Explanation:
The weight of an object on the surface of the earth is equal to the gravitational force exerted by the earth on the object.
which gives us an expression for the acceleration due to gravity <em>g</em> as
At a height h = R, the radius of a satellite's orbit is 2R. Then the acceleration due to gravity at this height is
Simplifying this, we get
The Universe is always expanding outwards
Total work done is 0.13 Joules
<h3>What is work done ?</h3>
The sum of the displacement and the component of the applied force of the object in the displacement direction is the work done by a force.
According to the given information
We need to find the work done
work done = force × distance
We are given,
force = 26 N
Distance = 0.0005 meter
hence ,
Work done = 26 × 0.005
= 0.13 Joules
Total work done is 0.13 Joules

Answer:
A) 0.1773
B)Right electrode is the positive one
Explanation:
THIS IS THE COMPLETE QUESTION
certain metal M forms a soluble sulfate salt M S04. Suppose the left half cell of a galvanic cell apparatus is filled with a 4.50 mM solution of M2SO4 and the right half cell with a 4.50 M solution of the same substance. Electrodes made of M are dipped into both solutions and a voltmeter is connected between them. The temperature of the apparatus is held constant at 20.0 °C. O left Which electrode will be positive? Oright x 5 ? What voltage will the voltmeter show? Assume its positive lead is connected to the positive electrode. Be sure your answer has a unit symbol, if necessary, and round it to 2 significant digits.
