mT = 5000 kg
v1 = 22 m/s
v2 = 20 m/s
Conservation of momentum:
Pi - Pf = 0
mT*v1 = (mT+mw)*v2
mw = (mT * v1 / v2) - mT
Mass of rain:
mw = 500 kg
water is collected in a reservoir.
Drop 10 coins of the same size and mass into a container filled with water, making sure that the water that overflows from the container is collected. Now measure the volume of the water overflow an multiply it with the density of water which is 1 kg/l. Now divide the total mass by 10 to get the mass of one coin.
Carbon dioxide (CO2) is collected by downwards delivery because it is heavier than air. Almost all of our atmosphere is nitrogen (molecular mass = 28) and oxygen (molecular mass = 32), but CO2 has a molecular mass of 40.
A common answer is more than the mass of earth.
it is collected from the ocean
rain water collected from roofs of houses,making tanks,etc.
No,it can't be collected
Rain water can be collected by directing it to a storage area.
Hydroelectric energy can be collected anywhere that water can fall. Water is usually collected from higher elevations and made to travel down long pipe sets to water turbines that convert the potential energy of the water into electricity.
the drinking water for east kilbride is collected in loch katrine near stirling
Because ammonia is quite soluble in water, so that not all of the gas produced could be collected over water.
Archimedis was so deep into thought that he filled up his bathtub full before he climbed in. When he climbed into the bathtub, the water spilled out of it and on the bathroom floor. He then realized that his mass caused the water to spill and if he collected the water and measured its mass it would be the same as his mass. He ran out of his house without wearing anything saying EUREKA!
