A 75 g bullet is fired from a rifle having a barrel 0.650 m long. Assuming the origin is placed where the bullet begins to move,

kolbaska11 [484]

Answer:

7557.875 J

Explanation:

Assumimg we need to find work done by the bullet on the gas

The work is found by integrating force over distance

W= $W=\int_{x_i}^{x_f}F.ds$

For the force in this problem we have

$W=\int_{0}^{0.65}14000 + 10000x - 21000x^2.ds$

= $[14000x+10000x^2-21000x^3]_{0}^{0.65}$

=7557.875 J

A 0.290 cm diameter plastic sphere, used in a static electricity demonstration, has a uniformly distributed 30.0 pC charge on it

mojhsa [17]

Answer:

Therefore,

The potential (in V) near its surface is 186.13 Volt.

Explanation:

Given:

Diameter of sphere,

d= 0.29 cm

$radius=\dfrac{d}{2}=\dfrac{0.29}{2}=0.145\ cm$

$r = 0.145\ cm = 0.145\times 10^{-2}\ m$

Charge ,

$Q = 30.0\ pC=30\times 10^{-12}$

To Find:

Electric potential , V = ?

Solution:

Electric Potential at point surface is given as,

$V=\dfrac{1}{4\pi\epsilon_{0}}\times \dfrac{Q}{r}$

Where,

V= Electric potential,

ε0 = permeability free space = 8.85 × 10–12 F/m

Q = Charge

r = Radius

Substituting the values we get

$V=\dfrac{1}{4\times 3.14\times 8.85\times 10^{-12}}\times \dfrac{30\times 10^{-12}}{0.145\times 10^{-2}}$

$V=\dfrac{30}{16.117\times 10^{-2}}=186.13\ Volt$

Therefore,

The potential (in V) near its surface is 186.13 Volt.

List possible causes of fever and explain the benefits of fever

olga2289 [7]

Answer:

Fever or elevated body temperature might be caused by:

A virus.

A bacterial infection.

Heat exhaustion.

Certain inflammatory conditions such as rheumatoid arthritis — inflammation of the lining of your joints (synovium)

A malignant tumor.

Many illness-causing microbes do best at the body's normal temperature. A fever raises the temperature beyond which certain microbes need to reproduce. A fever also kicks your child's immune system into high gear, spurring the rapid production of bug-clobbering white blood cells.

Radio telescopes measure the galaxy’s distribution of

dmitriy555 [2]

Radio Telescopes measures the galaxy's distribution of stars, galaxies, blackholes and other astronomical objects. It is used to study naturally -occuring radio light which is emitted by these astronomical bodies. Radio observatories are located far away from major cities to avoid electromagnetic interference from radio, televisions and radar.
