Question

Ко дну сосуда прикрепили кусок льда.После того,как в сосуд налили воду(её масса равна массе льда ),лёд полностью оказался под водой.На сколько процентов понизится уровень воды в сосуде после того ,как весь лёд растает ?

Answer 1

Vo1=V1+V2=m/po1+m/po2=m(1/po1+1/po2)

Vo2=2m/po1

po1- плотность воды (=1)   ро2 - плотность льда (=0,9)

Vo2/Vo2=2*po1*po2/(po1+po2)=0.95

Уровень понизится на 5 %

Answer 2

Calculation of the Change in Water Level

To calculate the change in water level after all the ice melts, we need to consider the mass of the ice and the mass of the water. According to the given information, the mass of the water is equal to the mass of the ice.

Let's assume the initial water level in the vessel is h1, and the final water level after all the ice melts is h2. We need to find the percentage decrease in the water level, which can be calculated using the formula:

Percentage decrease = ((h1 - h2) / h1) * 100

To proceed with the calculation, we need more specific information about the dimensions and shape of the vessel. Unfortunately, the search results provided by You.com do not contain the necessary information to calculate the change in water level accurately. Therefore, we are unable to provide a precise answer to your question at this time.

If you can provide additional details about the vessel's dimensions or any other relevant information, we would be happy to assist you further in calculating the change in water level.
