Gallium is a solid metal at room temperature, but it will melt to a liquid in your hand. the melting point of gallium is 85.6 f.

Nimfa-mama [501]

Fahrenheit = 85.6°F

Celsius = (5/9) (Fahrenheit - 32)

Celsius = (5/9) (85.6 - 32)

Celsius = (5/9) (53.6)

Celsius = 29.78°C

Kelvin = Celsius + 273.15

Kelvin = 29.78 + 273.15

Kelvin = 302.93K

A stagehand starts sliding a large piece of stage scenery originally at rest by pulling it horizontally with a force of 176 N. W

Diano4ka-milaya [45]

Answer:

Option (a)

Explanation :

A stage hand starts sliding a large piece of stage scenery originally at rest by pulling it horizontally with a force of 176 N.

Hence Force applied $\text { Fapplied }=176 \mathrm{N}$

Force on piece of scenery $\mathrm{F}_{\mathrm{g}}=490 \mathrm{N}$

$\Sigma \mathrm{F} \mathrm{y}=\mathrm{F} \mathrm{n}-\mathrm{Fg}=0$

$\mathrm{Fn}=\mathrm{Fg}$

$\mathrm{FS}_{\mathrm{max}}=\mathrm{F}_{\mathrm{applied}}$

µk = $\frac{\mathrm{Fs} \max }{\mathrm{Fn}}$

= $\frac{\text { Fapplied }}{\mathrm{Fg}}$

= $\frac{176}{490}$ =0.36

coefficient of static friction is 0.36
