The equivalent resistance of the three resistors when connected in parallel is:
Since the three resistors in this problem are identical, we can call R their resistance, and we can rewrite the previous equation as
And since we know the value of the equivalent resistance,
, we can find the value of R:
Now the problem asks us what is the equivalent resistance of the three resistors when they are connected in series. In this case, the equivalent resistance is just the sum of the three resistances, so
The magma is heated and becomes less dense by the core moving it toward the crust.
Option D.
<u>Explanation:</u>
Magma is a form of molten rock which might be partially molten or might be fully molten. Magma consists of silicate liquid.
This molten part of the rock is either ejected in the form of lava or this molten rock might move from upper layer of Earth to the lower layer of Earth. The crystals which are not molten which get transported into the magma, form bubbles and get separated.
The chemical change is are to water breaking down into hydrogen and oxygen.
Answer is D.
Answer:
The answer is 13 however make sure if they ask for a certain measurement like meter answer it by saying 13 meters.
Explanation:
This basically turns into basic algebra if you know the formula for work. The formula for work is W=F*d
Here are the variables that you know 650J=50N*d so you need d.
All you do is divide 650J by 50N and you get a total of 13 (meters since I don't know what they want you to put it in).
Answer:
Part a)
Part b)
Explanation:
Part a)
Angular speed of the pedal is changing from 60 rpm to 90 rpm in 10 s
so the angular acceleration is given as
so we will have
now the tangential acceleration of the pedal is given as
Part b)
Total angular displacement made by the sprocket in the interval of 10 s is given as
now length of the chain passing over it is given as
