Is buoyancy related to the depth of water
No, it's only related to the volume of boiled water
Does the buoyancy of an object depend on its depth
It has nothing to do with the volume of liquid and the density of liquid
Is buoyancy related to depth?
Suppose there is a cube sinking in water, f floating = ρ GH2 * s - ρ GH1 * s (immersed in water) = ρ GS * Δ H = ρ liquid GV discharge (general) = g discharge. When the object is suspended or floating, f floating = g matter = m matter G
So it doesn't matter
Xiaoming's home is 23 kilometers away from the supermarket. Xiaoming goes at the speed of 30 meters per minute and has a 10 minute break. How many rolls of toilet paper did Xiaoming buy in the supermarket?
It's estimated to be quite a lot. I have to rest for ten minutes
Xiao Li goes out at 8 o'clock and walks to her classmate's home 12 kilometers away. Her walking speed is 3 kilometers per hour, but she has to rest for 10 minutes every 50 minutes______ We will arrive at the end of the day
It takes 4 hours and 40 minutes for her to go out at 8 o'clock and arrive at her classmate's home at 12:40
Xiao Ming goes to grandma's house 10 kilometers away by bike. The speed is 40 km / h. can he get there in 3 hours
Theoretically, it can, because 3 * 40 = 120 > 10
Xiaomei from home to school, first walk 8 minutes 1 hour to the station, waiting for 10 minutes in the bus station, and then take a car 4 minutes 1 hour to school
How many hours did it take
1 / 8 + 10 / 60 + 1 / 4 = 1 / 8 + 1 / 6 + 1 / 4 = 3 / 24 + 4 / 24 + 6 / 24 = 13 / 24 hours
Xiao Ming goes to school through Xiao Liang's home, and the distance between them is 1 km. Xiao Ming takes 10 minutes less to go to school by bike than Xiao Liang does on foot
Xiao Ming's cycling speed is 9 km / h, and Xiao Liang's walking speed is 4 km / h. how long does it take them to go to school
If Xiaoliang's home is x km away from the school, then Xiaoming's home is x + 1 km away from the school
Countable equation (x + 1) / 9 = x / 4-10 / 60
The solution is x = 2km
So it takes 2 △ 4 = 0.5 hours for small light
Xiaoming needs 3 △ 9 = 1 / 3 hour
It usually takes a few minutes to walk 300 meters
According to scientific research, normal adults can walk about one meter per second, 300 meters takes about five minutes. I hope I can help you
Compare one fifth of eight meters with one eighth of five meters
One fifth of an 8 meter is 8 / 5 meters
One eighth of five meters is 5 / 8 meters
Obviously 8 / 5 > 5 / 8
So one fifth of eight meters is greater than one eighth of five meters
