From what height did a body weighing 9.8 kg fall if it hit the surface at a speed of 100 km/h? - Bronze figurine alloy
The bronze figurine weighs 0.5 kg. Bronze is an alloy of tin and copper in a ratio of 1:4. How many grams of copper and how many grams of tin does the statuette contain? - 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? - Aluminum cylinder
The aluminum cylinder weighs 1400 g and is 26 cm high. Its density is 2700 kg/m³. Calculate the base area of the cylinder and express the result in cm². - Above water surface
If we remove the stone from the water, we apply a force of 120N. How much force will we exert if we move the stone above the water? The stone's density is 5000 kg/m³. - Locomotive pressure
What is the pressure on the tracks when a 10-ton locomotive with eight wheels stands on it, and each wheel has a contact area of 4 cm²? - Duo mix
One kilogram of meat of two colors is 650 g of pork, and the rest is chicken. One kilogram of pork is 40 CZK, which is more expensive than a kilogram of chicken. How many CZK (Czech crowns) cost one kilogram of chicken meat so that the price of one kilogr - Electrostatic
A proton with mass mp = 1.67.10-27 kg and electric charge e = 1.6.10-19 C, whose initial velocity was zero, is acted upon by a homogeneous electrostatic field of unknown intensity E. The proton moves in the direction of the lines of force and on a path s - Roller fluid
The homogeneous roller weighs 7.36 kg and has a volume of 8 dm³. Use the MFCH tables to select the fluids in which the specified body declining blue, it floats. - Wool ball
Mrs. Black used 1.2 kg of wool to knit the sweater. The shop sold a wool ball weighing 100 grams for 39 CZK. How much money would she save if she knitted the sweater herself than if she bought it for CZK 720 in the shop? (CZK is Czech currency = Kč) - Bread loaf
