Answer: Option D.
Newton's cradle has the most potential energy when the balls are at rest.
Explanation:
Newton's cradle demonstrate principle of conservation of momentum which states that when two objects collide, the total momentum before it's collision is the same as it's momentum after it collision.
Newton's cradle has the most potential energy when the balls are at rest because an object at rest or by virtue of it's position has potential energy when it's not moving or stationary. A stationary or objects at rest posses potential energy.
Potential energy is the energy posses by a body or object that is not moving or at rest or energy stored by an object by virtue of it's position.
Answer:
the moles of oxygen react only 1.05 moles
Explanation:
because the formula of methane is CH4 so it has 10 molecule so 10.5 ÷10 =1.05
The given statement is true.
Paint and coating production procedures can generate hazardous air pollutants, incorporating heavy metals. The cleaning and mixing operations can discharge certain kinds of toxic air pollutants and VOC, that is, volatile organic compounds.
Till the time, the most harmful environmental influence from paints is the discharge of VOCs at the time of drying process, that is, after the coating is applied.
Take in- photosynthesis
Return- respiration
Plants takes in carbon during photosynthesis while animals return carbon into the atmosphere during respiration.
