Answer:isotopes
Explanation:Isotopes form when the number of neutrons and atomic number change except for the protons don't change
No, you are at a constant rate which means that you are always at 40mph
Momentum of the wagon increases by (200 x 3)
= 600 newton-sec
= 600 kg-m/sec
Given data:
refractive index of glass (n₁) = 1.50 ,
refractive index of air (n₂) = 1.00,
determine the critical angle of the glass (θₙ) = ?
Critical angle is defined as "it is the incidence angle, beyond which total internal reflection will occurs".
According to snell's law critical angle is given by the equation
<em>Assume light travels from higher refractive index (glass) to lower refractive index (air)</em>
<em>Critical angle, </em>
<em> sin θc = (n₂/n₁) n₁ > n₂</em>
<em> </em>θc = sin ⁻¹(1.00/1.50)
θc = 41.8⁰
<em>The critical angle of the glass is 41.8⁰</em>
