What allows a person to walk the Earth: a) atmosphere b) Earth response c) feet d) rolling friction - 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 - Grass seed calculation
We should sow grass in a square-shaped garden with a side of 16.2 m. How many kg of grass seed do we need? One square meter is necessary for 25 grams. - The gold coin
The gold coin contains 900 permille of pure gold. The coin weighs 950g. How much permille is gold? How many grams are gold? - A flower pot
The concrete flower pot has the shape of a cube with an edge of 45 cm, and the thickness of the walls and bottom is 4 cm. A) Calculate the clay volume in the flowerpot if it reaches 3cm below the rim. B) Calculate the weight of the flowerpot if the concre - Ferko weight calculation
The ball weighs 0.55 kg. Ferko weighs 100 times more. How many kg does Ferko weigh? - The farm
The farm harvested 390 tons of grain. Wheat was 15% more than barley, and rye was 126 tons less than wheat and barley combined. How many tons of wheat, how many tons of barley, and how much rye did the team get? - Washing powder
A 10-kilogram pack of washing powder is M euros more expensive than a 5-kilogram pack of the same powder. A 5-kilogram package costs P euros. Five kilos of packaging is not worth it because it is more expensive than half the price of 10 kilos. How much is - Fruit salad
The fruit salad is prepared from oranges and bananas. One kilogram of oranges costs 30 CZK, and one kilogram of bananas costs 18 CZK. How many kilograms of bananas need to be added to half a kilogram of oranges to produce a fruit salad worth CZK 21 per 1 - Spruce log weight
Spruce logs with a diameter of 270 mm and a length of 4 m are carefully loaded onto a wagon with a bed width of 2,700 mm and stacked in 9 layers. How much does such a load of spruce wood weigh if its density is 700 kg/m³? - Shopping payment calculation
