curve is a graph that shows the temperature change of a substance as thermal energy is introduced.
The object's speed will remain constant after the it leaves his hand.
So will HIS speed in the opposite direction.
Answer:
Diameter of Wire = 4.5 mm
Explanation:
First, we need to find the fractional part of the reading. The fractional part o the reading can be given by the following formula:
Fractional Part = Circular Scale Reading x Least Count
where,
Circular Scale Reading = 50
Least Count = 0.01 mm
Therefore,
Fractional Part = (50)(0.01 mm)
Fractional Part = 0.5 mm
Now, the diameter of the wire can be given by using the following formula:
Diameter of Wire = Linear Scale Reading + Fractional Part
Diameter of Wire = 4 mm + 0.5 mm
<u>Diameter of Wire = 4.5 mm</u>
