Answer:
Explanation:
If a be grating element
a = 1 x 10⁻² / 11000
= .0909 x 10⁻⁵
= 909 x 10⁻⁹ m
for first order maxima , the condition is
a sinθ = λ where λ is wavelength
909 x 10⁻⁹ sin 49.67 = λ₁
λ₁ = 692.95 nm .
λ₂ = 909 x 10⁻⁹ sin 50.65
= 702.91 nm
λ₃ = 909 x 10⁻⁹ sin 52.06
= 716.88 nm
λ₄ = 909 x 10⁻⁹ sin 52.89
= 724.90 nm
692.95 nm , 702.91 nm , 716.88 nm , 724.90 nm .
Answer:
0.001225 kg/L × 720 000 000 L = 882000 kg
Explanation:
Given:
The equation to solve is given as:
0.001225 kg/L × 720 000 000 L = ?
Let us write each term of the product in terms of power of 10.
As 0.001225 has 6 digits after the decimal place, therefore, we use the exponent 6 for 10 and the sign is negative. This gives,

Now, for 720000000 L there are 6 zeros after 720. So, we use exponent 6 but with a positive sign. This gives,

Now, finding the product, we get:

Therefore, the product is equal to:
0.001225 kg/L × 720 000 000 L = 882000 kg
Answer:
No
Explanation:
Some objects gain momentum.
To determine the mass plated, we use Faraday's Law of Electrolysis. We calculate as follows:
q = It
q = 8.70 (33.5) (60)
q = 17487 C
mass = 17487 C ( 1 mol e- / 96500 C) ( 1 mol / 2 mol e-) (107.9 g /mol)
mass = 9.78 g
Hope this helps.
Explanation:
The given data is as follows.
= 120 V,
= 6.50 V
= 400,
= ?
Formula to calculate the number of turns in secondary coil are as follows.

Putting the given values into the above formula as follows.


= 21.66
= 22 (approx)
Thus, we can conclude that number of turns in the secondary coil are 22.
