4 is G. BB and Bb because that is what you are analyzing the product of.

5 is C. The round shape is obviously a dominant trait since mixing with a wrinkled shape didn't have an effect. The wrinkled shape is recessive.

Which characteristic does inertia describe
nadezda [96]

Answer:

Inertia is the resistance of any physical object to any change in its velocity. This includes changes to the object's speed, or direction of motion. An aspect of this property is the tendency of objects to keep moving in a straight line at a constant speed, when no forces act upon them.

Nisha was making a list of things that are obtained from plants and Amol was making a list of things that can dissolve in water.
Allisa [31]

Answer:

Sugar

Explanation:

Nisha's list:                               Amol's list

  Jute                                          Vinegar

  Wood                                       Lemon juice

  Rubber                                   Cooking soda

Nisha's list is made up of things that can be derived from plants. From the list given, oil, sugar and cotton can also be obtained from plants.

Most plant materials are organic matter.

Amol's list is made up of things that can dissolve in water. Sugar and table salt can also be dissolved in water.

Water is able to dissolve these materials because they are polar compounds. One rule of solubility is that like dissolves like.

New list:

Nisha's list:                               Amol's list

  Jute                                          Vinegar

  Wood                                       Lemon juice

  Rubber                                   Cooking soda

  Sugar                                       Sugar

                                   

Only sugar from the list can be added to both lists. It can be obtained from plant and can also dissolve in water.

If A vector = i^-j^+k^ then unit vector in the direction of A vector
Novosadov [1.4K]

If <em>A</em> = <em>i</em> - <em>j</em> + <em>k</em>, then the magnitude of <em>A</em> is

||<em>A</em>|| = √(1² + (-1)² + 1²) = √3

Then the unit vector in the direction of <em>A</em> is 1/||A|| multiplied by <em>A</em> :

<em>u</em> = <em>A</em>/||<em>A</em>|| = (<em>i</em> - <em>j</em> + <em>k</em>)/√3

(choice D)

an object is shot vertically upward into the air with an initial velocity of 20 m/s? which of the following correctly describes
Drupady [299]

Answer:

Answer is (C)

Explanation:

<u>For</u><u> </u><u>acceleration</u>

• If the motion is vertically, then acceleration is 9.8 m/s²

» Upward motion, acceleration is negative (-9.8)

» Downward motion, acceleration is positive (+9.8)

<u>For</u><u> </u><u>velocity</u>

{ \rm{v = u + gt}} \\ { \rm{v = 20 + ( - 9.8 \times 4)}} \\  { \rm{v =  - 19.2 \: m {s}^{ - 1} }}
