Answer:
Explanation:
For example, an ice cube has heat energy and so does a glass of lemonade. If you put the ice in the lemonade, the lemonade (which is warmer) will transfer some of its heat energy to the ice.
The support of the State governments in all their rights…I consider one of the essential principles of our Government… How is Jefferson's view reflected in the U.S. Constitution? The U.S. Constitution lists all powers given to the states. The U.S. Constitution gives unlimited power to the states. The U.S. Constitution says powers not given to the federal government belong to the states. The U.S. Constitution gives unlimited power to the federal government and little to the states.
Answer:
The Correct Answer is
The U.S. Constitution says powers not given to the federal government belong to the states.
Explanation:
In the paragraph, Jefferson states defending the rights of states is one of the fundamental, or most significant, policies of our administration. Did that get you to remember the Tenth Amendment? It restrains the authority of the central government, defending the rights of states. It states that the central government only has the authorities listed in the Constitution. Unlisted authorities belong to the states.

To celebrate a victory, a pitcher throws her glove straight up into the air with an initial velocity of 6.0 m/s. What is the maximum height of the glove? (Show work)
Answer:
h = 1.8 m
Explanation:
The initial velocity of the glove, u =- 6 m/s
We need to find the maximum height of the glove. Let it is equal to h. Using equation of kinematics. At the maximum height v = 0
[tex]v^2-u^2=2ah[/tex], h is the maximum height and a = -g
[tex]0^2-(6)^2=2\times (-10)\times h\\\\h=\dfrac{36}{20}\\\\h=1.8\ m[/tex]
Hence, it will go up to a height of 1.8 m.

Which of these warnings refers to a chemical property of the material?
Answer:
Please show the warning's
Explanation:
The warning refers to the chemical property of the material or object that is flammable.
What is Chemical Property?A chemical property is a feature that pertains to how a component, such as an ingredient or a compound, can alter as a result of a reaction. Due to bonding and other atomic structural characteristics, a substance develops these qualities as a result of its chemical identity.
Tactile or visual changes may occur in conjunction with chemical qualities. Chemical reactions commonly involve popping, fizzing, or the release of brilliant light. The emission of heat may also be a sign of a chemical reaction or chemical conversion that is taking place. Because the connections in the atomic structure are changing or breaking, these sensory clues appear.
Therefore, the warning refers to a chemical property of the material is flammable or combustible.

FiltrationMagnitizationeverpouration to drynessA student weighs 530 N. The walk to the top of a 3m staircase. It takes them 5 seconds. How
much work did they do?
*
Answer:
W = 1590 J
Explanation:
We could use the formula of potential energy to find work as both have the same units,
W = mgh
since weight = mg so,
Work = weight x height
= 530 x 3
= 1590 J
Answer:
The work will be 1590 J
since the formula is W = F x D so I cancel the time
Explanation:
Given:
(Force) F = 530N
(Distance)D = 3m
Unknown:
W or Work
Formula and Solution:
W = F x D
W = (530N) (3m)
Final Answer:
W = 1 590 N·m or simplify as 1590 J

Spring A has a spring constant of 5 N/m and spring B has a force constant of 9 N/m. A weight of 2 kg is applied to spring A and a weight of 10 kg is applied to spring B. Which of the following is true for the final displacements of springs A and B?
a) Spring B has a larger displacement than spring A. b) Spring A has a larger displacement than spring B. c) Spring A and spring B have the same displacement.
Answer: Option A.
Spring B has a larger displacement that spring A.
Explanation:
Spring B has a larger displacement that spring A .
By using Hooke's law.
F=-Kx
Where F is force, K is spring constant and x is displacement.
For spring a
Weight / force is 2 kg
Spring constant (K) is 5/nm
Therefore,
F=-Kx
2=-5x
X=2/-5
X= -0.4m
For spring B.
Weight is 10Kg
Spring constant is 9N/m
F=-Kx
10=-9x
X=-10/9
=-1.1m
Therefore Spring B have larger displacement than spring A.
In Hooke's law, negative sign that is present on the spring's force indicate that the force exerted by the spring opposes the spring's displacement.
it takes 275n to set a stationary 77.3 crate in motion. what is the coefficient of static friction?
Note: I'm assuming the data 77.3 is the mass of the crate.
Answer:
[tex]\mu_s =0.36[/tex]
Explanation:
The coefficient of static friction, called \mu_s is the ratio between the force needed to start moving an object above a rough surface (Fr), and the normal force the surface exerts on the object (N).
[tex]\displaystyle \mu_s =\frac{Fr}{N}[/tex]
The normal force is numerical equivalent to the weight of the body if no other external forces are acting.
[tex]N=m\cdot g[/tex]
The mass of the crate is m=77.3 Kg, thus its weight and normal force is:
[tex]N=77.3\ kg\cdot 9.8\ m/s^2[/tex]
[tex]N= 757.54\ Nw[/tex]
Now we calculate the coefficient:
[tex]\displaystyle \mu_s =\frac{275\cancel{N}}{757.54\cancel{N}}[/tex]
[tex]\boxed{\mu_s =0.36}[/tex]

When you cook a marshmallow on a metal poker tool over an open flame, energy is transferred. Identify the three different ways thermal energy is transferred in this situation. Be sure to name the specific places or phenomenon in this system where each of the types of thermal energy transfer is occurring and the direction the energy is being transferred (from what to what).
Answer:
The three ways thermal energy is transferred are;
1) Conduction
2) Convection
3) Radiation
Explanation:
1) The conduction of the heat from the open flame to the marshmallow is through the direct contact of the flame with the marshmallow, such that the flame the region of the combustion reaction, that produces light and heat touches the marshmallow
2) The convection process is the transfer of heat from the rising heated combustion products, as well as the heated air that rises from the flame
3) The radiation heat transfer is the transfer of the heat from the fire to the marshmallows directly by the heat the moves in the form of electromagnetic waves at temperatures above 1000 K, without the need for a medium, such that the marshmallow can be heated by the heat coming from side of the flame.
if 270 watts of power is used in 42 seconds, how much work was done
Answer: W = 11340J
Explanation:
Hey there! I will give the following steps, if you have any questions feel free to ask me in the comments below.
So this is the Formula: Power = Work / Time.
Step 1: Find the Formula
P = W / T
Step 2: Make W the subject of the equation.
W = PT
Step 3: Given.
P = 270 Watts, T = 42 seconds
Step 4: Substitute these values into equation 2 .
W = 270(42)
Step 5: Simplify.
W = 11340J
The amount of work done was 11340.

Answer:
[tex]the \: net \: force = \: 50 - 15 = 35.[/tex]
Answer:
Net force is going to be GREATER FORCE - LESS FORCE if they are working in opposite direction

describing motion with position distance vs time graphs
Answer:
In a position-time graph, the velocity of the moving object is represented by the slope, or steepness, of the graph line. If the graph line is horizontal, like the line after time = 5 seconds in Graph 2 in the Figure below, then the slope is zero and so is the velocity. The position of the object is not changing.
