A volcanic eruption launches two rocks of different masses into the air. The first rock had a mass of 10 kilograms while the sec
Artist 52 [7]

Answer:

C. The amount of force applied to rock one was half the amount of force applied to rock two during the eruption.

Explanation:

A force is an agent which changes the state of an object well applied to it. Second Newton's law of motion state's that;

F = ma

where F is the force, m is the mass of the object and a is the acceleration of the object.

In the given question,

Mass of first rock = 10 kilograms

Mass of the second rock = 20 kilograms

Acceleration of the two rocks = 600 m/s^{2}

Thus,

Force on the first rock = ma

                                    = 10 x 600

                                    = 6000 N

Force on the second rock = 20 x 600

                                   = 12000 N

Therefore, it can be observed that the amount of force applied to rock one was half the amount of force applied to rock two during the eruption.

Samantha's teacher asks her to describe motion in one dimension. This type of motion is always
Whitepunk [10]

A motion in one dimension is a type of motion that is always along a straight line and has a constant acceleration.

Motion refers to a change in the location (position) of an object or physical body with respect to a reference point, especially due to the action of an external force.

In Science, the motion of an object or physical body is described in terms of the following parameters:

  • Speed
  • Force
  • Acceleration
  • Distance
  • Time

Furthermore, there are three (3) forms of motion based on dimension and these include:

1. Motion in one dimension

2. Motion in two dimension

3. Motion in three dimension

A motion in one dimension (one-dimensional motion) is also referred to as rectilinear or linear motion. Also, it is always along a straight line in any direction and characterized by constant acceleration.

A small metal bead, labeled A, has a charge of 26 nC . It is touched to metal bead B, initially neutral, so that the two beads s
adell [148]

Answer:

q_A=25.953\ \rm nC

q_B=0.047\ \rm nC

Explanation:

Given:

  • Total initial charge on bead A=26 nC
  • The distance between them=5 cm
  • Magnitude o the force between them =4.4\times10^{-4}

Using coulombs law the force between two charged particle is \dfrac{q_Aq_B}{4\pi \epsilon_0 r^2}

where r is the radial distance between them

According to question we have

4.4\times10^{-4}=\dfrac{q_Aq_B\times9\times10^9}{0.05^2}\\\\4.4\times10^{-4}=\dfrac{q_A(q_A-26\times10^{-9})\times9\times10^9}{0.05^2}\\q_A=25.953\ \rm nC\\q_B=0.047\ \rm nC

Hence the charge on two metal beads is calculated.
