A sample of chlorine has two naturally occurring isotopes. The isotope Cl-35 (mass 35.0 amu) makes up 75.8% of the sample, and t
irinina [24]

Answer:

M_{av}=35.521amu

Explanation:

As in any sample you will have 75.8% of Cl-35 iosotopes and 24.3% of Cl-37 iosotopes you can get the average atomic mass as:

M_{av}=(35amu*75.8+37amu*24.3)/100=35.521amu

xenn [34]
<span>The expected boiling point of a substance increases with an increasing molar mass of the substance. So I would expect the lighter compounds to boil at lower temperature. Also more polar molecules tend to boil at higher temperature. Pentane is the lightest of all three compounds, so it should boil the soonest. Heptane is a lot heavier than Pentane, but slightly lighter than Heptanol. So it should boil next. Heptanol is the heaviest of all of the molecules and is also quite polar compared to heptane. So it should have the highest of all the boiling points.</span>

At what minimum speed must a roller coaster be traveling when upside down at the top of a circle so that the passengers do not f
worty [1.4K]

Answer:

v_{min} \approx 17.153\,\frac{m}{s}

Explanation:

The roller coaster begins with maximum kinetic energy and no gravitational potential energy. The gravitational potential energy reaches its maximum when roller coaster is upside down at the top of the circle. The physical model for the roller coaster is constructed by means of the Principle of Energy Conservation:

\frac{1}{2}\cdot m \cdot v_{min}^{2} = m\cdot g \cdot h

The minimum velocity is:

v_{min} = \sqrt{2\cdot g \cdot h}

Let assume that radio of curvature is measured in meters. Hence:

v_{min} = \sqrt{2\cdot (9.807\,\frac{m}{s^{2}} )\cdot(15\,m)}

v_{min} \approx 17.153\,\frac{m}{s}

A truck skids for a distance of 25m with the road pushing on its tires with force of 1500N as its brakes are applied. What is th
Daniel [21]

Answer:

37500 J

Explanation:

Law of conservation of energy: Its states that energy can neither be created nor destroyed but it can be transformed from one form to another.

Applying the law of conservation of energy.

The change in kinetic energy for the truck  =  Net work done by the truck skids

ΔK.E = F×d.................... Equation 1

Where ΔK.E = Change in kinetic energy, F = Force, d = distant.

Given: F = 1500 N, d = 25 m

Substitute these values into equation 1

ΔK.E = 1500×25

ΔK.E = 37500 J
