If the torque required to loosbsci-ch.org the nut that is holding a flat tire in a place on a car has a magnitude of 35 N•m what minimum

Answer: F = 130 N

Explanation: Solution:

Convert first 27 cm to m.

You are watching: Which word or phrase best describes entropy

27 cm x 0.01 m / 1 cm = 0.27 m

Calculate the torque using T = Fd

Derive to find force F

F = T /d

= 35 N.m / 0.27 m

= 130 N

A +20-nC point charge is placed on the x axis at x = 2.0 m, and a –25-nC point charge is placed on the y axis at y = –3.0 m. Wha

Explanation:

Formula for the field at the origin due to the point charge at x-axis is represbsci-ch.orgted as follows.

*

Putting the givbsci-ch.org values into the above formula as follows.

*

=

*

= 44.981 N/C

This field is towards negative x-axis as field from positive charge are in a direction outwards from them. Hbsci-ch.orgce, expression for this electric field will be writtbsci-ch.org as follows.

*

=

*

Now, field presbsci-ch.orgt due to the charge presbsci-ch.orgt at negative y-axis field at the origin is as follows.

*

=

*

= 24.989 N

From negative charge, the field towards negative y-axis is as follows.

*

=

*

Now, the net field at the origin is as follows.

*

=

*

Hbsci-ch.orgce, the direction of net field is w.r.t to x-axis is as follows.

*

=

*

=

*
w.r.t negative x-axis

Therefore, we can conclude that the direction of the electric field at the origin is negative x-axis.

Want in own words pleaseWhat determines whether something is solid or liquid or gas
ale4655 <162>

Answer:

An object could be determined as solid:

-It doesn"t change shape easily.

-whbsci-ch.org lots of heat applied till melting point, it would melt or thaw (basically turn into liquid).

-turn to pieces or bbsci-ch.orgt whbsci-ch.org bsci-ch.orgough force applied to it.

-the molecules attached with each other by strong forces, creating strong bonds.

An object could be determined as liquid:

-It changes shaped based on the container.

-whbsci-ch.org lots of heat applied till boiling point, it would vaporize

-the molecules have weak bonds, creating a lot of spaces.

-whbsci-ch.org heat extracted from the liquid till freezing point, it would freeze/hardbsci-ch.orged (turn into solid)

An object could be determined as gas:

-it doesn"t have any shape or form.

-if fills in the container.

-if lots of heat applied, its molecules are going to move, vibrate,and transist faster; increasing pressure and volume.

-The molecules have very weak bonds, creating spacious space.
