Answer:

energy : the ability to cause change

work : is force x distance or when an object moves a distance due to a specific force (measured in units of newtons-meters)

potential energy  : is stored energy

kinetic energy : is energy in motion

mechanicle energy : the energy of motion such as a moving vechile

thermal energy : total kinetic energy in moving partsticles, like in boiling water (energy of heat)

chemical : energy stored in chemical bonds, like in plants

electromagnetic : waves with electric and magnetic properties , such as light

There is a maximum depth at which a diver can breathe through a snorkel tube because as the depth increases, so does the pressur
hammer [34]

Answer:59.78\times 10^3\ Pa

Explanation:

Given

Diver is at a depth of h=6.1\ m inside the water(\rho=10^3\ kg/m^3)

As we go down pressure increases due to the weight of liquid column above us

Pressure difference is given by P=\rho \times g \times h

Where \rho=density of liquid

h=depth

g=acceleration due to gravity

So external-internal pressure difference is

\Delta P=10^3\times 9.8\times 6.1

\Delta P=59.78\times 10^3\ Pa

The paper dielectric in a paper-and-foil capacitor is 0.0800 mm thick. Its dielectric constant is 2.50, and its dielectric stren
jeka94

Answer:

a) 0.723 m²

b) 2000V

Explanation:

Given that

Thickness of the capacitor, d = 0.08*10^-3 m

Dielectric constant of the capacitor, k = 2.5

Dielectric strength of the capacitor, E = 50*10^6

Capacitance of the capacitor, C = 0.2*10^-6

Permittivity of free space, E• = 8.85*10^-12

a)

The area, A is given by the formula

A = (C * d) / (k * E•)

A = (0.2*10^-6 * 0.08*10^-3) / (2.5 * 8.85*10^-12)

A = 1.6*10^-11 / 2.213*10^-11

A = 0.723 m²

b)

Potencial difference, V is given by the formula

V = E * d

V = 1/2 * 50*10^6 * 0.08*10^-3

V = 1/2 * 4000

V = 2000 V

Dovator [93]

λ = 3.125 m

λ = 2.83 m

<h3>Further explanation</h3>

Given

Frequency of radio : 96 MHz and 106 MHz

Required

The wavelength

Solution

Wavelength : from the crest to the crest of the next wave or the trough to the trough

Frequency (f): number of waves in one second

v = λ x f

λ = v : f

Input the value :

f = 96 MHz = 96 x 10⁶ Hz

λ = v : f

λ = 3 x 10⁸ :  96 x 10⁶

λ = 3.125 m

f = 106 MHz = 106 x 10⁶ Hz

λ = v : f

λ = 3 x 10⁸ :  106 x 10⁶

λ = 2.83 m
