Answer:
9.801 m/s²
Explanation:
t = Time taken
u = Initial velocity
v = Final velocity = 39 ft/s
s = Displacement = 720 cm = 7.2 m
a = Acceleration
Converting to m/s
![39\ ft/s=\frac{39}{3.281}=11.88\ m/s](https://tex.z-dn.net/?f=39%5C%20ft%2Fs%3D%5Cfrac%7B39%7D%7B3.281%7D%3D11.88%5C%20m%2Fs)
Equation of motion
![v^2-u^2=2as\\\Rightarrow a=\frac{v^2-u^2}{2s}\\\Rightarrow a=\frac{11.88^2-0^2}{2\times 7.2}\\\Rightarrow a=9.801\ m/s^2](https://tex.z-dn.net/?f=v%5E2-u%5E2%3D2as%5C%5C%5CRightarrow%20a%3D%5Cfrac%7Bv%5E2-u%5E2%7D%7B2s%7D%5C%5C%5CRightarrow%20a%3D%5Cfrac%7B11.88%5E2-0%5E2%7D%7B2%5Ctimes%207.2%7D%5C%5C%5CRightarrow%20a%3D9.801%5C%20m%2Fs%5E2)
Acceleration of the ball is 9.801 m/s²
Answer:
J of energy is available through fusion .
Explanation:
let us consider weight of the human body on an average be 70 kg .
since 0.8% of mass is used to convert into energy = ![70\times \frac{0.8}{100} =0.56kg](https://tex.z-dn.net/?f=70%5Ctimes%20%5Cfrac%7B0.8%7D%7B100%7D%20%3D0.56kg)
since according to einstein mass energy equation
![E=MC^{2}](https://tex.z-dn.net/?f=E%3DMC%5E%7B2%7D)
![E=0.56\times 9\times10^{16}\\ =5.04\times10^{16}J](https://tex.z-dn.net/?f=E%3D0.56%5Ctimes%209%5Ctimes10%5E%7B16%7D%5C%5C%20%3D5.04%5Ctimes10%5E%7B16%7DJ)
Nobody in Cosmology or the Bible ever said that anything came from "nothing".

Explanation:
Answer:
0.05 V/m
Explanation:
For a uniform electric field, electric field strength and potential difference are related by
![E=\frac{\Delta V}{d}](https://tex.z-dn.net/?f=E%3D%5Cfrac%7B%5CDelta%20V%7D%7Bd%7D)
where
E is the electric field strength
is the potential difference
d is the distance between the two points
Here we have
![\Delta V= 0.50 mV=5\cdot 10^{-4}V](https://tex.z-dn.net/?f=%5CDelta%20V%3D%200.50%20mV%3D5%5Ccdot%2010%5E%7B-4%7DV)
![d=1.0 cm=0.01 m](https://tex.z-dn.net/?f=d%3D1.0%20cm%3D0.01%20m)
So, the electric field strength is
![E=\frac{5\cdot 10^{-4} V}{0.01 m}=0.05 V/m](https://tex.z-dn.net/?f=E%3D%5Cfrac%7B5%5Ccdot%2010%5E%7B-4%7D%20V%7D%7B0.01%20m%7D%3D0.05%20V%2Fm)
