Reil [10]

1200

Explanation:

F = m x (v / t)

v / t = F / m

v = (F / m) / t

v = (600 / 5) / 0.1

v = 120 / 0.1

v = 1200 m / s

Give a different example of an inverse relationship (not using wavelength or frequency
ivanzaharov [21]

An example of an inverse relationship is the one between pressure and volume of an ideal gas

Explanation:

Boyle's law states that:

<em>"For a gas kept at a constant temperature, the pressure of the gas is inversely proportional to its volume" </em>

Mathematically,

pV=const.

where p is the pressure of the gas and V its volume.

The relationship can be written as

p\propto \frac{1}{V}

Therefore it is an example of inverse relationship, because:

  • As the volume increases, the pressure decreases
  • As the volume decreases, the pressure increases

A tetrahedron has an equilateral triangle base with 25.0-cm-long edges and three equilateral triangle sides. The base is paralle
KATRIN_1 [288]

Answer:

electric flux through the three side = 2.35 N m²/C

Explanation:

given,

equilateral triangle of base = 25 cm

electric field strength = 260 N/C

Area of triangle = \dfrac{\sqrt{3}}{4}a^2

                          =  \dfrac{\sqrt{3}}{4} 0.25^2

                          = 0.0271 m³

electric flux = E. A

                   = 260 × 0.0271

                   = 7.046 N m²/C

since, tetrahedron does not enclose any charge so, net flux through tetrahedron is zero.

electric flux through the three side = (electric flux through base)/3

                               = \dfrac{7.046}{3}

electric flux through the three side = 2.35 N m²/C
