Answer: P = 36.75W
The additional power needed to account for the loss is 36.75W.
Explanation:
Given;
Mass of the runner m= 60 kg
Height of the centre of gravity h= 0.5m
Acceleration due to gravity g= 9.8m/s
The potential energy of the body for each step is;
P.E = mgh
P.E = 60 × 9.8 × 0.5
PE = 294J
Since the average loss per compression on the leg is 10%.
Energy loss = 10% (P.E)
E = 10% of 294J
E = 29.4J
To calculate the runner's additional power
given that time per stride is = 0.8s
Power P = Energy/time
P = E/t
P = 29.4J/0.8s
P = 36.75W
Answer:
Gypsum
Explanation:
Gypsum is a soft sulfate mineral composed of Calcium Sulfate di-hydrate. It is widely used in composition of fertilizer. It is also known as land plaster. On adding gypsum to soil, the quality of soil is improved. It conditions the soil and adds nutrients. The properties of soil is improved. Hence, the correct answer is Gypsum.
Hope this helped:)

The for the next one the answer is "C"
I hope this helps. :)
Answer:
![\phi=1.56\times 10^{-5}\ Wb](https://tex.z-dn.net/?f=%5Cphi%3D1.56%5Ctimes%2010%5E%7B-5%7D%5C%20Wb)
Explanation:
Given that,
Emf, V = 22 mV
Number of turns in the coil us 519
Rate of change of current is 10 A/s.
We need to find the magnetic flux through each turn of the coil at an instant when the current is 3.70 A.
Let's find the inductance first. So,
![L=\dfrac{\epsilon}{(dI/dt)}\\\\L=\dfrac{0.022}{10}\\\\L=0.0022\ H](https://tex.z-dn.net/?f=L%3D%5Cdfrac%7B%5Cepsilon%7D%7B%28dI%2Fdt%29%7D%5C%5C%5C%5CL%3D%5Cdfrac%7B0.022%7D%7B10%7D%5C%5C%5C%5CL%3D0.0022%5C%20H)
We have,
,
is magnetic flux
![\phi=\dfrac{LI}{N}\\\\\phi=\dfrac{0.0022\times3.7}{519}\\\\\phi=1.56\times 10^{-5}\ Wb](https://tex.z-dn.net/?f=%5Cphi%3D%5Cdfrac%7BLI%7D%7BN%7D%5C%5C%5C%5C%5Cphi%3D%5Cdfrac%7B0.0022%5Ctimes3.7%7D%7B519%7D%5C%5C%5C%5C%5Cphi%3D1.56%5Ctimes%2010%5E%7B-5%7D%5C%20Wb)
So, the magnetic flux is
.
