How much work is done by 0.070 m3 of gas, when the volume remains constant with pressure of 63 x 105 Pa?

ICE Princess25 [194]

Answer:

W = 0 J

Explanation:

The amount of work done by gas at constant pressure is given by the following formula:

$W = P\Delta V$

where,

W = Work done by the gas

P = Pressure of the gas

ΔV = Change in the volume of the gas

Since the volume of the gas is constant. Therefore, there is no change in the volume of the gas:

$W = P(0\ m^3)\\$

In attempting to pass the puck to a teammate, a hockey player gives it an initial speed of 2.8 m/s. However, this speed is inade

erastova [34]

Answer:

3.95979 m/s

Explanation:

t = Time taken

u = Initial velocity

v = Final velocity

s = Displacement

a = Acceleration

$v^2-u^2=2as\\\Rightarrow as=\frac{v^2-u^2}{2}\\\Rightarrow as=\frac{0^2-2.8^2}{2}\\\Rightarrow as=-3.92$

Here $s=\frac{1}{2}s$

$\\\Rightarrow as=-7.84\ m/s^2$

$v^2-u^2=2as\\\Rightarrow -u^2=2as-v^2\\\Rightarrow u=\sqrt{v^2-2as}\\\Rightarrow u=\sqrt{0^2-2\times -7.84}\\\Rightarrow u=3.95979\ m/s$

Initial velocity of the puck should be 3.95979 m/s

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).
