The question is incomplete, here is the complete question:

How many kWh of energy does a 650-W toaster use in the morning if it is in operation for a total of 6.0min ?

At a cost of 9.0 cents/kWh, estimate how much this would add to your monthly electric energy bill if you made toast four mornings per week (16 times per month).

Express your answer using two significant figures.

Answer:

$ 0.1 per month

Explanation:

We convert from Watt to kilowatt

650/1000 = 0.65KW

We convert from minutes to hour:

6/60= 0.1 hr

Convert cents to dollars

9/100 = $0.09

Energy cost in KWh= 0.65 × 0.1 × 0.09 ×16= $ 0.1 per month

Zinaida [17]

Answer:

Membrane potential

Explanation:

Membrane potential is describes the difference in electrical charge across a membrane.                                                                                                              

The difference in potential between exterior  and  interior of the  biological cell is known as Membrane potential.Generally it is denoted by  millivolts like mV and varies from -80 V to -40 V.

So the answer is Membrane potential

Anastaziya [24]

Answer:

The magnitude  of the electric field is 5.1 \times 10^{11}  \frac{N}{C}

Explanation:

Given:

Charge of electron q = 1.6 \times 10^{-19}C

Separation between two charges r = 5.3 \times 10^{-11} m

For finding the magnitude of the electric field,

   E= \frac{kq}{r^{2} }

Where k = 9 \times 10^{9}

   E = \frac{9 \times 10^{9} \times 1.6 \times 10^{-19} }{(5.3 \times 10^{-11} )^{2} }

   E = 5.1 \times 10^{11} \frac{N}{C}

Therefore, the magnitude  of the electric field is 5.1 \times 10^{11}  \frac{N}{C}

Use the graph of velocity versus time for an object to answer the question.
Pavel [41]

T<u>he statement which fairly compares segment 2 and segment 3 </u>is These represent equal periods of time, but the force during segment 2 is different than the force during segment 3.

Since segment 2 starts at t = 60 s and ends at t = 150 s, the time interval is Δt = 150 - 60 = 90 s.

Also, segment 3 starts at t = 150 s and ends at t = 240 s, the time interval is Δt = 240 - 150 = 90 s.

So, their time periods are the equal.

We notice that segment 2 is less steep than segment 3 this implies that the acceleration in each segment is different, since the acceleration is the slope of the graph.

Since force is determined by acceleration, this implies that the force on segment 2 is different form the force acting in segment 3.

So, we have equal time periods but different forces.

So, <u>the statement which fairly compares segment 2 and segment 3 </u>is These represent equal periods of time, but the force during segment 2 is different than the force during segment 3.
