- Road - permille
A 5 km long road begins at an altitude 500 meters above sea level and ends at an altitude of 521 ASL. How many permille road rises? - two spacecraft
Recently, two spacecraft successfully landed on two small planets labeled α and β. Both ships were equipped with sensitive sensors that measured the basic parameters of the asteroids. The sensors found that the day α took six times longer on planet α than - Liquid mass volume
The liquid has a specific gravity of γ = 9050 N. m-3. Calculate its specific gravity, the mass of 2 m³ of this liquid, and also of 3 m³ of this liquid. - Tunnel passage time
The Branisko tunnel has a length of 4975m. How long will a car pass through the tunnel if the speed limit is 80km/h? - Children room plan
An architect has two plans for the same apartment at different scales. On the first plan, at a scale of 1:20, the length of the children's room is 20 cm. What is the children's room size on the second plan, on a scale of 1:50? - Bulb resistance
Determine the resistance of a bulb whose wattage at a source voltage of 220 V is 15 W. - Car speed
The car covered the track 157.5 km in 2 hours and 15 minutes. How fast was he moving? - Aluminum resistance temperature
The aluminum line has a resistance of 7.6Ω at -10˚C. What will be its resistance at a temperature of + 50˚C? - Plane dusting distance
The plane dusted the field in 25 minutes at 252 km/h. How many kilometers has it flown? - Electric motor power
A current of 2 A at a voltage of 400 V passes through the electric motor. The electric motor is switched on for 0.5 h. What is the power input of the electric motor? - Water drainage
1000 l of water will drain in one outflow in 4 hours. How many hours will it take for 9000 l 3 drains to drain? - Jet distance
What distance (in km) will the jet fly at 500 km/h in 12 minutes? - Four-fifths of the pool
The rectangular pool, with bottom dimensions of 12 m and 25m, is 200 cm deep. The first faucet flows 2.4 hl per minute and the second 6 l per 1 second. How long will it take for the pool to be filled to four-fifths of its height? - Glass sheet weight
What is the weight of a sheet of glass 75 cm x 120 cm and 2 mm thick if one cubic meter of glass weighs 2500 kilograms? - Electric charge
The electric current in a microprocessor circuit is 0.230 μA. How many coulombs pass a given point in the circuit in 1.50 ms? - The temperature 17
The temperature was -5 Celsius at 6 AM. It increased by a speed of three degrees every hour for six hours. The temperature then increased 1 1/2° every hour for five hours. What was the temperature at 5 PM? - Compressed gas
The pressure vessel contains a compressed gas at a temperature t1 = 27°C and a pressure p1 = 4 MPa. How much does its pressure change when we release half the amount of gas, and its temperature drops to t2 = 15°C? - The appliance
The appliance has a power input of 2.3 kW. It is connected to the mains voltage of 230 V. What is the current flowing through the appliance? - Rollerblade
