A Ping-Pong ball has a mass of 2.3 g and a terminal speed of 9.2 m/s. The drag force is of the form bv2 What is the value of b?
Bingel [31]
Drag force is a force that resist the motion of a certain body through a fluid like air or water. This can be calculated through the equation,
                                    D = 0.5Cρv²
where D is drag, C is the drag coefficient, ρ is the density and v is the velocity. The value therefore of b in the item above is,
                                        b = 0.5Cρ

One can lessen the force that acts on an object<br> True or false
Artemon [7]

Answer:

True

Explanation:

It is possible to reduce/lessen the force that is acting on an object. For example, if you were pushing on a box and wanted to push less on the box, that would be possible.

Answer:

A.this belief is especially strong in South Korea is Buddhism.

B.this belief forms a majority in many northwestern Chinese

communities is Buddhism.

Buddhism is a tradition that focuses on personal spiritual development. Buddhists strive for a deep insight into the true nature of life and do not worship gods or deities.

C. The majority of Japanese follow this belief is Shinto.

Shinto  is the traditional religion of Japan that focuses on ritual practices to be carried out diligently to establish a connection between present-day Japan and its ancient past.

D. most East Asians adhere the to this belief is Islam.

Islam is a popular religion teaching that there is only one God (Arabic: Allah), and that Muhammad is the messenger of God. It is the world's second-largest religion with over 1.8 billion followers or 24% of the world's population, most commonly known as Muslims.

Birds resting on high-voltage power lines are a common sight. the copper wire on which a bird stands is 1.28 cm in diameter and
nekit [7.7K]

Answer:

8\cdot 10^{-4} V

Explanation:

First of all, let's find the cross-sectional area of the copper wire. The radius of the wire half the diameter:

r=\frac{d}{2}=\frac{1.28 cm}{2}=0.64 cm=6.4\cdot 10^{-3} m

So the area is

A=\pi r^2 = \pi (6.4\cdot 10^{-3} m)^2=1.29\cdot 10^{-4} m^2

Now we can calculate the resistance of the piece of copper wire between the bird's feet, with the formula:

R=\rho \frac{L}{A}

where

\rho=1.68\cdot 10^{-8} \Omega m is the resistivity of copper

L=4.12 cm=4.12 \cdot 10^{-2} m is the length of the piece of wire

A=1.29\cdot 10^{-4} m^2 is the cross-sectional area

Substituting, we find

R=(1.68\cdot 10^{-8} m^2)\frac{4.12\cdot 10^{-2} m}{1.29\cdot 10^{-4} m^2}=5.4\cdot 10^{-6} \Omega

And since we know the current in the wire, I=149 A, we can now find the potential difference across the body of the bird, by using Ohm's law:

V=IR=(149 A)(5.4\cdot 10^{-6} \Omega)=8\cdot 10^{-4} V
