Answer:
0.47922 kgm/s and will move right to left
Explanation:
= Mass of broccoli-tomato-pickle-onion-mushroom pizza = 235 g
= Mass of veggieburger-on-a-bun = 351 g
= Velocity of broccoli-tomato-pickle-onion-mushroom pizza = 1.65 m/s
= Velocty of veggieburger-on-a-bun = -2.47 m/s
Left to right is considered positive direction and the opposite is negative direction
Net momentum is
The combined dish has a momentum of 0.47922 kgm/s and will move right to left
Answer
i'm not 100% sure but 1764
Explanation:
Work done = gravitational potential energy
Gravitational potential energy = mass(kg) × height(m) × gravitational field strength(N/kg)
We can assume that the student is on earth so the gravitational field strength is 9.8N/kg
So work done = 60 × 3×9.8
=1764
(if you need help calculating power but if you do just divide your answer by 12 and you will get 147)
Answer:
In these reactions the products are higher in energy than the reactants. ... This barrier is due to the fact that to make CO2 and H2O we have to break 4 carbon-hydrogen bonds and some ...

Explanation:
Answer: 4.98 m/s
Explanation:
You solve these kinetic energy, potential energy problems by using the fact P.E.+ K.E. = a constant as long as friction is ignored.
PEi = 0 in this case
KEi = ½mVi² = PEf+KEf = mghf + ½mVf²
½1210*8.31² = 1210*9.8*2.26 + ½1210*Vf²
½1210*Vf² = ½1210*8.31² - 1210*9.8*2.26
Vf² = 8.31² - 2*9.8*2.26 = 4.98² so Vf = 4.98m/s
