Answer:

$\alpha=214.8 rad/s^2$

Explanation:

We are given that

$F_1=137 N$

$F_2=43 N$

Net force=F= $F_1-F_2=137-43=94 N$

Mass,m=1.21 kg

Radius,r=0.723 m

We have to find the magnitude of its angular acceleration.

Moment of inertia , $I=\frac{1}{2}mr^2$

Substitute the values

Torque , $\tau=I\alpha$

$F_{net}\times r=\frac{1}{2}mr^2\alpha$

$\alpha=\frac{2F_{net}}{mr}$

$\alpha=\frac{2\times 94}{1.21\times 0.723}$

$\alpha=214.8 rad/s^2$

Find the density of a substance that has a volume of 754 cm3 and a mass of 7,917 grams. Don't forget your units!

Anit [1.1K]

Answer:

$\boxed{\sf Density \ of \ the \ substance = 10.5 \ g/cm^3}$

Given:

Mass (M) = 7917 grams

Volume (V)= 754 cm³

To Find:

Density of the substance

Explanation:

$\boxed{ \bold{\sf Density \ (\rho) = \frac{Mass \: (M)}{Volume \: (V)}}}$

Substituting values of M & V in the equation:

$\sf \implies \rho = \frac{7917}{754}$

$\sf \implies \rho = 10.5 \: g/ {cm}^{3}$
