PLEASE HELP IM UNSURE OF WHAT THE ANSWER IS

katovenus [111]

Answer:

The horizontal forces (Cols 2 & 3) balance for W and Y.

The vertical forces (Cols 1 & 4) also balance for W and Y.

This is not true for either X (unbalanced horizontal forces) or

Z (also unbalnced horizontal forces)

An 1100-kg car traveling at 27.0 m/s starts to slow down and comes to a complete stop in 578 m. What is the magnitude of the ave

Trava [24]

Answer:

693.685 N

Explanation:

t = Time taken

u = Initial velocity = 27 m/s

v = Final velocity

s = Displacement = 578 m

a = Acceleration

m = Mass

Equation of motion

$v^2-u^2=2as\\\Rightarrow a=\frac{v^2-u^2}{2s}\\\Rightarrow a=\frac{0^2-27^2}{2\times 578}\\\Rightarrow a=-0.63062\ m/s^2$

Force

F = ma

$F=1100\times -0.63062\\\Rightarrow F=-693.6851\ N$

Magnitude of braking force required to stop the car is 693.685 N

The pressure and absolute temperature of an ideal gas are both tripled, the volume is __________. not changed

ankoles [38]

Answer:

Not Changed

Explanation:

To know what happened with the volume you need to know the Ideal gas Law

$\frac{P_{1}V_{1}}{T1} =\frac{P_{2}V_{2} }{T2}$

This law is a combination of the other four laws: Boyles's, Charles's, Avogadro's, and Guy-Lussac's.

The initial state is represented by P1, V1, T1 and the final by P2, V2, T2.

In this case:

$T_{2} =3T_{1} \\P_{2} =3P_{1}$

Replacing on the equation

$\frac{P_{1}V_{1}}{T1} =\frac{3P_{1}V_{2}}{3T_{1} }$

If we clear from the equation V2

$\frac{P_{1}V_{1}3T_{1}}{T_{1} 3P_{1}} ={V_{2}}$

Then cancel both P1 and T1

$\frac{3V_{1}}{3} =V_{2}$

You will found that

$V_{1} =V_{2}$

The surface tension of water is 7.28 ✕ 10−2 J/m2 at 20°C. Predict whether the surface tension of octane would be higher or lower

qaws [65]

Explanation:

It is known that octane is a hydrocarbon and London dispersion forces are the main intermolecular forces which are present in it.

Whereas water molecules tend to form hydrogen bonding forces which are actually much stronger than dipole-dipole interactions. This means that more energy is necessary to separate water molecules from one another than to separate octane molecules from one another.

Hence, we can conclude that surface tension of octane is expected to be lower than that of water when the two are considered at the same temperature.

A camcorder has a power rating of 17 watts. If the output voltage from its battery is 5 volts, what current does it use?

shtirl [24]

power = (voltage) x (current)

17 w = (5 v) x (current)

current = (17 w) / (5 v) = 3.4 Amperes
