Answer:
the answer to the question is calcium
Answer:
<h3>1. Static electricity is a familiar electric phenomenon in which charged particles are transferred from one body to another. For example, if two objects are rubbed together, especially if the objects are insulators and the surrounding air is dry, the objects acquire equal and opposite charges…</h3>
<h3>2.1) Friction – The rubbing together of surfaces transfers electrons from one object to another. </h3><h3> 2) Conduction – Electrons flow freely through one object to another. Conductors allow charges to move easily .</h3>
Answer:
It is A
Explanation:
At year six more land became avaliable this is the only way that the population could grow so fast and it is correct on edg.
Answer:
correct answer is b
Explanation:
The frequency of a wave depends on the properties of medium density and the elasticity properties change the amplitude depends on the energy carried by the wave, that is, the amplitude is proportional to the height of the wave (oscillation).
Consequently the amplitude of independent of the frequency because it depends on different factors.
Therefore when changing the amplitude the wavelength remains constant
the correct answer is b
Here, S = ut + 1/2 at²
381 = 0*t + 1/2 * 9.8 * t²
762/9.8 = t²
t = √77.75
t = 8.82 sec
In short, Your Answer would be 8.82 s
Hope this helps!
