Answer:

The Correct Answer is C

Gamma Telescope

Explanation:

  • Gamma-ray telescopes are installed at hilly altitudes like the X-ray telescope to get the best result.
  • This is also because the Gamma-ray Telescope rays sometimes get weaker when they enter to earth's atmosphere.
  • Gamma-ray telescope detects gamma rays bursts.
  • This telescope also help the astronomers to conduct mission in outer space like supernova etc.

A 15-kg block at rest on a horizontal frictionless surface is attached to a very light ideal spring of force constant 450 N/m. T
den301095 [7]

Answer:

0.266 m

Explanation:

Assuming the lump of patty is 3 Kg then applying the principal of conservation of linear momentum,

P= mv where p is momentum, m is mass and v is the speed of an object. In this case

m_pv_p=v_c(m_p+m_b) where sunscripts p and b represent putty and block respectively, c is common velocity.

Substituting the given values then

3*8=v(15+3)

V=24/18=1.33 m/s

The resultant kinetic energy is transferred to spring hence we apply the law of conservation of energy

0.5(m_p+m_b)v_c^{2}=0.5kx^{2} where k is spring constant and x is the compression of spring. Substituting the given values then

(3+15)*1.33^{2}=450*x^{2}\\x\approx 0.266 m
