Answer:
The value of the constant k is 2
Explanation:
We have the equation of the velocity = kt² , where k
is constant and t is the time in second
The particle's position at = 0 is
= -9 m
The particle's position at = 3 s is
= 9 m
We need to find the value of the constant k
The relation between the velocity and the displacement in a particular
time is x =
Remember in integration we add power by 1 and divide the expression
by the new power
→ x =
c is the constant of integration to find it substitute the initial value of x
and t in the equation of x
→ = 0 ,
= -9 m
→ -9 = k (0)³ + c
→ -9 = c
Substitute the value of c in the equation of x
→ x = k t³ - 9
To find k substitute the values of = 3 s ,
= 9 m
→ 9 = k (3)³ - 9
→ 9 = (27) k - 9
→ 9 = 9 k - 9
Add 9 to both sides
→ 18 = 9 k
Divide both sides by 9
→ k = 2
<em>The value of the constant k is 2</em>
Resistance of our body is given as
voltage applied across the body is
now by ohm's law current pass through our body is given by
So current from our body will be 4 * 10^-3 A
