Here,
height at failure, h1 = 525 m,
upward acceleration, a = 2.25 m/s^2,
velocity = v m/s,
<span>
SO, </span>
<span>
v^2 = 2*a*h = 2*2.25*525 = 2362.5 </span>
Now, acceleration, g = 9.8 m/s^2,
<span>
SO, </span>
<span>
heigt, h1 = v^2/2g = 2362.5 / 2*9.8 = 120.54 meters </span>
Hence,
<span>
a) </span>
Total height = 525+120.54 = 645.54 meters
b)
<span>time, for h1, t = v/g = sqrt(2362.5)/9.8 = 4.96 sec

Answer:
is it 20kg. Two opposing forces pushing onto each other
Answer:
0.0133A
Explanation:
Since we have two sections, for the Inductor region there would be a current
. In the case of resistance 2, it will cross a current
Defined this we proceed to obtain our equations,
For
,
![\frac{di_1}{dt}+i_1R_1 = V](https://tex.z-dn.net/?f=%5Cfrac%7Bdi_1%7D%7Bdt%7D%2Bi_1R_1%20%3D%20V)
![I_1 = \frac{V}{R_1} (1-e^{-\frac{R_1t}{L}})](https://tex.z-dn.net/?f=I_1%20%3D%20%5Cfrac%7BV%7D%7BR_1%7D%20%281-e%5E%7B-%5Cfrac%7BR_1t%7D%7BL%7D%7D%29)
For
,
![I_2R_2 =V](https://tex.z-dn.net/?f=I_2R_2%20%3DV)
![I_2 = \frac{V}{R_2}](https://tex.z-dn.net/?f=I_2%20%3D%20%5Cfrac%7BV%7D%7BR_2%7D)
The current in the entire battery is equivalent to,
![i_t = I_1+I_2](https://tex.z-dn.net/?f=i_t%20%3D%20I_1%2BI_2)
![i_t = \frac{V}{R_2}+\frac{V}{R_1} (1-e^{-\frac{R_1t}{L}})](https://tex.z-dn.net/?f=i_t%20%3D%20%5Cfrac%7BV%7D%7BR_2%7D%2B%5Cfrac%7BV%7D%7BR_1%7D%20%281-e%5E%7B-%5Cfrac%7BR_1t%7D%7BL%7D%7D%29)
Our values are,
![V=1V](https://tex.z-dn.net/?f=V%3D1V)
![R_1 = 95\Omega](https://tex.z-dn.net/?f=R_1%20%3D%2095%5COmega)
![L= 1.5*10^{-2}H](https://tex.z-dn.net/?f=L%3D%201.5%2A10%5E%7B-2%7DH)
![R_2 =360\Omega](https://tex.z-dn.net/?f=R_2%20%3D360%5COmega)
Replacing in the current for t= 0.4m/s
![i=\frac{1}{360}+\frac{1}{95}(1-e^{-\frac{95*0.4}{1.5*10^{-2}}})](https://tex.z-dn.net/?f=i%3D%5Cfrac%7B1%7D%7B360%7D%2B%5Cfrac%7B1%7D%7B95%7D%281-e%5E%7B-%5Cfrac%7B95%2A0.4%7D%7B1.5%2A10%5E%7B-2%7D%7D%7D%29)
![i= 0.0133A](https://tex.z-dn.net/?f=i%3D%200.0133A)
![i_1 = 0.01052A](https://tex.z-dn.net/?f=i_1%20%3D%200.01052A)
Answer:
energy per unit charge
Explanation:
EMF is energy per unit charge and has unit joule/ coulomb, where joule is unit of energy and coulomb is the unit of charge.
