Answer:

Mass of object = 8kg

Explanation:

<em>Since</em><em> </em><em>a</em><em>=</em><em> </em><em> </em><em>change</em><em> </em><em>in</em><em> </em><em>v</em><em>/</em><em> </em><em>change</em><em> </em><em>in</em><em> </em><em>t</em><em>,</em><em> </em><em>a</em><em>=</em><em> </em><em>(</em><em>1</em><em>8</em><em>-16</em><em>)</em><em>/</em><em>2</em>

<em>=</em><em> </em><em>1.5</em>

<em>And</em><em> </em><em>F</em><em>=</em><em>ma</em><em> </em>
<em>Force</em><em> </em><em>=</em><em>1</em><em>2</em>
<em>a</em><em>=</em><em> </em><em>1.5</em>
<em>m</em><em>=</em><em>?</em>

<em>You</em><em> </em><em>can</em><em> </em><em>now</em><em> </em><em>solve</em><em> </em><em>for</em><em> </em><em>your</em><em> </em><em>unknown</em><em> </em><em>value</em><em> </em><em>of</em><em> </em><em>mass</em><em>.</em>

Static cling makes your clothes stick together. what causes this to happen? 1. external forces to the clothes 2. forces of natur

djyliett [7]

This phenomenon is as a result of static friction created by the tumbling clothes. Static friction results from the rubbing together of two or mores objects or body and electrons are stripped from one surface of the clothes more than the other. This creates an electrostatic force of attractions between the positive charges on one cloth and the negative charges on the other cloth.(unlike charges attract).

A spring whose spring constant is 270 lbf/in has an initial force of 100 lbf acting on it. Determine the work, in Btu, required

cricket20 [7]

Answer:

0.02585 BTU

Explanation:

Given: Spring constant, k = 270 lbf/in

Initial force, f =100 lbf

Compression, x = 1 in

Work done can be calculated as follows:

$W = \int {(f+kx)} \, dx \\W = fx + \frac{1}{2}kx^2\\W= (100 lbf)(1 in)+ \frac{1}{2}(270 lbf/in)(1 in)^2\\W= 100+135 = 235 lbf in\\W=235 \times 0.00011 BTU = 0.02585 BTU$
