What energy transformation takes place when you turn on a light
Answer:
From electrical energy to radiation
Explanation:
A light bulb converts electrical energy to light, which is nothing more than radiation. Don't regard radiation as a bad thing, this light is non-iodizing radiation, which does not have the possibility to alter our DNA, and thus it's safe.
The simplest example can be found in old lights (obsolete now because they are vastly inefficient). This lights were just resistors which turned electrical energy into heat. A very hot material reflects light in the form of radiation, as described above.
Technologies like LEDs are more complicated to explain.

How much work, in Newtons, is required to lift a 20.4-kg (45lb) plate from the ground to a stand that is 1.50 meters up?
ASAP PLS
Answer:
Explanation:
Work, U, is equal to the force times the distance:
U = F · r
Force needed to lift the weight, is equal to the weight: F = W = m · g
so:
U = m · g · r
= 20.4kg · 9.81 \(\frac{N}{kg}\) · 1.50m
= 35.316 \(\frac{N}{m}\)
= 35.316 W

What is the total execution time of this instruction sequence with only ALU-ALU forwarding? What is the speedup over a no-forwarding pipeline?
In this exercise, we are analyzing how data dependences impact the execution of instructions in a basic 5-stage pipeline. The instruction sequence we are using for this analysis includes the following instructions: or ri,r2,r3 or r2,r1, r4 or ri, ri, r2. a. The dependences and their types in this instruction sequence are as follows: - or ri,r2,r3 depends on nothing - or r2,r1,r4 depends on ri=r2 - or ri,ri,r2 depends on r2=r1
b. Assuming there is no forwarding, the hazards in this pipeline would be data hazards. To eliminate these hazards, we would need to insert nop instructions between the dependent instructions, which would increase the total execution time of the instruction sequence. c. Assuming there is full forwarding, the hazards in this pipeline would be resolved automatically without the need for any nop instructions. d. Without forwarding, the total execution time of this instruction sequence would be 750ps (250ps for each instruction). With full forwarding, the total execution time would be 570ps (190ps for each instruction). The speedup achieved by adding full forwarding to a pipeline that had no forwarding is 31.43%.
e. If there is ALU-ALU forwarding only (no forwarding from the MEM to the EX stage), we would need to insert nop instructions to eliminate the hazards. The nop instructions would need to be inserted between the dependent instructions, which would increase the total execution time of the instruction sequence. f. With only ALU-ALU forwarding, the total execution time of this instruction sequence would be 810ps (270ps for each instruction). The speedup over a no-forwarding pipeline would be -8%, meaning that there is a slowdown when using ALU-ALU forwarding only compared to having no forwarding at all.

On May 31, the Cash account of Tesla had a normal balance of $6,400. During May, the account was debited for a total of $13,600 and credited for a total of $12,900. What was the balance in the Cash account at the beginning of May
The balance in the Cash account at the beginning of May was $6,700.On May 31, the Cash account of Tesla had a normal balance of $6,400.
To determine the balance in the Cash account at the beginning of May, we need to consider the net effect of the debits and credits during the month. The normal balance of $6,400 at the end of May indicates that the account has a credit balance. From the given information, the total debits for May were $13,600 and the total credits were $12,900. To calculate the beginning balance, we subtract the net credits from the net debits: $13,600 - $12,900 = $700. Since the account has a credit balance, we subtract $700 from the ending balance of $6,400: $6,400 - $700 = $6,700, which was the balance in the Cash account at the beginning of May.

When calculating the Reynolds number (Re) of a flowing fluid, the fluid's inertia force is determined by multiplying the fluid's velocity by the internal pipe diameter, and the resulting ratio is then divided by the fluid's kinematic viscosity (viscous force per unit length).
The ratio of momentum (or inertia) to viscous forces is how the Reynolds number is commonly understood. At a moderate Reynolds number, a significant shift in fluid behavior takes place. When this happens, the flow stops being uniform and laminar and starts to fluctuate (turbulent). Density * D * Flow Speed/viscosity = vReynolds number. The units on the right side of the equation cancel out completely, leaving the Reynolds number without any units. It grows as the flow rate quickens and shrinks as the viscosity increases. When the Reynolds number is around 2300, turbulence begins to occur.

a) What is the solids concentration (in mg/L) in the sludge leaving the clarifier?
b) What mass of solids (in kg/y) is removed annually by the primary clarifier?
Answer:
a) 47500 mg/L
b) 5250366.444 kg/year
Explanation:
Given data:
suspended solids removal efficiency = 20%
Flowrate in the primary clarifier ( Q ) = 20 MGD ( change to Liters/day
Q = 20* 10^6 * 3.785412 Liters /day
settled concentration ( St ) = 950mg/L * 0.2 = 190 mg/L
amount of settled solid = Q * St
= ( 20* 10^6 * 3.785412 ) * 190 = 14384.5656 kg/day
∴ Amount going into sludge with a flowrate of 0.08 MGD = 14384.5656 kg/day
a) concentration of solid in sludge ( leaving the clarifier )
= amount of settled solid / flow rate out of the clarifier in liters/day
= 14384.5656 / ( 0.08 * 10^6 * 3.785412 )
= 0.0475 kg/L
= 47500 mg/L
b) Determine mass of solids that is removed annually
