The correct answer for above statement is:

Walking across a carpet can build up a charge due to friction.

Explanation:

As you walk, some electrons are peeled away and a potential difference can grow up. The covered floor is a nonconductor (or can be the surface that is stripping away the electrons) so the charge can’t evanesce from your body till you encounter a metal doorknob or something grounded.

Para que ángulo el alcance es igual a la altura máxima en un lanzamiento de proyectil ideal sobre un plano horizontal. Translati
Gemiola [76]

Answer:

<h2>76°</h2>

Explanation:

In projectile,

Maximum height = \frac{u^{2}sin^{2} \theta  }{2g} and range = \frac{u^{2}sin2\theta }{g}

u = velocity of the body

\theta = angle of launch

g = acceleration due to gravity

If the range equals the maximum height in an ideal projectile launch on a horizontal plane, this means;

\frac{u^{2}sin^{2} \theta  }{2g} = \frac{u^{2}sin2\theta  }{g}

since sin2\theta = 2sin\theta cos\theta

\frac{u^{2}sin^{2} \theta  }{2g} = \frac{u^{2}2sin\theta cos\theta }{g}\\\frac{sin\theta}{2} =2cos\theta \\sin\theta = 4cos\theta\\\frac{sin\theta}{cos\theta}  = 4\\tan\theta = 4\\\theta = tan^{-1} \\4\theta = 75.9^{0}

The angle at which the range equals the maximum height in an ideal projectile launch on a horizontal plane is approximately 76°

Describe how humans’ actions and natural processes have modified coastal regions in Louisiana and other locations
il63 [147K]
Coastal erosion has depleted a large portion of South Louisiana's wetlands along the coastline in swamps and marshes mainly due to storm surges. But other factors also contributed to this erosion. Canals and waterways dug through the marshes and swamps for the oil industry is one factor. Man-made levees erected to provide protection to residents living adjacent to the river is another major cause. Large scale logging especially in the early 1900's also damaged the wetlands.

Different betweenof mass and weight​
Eduardwww [97]

Answer:

The differences are:

Mass:

1) It is the total amount of matter contained in a body.

2) It's SI unit is kilogram (kg).

3) It's measured by using beam balance

Weight:

1) It is the force which pulls an object towards the center of the earth.

2) It's SI unit is newton(n).

3) It's measured by using spring balance.

stich3 [128]

Answer:

Option B

Explanation:

The correct answer is Option B.

Before Moseley's discovery in 1913, In Mendeleev's periodic table the elements rearranged with increasing atomic mass.

Mendeleev was not able to locate hydrogen atom and late isotopes found violate Mendeleev table. The biggest drawback was that the atomic mass was not regular when moving one element to another.

But Moseley's arranged element in the periodic table with increasing atomic number.
