The speed of a shallow water wave varies with

1 answer:

5 0

So we want to know how does the speed of a shallow water wave varies. If the wavelength is large enough in comparison to the depth of the water, meaning the wavelength is 20 times longer than the depth of water, the speed of a shallow water wave is the square root of gravity times water depth or: v=√(g*d), where v is speed of the wave, g=9.81 m/s^2 and d is water depth.

Answer:

0.005 meters

Explanation:

1 meter = 100 cm

Which means you get meter by this equation

$meter = cm \div 100$

Therefore the answer is

$0.5 \div 100 = 0.005$

A rechargeable battery is capable of delivering a current of 0.25 A for 1800 s at a potential difference of 1.5 V.

avanturin [10]

Answer:

a. q=450 c

b. E=675 J

Explanation:

Direct Current (DC)

It's the flow of electric charges in one direction driven by a constant voltage circuit. The intensity of the current flow is computed as

$\displaystyle I=\frac{q}{t}$

Where q is the constant flow of charge in time t

The energy of an element providing Voltage V, current I during a time t is

$E=V.I.t$

a. The charge can be computed by solving the first equation for q

$q=I.t=0.25\ A.\ 1800\ s=450\ c$

b. The energy transferred by the battery is

$E=(1.5).(0.25).(1800)=675\ J$

Consider an infinetly long hollow cylindrical wire. The wire has an outer diameter b and the clindrical hole at its center has d

Nadusha1986 [10]

Answer:

B = (μ₀*i/(2*π*x))*(x²-(a/2)²)/((b/2)²-(a/2)²)

Explanation:

Given

Outer diameter of the wire = b ⇒ R = b/2

Diameter of the clindrical hole at the center = a ⇒ r = a/2

The current that flows from left to right and is uniformly spread over the region between a and b = i

We apply Ampere's Law

Using the following formula for a/2 ≤ x ≤ b/2

B = (μ₀*i/(2*π*x))*(x²-(a/2)²)/((b/2)²-(a/2)²)
