Answer:
222.5 Gpa
Explanation:
From definition of engineering stress,
where F is applied force and A is original area
Also, engineering strain, where l is original area and is elongation
We also know that Hooke's law states that
Since A=20 mm* 20 mm= 0.02 m*0.02 m
F= 89000 N
l= 100 mm= 0.1 m
By substitution we obtain
Answer:
1) 739 copies (739.7260273972603).
2) 5000 copies.
Explanation:
27000/365 = 73.97260273972603 (Their daily wins). How much times $.10 is equal to 73.97260273972603?
I used a two step equation to get it.
- 0.10 * x = 73.97260273972603
- /0.10 = /0.10
- x = 739.7260273972603
They need to sell 739.7260273972603 copies a day to get 27000$ a year.
an equation (y = mx+b) can be
y = 739.7260273972603x
To earn a 500$ profit we need to do the same two-step equation but instead of 73.97260273972603 use 500.
- 0.10 * x = 500
- /0.10 = /0.10
- x = 5000
5000 copies needs to be sold to get a 500$ profit.
The last question I don't understand but I hope those 2 questions helped
Answer with Explanation:
The relation between power and energy is
Since the nuclear reactor operates at 1200 MW throughout the year thus the energy produced in 1 year equals
Now from the energy mass equivalence we have
where
'c' is the speed of light in free space
Thus equating both the above values we get
Since it is given that 1 kg of mass is 34% effective thus the mass reuired for the reactor is
Thus 1.235 kg of nuclear fuel is reuired for operation.
