Answer:
Sun
Explanation:
Any asteroid in space is a celestial body. Classification of Celestial Bodies. A star is a form of a celestial object made up of a shining spheroid of plasma held together by its own gravity. The nearby star to Earth is the Sun.
Answer:
The strength of the electric field is
.
Explanation:
Given that,
Speed ![v= 5.05\times10^{5}\ m/s](https://tex.z-dn.net/?f=v%3D%205.05%5Ctimes10%5E%7B5%7D%5C%20m%2Fs)
Time ![t= 3.90\times10^{-7}\ s](https://tex.z-dn.net/?f=t%3D%203.90%5Ctimes10%5E%7B-7%7D%5C%20s)
Angle = 45°
We need to calculate the acceleration
Using equation of motion
![v = u+at](https://tex.z-dn.net/?f=v%20%3D%20u%2Bat)
![5.05\times10^{5}=0+a\times3.90\times10^{-7}](https://tex.z-dn.net/?f=5.05%5Ctimes10%5E%7B5%7D%3D0%2Ba%5Ctimes3.90%5Ctimes10%5E%7B-7%7D)
![a =\dfrac{5.05\times10^{5}}{3.90\times10^{-7}}](https://tex.z-dn.net/?f=a%20%3D%5Cdfrac%7B5.05%5Ctimes10%5E%7B5%7D%7D%7B3.90%5Ctimes10%5E%7B-7%7D%7D)
![a=1.29\times10^{12}\ m/s^2](https://tex.z-dn.net/?f=a%3D1.29%5Ctimes10%5E%7B12%7D%5C%20m%2Fs%5E2)
We need to calculate the strength of the electric field
Using relation of newton's second law and electric force
![F= ma=qE](https://tex.z-dn.net/?f=F%3D%20ma%3DqE)
![ma = qE](https://tex.z-dn.net/?f=ma%20%3D%20qE)
![E=\dfrac{ma}{q}](https://tex.z-dn.net/?f=E%3D%5Cdfrac%7Bma%7D%7Bq%7D)
Put the value into the formula
![E=\dfrac{1.67\times10^{-27}\times1.29\times10^{12}}{1.6\times10^{-19}}](https://tex.z-dn.net/?f=E%3D%5Cdfrac%7B1.67%5Ctimes10%5E%7B-27%7D%5Ctimes1.29%5Ctimes10%5E%7B12%7D%7D%7B1.6%5Ctimes10%5E%7B-19%7D%7D)
![E=1.35\times10^{4}\ N/C](https://tex.z-dn.net/?f=E%3D1.35%5Ctimes10%5E%7B4%7D%5C%20N%2FC)
Hence, The strength of the electric field is
.
C. nervous system, because its triggers
I believe the answer is B. that's where the asetroid belt is.
