- Cycling distance
We cycled 8 km, a third of the distance we traveled. How many kilometers do we have to travel? - Rocket speed development
The rocket develops a higher speed, which is: a) higher velocity of escaping gases b) higher mass of escaping gases c) greater momentum of escaping gases d) shorter rocket length - Density - Au
What volume is 1/2 kg of gold? The density of gold is 19.3 kg/dm³. - Pool water filling
They filled the 25 m long, 15 m wide swimming pool with water to a height of 80 cm. How many hectoliters of water did they put in, and how long did it take for the pool to fill if 375 hectoliters flow in 1 hour? - Mike chose
Mike selected four identical cubes, three identical prisms, and two identical cylinders from a construction kit. Each cube has an edge length of 3 cm. Each prism has two dimensions the same as the cube, and its third dimension is twice as long. Each cylin - Sand loading
The truck, with a load capacity of 7 tons, has a storage area of 4.5 m and 2.1 m. The weight of 1 m³ of wet sand is 2,000 kg. How high can we load the sand, so the car's load capacity is not exceeded? - Roof repair
To repair the roof, we need 15 pieces of boards 6 m long, 15 cm wide, and 25 mm thick. If 1 m³ of boards costs 500 euros, how many euros will we pay for all the boards? - Copper sheet weight
The copper sheet metal has a thickness of 3 mm, is 0.9 meters long, and is 75 hundred meters wide. How many kilos does it weigh if one dm³ copper weighs 8.8 kg? - Perpendicular parking
Which parking lot for 5 cars occupies a larger area, perpendicular or inclined at an angle of 45°, and how much? The car has dimensions of 4 m and 2 m. - Percentages
Calculate the percentages to two decimal places: a / 15 min in 4 hours B / 35 cm² of 12.5 dm² c / 2 dm² of 400 cm² D / 0.2 liters from 2.2 liters - Force gauge 2
A force gauge measured a gold necklace as Fg = 0.48 N in air and Fw = 0.45 N in water. Is it made of pure gold? - A chemist
A chemist recorded the change in temperature of a cooling liquid as −25.5° over a 1.5-minute period. The temperature fell at a constant rate. What was the rate of change in temperature? Enter your answer in the box. °F per minute - Weather
Weather. At 5:00 am, the temperature was 28 °C, and at noontime, it rose by 9 °C. By 4:00 PM, it dropped 3 °C; by nighttime, it was 4 °C less. What is the room temperature this time? - Race car loss
Two race cars passed the finish line at a speed of 216 km/h at a distance of 0.003 s. Express the loss of the second in centimeters. - Car speed compliance
Police found that the car had traveled 300 m in 20 seconds. He complied with the driver's maximum allowed speed of 50 km/h - Current in the bulb
The bulb is rated 6 V, 0.2 A. Determine the current rating of the bulb. - Aluminum resistance temperature
The aluminum line has a resistance of 7.6 Ω at -10˚C. What will be its resistance at a temperature of + 50˚C? - Gold carat calculation
I have a pile of 48 grams of 12-carat gold. How many grams of gold do I have in a pile? - Ice floe
What is the volume of an ice floe weighing 326 kg? - Wavelength
