Answer:
33.33 seconds
Explanation:
= Initial length pulled = 20 cm
b = Damping constant = 0.015 kg/s
k = Spring constant = 4 N/m
m = Mass of glider = 250 g
Time period is given by
Using exponential decay formula
Final amplitude = Initial times decay
The time taken is 33.33 seconds
Answer:
Explained.
Explanation:
Only the first question has been answered
In a period from left to right the nuclear charge increases and hence nucleus size is compressed. Thus, atomic radius decreases.
In transition elements, electrons in ns^2 orbital remain same which is the outer most orbital having 2 electrons and the electrons are added to (n-1) d orbital. So, outer orbital electron experience almost same nuclear attraction and thus size remains constant.
You actually sweating if the cooling part. you sweat so you can cool down.
It works by you putting leverage on one side makes more force go to the other side so if you put a crowbar in between a door and you push on one side the other will push the opposite side with more force<span />
