The momentum, p, is the product of the mass and the velocity:
p = m*v = 0.145 kg * 40 m/s = 5.8 kg*m/s
Answer:
while(x>=0)
{
<em>loop execution that manipulates x</em>
}
Explanation:
A while loop keep iterating as long as the condition inside is true. The necessary element to remember is to make your the condition variable is altered from within the loop. Otherwise, the loop will become an infinite loop.
The condition state that as long as the variable x is greater than or equal to 0, the loop will continue. If x becomes negative, the loop will terminate.
Energy = mass * SHC * temp change
Temp change = energy/SHC * mass
42kJ - 42000J (convert kJ to J as energy is counted as J/kg)
Temp change = 42000/4200*10
= 1C
So it goes up by 1C thus the final temperature would be 26C
Or a more logical way to think of it would be that if it takes 4200J to heat up 1kg of water by 1C (SHC is 4200J/kgC) it would take ten times the amount of energy to heat up 10kg of water by 1C hence it takes 42000J.
Answer:
0.7549kg
Explanation:
The mass of the slice + mass of the remaining cake = total mass of cake.
mass of remaining cake = total mass of cake - the mass of the slice
total mass=0.870kg
mass of slice = 0.1151kg
mass of remaining cake = 0.870 - 0.1151
mass of remaining cake=0.7549kg
