ANSWER: 1.6N (forth option)
EXPLANATION:
E= Force x displacement
69=F(42)
69/42 = F
F=1.64 N
Answer : 1.6N
First, we need to find the number of protons, which is the total mass divided by the mass of one proton:
![N= \frac{m}{m_p}= \frac{1.0 kg}{1.67 \cdot 10^{-27} kg}=6.0 \cdot 10^{26}](https://tex.z-dn.net/?f=N%3D%20%5Cfrac%7Bm%7D%7Bm_p%7D%3D%20%5Cfrac%7B1.0%20kg%7D%7B1.67%20%5Ccdot%2010%5E%7B-27%7D%20kg%7D%3D6.0%20%5Ccdot%2010%5E%7B26%7D%20%20%20)
protons
Then, the total charge is the number of protons times the charge of a single proton:
It's either staying there or is going at the same pace
Answer:
If there was no air resistance
Explanation:
We know that free fall is a unique motion in which gravity only works on one object. Objects that are said to be free-falling do not experience a significant force of air resistance; They come under the sole effect of gravity. Under such conditions, all objects fall under the same acceleration, regardless of their mass.
