Answer:

<h3>2.3125m/s²</h3>

Explanation:

Using the equation of motion v² = u²+2aS

v is the final velocity = 120km/hr

120km/hr = 120 * 1000/1 * 3600 = 33.3m/s

u is the initial velocity = 0m/s

a is the acceleration

S is the distance covered = 240m

On substituting the given parameters

33.3² = 0²+2a(240)

33.3² = 480a

1110 = 480a

a = 1110/480

a = 2.3125m/s²

Hence the minimum constant acceleration that the aircraft require to be airborne after a takeoff run of 240 m is 2.3125m/s²

Place the types of radiation in order of INCREASING mass.
lubasha [3.4K]

Answer & explanation:

  • Gamma Radiation (γ):  Also called gamma rays. Gamma radiation is made of electromagnetic waves, has zero charge and mass, continuously emits heat and has the ability to ionize air and make it conductive of electric current.
  • Beta radiation (β): Beta rays or beta particles, are electrons, negative particles with charge - 1 and mass number 0.
  • Alpha radiation (α): Also called alpha particles or alpha rays, are particles charged by two protons and two neutrons.  They have positive charge +2 and mass number 4.
