Answer:
Explanation:
For discharge of capacitor in RC circuit , the relation is as follows
V is voltage across the capacitor , V₀ is maximum voltage across capacitor , λ is time constant and t is the time after which the voltage is recorded. During discharge this will also be voltage across resistance .
Taking log on both sides
lnV = lnV₀ -
Given equation
[lnV] = - .027 t + 2.5
Comparing these equation
λ = 37 s
time constant = 37 sec.
Answer:
Explanation:
The center of mass of the system (two girls) is constant, as the velocity of the center of mass of the system is also constant.
<u>The initial velocity of the system is zero, since both girls are at rest.</u> So the velocity of the total system at any point should be zero as well.
This is true, because there is no friction between the girls and the ground. Otherwise, the velocity of the center of mass wouldn't be constant.
Answer:
a=500/50 = 10 m S2
Explanation:F =m ⋅ a a = F/m a 500/50 = 10 m/S2
hope this help.
Answer:
So it floats
Explanation:
m =3893.40 /10 = 389.340kg (if i use g= 10 not 9.81 -use 9.81 if your syllabus says so)
v = 4.60 m cube
389.340/4.60 =84.64
as density less than that of water 90
so it floats
540 meters should be the answer
