- A raft
I want to build a raft, and I have beams with a square section with side a=20cm and length l=2m, wood density 670 kg/m³. I will connect 10 beams - what is the volume of the raft and its weight? How deep will a raft sink in water (water density 1000kg/m³)? - The temperature 33
The temperature in Baguio City was 18.6 degrees Celsius, while in Tagaytay City was 22.5 degrees Celsius. What was the estimated difference between the two cities' temperatures? A. 6 degree celcius B. 5 degree celcius C. 4 degree celcius D. 3 degree celci - Hydrogen 60813
One liter of air weighs 1,299 g, and one liter of hydrogen 0.089 8 g. How many times is hydrogen lighter? Round the result to units. - Flatbed 47151
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?
- Sand
The maximum weight of the car is 5000 kg. We must transfer 10 m³ of sand. How many times does a car have to go? (density of sand is 1500 kg/m3) - Diameter 4126
The cork has a diameter of 20 mm and is 38 mm high. How many plugs will weigh 1 kg / cork density = 0.3 g / cm cubic /. - Average speed
What is the average speed you have to move around the world in 80 days? (Path along the equator, round to km/h). - Containers 2686
One m³ of wood weighs 650 kg, of which 12% is water. How many 10-liter containers do we need for this amount of water? - Two forces
Two forces with magnitudes of 25 and 30 pounds act on an object at 10° and 100° angles. Find the direction and magnitude of the resultant force. Round to two decimal places in all intermediate steps and your final answer.
We apologize, but in this category are not a lot of examples.
