Answer:
.192 kg x m^2
Explanation:
<em>I=</em> mass of a times radius of a squared + mass of b times radius of b squared +...
<em>I= </em>.6 kg x .4m^2 + .6 kg x .4m^2
= .192 kg x m^2
Hope this helps :)
The answer to that question is A
Answer:
Explanation:
<em><u>Considering the density & specific heat capacity of coffee to be equal to that of water.</u></em>
<em><u>GIVEN:</u></em>
- density
- specific heat
- mass of coffee,
- initial temperature of coffee,
- final temperature of coffee,
- power rating of oven,
- time taken to reach the final temperature,
<u>Heat released by the coffee to come to 60°C:</u>
\ J[/tex]
<u>Now the energy used by the oven in the given time:</u>
Now the efficiency:
It's important to know that diffraction gratings can be identified by the number of lines they have per centimeter. Often, more lines per centimeter is more useful because the images separation is greater when this happens. That is, the distance between lines increases.
<h2>Therefore, the answer is 2.</h2>
I think the answer is periodic motion.
