<u>Estimation of Atoms in Human Body</u>
We generally evaluate the amount of elements, liquid, or solid bones in a human body but, we can relate these counts to the atomic level as well. Talking about the approximate amount of Hydrogen, Oxygen and Carbon that we carry in our body, they all make 99% of it neglecting 1% of trace elements.
On the basis of this calculation, we can say that a human body of weight 70 kg has around
atoms that are differentiated as 2/3 of hydrogen atoms, 1/4 of Oxygen and only 1/3 of Carbon atoms in the total count.
Answer:
2.177088 * 10^-8 N
Explanation:
solution;
mass(m1) = 1 * 10 kg
mass(m2) = 8 * 102 kg
distance(d) = 5m
universal gravitational constant (G) =6.67 * 10^-11
we know that,
gravitational force = (G*m1*m2)/d^2
=((6.67 *10^-11) *(1 *10)*(8 *102))/5^2
=(5.44272 * 10^-7)/25
=2.177088 *10^-8
Gravitational force = 2.177088 * 10^-8
Answer:
EMF = 108.3 Volts
Explanation:
As per Faraday's law of electromagnetic induction we know that rate of change in magnetic flux will induce EMF in closed loop
So it is given as
![EMF = N\frac{d\phi}{dt}](https://tex.z-dn.net/?f=EMF%20%3D%20N%5Cfrac%7Bd%5Cphi%7D%7Bdt%7D)
![EMF = N\frac{BA - 0}{\Delta t}](https://tex.z-dn.net/?f=EMF%20%3D%20N%5Cfrac%7BBA%20-%200%7D%7B%5CDelta%20t%7D)
now we know that
N = 50 turns
B = 1.5 T
A = 0.325 m^2
![\Delta t = 0.225 s](https://tex.z-dn.net/?f=%5CDelta%20t%20%3D%200.225%20s)
now we have
![EMF = (50)(\frac{1.5\times 0.325}{0.225})](https://tex.z-dn.net/?f=EMF%20%3D%20%2850%29%28%5Cfrac%7B1.5%5Ctimes%200.325%7D%7B0.225%7D%29)
![EMF = 108.3 Volts](https://tex.z-dn.net/?f=EMF%20%3D%20108.3%20Volts)
A particle is moving along a projectile path where the initial height is 96 feet with an initial speed of 16 feet per second.
let's find the maximum height<span>of the particle
</span><span>s(t)=−16<span>t2</span>+16t+96</span><span>
</span><span>s(1/2)=−16(1/2<span>)2</span>+16(1/2)+96=−16(1/4)+8+96=−4+8+96=100
Therefore the answer is 100

A vector is any quantity that has magnitude and direction. A scalar is any quantity that has magnitude but has no direction.Displacement and velocity are vectors, distamce and speed are scalars.
