Answer:
75 m/s
Explanation:
We can apply motion equations here
V = U + a * t
V = velocity @ t time
U = initial velocity
a = acceleration
t = time taken
V = U + a * t
V = 0+ 3 * 25
V = 75 m/s
After 25 seconds , subjected to the given acceleration velocity is increased from 0 to 75 m/s
Answer:
0.00278 km/sec2 or 36,000 km/hr2 .
Explanation:
Answer:resultant vector R = (0, 3)
Explanation: vector A = (3, 0)
vector B =(-3, 3)
Vectors are added such that those in same directions are added together. The resultant vector R is the given by R = (3-3, 0+3)
= (0, 3)
The answer you are looking for is A
Answer:
Light's angle of refraction = 37.1° (Approx.)
Explanation:
Given:
Index of refraction = 1.02
Base of refraction = 1
Angle of incidence = 38°
Find:
Light's angle of refraction
Computation:
Using Snell's law;
Sin[Angle of incidence] / Sin[Light's angle of refraction] = Index of refraction / Base of refraction
Sin38 / Light's angle of refraction = 1.02 / 1
Sin[Light's angle of refraction] = Sin 38 / 1.02
Sin[Light's angle of refraction] = [0.6156] / 1.02
Sin[Light's angle of refraction] = 0.6035
Light's angle of refraction = 37.1° (Approx.)
