For A 53 g ice cube at −30◦C is dropped into a container of water at 0◦C, the amount of water that freezes onto the ice? is mathematically given as
x = 9.93 g
<h3>What is the amount of water that freezes onto the ice?</h3>
Where
Energy received = energy given out
Generally, the amount of water is mathematically given as
(53)(0.5)(30) = (80)(x)
Therefore
x = (49)(0.5)(16)/(80)
x = 9.93 g
In conclusion, the mass of water
x = 9.93 g

Explanation:
A object that circles around a planet is called a satellite.<span />
Answer:
The answer is 49m/s.
Explanation:
Given,
acceleration (a) =9.8m/s^2
initial velocity (u)=0 (as it was in rest condition in helicopter)
time (t) =5 s
now, final velocity (v) after 5s =?
we have,
or, v = 49m/s
Therefore, the velocity after 5s is 49m/s.

Answer: 7.8×10^5 J
Explanation:
Total energy = kinetic energy of plane + gravitational potential energy of plane.
Total energy = ((1/2)×m×v²) + (m×g×h)
Here, m is mass of plane, v is velocity of plane, g is acceleration due to gravity and h is height above the ocean.
Now,
Total energy = ((1/2)×m×v²) + (m×g×h)
Total energy = m((v²/2) + (g×h))
Total energy = 850((38²/2) + (9.81×20))
Total energy = 850(722 + 196.2)
Total energy = 7.8×10^5 J
