An office heater puts out 2050 btus of energy in the form of heat per hour. given that 1 btus =1.055 kj, how many megajoules of
ivolga24 [154]
<span>Assuming continuous operation (24/7), we can say that

Energy produced : Energy per hour * 24 (number of hours in a day) - 365 (number of days in a year.

Energy per hour: 2050 * 1.055 = 2162.75 kg.

So, we proceed to calculate the results

E: 2162.75 * 24 * 365 = 18,945,690 kj per year.

Now, we transform kj to megajoule, remembering that kilo is 10*3 and mega is 1'*6, so we divide the result by 1,000 in order to get the results in megajoules, and the answer would be:

18,945.69 megajoules can be produced per year.</span>

A 400.0 ohm resistor has a potential difference of 20.0 volts. What is the magnitude of the power dissipated by the resistor
Sergio [31]

P=IV, where P is power, I is resistance, and V is voltage.  Plug in and solve:

P=400(20)

P=8000W

Hope this helps!!

The mass of M1 = 12 Daltons and it has a speed of v1 = 200 m/s. The mass of M2 = 4 Daltons. What was the total momentum of the s
svet-max [94.6K]

Answer:

The total momentum is  p__{T }} =(2400  -4 v_2) \ Dalton \cdot m/s

Explanation:

The diagram illustration this  system is shown on the first uploaded image (From physics animation)

From the question we are told that

     The mass of the first object is M_1 =  12 \ Dalton

      The speed of the first mass is v_1 =  200 \ m/s

      The mass of the second object is  M_2 =  4 \ Dalton

      The speed of the second object is  assumed to be  - v_2

The total momentum of the system is the combined momentum of both object which is mathematically represented as

           p__{T }} = M_1 v_1 + M_2 v_2

   substituting values

            p__{T }} = 12 * 200 + 4 * (-v_2)

            p__{T }} =(2400  -4 v_2) \ Dalton \cdot m/s
