do you think that this method of identifying unknowns would be effective for identifying any unknown element?

Answers

Answer 1

Answer: Unknowns, represented by variables, are effective for identifying the value. They stand for a certain amount, and solving for them would uncover values, like force etc.

Which of the following is not an example of kinetic energy being converted to potential energy?

Answers

You did not give any answers to choose from. So I'll just explain to you what the difference is.

Kinetic energy means the object is in motion, or is moving.

Potential energy means the object is not moving, but it has the potential to.

Example:
You are holding your phone in your hand one foot above the ground and you are not moving it at all (Potential energy). You then drop your phone and it begins to fall (Kinetic energy).

Now, you hold your phone in your hand 6 feet above the ground and you are not moving it at all (More Potential energy). You then drop your phone and it begins to fall.. very very hard... (More Kinetic Energy).

The velocity of a car traveling in a straight line increases from 0 meters/second to 30 meters/second in 8 seconds. What is the average acceleration of the car?

Answers

Answer : $a=3.75\ m/s^2$

Explanation :

Initial velocity of the car, u = 0 m/s

Final velocity of the car, v = 30 m/s

Time taken, t = 8 s

Average acceleration of the car is defined as the change in velocity divided by time.

$a=(v-u)/(t)$

$a=(30\ m/s-0)/(8\ s)$

$a=3.75\ m/s^2$

Hence, this is the required solution.

Average acceleration is how much the car increases (on average) per second. So, since it increases by 30 m/s in 8 s, then dividing 30 by 8 will give you an average acceleration of 3.75 m/s^2 (remember that acceleration is ever increasing, so the unit is s^2, not just s)

Hope this helps!

Activity that a person habitually engages in to earn a living is activity that persons looking for job engage in.

Activity in which one utilises strength or faculties to do or do anything. a particular duty, responsibility, function, or assignment that often forms a component or stage of a bigger action.

Thus, Joule is the SI unit of work (J). The work accomplished by a force of one newton creating a displacement of one metre is known as a joule.

Verb phrases are verbs that may function as a predicate, adjective, or adverb.

(a) "That he said" is an adjective modifying "word". However, this contains the s ubject"he" and the verb "said". It is a clause and NOT a phrase. Phrases can only have either a verb or a noun.
(b) There's only one verb "was" but it does not come with a complement, object, modifier, or other verb. Hence, it's NOT a verb phrase.
(c) "Shall be" consists of the modal shall and the be-verb be. This is a perfect example of a verb phrase that functions as a VERB PHRASE.
(d) "Roared" and "charged" are two verbs referring to different subjects. They do not come with a complement, object, modifier, or another verb. Hence, they're NOT a verb phrase. "As the bull charged" is a clause and not a phrase.

The correct answer is:
