What element has conductivity,shiney luster,magnitic <br> -science
nydimaria [60]

Answer:

The answer to this question is given below in this explanation section.

Explanation:

            "What element has conductivity,shiney luster,magnetic

-science"

silicon has a shiny luster,But it is brittle and conducts electricity poorly.Some metalloids change their characteristics when they react with different elements.Luster conductivity and malleability are physical properties can be observed be observed without attempting to change the identity of the substance.The term physical property is an observable characteristics of a substance. in this case the luster conductivity and malleability of metals are the properties, which can be observed  by our senses.It differs from chemical properties which can only be observed when the substance change its chemical identity.

Metal are solid at room temperature with the exception of mercury which is liquid at room temperature.Luster metal have the quality of reflection light from its surface and can be polished e.g gold,silver and copper.

What is the wavelength of 7.0-TeV protons? A) 550 nm B) 750 nm C) 5.4x10^-15 m D) 3.2x10^-18 m E) 1.8x10^-19 m
AnnZ [28]

Answer:

1.776 x 10^-19 m

Explanation:

Energy, E = 7 TeV

Let λ be the wavelength.

Energy = h c / λ

Where, h is the Planks,s constant and c be the velocity of light

h = 6.63 x 10-^-34 Js

c = 3 x 10^8 m/s

Convert TeV into J

1 TeV = 1.6 x 10^-7 J

So, E = 7 x 1.6 x 10^-7 = 11.2 x 10^-7 J

11.2 x 10^-7 = (6.63 x 10^-34 x 3 x 10^8) / λ

λ = 1.776 x 10^-19 m

An airplane flies with a constant speed of 780 miles per hour. How far can it travel in 4 hours?
BARSIC [14]

Answer:

3136

Explanation:

because you multiply 780 by 4 because if it has a constant speed meaning it will not change speed then you multiply it by 4 because it says in 4 hours ( I hope this helped)

A porter can carry 40 bricks of 10 N load of each. He can carry up to 75m in 40 sec, calculate his power.​
alexira [117]

Answer:

750W

Explanation:

40×10= 400N

work done= force × distance

=400 × 75

=30000 J

Power= work done/ time

= 30000 ÷ 40

= 750 W
