1. Lance starts the cycling marathon with a velocity of 6.2 m/s. Lance increases
his velocity to 9.7 m/s in 8 seconds. What is Lance's acceleration during this time?

Answers

Answer 1
0.4375 m/s^2

Acceleration is change in velocity over time

Change in velocity (Vf-Vi) 9.7m/s - 6.2m/s = 3.5 m/s

Time is 8 seconds

Acceleration = 3.5m/s / 8s = 0.4375 m/s^2

A 2.75 kg block is pulled across a flat, frictionless floor with a 5.11 N force directed 53.8° above horizontal. What is the total force acting on the block? (total force = N)

Answers

Answer:

F = 3.01 N

Explanation:

Given that,

Mass of a block, m = 2.75 kg

Force applied to the block, F = 5.11 N

It is directed 53.8° above horizontal.

We need to find the total force acting on the block. The force acting on it is given by :

[tex]F=F\cos\theta\\\\F=5.11\times \cos53.8\\F=3.01\ N[/tex]

So, 3.01 N of force is acting on the block.

3.01 works as the right answer

Calculate acceleration of a turtle going from 0.3 m/s to 0.7 m/s in 30 seconds.

Answers

Answer:

acceleration = 0.013 m/s²

Explanation:

formula for acceleration is

a = (v-u) / t

a= (0.7-0.3) / 30

= 0.013

The acceleration of a turtle going from 0.3 m/s to 0.7 m/s in 30 seconds is 0.0133m/s²

Acceleration is defined as the change in velocity of a body with respect to time. Mathematically:

[tex]a=\frac{v-u}{t}[/tex]

v is the final speed = 0.7m/s

u is the initial speed = 0.3m/s

t is the time taken = 30seconds

Substitute the given values into the formula:

[tex]a=\frac{0.7-0.3}{30}\\a=\frac{0.4}{30}\\a = 0.0133m/s^2[/tex]

Hence the acceleration of a turtle going from 0.3 m/s to 0.7 m/s in 30 seconds is 0.0133m/s²

Explain the challenges in developing an accurate rating system for earthquakes. What kinds of variables are there?

Answers

Answer:

In turn, the main factors affecting earthquake shaking intensity are earthquake depth, proximity to the fault, the underlying soil, and building characteristics—particularly height. Let's take a look at the latter two (soil and buildings) and how they interact.

The challenge in developing an accurate rating system for earthquakes is due to complicated relationship between variables such as magnitude and intensity of earthquake.

Earthquakes are associated with magnitude and intensity.

The challenge in developing an accurate rating system for earthquake is due to complicated relationship and dependency between the magnitude and intensity of the earthquake.

Intensity of earthquake is the observed effects resulting from the earthquake such as; shaking of buildings, people etc. This intensity of the earthquake depends on the location of the observer with respect to earthquake epicenter.The magnitude of the earthquake relates to the amount of energy released during the earthquake.

Thus, the challenge in developing an accurate rating system for earthquakes is due to complicated relationship between variables such as magnitude and intensity of earthquake.

what is the magnitude of the eletrostatic force on an electron by another electron when they are 0.10 meter apart?

Answers

Answer:

[tex]F=2.30\times 10^{-26}\ N[/tex]

Explanation:

The distance between two electrons, d = 0.10 m

We need to find the magnitude of the electrostatic force on an electron by another electron.

The electrostatic force between two charges is given by :

[tex]F=k\dfrac{q_1q_2}{d^2}[/tex]

Substitute all the values,

[tex]F=\dfrac{9\times 10^9\times (1.6\times 10^{-19})^2}{(0.1)^2}\\\\F=2.30\times 10^{-26}\ N[/tex]

So, the magnitude of the electrostatic force between two electrons is [tex]2.30\times 10^{-26}\ N[/tex].

It is a force imposed by one charge on another as a result of the field. The magnitude of the electrostatic force will be 2.30×10⁻²⁶N.

What is the electrostatic force?

It is a force imposed by one charge on another as a result of the field. The electrostatic force produced by one line charge on another line charge is inverse of the square of the radius.

The electrostatic force is determined by the charge potency of each charge as well as the separation distance between them.

The given data in the problem is;

q=q₁=q₂ is the electric charge = 1.6×10⁻¹⁹C

r is the distance between the two charge=0.10 m

The formula for the electrostatic force is given by;

[tex]\rm F=\frac{ Kq_1q_2}{r^2} \\\\ \rm F=\frac{ 9\times 10^9 \times(1.6\times 10^{-19})^2}{(0.1)^2}\\\\ \rm F =2.30 \times 10^{-26} \ N[/tex]

Hence the magnitude of the electrostatic force will be 2.30×10⁻²⁶N.
