For the 5.0Kg block with the force of 15 Newton, the coefficient of static friction (μ) comes out to be 0.306. Applying the formula F = μmg.
Static friction acts on stationary body/body at rest. Let μ be the coefficient of static friction between the block and the horizontal floor.
Using the formula: F = μmg
Where,
F = Force , m= mass of the block and g = gravity.
and values of: m= 5.0Kg, F= 15.0N, g= 9.8m/s²
We can get: μ = F/(mg)
μ = 15/49
μ =0.306
Therefore, coefficient of static friction (μ) = 0.306.

Which is a substance that takes the shape and volume of its container?
liquid
Answer:
True.
Explanation:
The formula for the centripetal acceleration of an object can be calculated by the formula as follows :
Where
v is the speed of an object
r is the radius of the circle
It means, the centripetal acceleration depends directly on the square of the object's speed and inversely on the radius of the circle. Hence, the given statement is true.
Answer:
Yes.
Explanation:
-This is because the threshold voltage for the green light is much lower than that of the blue light.
-A longer wavelength in the greenlight necesitates the need for a lower voltage in the banana plug.
Dont know, fr like i dont even know
