N = normal force by the surface of incline on the box resting on it
m = mass of the box resting on the incline surface = 30 kg
g = acceleration due to gravity acting on the box = 9.8 m/s²
θ = angle of the incline with the horizontal surface = 15⁰
from the force diagram , force equation perpendicular to incline surface is given as
N = m g Cosθ
inserting the values in the above equation
N = (30 kg) (9.8 m/s²) Cos15
N = 284 newton
Answer:
Hi,
It states that the in linear systems, two or more stimuli cause a net stimulus that is equal to the sum of the individual responses. Applying the principle of superposition to waves, two waves of the same magnitude at a point in space add up to form a resultant displacement at that point which equals the sum of the two vectors.
Explanation
When two or more waves meet, they can interact to form a bigger wave or cancel out. In both cases, the resultant effect is caused by a combination of the two. This principle is applied in noise cancelling headphones that capture and cancel the noise around you by playing an opposite sound that ensures the cancelling of the destructive noise.
Best wishes!
Answer: third option: <span>have a full outer electron shell.
Explanation:
Noble gases is the family name given to the elements of group 18 of the periodic table.
The electron valence shell of all these elements is full:
He has two electrons wich is the maximum an atom of the first row can have.
Ne, Ar, Kr, Xe, and Rn (well you can include Og which is the last noble gas discovered; it is the element number 118), have 8 electrons on their valence electron shell, which is the maximum any element can have.
Precisely, that feature (valence shell full) accounts for the low reactivity of these elements, which conferred them the title of nobles (they hardly combine with other elements to form compounds).

Answer:The trail mix is a heterogeneous mixture.
Explanation: Heterogeneous mixture is a mixture of the same phase like sugar dissolved in water.
Trail mix involved physical objects, thus it is a mixture of peanuts, small fruits etc.
