A force of 15 newtons is applied to both Object A with a mass of 25 kilograms and Object B with a mass of 50 kilograms. What is true about the acceleration of Object A and Object B?

Answers

To analyze the differences in acceleration of the two objects, a necessary formula/relation to remember here is force = mass * acceleration. Given the different data in the problem, we can solve for the acceleration of each object. This is shown below:

Force = 15 N
M1 = 25 kg
M2 = 50 kg
a1 = ?
a2 = ?

For object 1:

15 N = 25 kg * a
a = 0.6

For object 2:

15 N = 50 * a
a = 0.3

Therefore, the acceleration of Object B is half that of Object A.

A car speeds up from rest to +16 m/ s in 4s. calculate the acceleration

Answers

The magnitude of acceleration is (change in speed) / (time for the change).

Change in speed = (speed at the end) - (speed at the beginning) =

(16 m/s) - (0) = 16 m/s .

Time for the change = 4 s .

Magnitude of acceleration = (16 m/s) / (4 s) = 4 m/s per sec = 4 m/s² .

16 m/s - 0 m/s divided by 4s
= 16 m/s divided by 4s
= 4 m/s
The acceleration is 4 m/s squared

A 4.00 kg stone is dropped from a height of 145 m. What is the stone’s potential and kinetic energy respectively when it is 50.0 m from the ground?A - 1,960 J, 5,680 J

B - 5,680 J, 1,960 J

C - 3,720 J, 1,950 J

D - 1,960 J, 3,720 J

Answers

Answer:

C - 3,720 J, 1,950 J

Explanation:

Hello

Epotential = M*G*H

Ep = (4)(9.8)(145-50)

Ep = 3729 J

Then

Ec = 1950 J

Which of the following states that absolute zero cannot be reached?A. the second law of thermodynamics
B. the first law of thermodynamics
C. the second and third laws of thermodynamics
D. the third law of thermodynamics

Answers

The second and third laws of thermodynamics states that absolute zero cannot be reached. The correct option among all the options that are given in the question is the third option or option "C". Both the laws actually deal with the relations that exist between heat and other forms of energy. I hope the answer helps you.

Answer:

D. the third law of thermodynamics

Explanation:

As per third law of thermodynamics we know that entropy of a perfect crystal comes to zero when the temperature of the crystal reaches to absolute zero.

So as per the theory of entropy we know that entropy of a system cannot be zero as it will reach zero then system will not exist.

So here we can say that

As per third law it is not possible to achieve zero kelvin or absolute zero temperature because at that temperature the entropy will become zero and then the system will not exist in that case.

So here we can say the correct answer will be

D. the third law of thermodynamics

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:

Verbal Phrase: named Robert

Type: participial
