Katarina [22]

Answer:v=41.23 m/s

Explanation:

Given

mass of heavy object m_1=52 kg

distance of m_1 from the axle r_1=14 cm

mass of rock m_2=123 gm

Length of rod =4.1 m

distance of m_2 from axle r_2=4.1-0.14=3.96 m

Net torque acting is

T_{net}=m_1gr_1-m_2gr_2

T_{net}=52\times 0.14\times g-0.123\times 3.96\times g

T_{net}=6.793\times 9.8

T_{net}=66.57 N-m

Work done by T_{net} is converted to rock kinetic Energy

thus

T_{net}\times \theta =\frac{mv^2}{2}

Where \theta =angle\ turned =\frac{\pi }{2}

v= velocity\ at\ launch

66.57\times \frac{\pi }{2}=\frac{0.123\times v^2}{2}

v^2=66.57\times \pi

v=\sqrt{1700.511}

v=41.23 m/s

Why does the solar system consist of small planets orbiting close to sun and larger on more distant
ahrayia [7]

Answer:

The inner planets are smaller and rockier

Explanation:

Astronomers divide the planets into two groups in Solar system,  the  inner planets and outer planets. The inner planets are smaller and rockier and it is closer to the sun.  The outer planets are larger , further far away and made of gas

The inner planets are Mercury, Venus , Earth and Mars.  The outer planets Jupiter , Saturn , Uranus and Neptune comes after an  asteroid belt. In some other planetary systems the gas are close to the sun.

particles in a disk of gas and dust will form Planets.  If they orbit the star they are colliding and sticking.  The stars wind blows away their gases . So the nearest planets to starts are rockier.
