C.) Wristwatch uses DC current to operate..
Answer:
λ = 8.716 mm
Explanation:
Given:
- d = 10 cm
- Q >= 5 degrees
Find:
- Find the shortest wavelength of light for which this apparatus is useful
Solution:
- The formula that relates the split difference and angle of separation between successive fringes is given by:
d*sin(Q) = n*λ
Where,
λ: wavelength
d: split separation
Q: angle of separation between successive fringes
m: order number.
- Since this apparatus only shows the first order light so m =1
- the shortest possible wavelength corresponds to:
d*sin(Q) = λ
λ = 0.1*sin(5)
λ = 8.716 mm
Answer:
When the electrical current passes through the conductors, the polarity is changed, and the diaphragm interacts with the permanent magnets, vibrating and creating sound.

Explanation:
The main purpose of wheel and axle to Migrating the particles as well as elevate the objects and the people.The wheel is the rounded disk or it may be the the rectangular outer part and the axle is the curved cylinder.
- The axle is operating via the center square So they are connected to the various object.
- The wheel and the axle applications involve trying to lifting the large loads as well as pushing the things rapidly.
