It's called the 'Electrostatic Force'.
It's proportional to the product of their charges, and
inversely proportional to the square of the distance
between them.
It pulls them together if their charges are opposite.
It pushes them apart if they have the same charge.
Im not sure about this one but the one i will go for is a.
Answer:
The average acceleration of the rocket, a = 8.5 m/s²
Explanation:
Given that,
The upward force of the rocket, F = 1700 N
The time duration of rocket exerted the force, t = 8 s
The mass of the rocket, m = 200 Kg
The force exerted by the rocket is equal to the product of its mass and acceleration.
Therefore, the formula for force
<em> F = m x a</em>
a = F / m
Substituting the given values in the above equation
a = 1700 N / 200 Kg
= 8.5 m/s²
Hence, the acceleration of the rocket is, a = 8.5 m/s²
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>
