- Electric charge
An electric current of 100 mA flowed through the conductor for 160 s. What electric charge passed through it? - Legs and ratio
The legs of a right triangle are in the ratio a:b = 6:8. The hypotenuse has a length of 61 cm. Calculate the perimeter and area of this triangle. - Rhombus IV
Calculate the length of the diagonals of the rhombus, whose sizes are in the ratio of 1:2 and a rhombus side is 35 cm. - Ball collision speed
Two inelastic/plastic balls move towards each other with equal velocities of 2 m/s. The weight of one ball is 3 kg, the other 1 kg. Determine the speed of the balls after the collision and the loss of kinetic energy. - A turtle 2
A turtle can walk 1/12 of a kilometre in an hour. The turtle is 1/5 of a kilometre away from a pond. How long will it take the turtle to reach the pond at this speed? - Brick lifting work
How many bricks do they have to lift on a 1.2 m high flatbed if I want to do the work 5.88kj and one brick weighs 5 kg? - Rock lifting calculation
Can a boy lift a 75 kg rock from the bottom of a pond if we assume he will raise a 50 kg rock in the dry? The density of stone is 2500 kg/m3, and the density of water is 1000 kg/m3 - Five pumps
Three same pumps fill the tank with 50400 liters of diesel in 7 hours. How many liters of diesel will it take in 4 hours if we add two more of the same pumps and pump them the same way? How much more (or less) will they get if we add 2 of the same pumps a - Velocipedes
In the 19th century, bicycles had no chain drive, and the wheel axis connected the pedals directly. This wheel diameter gradually increased until the so-called high bikes (velocipedes) had a front-wheel diameter of up to 1.5 meters, while the rear wheel w - Aquarium - water level
The aquarium measures 40 cm, 40 cm, and 50 cm. The water reaches 45 mm from the upper edge. Norbert bought the fish, and when he put them in the aquarium, the step level was 0.5 mm. What is the volume of new fish? - The vase
The vase is a cylinder with a diameter of 1.2 dm. From the upper edge to the water level, it is 20 cm, and the water depth is 35 cm. If it were filled to the brim, how much ml of water would fit in it? - Measuring aquarium
The aquarium has the shape of a block measuring 80 cm, 30 cm, and 20 cm. The water level reaches 6 cm below the upper edge. How many liters of water are in the aquarium? (1 liter = 1 dm3) - Water in well
The water in the well is dropped by one ring; the ring has an inner diameter of 110 cm and a height of 80 cm. How much water is left in the well? The chutes are concrete rings forming the walls of the well. - Running track
To the Akčesú races there came 25 runners. The running track was however narrow, and therefore always only five runners could run at once. What surprised Sára and Arthur the most however was the fact that the Te-TiVá people do not have stopwatches, nor ot - The angles
The angles in the triangle are in the ratio 12:15:9. Find the angles. - Ring gold volume
The ring weighs 28 g and has a volume of 2 cm³ to find out if it is made of pure gold. - The temperature 29
The temperature at 6 P.M. is -11°Fahrenheit. During the night, the temperature rises by 7 °F drops by 3 °F, and rise by 5 °F. What is the temperature after these changes? - Toy car length
On the Christmas flyer, we find a toy car model reduced in a ratio of 1:43. What is the car's actual length in the picture in decimetres if the manufacturer states a length of 14 cm? - Temperature difference
Libya's highest temperature was recorded at 58 degrees Celsius, and the lowest was recorded at -88 degrees Celsius. What is the temperature difference? - Cork water interaction
