Which of the following was/were used by the Greek philosophers in

Assoli18 [71]

Answer:

a and c are both correct

Explanation:

The Greek Philosophers had to reject many existing explanations (mostly from the babylonians and the egyptians) because of possible religion bias. <u>They resorted to logic and reason to provide understanding for the world around them</u>. The first set of Greek Philosophers were the Milesian thinkers; <u>whom aside from logic and reason also placed value on Observation in understanding the world</u>.

Two wires, each of length 1.3 m, are stretched between two fixed supports. On wire A there is a second-harmonic standing wave wh

UNO [17]

Answer:

Explanation:

Given

Length of each wire $L=1.3\ m$

On wire A second harmonic frequency is given by

$f_2_{a}=2\times (\frac{v}{2L})$

where f=frequency

v=velocity of wave

L=length of wire

$v_a=f_2\times L$

$v_a=640\times 1.3=832\ m/s$

For wire B third harmonic is given by

$f_3_{b}=3\times (\frac{v}{2L})$

$v_b=\frac{2L}{3}\cdot f_3_{b}$

$v_b=\frac{2\times 1.3}{3}\times 640=554.66\ m/s$

A bag of cement has a mass of 62 g. What is the mass of the bag of cement in S.I. units (kg)?

NNADVOKAT [17]

The mass of this bag of cement in S.I. units (kg) is equal to 0.062 kilograms.

<u>Given the following data:</u>

Mass of cement = 62 grams.

To calculate the mass of this bag of cement in S.I. units (kg):

<h3>How to convert to S.I. units.</h3>

In Science, kilograms (kg) is the standard unit of measurement or S.I. units of the mass of a physical object. Thus, we would convert the value of the mass of this bag of cement in grams to kilograms (kg) as follows:

<u>Conversion:</u>

1000 grams = 1 kilograms.

62 grams = X kilograms.

Cross-multiplying, we have:

X = $\frac{62}{1000}$

X = 0.062 kilograms.
