Answer:
Its density decreases, and its volume increases
Explanation:
Density is defined as Mass/Volume. What happens when water transforms into ice is that its density decreases because the volume the molecules now occupy increases.
The denominator of the rational expression is now larger (while the numerator stays the same), so the quotient gives a smaller number.
Answer:
Acceleration of the plane, a = 5.4 g
Explanation:
It is given that,
Speed of the jet plane, v = 1890 km/h = 525 m/s
Radius of the arc, r = 5.20 km = 5200 m
The plane is moving in the circular path, the centripetal acceleration will act on it. It is given by :
We know that, the value of g is,
So, the acceleration of the plane is 5.4 g. Hence, this is the required solution.
