Answer:
D = 0.2374 m
Explanation:
let D be the diameter of the image of mars, f be the focal length of the telescope mirror and β be the spatial resolution.
β = 6794×10^3/(5.58×10^7) = 0.1217562724
then:
The diameter of the telescope mirror is given by:
D = f×β
= (1.95)×(0.1217562724)
= 0.2374 m
Therefore, the diameter of the image of mars is 0.2374 m.
Answer :
(-3.7 meter/second) - (13.9 meter/second) = -17.6 meter/second
(21.4 second) - (72 second) = -50.6 second
Explanation :
(1) As we are given the expression :
(-3.7 meter/second) - (13.9 meter/second)
Now we have to evaluate this expression, we get:
⇒ -17.6 meter/second
(2) As we are given the expression :
(21.4 second) - (72 second)
Now we have to evaluate this expression, we get:
⇒ -50.6 second
The atomic number is the number of protons in the nucleus of an atom. The number of protons define the identity of an element (i.e., an element with 6 protons is a carbon
