Resultant force is 400-600=-200N.
-200=60a solve for a.
Underground, carbon can be stored in ____, which humans ___.
-----------------------------
coal, oil, fossil fuels ... humans burn for energy
Assuming it is on a horizontal surface:
friction = μR
R = 20g (g is gravity 9.81)
so Friction = 0.085 x 20g
Work done is force x distance
so Work done = 0.085 x 20g x 28
= 466.956 J
120 is your answer. 120 mL = 120 cm^3
Answer:
Explanation:
Given
Wavelength of radiation 
We know Energy of wave with wavelength
is given by

where h=Planck's constant
c=velocity of light
=wavelength of wave

Hence the energy of the wave with wavelength 784 m is
