Which of the following best describes what happens when ice is placed in a warm glass of water?
A. The ice floats to the top, but small pieces break off and are suspended in the liquid to cool it through convection
B. Heat from the glass moves through the liquid to melt the ice through radiation
C. The heat from the surrounding liquid is transferred to the ice through conduction
D.The ice transfers the cold temperature to the surrounding water through convection
Heat from surrounding water is transferred to the ice through conduction, leading to an increase in energy of the ice molecules and causing the ice to melt.
Explanation:When ice is placed in a warm glass of water, the correct description of what happens is that heat from the surrounding liquid is transferred to the ice through conduction. The water molecules around the ice have more kinetic energy compared to the molecules within the ice. As the energy transfer occurs, the water molecules transfer some of their kinetic energy to the ice molecules, which increases their energy and eventually leads to the melting of the ice.

1. A test specimen in a tensile test has a gage length of 2.0 in and an area = 0.5 in2. During the test the specimen yields under a load of 32,000 lb. The corresponding gage length = 2.0083 in. This is the 0.2 percent yield point. The maximum load of 60,000 lb is reached at a gage length = 2.60 in. Determine (a) yield strength, (b) modulus of elasticity, and (c) tensile strength. (d) If fracture occurs at a gage length of 2.92 in, determine the percent elongation. (e) If the specimen necked to an area = 0.25 in2, determine the percent reduction in area.
The yield strength is 64,000 psi, modulus of elasticity is approximately 15,422,000 psi, tensile strength is 120,000 psi, percent elongation is 46%, and percent reduction in area is 50% for the given tensile test specimen.
Explanation:The question pertains to the calculation of various material properties from a tensile test. Specifically, we are looking to find the yield strength, modulus of elasticity, and tensile strength of a test specimen with given gage lengths and loads. Additionally, we will determine the percent elongation and percent reduction of area based on the provided gage lengths and areas before and after fracture.
Calculations:Yield Strength: Yield strength is calculated as the load at which the material begins to deform permanently divided by the original cross-sectional area. Thus, yield strength = load / original area = 32,000 lb / 0.5 in2 = 64,000 psi.Modulus of Elasticity: Modulus of elasticity (Young's modulus) is a measure of the elasticity of a material and can be determined by the formula E = stress/strain. Here, E = (32,000 lb / 0.5 in2) / ((2.0083 in - 2.0 in) / 2.0 in) = 64,000 psi / 0.00415 = approximately 15,422,000 psi.Tensile Strength: Tensile strength is the maximum stress the material can withstand while being stretched or pulled before necking. For this specimen, tensile strength = maximum load / original area = 60,000 lb / 0.5 in2 = 120,000 psi.Percent Elongation: Percent elongation is an indication of ductility and is expressed as ((final gage length - initial gage length) / initial gage length) x 100%. Thus, percent elongation = ((2.92 in - 2.0 in) / 2.0 in) x 100% = 46%.Percent Reduction in Area: Percent reduction in area represents how much the cross-sectional area of a material decreases under tensile stress and is calculated as ((original area - reduced area) / original area) x 100%. Subsequently, the percent reduction in area = ((0.5 in2 - 0.25 in2) / 0.5 in2) x 100% = 50%.a) The yield strength is 64,000 psi
b) The modulus of elasticity is 15,421,686.75 psi
c) The tensile strength is 120,000 psi.
d) The percent elongation at fracture is 46%
e) The percent reduction in area is 50%.

Which of these is a characteristic of a reform movement?
A reform movement is one that seeks specific changes within the social structure, for instance, advocating for rights and freedoms, without advocating for a complete overhaul of society.
Explanation:A characteristic of a reform movement is that it seeks to change something specific about the social structure, rather than seeking a complete overhaul of society like revolutionary movements or focusing on inner change like religious movements. Reform movements, such as the anti-slavery movement or the women's rights movement of the 1820-1840 period, work to address societal issues and improve conditions within existing frameworks, advocating for a greater body of rights and freedoms. These movements may focus on aspects such as temperance, anti-nuclear advocacy, or civil rights, and they derive from a practical observation of real-world problems rather than supernatural beliefs.
Notable historical examples of reform movements include the efforts of advocates like William Lloyd Garrison and Frederick Douglass during the early 19th century, who diligently worked towards abolishing slavery and advancing women's rights. Similarly, the social gospel movement showcased reform within religious institutions, focusing on applying Christian ethics to labor reform and poverty alleviation.

Maintain a distance of at least _____ between your vehicle and the vehicle behind you
A
Maintain a distance of at least __2___ between your vehicle and the vehicle behind you.
Explanation:
As the car infront passes a stationary object like a lamp post, the driver in the car behind should count at least two- seconds before their car reached and passes the stationary object too. This two-second rule ensures that cars maintain a safe distance between each other to avoid tailgaiting and collisions.
This rule leaves at least some room for the drivers to react swiftly enough, and avoid collisions, in case the car infront holds emergency breaks. It is even recommended that more seconds are used in hazardous conditions such as fog and slippery roads.
