The maximum take-off weight of the Concorde aircraft is 185,000 kg. What reserve does it have for fuel, passengers, and their luggage if the plane's weight is 78,900 kg? - In the apple
In an apple orchard, 12 part-time workers were picking apples for 5 days. Their daily performance in kilograms was as follows: 155.6; 168.2; 175; 159.4; 169.5. When calculating, round the results to hundredths. a) On average, how many kg of apples did the - Steel weight thread
A round steel weight (ρ1=7800 kg/m3) is suspended on a thread and immersed in water (ρ2=1000 kg/m3). The volume of the weight is 1 dm³. With what force is the thread stretched? - Ton hour comparison
A) how many kg is 4/5 tons more than 7/10 tons? b) by how many minutes is 1/3 of an hour less than 5/6 of an hour? - Stone kinetic energy
What is the kinetic energy of a stone weighing 1 kg that falls in free fall 5 seconds from the start of its motion? g= 10 m/s squared. - Water tube pressure
Water flows in a horizontal tube at a speed of 2.24 m/s and has a pressure of 0.1 MPa. How fast does the water flow in the narrowed part of the tube if its pressure is 0.09 MPa? - Car braking force
What constant braking force is required to stop a car weighing 1 ton in 10 seconds traveling at 50 km/h? - Robinson on the island
Robinson Crusoe came to the island with 4 grains of corn. How many years did it take him to grow enough grain for bread if he got 10 grains from one grain on average and he needed at least 1 kg of bole for 1 bread, and 1 grain weighs about 0.2 g? (assume - Seed mixture tons Farmers on Mr. Dvořák's farm sowed 3.5 tons of feed mixture seeds after the harvested wheat. This seed was blended from oats and vetiver. We know that 1t of this seed was worth 2840 CZK, 1t of oats 3000 CZK, and 1t of vetiver 2800 CZK. From how many tons
