Answer:
On moon time period will become 2.45 times of the time period on earth
Explanation:
Time period of simple pendulum is equal to 
....eqn 1 here l is length of the pendulum and g is acceleration due to gravity on earth
As when we go to moon, acceleration due to gravity on moon is 
times os acceleration due to gravity on earth
So time period of pendulum on moon is equal to
--------eqn 2
Dividing eqn 2 by eqn 1
So on moon time period will become 2.45 times of the time period on earth
We can see the image in most detail that having 400x magnification as compared to 100x.
<h3>What is magnification?</h3>
Magnification is the process in which the size of an object is enlarging but not physical size of something. Those instruments having high magnification power can shows us the image larger and due to which we can see that image clearly.
So we can conclude that we can see the image in most detail that having 400x magnification.

why does the baseball have to be autographed?
Density(rho) = m/v
(1.3)/((3.2)(17.1)(3.8))
since density is given in kg/m^3 you should convert the blocks dimensions to meters
1.3/(0.032*0.038*0.171)
plugging in these numbers would give you the density
1.3/0.000208
6250
with sigfigs= 6300kg/m^3
