Answer:
B
Explanation:
Gravity is an invisible force, and so is magnetism and electricity. Friction involves the rubbing of things together to create energy.
no, work is = force * distance or displacement
Answer:
it increases by a factor 1.07
Explanation:
The peak wavelength of an object is given by Wien's displacement law:
(1)
where
b is the Wien's displacement constant
T is the temperature (in Kelvins) of the object
given the relationship between frequency and wavelength of an electromagnetic wave:

where c is the speed of light, we can rewrite (1) as

So the peak frequency is directly proportional to the temperature in Kelvin.
In this problem, the temperature of the object changes from

to

so the peak frequency changes by a factor

Answer:
True
Explanation:
Charts are the most accurate way to measure most things. For example, a chart can help you understand how the population of the world has changed since 1998.
