Answer:

Explanation:

lthough the earliest examples of mummification were accidental, with bodies being preserved because of very dry, desert conditions, it soon became religiously important in ancient Egypt and was done deliberately. Ancient Egyptians believed that a happy afterlife depended in part on careful mummification. The word mummification is formed with the suffix -fication, "a making or causing," and mummy, from the Arabic mumiyah, "embalmed body," from the Persian root mum, "wax."

A 1000 kg car experiences a net force of 9500 N while slowing down from 30 m/s to 16 m/s. How far does it travel while slowing d

rjkz [21]

Answer:

33.89 m

Explanation:

We must first obtain the acceleration of the car from;

F=ma

Where

F= force= 9500 N

m= mass of the car= 1000kg

a= acceleration

a= F/m= 9500/1000

a= 9.5 m/s^2

From;

V^2=u^2 + 2as

Where;

V= final velocity

u= initial velocity

s= distance covered

a= acceleration

s= v^2 -u^2/2a

s= (30)^2 -(16)^2/2×9.5

s= 900 - 256/19

s= 644/19

s= 33.89 m

Describe what happens, at a microscopic level, when an object is charged by rubbing. For instance, what happens when a plastic p

olga_2 [115]

Answer:

Explanation:

The static charges are generated due to excess or deficiency of electrons, because these are the smallest quanta of charge available at the molecular level which can get transferred with minimal energy requirement.

These charges are usually generated by friction between the two surfaces leading to the transfer of electron from one to another.

When a plastic pipe is rubbed with a cloth then due to friction the surface of the cloth loses electron which gets stuck at the surface of the pipe making it negatively charged.

An artillery shell is fired at an angle to the horizontal. Its initial velocity has a vertical component of 150 meters per secon

Nana76 [90]

Answer:

300.16m/s

Explanation:

An artillery shell is fired at an angle to the horizontal. Its initial velocity has a vertical component of 150 meters per second and a horizontal component of 260 meters per second. What is the magnitude of the initial velocity of the shell?

note velocity is the change in displacement to time

to find the magnitude of the initial speed ,

we will find the square of the vertical component plus the square of the horizontal component. then we look for the square root

U= $\sqrt{Ux^2+Uy^2}$

U= $\sqrt{260^2+150^2}$

U=90,100^2

U=300.16m/s

means that it covers 300.16m in 1 seconds

In Europe, gas cost approximately €0.98 per liter. How many dollars($) per gallon is this? using a factor method

bixtya [17]

Answer:

€0.98 per liter = 4.377 doller per gallon

Explanation:

It is given that, In Europe, gas cost approximately €0.98 per liter. We need to convert it into dollars($) per gallon.

We know that, 1 euro = 1.18 United States Dollar

1 litre = 0.264172 US gallon

Cost of gas in Europe is €0.98 per liter.

$0.98\ \text{euro/ liter}=\dfrac{0.98\times 1.18\ \text{doller}}{0.264172\ \text{gallon}}\\\\=4.377\ \text{doller/gallon}$
