Which of the following is NOT a characteristic of scientific knowledge? please help me

2 answers:

8 0

Answer: "Scientific knowledge can answer all of society's questions" this is not a characteristic of scientific knowledge.

Explanation: Scientific knowledge is durable in most cases, this is true because the things demonstrated with science usually can be repeated by another scientist, so this knowledge is actually durable. But there are cases where the knowledge has a little mistake, ar a new discovery refutes one part of an older theory, so the knowledge can be changed or discarded in some cases.

For the other one, scientific knowledge can not answer all of the society's questions, where some of those, like "the meaning of life" or things like that need a more philosophical approach, so the second sentence is false.

I think the correct answer from the choices listed above is the second option. It would be that scientific knowledge can answer all of society's questions that is not a <span>characteristic of scientific knowledge. Hope this answers the question. Have a nice day.</span>

Two students are balancing on a 10m seesaw. The seesaw is designed so that each side of the seesaw is 5m long. The student on th

Lapatulllka [165]

Answer:

Option A. 4 m

Explanation:

Please see attached photo for diagram.

In the attached photo, X is the distance from the centre to which the student on the right must sit in order to balance the seesaw.

Clockwise moment = X × 45

Anticlock wise moment = 3 × 60

Clockwise moment = Anticlock wise moment

X × 45 = 3 × 60

X × 45 = 180

Divide both side by 45

X = 180 / 45

X = 4 m

Thus, the student must sit at 4 m from the centre.

A 30.0 kg box is placed on a 3.00 m tall shelf. What how much work was done on the box?

Kruka [31]

Answer:

W = 882.9[J]

Explanation:

In order to be able to calculate the work, we must first calculate the force necessary to lift the box. Since the necessary force is equivalent to the weight of the box, we can determine the weight of the box by means of the product of mass by gravitational acceleration.

$w = m*g\\$

where:

w = weight [N]

m = mass = 30 [kg]

g = gravity acceleration = 9.81 [m/s²]

$w = 30*9.81\\w = 294.3 [N]$

Now, the work can be calculated multiplying the force (weight) by the distance [m]

$W = w*d\\W = 294.3*3\\W=882.9[J]$

A siren on the top of the police car emits sound at frequency of 823 Hz. The car is approaching a bystander on a sidewalk at spe

statuscvo [17]

Answer:

The bystander will hear a frequency of 931.18 Hz.

Explanation:

let V = 39.5 m/s be velocity of the police car and Fs be the frequency a siren of the police car emits. let v = 0 m/s be the velocity of the bystander and Vs = 340 m/s is the velocity of sound in air.

then, we know that the bystander has to hear a higher frequency than the one emitted and the frequency that the bystander hears is given by the doppler relation:

Fo = [(Vs)/(Vs - V)]×Fs

= [(Vs)/(Vs - V)]×Fs

= [(340)/(340 - 39.5)]×(823)

= 931.18 Hz

Therefore, the bystander will hear a frequency of 931.18 Hz.
