6 0

Answer:

f = 0.05Hz

Explanation:

Look at the graph. You can see that the wave complete one cycle in 20 seconds, so we can say that the period is 20s.

T = 20

frequency is just the inverse the period so

f = 1/T = 1/20 = 0.05Hz

An automotive Battery is rated at120 A-h. This means that under certain test conditions, it canoutput 1 A at 12 V for 120 hours.
Hitman42 [59]

Answer:

Part A:

In W-h:

Energy Stored=1440 W-h

In Joules:

Energy Stored=5.184*10^6Joules\\Energy Stored=5.184 MJ

Part B:

In W-h:

Energy left=240 W-h

In Joules:

Energy left= 8.64*10^5 J

Explanation:

Part A:

We are given rating 120A-h and voltage 12 V

Energy Stored= Rating*Voltage              (Gives us units W-h)

Energy Stored=120A-h*12V

Energy Stored=1440 W-h

Converting it into joules (watt=joules/sec)

Energy Stored=1440 Joules * \frac{3600sec}{h}h

Energy Stored=5184000 Joules

Energy Stored=5.184*10^6Joules\\Energy Stored=5.184 MJ

Part B:

Energy used by lights for 8h=150*8

Energy used by lights for 8h=1200W-h

Energy left= Energy Stored(Calculated above)- Energy used by lights for 8h

Energy left=1440-1200

Energy left=240 W-h

Energy left=240 Joules * \frac{3600sec}{h}h

Energy left=864000 Joules

Energy left= 8.64*10^5 J

azamat

Answer:

The couples are not all on one axis or plane for that matter but if the A and B connector had to be specified it would go by the yz axis diagonal to the x axis with a magnitude of about 15. The direction of the axis would be pointed up to the second quadrant. Hope this was helpful

Mademuasel [1]

Answer:

1) The ethical act Amy should display is to open the Email since it came in through her personal inbox. However, further action should not be taken since ordinarily opening the mail will not disclose or corrupt her system either locally of her system on the server and web space.

2)  If such email came in, the first action i will take is to open the mail then take a pause to read through the instruction because most scam or malware comes with an array of further instructions.

After carefully reading through, i will call up Davey to confirm if he sent such mail which answer will obviously be a No and in the case where i am unable to get a call through to Davey, i will immediately delete the mail from my inbox to avoid the mistake of clicking any embedded link within the mail.
