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.
A circuit has a 24 volt battery and a resistor that is 8 ohms. How many amps are running through the circuit?
Answer:
3 A
Explanation:
Using Ohm's law, [tex]I=\frac {V}{R}[/tex] where I is the current in Amps, V is the voltage in V and R is resistance through the resistor in Ohms
Substituting v for 24 V and I for 8 Ohms we obtain
[tex]I=\frac {24 V}{8}=3 A[/tex]
Therefore, 3 A run through the circuit
The amount of current that is running through this circuit is equal to 3 Amperes.
Given the following data:
Voltage = 24 volt.
Resistance = 8 ohms.
How to calculate the amount of current?In order to determine the amount of current that is running through this circuit, we would apply Ohm's law:
V = IR
Where:
I is the current.R is the resistance.V is the voltage.Substituting the given parameters into the formula, we have;
24 = I × 8
I = 24/8
Current, I = 3 Amperes.

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.

length of the nichrome wire = ?
Solution:
To find the length of the nichrome wire, we use the expression below:
L = \frac{RA}{P}PRA
where l is the length of the wire
R is the resistance of the wire
A is the area
p is the resistivity
Now we need to convert area from mm to m;
1000mm = 1 m
1mm² = 1 x \frac{1m}{1000mm} x \frac{1m}{1000mm}1000mm1mx1000mm1m = 1 x 10⁻⁶m²
Input the values in the formula;
L = \frac{100 x 10^{-6} x 1 x 10^{-6} }{10}10100x10−6x1x10−6 = 1 x 10⁻¹¹m²

If an airplane was experiencing a thrust force of 450 N and there was a drag of 200 N. What would the resulting net force be?
thxx
Answer:
250 N
Explanation:
Drag opposes the direction of motion, so it points in the opposite direction of thrust. Therefore, the net force is:
∑F = 450 N − 200 N
∑F = 250 N

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.
If a worksite includes more than one set of management and workers, who should have access to the information, training, and controls needed to avoid workplace accidents?
To collaboratively reduce workplace accidents and promote a cooperative safety culture, information, training, and controls should be made available to all levels of management and employees from all teams.
All relevant staff, regardless of their hierarchical positions, should have access to information, training, and controls to prevent workplace accidents at a company with different sets of management and employees.
In order to enable proactive hazard detection and risk mitigation, a comprehensive approach to safety entails exchanging essential information and training across teams.
Thus, a collaborative safety culture can be established, resulting in a safer work environment for everyone engaged and a team effort in accident prevention, by making sure that all levels of management and employees have the appropriate knowledge and tools.
