Two trucks with equal mass are attracted to each other with a gravitational force of 5.3 x 10 -4 N. The trucks are separated by

HACTEHA [7]

Answer:

7327 kg or 7.3 tons

Explanation:

We have Newton formula for attraction force between 2 objects with mass and a distance between them:

$F_G = G\frac{M_1M_2}{R^2}$

where $G =6.67408*10^{-11} m^3/kgs^2$ is the gravitational constant on Earth. $M = M_1 = M_2$ is the masses of the 2 objects. and R = 2.6m is the distance between them.

$F_G = 5.3*10^{-4}N$ is the attraction force.

$5.3*10^{-4} = 6.67408*10^{-11}\frac{M^2}{2.6^2}$

$7941265 = \frac{M^2}{2.6^2}$

$M^2 = 53682948.76$

$M = \sqrt{53682948.76} \approx 7327 kg$ or 7.3 tons

A 2.3 kg , 20-cm-diameter turntable rotates at 110 rpm on frictionless bearings. Two 460 g blocks fall from above, hit the turnt

boyakko [2]

Answer:

The correct solution is "64 RPM".

Explanation:

The given values are:

Mass,

M = 2.3 kg

Diameter,

D = 20 cm

i.e.,

= 0.2 m

Rotates at,

N = 110 rpm

Mass of block,

m = 460 g

i.e.,

= 0.46 kg

According to angular momentum's conservation,

⇒ $I_1\omega_1=I_2\omega_2$

then,

⇒ $I_1=\frac{1}{2}MR_2$

On substituting the values, we get

⇒ $=\frac{1}{2}\times 2.3\times (0.1)^2$

⇒ $=\frac{1}{2}\times 0.023$

⇒ $=0.0115 \ kg \ m^2$

Now,

⇒ $I_2=I_1+2mR^2$

$=0.0115+2\times 0.46\times (0.1)^2$

$=0.0115+0.0092$

$=0.02 \ kg \ m^2$

then,

⇒ $0.0115\times 110=0.02\omega_2$

⇒ $1.265=0.02\omega_2$

⇒ $\omega_2=\frac{1.265}{0.02}$

⇒ $=63.25 \ or \ 64 \ RPM$
