In an inelastic collision, a steel ball of mass 200 g was hit hard into a large ball of dough of mass 700 g. The velocity of the

steel ball was 25 m/s. After the collision, the steel ball was stuck in the dough, and this combined system rolled for some time. What was the velocity of the system of the steel ball and dough after the collision?A) 5.6 m/sB) 7.5 m/sC) 8.8 m/sD) 11.1 m/s

Answer:

Velocity after collision will be 5.56 m/sec

So option (a) will be correct answer

Explanation:

Mass of steel ball m_1=200gram=0.2kg

Speed of steel ball before collision v_1=25m/sec

Mass of large ball m_2=700gram=0.7kg

Velocity of large ball v_2=0m/sec

According to conservation of momentum

m_1v_1+m_2v_2=(m_1+m_2)v

0.2\times 25+0.7\times 0=(0.7+0.2)v

v=5.56m/sec

So velocity after collision will be 5.56 m/sec

So option (a) will be correct answer

ou are out stargazing with your 13.4-cm telescope. You point your telescope at an interesting formation in the sky, which you th
Alinara [238K]

Answer:

θ = 4.716 10⁻⁶ rad

Explanation:

In order for the releases to be considered separate, they must meet the Rayleigh criterion that establishes that the maximum diffraction of one star must coincide with the first minimum of the diffraction pattern of the second star.

We use the diffraction equation for a slit

            a sin θ = m λ

The minimum occurs at m = 1

             sin θ = λ / a

Since the angles in these systems are very small, we can approximate the sine to its angle in radians

             θ = λ / a

The telescope has a circular aperture whereby polar cords should be used, which introduces a constant number

           θ = 1.22 λ / a

Let's calculate

          θ = 1.22 518 10⁻⁹ / 13.4 10⁻²

          θ = 4.716 10⁻⁶ rad

A man holds a child on his shoulders while watching a football match. How many work has he done if the game lasts for 2 hours? ​
Shalnov [3]

very interesting and amazing question u had asked but i get it...

Answer

  • work done is given by

W = Force × Displacement

  • but in above case force is exerted on the men as the weight of the child × gravitational pull of earth (9.8 m/s^2) but the displacement or movement is ZERO
  • there for W= F×0 =0
  • so even after carrying child for 2 hours work done by the men will be zero

<u>More</u><u> </u><u>examples</u>

  • a person standing straight and lifting weight
  • a person carry some weight and walk in a circular path and came back to its original position.........in this case also Displacement will be zero

------------------------------------

hope it helped u buddy
