What is the current of a 10 Ohm resistor attached to a 9 volt battery?

Gnom [1K]

I'm giving you a general formula , its called ohm law it states that electric current is proportional to voltage and inversely proportional to resistance

if V=voltage associated with the battery
R=resistance , I=current then
 $\boxed{V=I*R}$

A submarine is stranded on the bottom of the ocean with its hatch 21.0 m below the surface. calculate the force (in n) needed to

Tanzania [10]

Answer:

28,400 N

Explanation:

Let's start by calculating the pressure that acts on the upper surface of the hatch. It is given by the sum of the atmospheric pressure and the pressure due to the columb of water, which is given by Stevin's law:

$p_{top} = p_{atm} + \rho g h=1.013\cdot 10^5 Pa + (1000 kg/m^3)(9.8 m/s^2)(21.0 m)=3.071 \cdot 10^5 Pa$
