Answer:
0.0196 j
Explanation:
i) The formula for kinetic energy is as follows: 0.5*m*v^2
ii) Since we have all the values all that's left is to plug them into the equation
iii) First, WE MUST, Convert grams into kgs as this is the SI unit of mass so 2.45/1000
iv) All that's left now is to plug it into the equation so:
0.5* (s.45/1000)*(4^2)
v) Lastly we add the unit joules at the end as we're talking about energy
Hope this was useful! :)
I Think It's C because that's what nuclear plants let off which means its a waste.
Answer:
1.) Radar
2.) Cancer Treatment
4.) Cooking
Explanation:
Microwaves are a type of electromagnetic radiations, like radio waves, X-rays, Gamma Rays, ultraviolet radiation. Microwaves has a wide range of applications. It has frequency range 1GHz to 300GHz and has smaller wavelengths. As microwaves do not bend by any obstacles coming in their path, So, it can be used in radar. In cancer treatment, it is used to increase the temperature of tumor cells by high-power microwaves, results in turns cell membrane damage, which in results destruction of cancer cells. In cooking, microwave heat food like the sun rays your face i.e by means of radiation. It increases the energy of molecules inside food, which results in cooking or heating the food.
There's no such thing as a "cubic gallon". A 'gallon' is already a unit of volume,
only without the word 'cubic' in it.
If you like to play with different units of measure, here are a few conversions:
1 gallon = 231 cubic inches
1 cubic foot = 1,728 cubic inches = about 7.4805 gallons
1 cubic meter = 1,000 liters = 1 million cubic centimeters = about 264.17 gallons
We can make an electromagnet stronger by doing these things:<span>wrapping the coil around an iron core.adding more turns to the coil.<span>increasing the current flowing through the coil.</span></span>
