Albert Einstein, in his theory of special relativity, determined that the laws of physics are the same for all non-accelerating observers, and he showed that the speed of light within a vacuum is the same no matter the speed at which an observer travels
Yes, this is certainly ugly and scary.
Here's how to go about it:
-- Take the two resistors in the middle ... the 9 and the 8 .
They're in parallel.
Their equivalent resistance is something like 4.24 ohms. Whatever.
-- Take the two resistors around the outside on the right ... the 4 and the 6 .
Together, in series, they're equivalent to 10 ohms.
-- That 10 ohms is in parallel with the ~4.24 ohms in the box.
Now you have something like 2.98 ohms, all to the right of the 3 on top.
-- That 2.98 is in series with the 3.0 on top.
So there's 5.98 ohms.
-- The 20.0 is in parallel with the 5.98 ohms.
So that's about 4.6 ohms equivalent between 'A' and 'B'.
That's just off the top of my head. I won't sharpen it down
any further than that, because it's only 5 points, and you
should be able to do it now, using this approach.
This imply that the force applied by the gravity of the earth on the person, is equal to the force applied by the person on the earth.
According to the Newton's third law, for every force there is an equal reaction force, in the case of person standing on the earth, the gravity of the earth pulls the person by the same magnitude as the force applied by the person on the earth (which is equal to the weight of the person)..
The size of the star defines wither of not it is a dwarf star, or a red giant.
Answer:
-47 J
Explanation:
Given that,
Heat loss = -76 J (negative for loss)
Work done by the surroundings = -29 J
We need to find the change in internal energy of a system.
The first law of thermodynamics is given by :
W is work done by the system
Putting all the values,
Hence, the change in internal energy is -47 J.
