We are asked to write an equation of the sphere with center (-3,2,5) and radius 4.
We know that equation of a sphere with radius 'r' and center (h,k,l) at is in form:
(x-h)²+(y-k)²+(z-l)²=r²
Since center of the given sphere is at point (-3,2,5) , so we will substitute h=-3,k=2 ,l=5 and r=4 in above equation as:
(x-(-3))²+(y-2)²+(z-5)²=4²
(x+3)²+(y-2)²+(z-5)²=16
Therefore, our required equation would be (x+3)²+(y-2)²+(z-5)²=16
To find the intersection of our sphere with the yz-plane, we will substitute x=0 in our equation as
(0+3)²+(y-2)²+(z-5)²=16
9+(y-2)²+(z-5)²=16
9-9+(y-2)²+(z-5)²=16-9
(y-2)²+(z-5)²=7

Find the power that is absorbed or supplied by the network elements in fig p1.32
The power that is absorbed or supplied by the network elements is 32 W
The quantity of energy moved or converted per unit of time is known as power in physics. The watt, or one joule per second, is the unit of power in the International System of Units. Power is also referred to as activity in ancient writings. A scalar quantity is power.
Looking at diagram (a), we will analyze each element separately.
P(2A) = -20(2)
(Negative because the current is entering the negative terminal)
P(2A) = -40W
Which means 40W of power is supplied by the 2A element.
P1 = (6)(2)
P1 = 12W
Therefore, 12W of power is absorbed by element 1.
P(14v) = (14)(2)
P(14v) = 28W
Thus, 28W are absorbed by the 14v element.
We will now look at diagram (b).
P(4A) = (16)(−4)
P(4A) = −64W

The answer for sub question A) calculate the percent uncertainty in the distance is 0.059%.
The answer for sub question B) calculate the uncertainty in the elapsed time is 9,012 s
The answer for sub question C) what is the average speed in meters per second is 4.681 m/s
The answer for sub question D) what is the uncertainty in the average speed is 0.0032 m/s
How are the answers calculated?To calculate the percentage of uncertainty of distance we have uncertainty = 25 m and distance = 42.188 km which is 42188 m.
Now [tex]\frac{25}{42188}[/tex] x 100% = 0.059%
To calculate time elapsed, we have the following data:

A certain reaction has an activation energy of 43.41 kj/mol. at what kelvin temperature will the reaction proceed 7.50 times faster than it did at 317 k?
The temperature required to increase the reaction rate by 7.50 times will be 332.63 K .
The speed at which a chemical reaction proceeds is known as the reaction rate.
We are given that ,
The activation energy = E = 43.41 kj/mol
Initial temperature = T₁ = 317 k
Therefore we can write as, the temperature at which reaction has 7.50 times faster than at 317 K be T₂ . Then the rate of a reaction increases because the rate constant increases with temperature.
The relation between temperatures, rate constants, and activation energy is given as,
(k₁/k₂) = E/R [(1/T₁ ) - (1/T₂)]
Where, k₁ is rate constant at temperature T₁ and k₂ is rate constant at temperature T₂ & R is gas constant having value 8.314 j/kmol .
Thus putting all the given values in above equation then we get,
7.50k/k = (434100 j/mol)/(8.314j/kmol)[(1/317k) - (1/T₂)]
7.50 = 52213.1344 k [ 0.00315 k⁻¹ - 1/T₂]
1/T₂ = 0.00315 K⁻¹ - (7.50/52213.1344)
T₂ = 332.63 K
Therefore the temperature required to increase the reaction rate by 7.50 times is given as T₂ = 332.63 K

According to the newton's law of viscosity, the proportional constant that satisfies the relation between the shear strain rate and the velocity gradient is the Viscosity coefficient.
What is Viscosity coefficient ?
The fluid's resistance to flowing is measured by the coefficient of viscosity. The viscosity of a gas is often lower than that of a liquid. Fluidity is the opposite of viscosity. A liquid with a high viscosity thus has a poor fluidity. There are two forms of viscosity that are frequently used: dynamic viscosity and kinematic viscosity. Dynamic viscosity and kinematic viscosity are connected by the equation dynamic viscosity = kinematic viscosity, where is the density of the fluid. Centipoise is the definition of dynamic viscosity. Kinematic viscosity is measured in centistoke, whereas fluid density is measured in g/cc. One centistoke is determined by dividing one centipoise by one g/cc. Darcy's law uses dynamic viscosity to determine the rate of fluid flow in porous material.
