Moving the electron away from the nucleus requires energy, so the electrons in the outer shell will have more energy than ones in the inner shell. Electrons always have a charge of -1, so the charge in the inner and outer shell will be the same. Therefore the answer is 3
Answer:
38.5 L
Explanation:
For this question, we can use
V1/T1=V2/T2
where
V1 (initial volume)= 35 L
T1 (initial temperature in Kelvin)= 303 K
V2(final volume)= ?
T2 (final temperature in Kelvin)= 333K
Since we are trying to find the final volume, we can rearrange the equation to say
V2= (V1/T1) × T2
V2= (35/303)×333
V2= 38.5 L
Answer: it will gain them by multiplying the electrons

Answer : The correct option is A: 20 km/h, B: 10 km/h
Explanation :
Speed : It is defined as the distance traveled per unit time.
Formula used:
![S=\frac{d}{t}](https://tex.z-dn.net/?f=S%3D%5Cfrac%7Bd%7D%7Bt%7D)
where,
S = speed
d = distance
t = time
First we have to calculate the speed of vehicle A.
Given:
Distance of vehicle A = 50 km
Time of vehicle A = 2.5 hr
Now putting all the given values in the above formula, we get:
![S=\frac{50km}{2.5hr}=20km/hr](https://tex.z-dn.net/?f=S%3D%5Cfrac%7B50km%7D%7B2.5hr%7D%3D20km%2Fhr)
Now we have to calculate the speed of vehicle B.
Given:
Distance of vehicle B = 50 km
Time of vehicle B = 5 hr
Now putting all the given values in the above formula, we get:
![S=\frac{50km}{5hr}=10km/hr](https://tex.z-dn.net/?f=S%3D%5Cfrac%7B50km%7D%7B5hr%7D%3D10km%2Fhr)
Therefore, the speed of vehicle A and B is 20 km/hr and 10 km/hr respectively.
