МатематикаВопрос:
Peresnyaloprotyukova El'dar decided to check the air pressure in his bicycle tires. The figure shows the readings of the manometer used by El'dar for measurements. Normal tire pressure corresponding to El'dar's weight is 2.8 atmospheres. How much does the measured tire pressure differ from what it should be? 1 bar (bar) = 1 atm.
Ответ:
Дано:
- Нормальное давление: 2,8 атм
- Показание манометра: 5 бар
- 1 бар = 1 атм
Решение:
- Переведём показание манометра в атмосферы: 5 бар * 1 атм/бар = 5 атм.
- Найдем разницу между нормальным и измеренным давлением: 5 атм - 2,8 атм = 2,2 атм.
Ответ: 2,2

- A heater with a power of P = 60 W is placed in water with ice floating in it. The specific heat of fusion of ice is λ = 330 kJ/kg. 1. How much heat will be released by the heater in time t = 500 s? 2. What mass of ice will melt in this time? Assume that the temperature of water and ice remains constant throughout the experiment and that all the ice melts during the experiment. 3. Due to voltage surges in the network, the heater's power can vary by ±5%, and the experimental time is measured with an absolute error of Δt = 5 s. In what range can the mass of ice melted during the heater's operation lie? Assume other quantities are known precisely.
- The figure shows a graph of the temperature of a substance over time. Determine after what time after the start of heating the substance completely transitioned into a liquid state, assuming it was initially in a solid state.
- When assembling the electrical circuit shown in the figure, the student noticed that as the rheostat slider moved from right to left, the ammeter readings decreased: at the extreme right position of the slider, the ammeter showed 9 A, and at the extreme left, 1 A. Assuming that the resistance of the light bulb does not change during this experiment, determine the ratio of the light bulb's resistance to the maximum resistance of the rheostat.
