Explanation:

An inertial frame of reference in classical physics and special relativity possesses the property that in this frame of reference a body with zero net force acting upon it does not accelerate; that is, such a body is at rest or moving at a constant velocity.[1] An inertial frame of reference can be defined in analytical terms as a frame of reference that describes time and space homogeneously, isotropically, and in a time-independent manner.[2] Conceptually, the physics of a system in an inertial frame have no causes external to the system.[3] An inertial frame of reference may also be called an inertial reference frame, inertial frame, Galilean reference frame, or inertial space.[4]

The voltage across a membrane forming a cell wall is 84.0 mV and the membrane is 9.40 nm thick. What is the electric field stren

Katarina [22]

Answer:

8.9*10^6 V/m

Explanation:

The expression for electric field strength E is given as

$E=\frac{V}{d}$

where V= voltage

d= distance of separation

Given data

$voltage= 84 mV= 84*10^-^3\\distance= 9.4*10^-^9$

substituting our given data into the electric field strength formula we have

$E= \frac{84*10^-^3}{ 9.4*10^-^9} \\\\E= \frac{84}{9.4} *10^-^3^-^(^-^9^)\\\\E= \frac{84}{9.4} *10^-^3^+^9\\\\E= \frac{84}{9.4} *10^6\\\\E=8.9*10^6 V/m$

Determine the work done by 2. 00 kg of water when it is all boiled to steam at 100 ∘c. Assume a constant pressure of 1. 00 atm.

neonofarm [45]

The work done by the water at the constant pressure is $-4.52 \times 10^6 \ J$ .

<h3>Heat required to boil the water</h3>

The heat required to boil the water is calculated as follows;

$Q = mL_v\\\\$

where;

$L_v$ is the heat of vaporization of water = 22.6 x 10⁵ J/kg
m is mass of water

$Q = 2 \times 22.6 \times 10^5\\\\Q = 4.52 \times 10^6 \ J$

<h3>Work done by the water</h3>

The work done by the water at the constant pressure is equal to the heat gained by the water.

$W = - \Delta H\\\\W = -4.52 \times 10^6 \ J$ .

Two charged particles attract each other with a force of magnitude F acting on each. If the charge of one is doubled and the dis

irakobra [83]

Answer:

F/2

Explanation:

In the first case, the two charges are Q1 and Q2 and the distance between them is r. K is the Coulomb's constant

Hence;

F= KQ1Q2/r^2 ------(1)

Where the charge on Q1 is doubled and the distance separating the charges is also doubled;

F= K2Q1 Q2/(2r)^2

F2= 2KQ1Q2/4r^2 ----(2)

F2= F/2

Comparing (1) and (2)

The magnitude of force acting on each of the two particles is;

F= F/2

Which type of energy is stored in a capacitor? electric potential energy chemical energy gravitational energy heat energy

Tom [10]

Energy stored in a capacitor is Electric Potential Energy. Capacitor is device used for storing energy. The work done to charge is a capacitor is stored in it in the form of Electrical potential energy. Electrical potential energy is defined as capacity to do work due to the position change. For example, we know fans have capacitor installed in it. When we turn off the fan, it continue moving using the electrical energy stored in the capacitor.
