Answer:

Volume of gasoline that expands and spills out is 1.33 ltr

Explanation:

As we know that when temperature of the liquid is increased then its volume will expand and it is given as

\Delta V = V_o\gamma \Delta T

here we know that

V_o = 40 Ltr

volume expansion coefficient of the gasoline is given as

\gamma = 950 × 10^{–6}

change in temperature is given as

\Delta T = (131 - 68) \times \frac{5}{9}

\Delta T = 35 ^oC

Now we have

\Delta V = 40(950 \times 10^{-6})(35)

\Delta V = 1.33 Ltr

  • <em>I</em><em>t</em><em>'</em><em>s</em><em> </em><em>i</em><em>n</em><em>c</em><em>o</em><em>r</em><em>r</em><em>e</em><em>c</em><em>t</em><em> </em><em>s</em><em>e</em><em>n</em><em>t</em><em>e</em><em>n</em><em>c</em><em>e</em><em>.</em>
  • As we know that, rubber are an insulators of electricity, and they do not not have free ions which can help in conducting electricity.

<h3>b)</h3><h3><u>Q</u><u>u</u><u>e</u><u>s</u><u>t</u><u>i</u><u>o</u><u>n</u><u>:</u><u>-</u></h3>
  • Electroplating wastes are useful to human health and environment.
<h3><u>Answer</u><u>:</u><u>-</u></h3>
  • <em>It's</em><em> </em><em>incorrect</em><em> </em><em>sentence</em><em>.</em><em> </em>
  • As we know that, electroplating of substances releases harmful and toxic substances into the environment causing serious health issues in human, so it's waste substances released into environment can have very harmful effects.

<u>So correct sentence is:</u>

  • <em>Electroplating wastes are </em><em>harmful</em><em> </em><em>to human health and </em><em>environment</em><em>.</em>

<h3>c)</h3><h3><u>Question</u><u>:</u><u>-</u></h3>
  • In an LED bulb, the shorter lead is connected to the positive terminal of the battery.
<h3><u>Answer</u><u>:</u><u>-</u></h3>
  • <em>It's incorrect sentence. </em>
  • As we know that, in an LED bulb their are two terminals that is the positive and the negative. So here the lead connected to the positive terminal is always slightly longer than the lead connected to negative terminal of the bulb.

<u>So correct sentence is:</u>

  • <em>In an LED bulb, the </em><em>longer</em><em> lead </em><em>i</em><em>s</em><em> </em><em>connected to the positive terminal of the battery.</em>

<h3>d)</h3><h3><u>Question</u><u>:</u><u>-</u></h3>
  • Pure water conducts electricity.
<h3><u>Answer</u><u>:</u><u>-</u></h3>
  • <em>It's incorrect sentence. </em>
  • As we know that, pure water is a form of H2O where Hydrogen (H) is positive ion and Oxygen (O) is a negative ion which can conduct electricity when they are in individuals but as in pure water they are in combined form of compound H2O in which they become neutral and can't conduct any electricity.

<u>So correct sentence is:</u>

  • <em>P</em><em>ure water </em><em>c</em><em>a</em><em>n</em><em>'</em><em>t</em><em> </em><em>conduct</em><em> </em><em>electricity.</em>

A force of 100 N acts upward. Resolve this force into 2 components; one that acts 30º north of west and one that acts 60º north
GrogVix [38]

To resolve these forces we have to make use of the sines and cosines.

To resolve this force in 30 degree north of west, the answer will be

100*sin(30)

The answer will be 50N

Now to resolve the force acting 60 degree north of east

100* cos(60)

The answer will be 50N.

This also adds to the total force acting that is 50+50=100N. This is the way forces are resolved according to their specified angles.
