When we are using scissors, our hand makes an open and close motion.
Explanation:
Answer:
Polarized glasses contains a special filter that block dangerous intensity of lights which are reflected by flat surfaces and they help in reducing glare and discomfort
Explanation:
Sunlight scatters in all the direction. But when this light strikes with the flat surfaces, then the light which is reflected by the flat surface tend to become polarized, means the reflected light will travel in all directions. This reflecting light creates a dangerous intense light that causes glare and reduces visibility.
Polarized glasses contains a special filter that block this type of dangerous intensity lights, help in reducing glare and discomfort.
Therefore, by the above discussion it can be say that the polarized sunglasses particularly effective in reducing glares.
The cT is short for continental tropical. It originates over the Mexican Plateau region and desert SW. It is a warm air mass over a continent. It is hot and very dry because of where it formed. Hope these facts about continental tropical air masses helped you!
Answer:
d = 493.72 m
Explanation:
Given that,
Initial velocity of the train, u = 80 km/h = 22.22 m/s
Acceleration of the train, a = -0.5 m/s² (negative as it slows down)
Finally brakes are applied, v = 0
We need to find the distance the train travels. Let the distance be d. Using third equation of kinematics to find it.
So, the required distance is equal to 493.72 m.
