The correct answer is A <span />
Answer:
Condensation
Explanation:
Water vapour in the surrounding atmosphere lose heat and changes state from a solid to a liquid, hence forming water droplets on the outside of the bottle.
Answer:
Explanation:
= Activation energy = 160 kJ
T = Temperature = 510 K
R = Universal gas constant = 8.314 J/mol K
The fraction of energy is given by
The fraction of energy is
Ok so Net force is the vector sum of forces acting on a particle or body. The net force is a single force that replaces the effect of the original forces on the particle's motion. It gives the particle the same acceleration as all those actual forces together as described by the Newton's second law of motion.
If 2 children are both pulling on the toy and giving the same amount of Newton’s then nothing would change. If one child is giving more Newton’s then that Child would end up with the toy.
I hope this helped. I didn’t really know how to explain it. <3
Answer:
<em>The frequency changes by a factor of 0.27.</em>
<em></em>
Explanation:
The frequency of an object with mass m attached to a spring is given as
=
where is the frequency
k is the spring constant of the spring
m is the mass of the substance on the spring.
If the mass of the system is increased by 14 means the new frequency becomes
=
simplifying, we have
=
=
if we divide this final frequency by the original frequency, we'll have
==> ÷
==> x
==> 1/3.742 = <em>0.27</em>
