There are three major kinds of power supplies: unregulated (also called brute force), linear regulated, and switching. The fourth type of power supply circuit called the ripple-regulated, is a hybrid between the “brute force” and “switching” designs, and merits a subsection to itself.
Answer:
112.23 m
Explanation:
Displacement is the final position minus the initial position.
Δx = x − x₀
Δx = 100.1 m − (-12.13 m)
Δx = 112.23 m
Answer:
a) 0.063m
b) 2.72°
c) 3151 fringes
d) 1.87*10^-6m
Explanation:
a) To find the screen distance you use the following formula:
D: screen distance
d: distance between slits
m: order of the fringes
λ: wavelength
By replacing the values of the parameters you obtain:
b) The condition for dark fringes is given by:
for the first dark fringe the angle is:
c) the visible number of fringes is given by:
d) the wavelength of a laser in which its first order fringe coincides with the third one of the CuAr laser is:
Answer:
The horizontal speed with which the slingshot hits the balloon is approximately 57.358 m/s
Explanation:
The given parameters of the slingshot motion are;
The initial velocity of the slingshot, v = 100 m/s
The angle (to the horizontal) at which the slingshot is fired makes, θ = 55°
The path of the slingshot which hits the stationary balloon at the top of its flight = Parabolic trajectory
The horizontal component of the velocity = vₓ = v·cos(θ) = Constant
vₓ = 100 × cos(55°) ≈ 57.358
The horizontal speed with which the slingshot hits the balloon = vₓ ≈ 57.358 m/s.
The tilt of the earth on its axis causes the seasons.
