B.f. skinner is the founder of operant conditioning .
Answer:
0.7707
Explanation:
From Snell's law,
n(1) * sin θ1 = n(2) * sinθ2
Where n(1) = refractive index of air = 1.0003
θ1 = angle of incidence
n(2) = refractive index of second substance
θ2 = angle of refraction
The angle of reflection through the unknown substance is the same as the angle of incidence of air. Thus this means that θ1 = 29°
=> 1.0003 * sin29 = n(2) * sin39
n(2) = (1.0003 * sin29) / sin39
n(2) = 0.7707
Explanation:
product of force and perpendicular distance
Answer:
The velocity of the car after 3 seconds is 5.5 m/s
Explanation:
Mathematically, we can get the acceleration of the car first;
F = m•a
where m is the mass, F is the applied force and a is the acceleration
from the question;
F = 1500 N , m = 4500 kg and a = ?
By rewriting the formula;
a = F/m
a = 1500/4500 = 1/3 m/s^2
Now to get the velocity of the car after 3 seconds;
Mathematically;
V = U + at
where V is the final
velocity, U is the initial velocity,
From the question, we are trying to get V;
where U = 4.5 m/s
a = 1/3 m/s^2 and t = 3 seconds
Thus;
V = 4.5 + (1/3)(3)
V = 4.5 + 1
V = 5.5 m/s
