Work out the following a) Find β = v/c for a person walking at 3 mile/hr and a truck moving at 65 mile/hr. (b) Find γ-1, where γ

balu736 [363]

Explanation:

It is given that,

Speed of the person, v = 3 mile/hr = 1.34 m/s

Speed of the truck, v' = 65 mile/hr = 29.05 m/s

(a) Since, $\beta =\dfrac{v}{c}$

For the person, $\beta =\dfrac{1.34}{3\times 10^8}=4.47\times 10^{-9}$

For the truck, $\beta =\dfrac{29.05}{3\times 10^8}=9.68\times 10^{-8}$

(b) The relativistic factor is given by :

$\gamma=\dfrac{1}{\sqrt{1-\beta^2}}$

For very small velocity, $\beta$

$\gamma=(1-\beta ^2)^{-1/2}\approx 1+\dfrac{1}{2}\beta ^2$

$\gamma-1=\dfrac{\beta^2}{2}$

For the person :

$\gamma-1=\dfrac{(4.47\times 10^{-9})^2}{2}=9.99\times 10^{-18}$

For the person :

$\gamma-1=\dfrac{(9.68\times 10^{-8})^2}{2}=4.68\times 10^{-15}$

Hence, this is the required solution.

The athlete at point A runs 150m east, then 70m west and then 100m east. Determine the resultant displacement of the athlete rel

polet [3.4K]

Answer:

180m to the east

Explanation:

Displacement is the distance traveled in a specific direction. It is a vector quantity with both magnitude and direction. Therefore, the start and finish position is very paramount.

point A runs 150m east,

70m west

100m east

150m

--------------------------------------------------------→

70m

←---------------------

100m

-----------------------------------→

The displacement of the athlete = 150 - 80 + 100 = 180m to the east

What unit is defined to express a quantity as a result of a 1 m s2 acceleration of a 1 kg object?

Dafna11 [192]

The definition of a Newton (unit) is an expression of a quantity as a result of a $1 m/s^{2}$ object acceleration.

<h3>What is the SI newton unit?</h3>

The Standard International (SI) unit of force is the newton. The letter N is frequently used to shorten the phrase "newton" in physics and engineering documents. In the absence of any other forces, one newton is the force necessary to accelerate a mass of one kilogram at a pace of one meter per second squared.

<h3>What are the equivalents of a newton in terms of mass and acceleration?</h3>

One Newton is the amount of force required to accelerate one kilogram of mass one squared meter per second.

<h3>Is the newton a measure of force?</h3>

The newton, abbreviated N, is the SI unit of force. Base units that are pertinent to force are: The symbol for the length unit of a metre is m. the kilogram (kg), a unit of mass.
