Explanation:
Speed = 10 and miles = 5
(a) Speed + 12 – miles * 2
10 + 12 - 5 × 2
= 12
(b) speed + miles × 3
10 + 5 × 3
= 25
(c) (speed + miles) × 3
(10 + 5) × 3
= 45
(d) speed + speed × miles + miles
10 + 10 × 5 + 5
= 65
(e) (10 – speed) + miles / miles
(10 - 10) + 5/5
= 1
Therefore, this is the required solution.

The complete question is as follows: At 700 K, decomposes to carbon and chlorine. The Kp for the decomposition is 0.76.
Find the starting pressure of at this temperature that will produce a total pressure of 1.1 atm at equilibrium.
Answer: The starting pressure of is 0.79 atm.
Explanation:
The equation for decomposition of is as follows.
Let us assume that initial concentration of is 'a'. Hence, the initial and equilibrium concentrations will be as follows.
Initial: a 0 0
Equilibrium: (a - x) 0 2x
Total pressure = (a - x) + 2x = a + x
As it is given that the total pressure is 1.1 atm.
So, a + x = 1.1
a = 1.1 - x
Now, expression for equilibrium constant for this equation is as follows.
Hence, the value of 'a' is calculated as follows.
a + x = 1.1 atm
a = 1.1 atm - x
= 1.1 atm - 0.31 atm
= 0.79 atm
Thus, we can conclude that starting pressure of is 0.79 atm.

Answer:
Explanation:
Initial magnetic flux = magnetic field x area
= 4.4 x 5 x 10⁻³
= 22 x 10⁻³ weber
Final magnetic flux
= 1.32 x 5 x 10⁻³
= 6.6x 10⁻³ weber
change in magnetic flux = 15.4 x 10⁻³
emf induced = change in flux / time
= 15.4 x 10⁻³ / 22 x 10⁻³
= .7 V
current in bracelet = emf / resistance
= .7 / .02
= 35 A
b )
power = volt induced x current
= .7 x 35
= 24.5 W .
