It’s been a long time since I last learned this but I think it’s C.
(30x4x100)/4x90 = 100/3

Phoenix [80]
The PE for this question will be 588,000 because we take the mass (2,000 kg), multiply it by 9.8 which is Gravitational Acceleration and then multiply that by the height (30 meters)

Find the voltage across the 15 Q resistor.<br> [?] V<br><br> No links please
Margaret [11]

Answer:

Explanation:

same idea as before Liam,  first, find the parallel resistance in 35 || 20

(35*20)  / (35+20)  = 700 / 55  = 12.727272 ohms

now add the  12.727272 + 15 = 27.727272 ohms total resistance

V = IR

10 = I *    27.727272

10 / 27.727272 = I

0.360655 = I

V = IR  (again, but across the 15 ohm resistor)

V =     0.360655 * 15      

V = 5.4098

The absolute pressure, in kilopascals, a depth 10m below sea level is most nearly?
saul85 [17]

Answer:

option A

Explanation:

given,

depth of the sea level = 10 m

g = 10 m/s²

Pressure underwater = ?

we know,

P = ρ g h

where ρ is the density of water which is equal to 1000 kg/m³

h is the depth of sea level

P = ρ g h

P = 1000 x 10 x 10

P = 100000 Pa

P = 100 kPa

Hence, the correct answer is option A
