If the three spoon touch nothing happens because they are all at room Temperature
1 Answer. 50% of the lunar surface is always illuminated by Sun
The number of orders that one can see the entire visible speed is 5 orders.
<h3>How to calculate the orders?</h3>
From the information given, it should be noted that the grating spacing will be:
d = (1.00 × 10^-4) / 250
d = 4000nm
Therefore, the number of times that are needed to complete the order will be the same as the number of orders which the long wavelength time will be visible. This will be:
= (4000 × sin 90°)/700
= 5.71
Therefore, the maximum orders will be 5.

Answer:
electromagnetic spectrum :)
Answer:
Explanation:
Magnetic field due to a long wire
B = ( μ₀ / 4π ) x 2 I / r ( I is current through the wire )
= (μ₀ Q t ) / ( 2 π r ) [ I = Q t ]
b ) Magnetic field will change through the length of the square shaped loop . So we shall have to take the help of integration to calculate the flux through the loop.
Flux Φ = ∫ B dA
=∫ ( μ₀ / 4π ) x 2 I / r dA
10⁻⁷ x 2 I ∫ a dr/r
2 x 10⁻⁷ x Qt x a [ ln (2.9+1.2) / 1.2 ]
4.6 x 10⁻⁷ x 2.9 x 10⁻² t ln 4.1 / 1.2
16.4 x 10⁻⁹ t
Φ( t ) = 16.4 x 10⁻⁹ t
Induced emf = dΦ( t ) / dt = 16.4 x 10⁻⁹ v
current
16.4 x 10⁻⁹ / 2.5
= 6.56 x 10⁻⁹
