Answer:
L = 5.68 10¹⁷ m
Explanation:
The resolution of the telescope is given by diffraction
a sin θ = m λ
Where a is the separation of the linear slits, λ the wavelength, m an integer that determines the order of diffraction
In this case, suppose that the premieres meet Rayleigh's criteria, which establishes that the central maximum of the diffraction of an object coincides with the first minimum of diffraction of the second object. In this case m = 1
sin θ = λ / a
In the case of circular openings, polar coordinates must be used, so the equation is
sin θ = 1.22 λ / D
Where D is the diameter of the lens or tightness. Since the distances are very large and the small angles we can approximate the sine to the radian angle value
θ = 1.22 λ / D
Let's use trigonometry to find the angle. We have the separation of the premieres y = 3.7 10¹¹ m and
tan θ = y / L
θ = y / L
Let's replace
y / L = 1.22 λ / D
L = y D / 1.22 λ
calculate
L = 3.7 10¹¹ 1.03 / (1.22 550 10⁻⁹)
L = 5.68 10¹⁷ m
Answer:
76 minutes.
Explanation:
There are 60 minutes in an hour + 16 minutes= 76 minutes.
2. 0 mc charge in an external field of 20n/c, north (direction) will experience a force of 0.4 newtons, the direction of the force is north
Force in an electric field = charge * electric field
given
charge = 2* 
C
electric field = 20 N/C
Force in an electric field = 2* * 20
= 0.04 N
since , external field is in north direction then the force must be in north direction because the direction of an electric field at a point is the same as the direction of the electric force acting on a positive test charge
hence, 2. 0 mc charge in an external field of 20n/c, north (direction) will experience a force of 0.4 newtons, the direction of the force is north

Acceleration = (change in speed) / (time for the change)
-- during the first second, the object increases its speed to
(5 m/s²) · (1 s) = 5 m/s .
-- During the next 2 seconds, the object increases its speed by
(2 m/s²) · ( s) = 4 m/s
So at the end of the whole 3 seconds, its speed is (5 m/s) + (4 m/s) = 9 m/s
-- Over the whole time, its speed has changed from zero to 9 m/s.
Acceleration = (change in speed) / (time for the change)
Acceleration = (9 m/s) / (3 sec)
<em>Acceleration = 3 m/s²</em>
