If the primary coil of a transformer has 200 turns and is supplied with 120 v ac power, how many turns must the secondary coil h

ave to provide 12 v ac power?

The ratio of the turns to the voltage should be equal
i.e: 200/120 = t/12
so the secondary coil should have 20 turns

A fluid has a density of 921 kg/m^3. at a depth of 1.22 m, the fluid pressure is 122,000 Pa. what is the pressure at the top of

Igoryamba

Answer:

111,000 Pa

Explanation:

P = Patm + ρgh

122,000 Pa = Patm + (921 kg/m³) (9.8 m/s²) (1.22 m)

Patm = 111,000 Pa

b. The stream of water flowing through a hole at depth h = 10 cm in a tank holding water to height H = 40 cm. . 3 At what distan

topjm [15]

Answer:

34.64 cm

Explanation:

Given that:

The depth of the hole h = 10 cm

height of the water holding in the tank H = 40 cm

For a stream of flowing water, the distance (x) at which the stream strikes the floor can be computed by using the formula;

$x = 2 \sqrt{h(H-h)}$

$x = 2 \sqrt{10(40-10)}$

$x = 2 \sqrt{10(30)}$

$x = 2 \sqrt{300}$

$x = 2 \times 17.32$

x = 34.64 cm
