bascially u j subtract 50 from 150 because the system lost 50 j but theres 150 in its surroundings
Answer:
B. The amounts of water and alcohol are not the same
Explanation:
Answer:
Explanation:
The expression for centrifugal force is shown below as:-
Where, m is the mass of the object = ?
v is the velocity of the object = 7.60 m/s
r is the radius
F is the force = 222 N
Diamter = 11.6 m
Radius = d/2 = 11.6 m/2 = 5.8 m
Applying the values in the above expression as:-
Answer:
Mass of the water is equal to the mass of ice
Explanation:
When ice melts, the mass remains the same even though its volume decreases leading to a decrease in density of water.
The mass remains the same because according to the law of conservation of mass, mass can neither be created nor destroyed. Since mass is neither created nor destroyed in the process of melting, the mass of water must remain the same.
