The sports car has a weight of 4900 lblb and center of gravity at GG. If it starts from rest it causes the rear wheels to slip a

s it accelerates. The coefficients of static and kinetic friction at the road are μsμs = 0.5 and μkμkmu_k = 0.35, respectively. Neglect the mass of the wheelDetermine how long it takes for it to reach a speed of 10 ft/s.What are the normal reactions at each of the rear wheels on the road?What are the normal reactions at each of the front wheels on the road?

I have a molten Ni-Cu alloy with 60 wt%Ni. (ii) I cool it down to a temperature where I have both solid and liquid phases. At th
SIZIF [17.4K]

Answer:

The percentage of the remaining alloy would become solid is 20%

Explanation:

Melting point of Cu = 1085°C

Melting point of Ni = 1455°C

At 1200°C, there is a 30% liquid and 70% solid, the weight percentage of Ni in alloy is the same that percentage of solid, then, that weight percentage is 70%.

The Ni-Cu alloy with 60% Ni and 40% Cu, and if we have the temperature of alloy > temperature of Ni > temperature of Cu, we have the follow:

60% Ni (liquid) and 40% Cu (liquid) at temperature of alloy

At solid phase with a temperature of alloy and 50% solid Cu and 50% liquid Ni, we have the follow:

40% Cu + 10% Ni in liquid phase and 50% of Ni is in solid phase.

The percentage of remaining alloy in solid is equal to

Solid = (10/50) * 100 = 20%

Why is apartments called apartments but there not apart???
Lisa [10]

Answer:

he word Apartment derives from the French apartment. ... An apartment came to be called so because it has individual/private rooms for different people, on the same floor. These rooms were, of course, apart. In Britain, apartments are called "flats", as everyone knows.

Answer:

The person responsible for the certifications could also be  criminally responsible.

Explanation:

In the text above we can notice the variation of the salmonela results tests in which implies that someone deliberately changed the certificates.

The person who emitted the certificates before the tests even been ready indicates an indirect influence on the decision, either through bribery or internal agreements, this shows that they would work in conjunction with Stewart Parnell  to release unsafe products.

A Sampling of 409 motor Shafts from a very large production Batch shows a sample standard deviation in Diameter of 0.021 mm with
andrezito [222]

Answer:

9.248 < \mu < 9.253 mm

Explanation:

Given data:

standard deviation  = 0.021 mm

sample mean = 9.251 mm

total sample = 409 m

confidence interval level = 95%

mean diameter of entire batch  \mu  = \bar X \pm z \frac{\sigma}{\sqrt{n}}

where

\bar X - sample mean = 9.251 mm

z = critical value

plugginf all value in the above relation to get the mean diameter

\mu = 9.251 \pm 1.96 \times \frac{0.021}{\sqrt{409}}

9.248 < \mu < 9.253 mm
