Find the Horizontal (x) vector for these forces.

Physics
1 answer:
Anestetic [448]2 years ago
6 0

Answer:

See the explanation below.

Explanation:

The force is a vector therefore we can decompose the force into components x & y. as we need the horizontal component of the force, we must use the cosine function of the angle.

F_{1x}=30.8*cos(20)\\F_{1x}=28.94[N]\\F_{2x}=34.3*cos(20)\\\\F_{2x}= 32.23[N]

Why is the sky blue?
Taya2010 [7]
A clear cloudless day-time sky is blue because molecules in the air scatter blue light from the sun more than they scatter red light. When we look towards the sun at sunset, we see red and orange colours because the blue light has been scattered out and away from the line of sight.

When a solid is in the process of changing into a liquid and extra energy is added to the system, the temperature does not chang
Alekssandra [29.7K]

Answer:

D. The temperature does not change during a phase change because the average kinetic energy does not change. Therefore, the potential energy in the bonds between molecules must change.

Explanation:

When there is a change of state (for example, from solid into a liquid, as in this example), when energy is added to the system, the temperature of the substance does not change.

The reason for this is that the energy supplied is no longer used to increase the average kinetic energy of the particle, but instead it is used to break the bonds between the different particles/molecules. For instance, since in this case the substance is changing from solid to liquid, all the energy supplied during the phase change is used to break the bonds between the molecules of the solid: when the process is done, all the molecules will be free to slide past each other, and the substance has turned completely into a liquid.

The bonds between molecules store potential energy: therefore, this means that the energy supplied during the phase change is not used to change the kinetic energy, but to change the potential energy in the bonds between the molecules.

To span the distance between two switches, why is adding an intermediate switch not an attractive choice
navik [9.2K]

Adding an intermediate switch is not an attractive choice to span the distance between two switches due to expense issues. It may have different ports.

<h3>What is a network switch?</h3>

A switch refers to a hardware tool capable of connecting different computer devices in a network.

A network switch can connect devices on a network by centralizing communications among many devices in a given local area network.

A switch may support different speeds for transmission of data (for example, one gigabit Gbps per second).
