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)

<em>Celsius = 29.78°C</em>

Kelvin = Celsius + 273.15

Kelvin = 29.78 + 273.15

<em>Kelvin = 302.93K </em>

Two wheels with fixed hubs, each having a mass of 1kg , start from rest, and forces are applied: F1= 1 N to the first wheel and

irina [24]

Answer:

2N

Explanation:

$m = m_1 = m_2 = 1 kg$

The torques generated by tangential forces on the 2 wheels are

$T_1 = F_1R_1 = 1*0.5 = 0.5 Nm$

$T_2 = F_2R_2 = F_2*1 = F_2 Nm$

According to Newton's 2nd law, the angular accelerations generated by these torque would be

$\alpha_1 = \frac{T_1}{I_1} = \frac{0.5}{mR_1^2} = \frac{0.5}{1*0.5^2} = 2 rad/s^2$

$\alpha_2 = \frac{T_2}{I_2} = \frac{F_2}{mR_2^2} = \frac{F_2}{1*1^2} = F_2 rad/s^2$

For the 2nd wheel to have the same angular acceleration, its force must be

$\alpha_1 = \alpha_2$

$2 = F_2$

$F_2 = 2N$
