We are given the mass of an <span>aluminum sculpture which is 145 kg and a horizontal force equal to 668 Newtons. The coefficient of friction can be determined by dividing the horizontal force by the weight of the object. In this case, 668 N / 145 * 9.8 equal to coeff of friction of 0.47</span>
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:
Electromagnetic radiation
Answer:
No
Explanation:
Because the people put in charge of defining SI units said so
Answer:
- Cool, dense air begins to sink downward.
- A high-pressure system forms.
- Pressure differences cause wind to blow outward.
- The skies clear, making way for pleasant weather.
Explanation:
The air near the land warms up and rises. Cool dense air sinks being heavier. This creates a pressure difference. A high pressure system forms. This difference leads to blowing of wind from High pressure to low pressure area. Eventually sky gets clear and we experience pleasant weather. Hence, the correct order to describe this is:
- Cool, dense air begins to sink downward.
- A high-pressure system forms.
- Pressure differences cause wind to blow outward.
- The skies clear, making way for pleasant weather.
