<h3>What is Physics?</h3>

Física es un término que proviene del griego physis y que significa “realidad” o “naturaleza” y por eso también podemos definirla como la ciencia que estudia las propiedades del espacio, el tiempo, la materia, la energía y sus interacciones.

<h3>What is the amount?</h3>

It is a measurable property that admits degrees of comparison and represents either a count of the number of elements in a set, or the result of a physical measurement of a magnitude.

Tarzan swings on a 36.0 m long vine initially inclined at an angle of 31.0◦ with the vertical. The acceleration of gravity if 9.
aleksandrvk [35]

Answer:

  v = 10 m/s

Explanation:

Given,

Length of the vine, l = 36 m

Angle of inclination = 31.0◦ with the vertical

acceleration due to gravity = 9.81 m/s²

Using Conservation of energy

      KE = PE

 \dfrac{1}{2} mv^2 = m g h

v = \sqrt{2gh}

v = \sqrt{2 g l(1-\cos \theta)

v = \sqrt{2\times 9.81\times 36 \times (1-\cos 31^0)

  v = 10 m/s

Hence, the speed of the swing is equal to 10 m/s

how much thermal energy is absorbed by a copper water pipe with a mass of 2.3kg when its temperature is raised from 20.0 to 80.0
Sphinxa [80]

Explanation:

q = mCΔt

q = (2.3 kg) (385 J/kg/K) (80.0°C − 20.0°C)

q ≈ 53,000 J

q ≈ 53 kJ

compare 51.5 hectograms to 51500 decigrams. How do each of these values compare to a gram, and which represents a larger mass?
Olin [163]
These values when compared seem to be the same. They are equal. If we convert them to the same units, they results to the value which is:
 
51.5 Hectograms = 5100 Grams

51,500 Decigrams = 5100 Grams


Hope this answers the question. Have  a nice day.
