Answer:
The minimum coefficient of friction is 0.544
Solution:
As per the question:
Radius of the curve, R = 48 m
Speed of the car, v = 16 m/s
To calculate the minimum coefficient of static friction:
The centrifugal force on the box is in the outward direction and is given by:
where
= coefficient of static friction
The net force on the box is zero, since, the box is stationary and is given by:
The ability for CO2 to warm the surface of a planet through the absorption of infrared radiation is well known. What is much less appreciated, however, is just how effective of a gas it is in maintaining the greenhouse framework that helps to characterize the modern climate.
1) electrons
2) negative
3) negative
4) charge cannot be created or destroyed, just transferred
5)
6) does not allow electrons to move through it
7)plastic
8)conduct the lightning away from the house
9) electrical current
I hope this helps! I know about each of those laws for number 5, however the question didn't give a good description of any of the laws.
Best wishes!
Answer:
The center of mass changes
Explanation:
The higher the center of mass the more likely things are to topple over but the lower it is the more likely to stay put when all 4 wheels are down .
Answer:
The phenomenon of diffraction.
Explanation:
Diffraction of light that resembles the behavior of waves in water made scientists think that light have a wave nature.
