1) If Shagreen bought the energy star refrigerator for $1800 and saved

Physics
1 answer:
MaRussiya [10]3 years ago
8 0

Answer:

9

Explanation:

Shagreen bought the energy star generator for $1800

She saves $200/every year

Therefore the number of years it would take for her to save that amount can be calculated as follows

= 1800/200

= 9

Hence it would take 9 years to save up the money

A typical rechargeable deep-cycle battery for an electric trolling motor (fishing boat) delivers 10A of current at a voltage of
Oksi-84 [34.3K]

Answer:

a) 360 kQ

b) 4.32 MJ

c) 1200 W-h

Explanation:

a) The definition of the current is.

I= \frac{Q}{t}

having a count that 10 hours = 36.000 s

Q = I*t

Q = 36000*10 = 360.000 [Q]

b) The definition of the Energy in power terms is.

E = \int\limits^{t}_{0} {P} \, dt

and the definition of power is:

P = V*I = 12 * 10 = 120 [W]

replacing in the energy formula.

E = \int\limits^{36.000}_{0} {120} \, dt

solving the integral, have into account that t is in seconds.

E=P*t=120*36000=4.320.000=4.32 [MJ]

c) The energy in W-h, we can find it multiplying power by hours

E = P*t =120*10 = 1200 W-h.

If the moon is half full on November 2, on approximately what date will it next become full?
anyanavicka [17]
The complete cycle of lunar phases has a period of 29.531 days.

You've described two phases that are separated by 1/4 of the
complete cycle.

If the moon is exactly at First Quarter (half-full and getting bigger)
at, let's say, 12:00 Noon on November 2 where you are, then it will
be Full after

                29.531 days / 4 =  7 days 9 hours 11 minutes .

That's  9:11 PM on November 9 .
