Explanation:
Strain energy is defined as the energy stored in a body due to deformation. The strain energy per unit volume is known as strain energy density and the area under the stress-strain curve towards the point of deformation. When the applied force is released, the whole system returns to its original shape.
Answer:
P = 942.54 W
Explanation:
Given:
Temperature, T = 310 K
mass, m = 70 kg
Now from the stefan's law,
we have the formula
P = σAT⁴
where,
P = radiate energy
σ = Stefan's constant = 5.67 × 10⁻⁸ W/(m² K⁴)
A = Area of the body
Average surface area for a human body = 1.8 m²
T = Temperature
on substituting the values we get,
P = 5.67 × 10⁻⁸ × 1.8 × 310⁴
or
P = 942.54 W
Answer:

c
Explanation:
From the question we are told that
The mass of the bag is 
The normal force experienced is 
The maximum acceleration of the bag is 
Generally this normal force experience by the bag is mathematically represented as
=> 
=> 
=> ![\theta = cos^{-1}[0.9183]](https://tex.z-dn.net/?f=%5Ctheta%20%20%3D%20cos%5E%7B-1%7D%5B0.9183%5D)
=>
Generally for the bag not to slip , it means that the frictional force is equal to the sliding force
Hence 
is mathematically represented as
While 
is mathematically represented as
So
=> 
=>
Generally from the workdone equation we have that
Here 
is the work done by friction which is mathematically represented as
Here s is the distance covered by the bag
is zero given that velocity at rest is zero
and
so
=> 
substituting 2.55 m/s for v_i and 0.350 for \mu_k we have that
=>
Bit of an odd question. Power Plants are known to use water-powered turbines to generate electricity, but can also make use of nuclear fission.
Answer:
b-testing
Explanation:
First would be observation/research. Then the hypothesis. After that you would test your theory, conduct experiments. And finally, your conclusion- what you got from the whole process basically.
Hope this helps.
