The coefficient of static friction is 0.234.
Answer:
Explanation:
Frictional force is equal to the product of coefficient of friction and normal force acting on any object.
So here the mass of the object is given as 2 kg, so the normal force will be acting under the influence of acceleration due to gravity.
Normal force = mass * acceleration due to gravity
Normal force = 2 * 9.8 = 19.6 N.
And the frictional force is given as 4.6 N, then
Coefficient of static friction = 4.6 N / 19.6 N = 0.234
So the coefficient of static friction is 0.234.
Answer:
The spacing between the slits is 
Explanation:
From the question we are told that
The wavelength of the light is 
The distance of the slit from the screen is 
The number of bright fringe is 
The length the fringes span is 
The fringe width (i.e the distance of between two successive bright or dark fringe) is mathematically represented as
Where d is the distance between the slits
is the fringe width which can also be evaluated as
Substituting values
Making d the subject of formula in the above equation
Substituting values
Answer:
100
Explanation:
by dividing 2000N and 1000kg.

Answer:
In wind turbines, the blades rotate due to the wind.
Explanation:
In wind turbines, the blades rotate due to the wind.<u> While the blade rotates the generator connected to it also rotates.</u> Thus the <u>kinetic energy from the wind initiates the electric generator which in turn produces the electricity.</u>
Thus the<u> kinetic energy of the wind is converted to electricity.</u>

Hope this helps!
Have a Wonderful Friday!

Answer:
The two types of forces are related; a moving magnet can make electrical charges move, cause an electric current, and in turn cause magnetism. ... Objects that have the same charge, both positive or both negative, repel each other, and those with opposite charges attract each other.
