Answer:
0.541 nm
Explanation:
The condition for maxima is,
Here, m=0,1,2,.....
And d is the slit separation, m is the order of maxima, 
is the wavelength.
Given that, the 17.3 eV electron posses a wavelength of
And the order of maxima is 
.
And the angle at which first order maxima occur is, 
.
Put these values in maxima condition while solving for d.
Therefore, the slit separation is 0.541 nm.

Answer:
Speed acquired (Final velocity) = 12 m/s
Distance travelled = 720 meter
Explanation:
Given:
Uniform acceleration = 0.1 m/s²
Initial velocity = 0 m/s
Time taken = 2 minutes = 2 x 60 = 120 second
Find:
(a) Speed acquired (Final velocity)
(b) Distance travelled
Computation:
v = u + at
v = 0 + 0.1(120)
Speed acquired (Final velocity) = 12 m/s
Distance travelled = ut + (1/2)(a)(t²)
Distance travelled = (0)(120) + (1/2)(0.1)(120²)
Distance travelled = (1/2)(0.1)(14400)
Distance travelled = 720 meter
Answer:
C. matching coastlines
Explanation:
The theory of continental drift was originally proposed in 1912 by German meteorologist and geophysicist Alfred Wegener (1880-1930), who formulated it based, among other things, on how they seemed to fit the shapes of the continents on each side of the Atlantic Ocean, such as Africa and South America. This had previously been speculated by some mapmakers.
