Vector subtraction ( A-B) is a special case of vector addition,since A-B = A + (-B). Suppose that the cases of vectors addition
kotykmax [81]

Answer:

Check Explanation

Explanation:

The magnitude of the resultant for the vector subtraction will definitely be different from the magnitude of the resultant for the vector addition.

The attached image shows clearly that there will always be a difference between the two resultants. The magnitude of one will always be bigger than the other.

From the attached image,

- F₂ is a force vector in the direct opposite direction to F₂ (albeit, they have the same magnitude).

R₁ = F₁ + F₂

R₂ = F₁ - F₂

If the angle between the force vectors is an acute angle, the magnitude of the resultant for the vector subtraction will be greater than that of the resultant of vector addition.

A proton is located at a distance of 0.333 m from a point charge of 8.25 pC. The repulsive electric force moves the proton until
Andrej [43]

The wavelength of the proton is 9.8 \times 10^{-12} m

solution:

\Delta PE= PE_1-PE_2\\\Delta PE= k\times q\times e( \frac{1}{r_1}- \frac{1}{r_2} )\\\Delta PE = 9 \times10^9\times 8.25 \times 10^-^61.6 \times 10^{-19} \times(\frac 1{0.333} -\frac 1{1.64})\\\Delta PE = 2.01 \times 10^{-14 }J.

also energy E = \frac{h \times c}{\lambda}

\lambda = \frac{h \times c}{E} \\\lambda = \frac {6.626 \times10^{-34} \times 3 \times10^8}{2.01 \times10^{-14}} =9.8 \times 10^{-12} m

<h3>What is wavelength?</h3>
  • The distance over which a periodic wave's shape repeats is known as the wavelength in physics.
  • It is a property of both traveling waves and standing waves as well as other spatial wave patterns. It is the distance between two successive corresponding locations of the same phase on the wave, such as two nearby crests, troughs, or zero crossings.
  • The spatial frequency is the reciprocal of the wavelength. The Greek letter lambda is frequently used to represent wavelength.
  • The term wavelength is also occasionally used to refer to modulated waves, their sinusoidal envelopes, or waves created by the interference of several sinusoids.

Confining pressure is where ________. Confining pressure is where ________. pressure is parallel to the bedding planes pressure
Brrunno [24]

Answer:

d) Forces are applied equally in all directions

Explanation:

Confining pressures are pressures imposed on a layer of soil by the weights of the layers on top of it. Confining pressures occur as a result of equal transmission of forces between the layers of a material (usually rock and soil).

It can also be described as an equal, all-sided pressure produced by overlying rocks in the crust of the earth.  As the confining pressure increases, the critical elastic energy of the layers of the material transforms from linear to exponential.
