4 0

The bigger molecule has more interactions and hence the higher b.p. CH3CH2OCH2CH3 is a bigger molecule than CH4 and CH3CH3, so has more dispersion forces. It also has dipole-dipole forces due to the polarised C-O bonds. CH3OH and CH3CH2OH have hydrogen bonds due to the very electronegative O atom bonded to the H atom

Answer:

The correct answer t is ; $CH_4$ has a lower mass compared to $CH-3CH-3$ which leads to a higher boiling point.

Explanation:

Boiling point of alkanes increases with increase number of carbon atoms in the chain.

This is because along with increase in carbon atom molar mass of alkane also increases by which surface area of molecule increases which further results in increase in weak vander wall forces among the molecule. Due to this molecules associates strongly with each other and boils at high temperature

You are holding a finishing sander with your right hand. THe sander has a flywheel which spins counterclockwise as seen from beh

ryzh [129]

Answer:

c. turn downward

Explanation:

From the information given:

To find the tendency of the sander;

We need to apply the right-hand rule torque; whereby we consider the direction of the flywheel, the direction at which the torque is acting, and the movement of the sander toward the right.

Since the flywheel of the sander is in counterclockwise movement, hence the torque direction will be outward placing on the wall. However, provided that the movement of the sander is toward the right, then there exists an opposite force that turns downward which showcases the tendency in the sander is downward.

A top fuel dragster with a mass of 500.0 kg starts from rest and completes a quarter mile (402 m) race in a time of 5.0 s. The d

blsea [12.9K]

The average power needed to produce this final speed is 1069.1 hp.

Mass of the dragster, m = 500.0 kg,

Displacement travelled by the dragster, s = 402 m,

Time taken in this travel, t = 5.0 s,

Final velocity of the dragster, v = 130 m/s.

Let the initial velocity of the dragster be u and acceleration be a.

Using kinematical equation, s = ut + (1/2)at^2.

402 = u*5 + (1/2)*a*5^2
