We know average speed =total distance/time taken
So avg speed=(85+63)/(5+5)=14.8km/hr
Answer:
If the height of the ramp is changed at a different height then the speed of the car will change.
Answer:
I'm pretty sure your speed relative to the ground would be 110 meters per second. However that is just a guess and I'm not 100% sure.
Answer:
Explanation:
The critical angle in oil for the oil-water interface refers to the angle for which the light ray is totally reflected.
Angle of incidence = 73.4°
Angle of refraction = 1.470°
Index of refraction = 1.333
Here, refers to the critical angle.
is an index of refraction
is angle of refraction
Here, angle of incidence is more than the critical angle,
light undergoes total internal reflection.
Answer:
5,126 N*m
Explanation:
Since the magnitudes are vectors, the Pythagoras theorem can be used to find the resulting vector ((1,8^2 + 4,8^2)^1/2). The direction of this vector will be contained in the X-Y plane, specifically in the fourth quadrant in Cartesian coordinates.
