Answer:
F = ma or Force = mass x acceleration.
Explanation:
Newtons second law is about the force put onto an object. To find this you would use the formula:
Force is equal to mass times acceleration (F=ma)
Ethene on combustion reaction produces CO₂ and H₂O,
C₂H₄ + 3 O₂ → 2 CO₂ + 2 H₂O
According to Equation,
28.05 g (1mole) C₂H₄ produced = 88 g (2 mole) of CO₂
So,
100 g of C₂H₄ will produce = X g of CO₂
Solving for X,
X = (100 g × 88 g) ÷ 28.05 g
X = 313. 72 g of CO₂
Answer:
Your question is missing some information.
But in most of the systems, potential energy and kinetic energy are inversely proportional
Answer:
NH2- has two pairs of bonding and two pairs of non-bonding electrons participated in the formation of a molecule. The central nitrogen atom has two pairs of non-bonding electrons cause repulsion on both bonding pairs which pushes the bonds closer to each other. So, NH2- has a bent (angular) molecular geometry.
Explanation:
This question is about momentum conservation, which belong to physics subject.
You start by assuming that the friction coefficient of bwtween the roller skates and the ice is very low and think there is not friction.
Under those circumstances the convservation of momentum implies:
1) When the roller skater throws the 2 kg balls, it will acquire a momentum equal to v*2kg and the skater will acquire equal momentum in the opposite direction.
That means that the skater will step back and away from the other skater.
2) When the second skater receives the ball with momentum 2kg*v, he will move backward also and further away.
In conclusion, the two skaters will end standing more than 5 m apart facing each other.
