Is momentum in m per s?
No. m per s is speed. Multiply it by a mass, such as kg, and you have momentum.
How will you divide 8kg rice into 2 equal halves only with the help of a 5kg and a 3kg pot?
you want to end upwith 2 pots each with 4 kg Here is one way: 1. Fill the 3kg pot from the 8 kg bag; yhe 3kg pot has 3 kg in it and the bag is left with 5 kg 2. Pour the 3 kg pot into the 5kg pot and it now has zero, the 5kg pot has 3 kg 3.Pour the 5kg from the bag into the 3 kg pot. Thereis now 2 kg in the bag , 3 kg in the 3 kg pot, and still 3kg in the 5 kg pot. 4. Pour the 3 kg from the 3 kg pot into the 5 kg pot until full. Now there is 1 kg in the 3 kg pot, 5 kg in the 5 kg pot, still 2 kg in the bag of rice 5. Pour the 5 kg fromthe 5 kg pot into the bag and then the 1 kg from the 3 kg pot into the 5 kg pot. Now the bag has 7 kg, the 5 kg pot has 1 kg and the 3 kg pot has zero 6. Fillthe 3 kg pot from the 7 kg bag; the bag has 4 kg now, the 5 kg pot has 1 kg and the 3 kg pot has 3 kg 7. Pour the 3 kg from the 3 kg pot into the 5 kg pot; the 5 kg pot now has 4 kg in it and the bag also has 4 kg in it That's it - there has to be an easier way?
What is Emc square?
Correctly written it is E = mc^2 'E' is energy 'm' is mass 'c' is ther speed of light in a vacuum. It is the Einsteinian theory relating energy to mass. What it means is in a nuclear reactor , the mass of the nuclear fuel is converted into energy by the loss of mass. The mass placed in the reactor may be say 1 kg. It undergoes nuclear disintegration, forming two or more new elements of less mass ( say 0.999 kg) that the originsal mass . The loss being energy. !!!!! Notice it is a very tiny loss , but produces a huge amoint of energy.
How much force is needed to accelerate a 3 kg skateboard at 5m per s squared?
Force = mass * acceleration Force = (3 kg)(5 m/s2) = 15 Newtons ===============( takes about 1 Newton to press a doorbell )
