Answer:

D) C6H6

Explanation:

The strength of intermolecular forces between particles affects physical properties of substances such as boiling point, melting point, surface tension, and vapor pressure. Which substance has the highest melting point

A) C2H5O

B) C2H6

C) H2O

D) C6H6

C2H5O has a melting point of -114.1^{0}c

C2H6  has a melting point of -182.8^{0}c

H2O has a melting point of 0^{0}c

c6h6 has a melting point of 5^{0}c

benzene as the highest melting point

When molecules are tightly packed together, a substance has a higher melting point than a substance with molecules that do not pack well. ... Molecular mass also affects the melting point. , smaller molecules melt at lower temperatures than larger molecules.

melting point is the temperature at which a substance coexist as both solid and liquid without any noticeable change in temperature

A 60.0-kg mass person wishes to push a 120-kg mass box across a level floor. The coefficient of static friction between the pers
Aneli [31]

Answer:

μ = 0.350

Explanation:

For the person to able to move the box, the force exerted by the person on the box must equal the force exerted by the box:

F_{p} = F_{b}

In this case, force can be calculated as a product of mass (m) by the acceleration of gravity (g) and the coefficient of static friction (μ):

m_{p}*g*\mu_{p}=m_{b}*g*\mu_{b}\\m_{p}*\mu_{p}=m_{b}*\mu_{b}\\60*0.7=120*\mu_{b}\\\mu_{b}= 0.35

Therefore, for the person to be able to push the box horizontally, the coefficient of static friction between the box and the floor should not be higher than 0.350.

A fly has a mass of 1 gram at rest. how fast would it have to be traveling to have the mass of a large suv, which is about 3000
Zigmanuir [339]

We solve this using special relativity. Special relativity actually places the relativistic mass to be the rest mass factored by a constant "gamma". The gamma is equal to 1/sqrt (1 - (v/c)^2). <span>

We want a ratio of 3000000 to 1, or 3 million to 1. 

</span>

<span>Therefore:
3E6 = 1/sqrt (1 - (v/c)^2) 
1 - (v/c)^2 = (0.000000333)^2 
0.99999999999999 = (v/c)^2 
0.99999999999999 = v/c 
<span>v= 99.999999999999% of the speed of light ~ speed of light
<span>v = 3 x 10^8 m/s</span></span></span>
