A product is something sold by an enterprise to its consumers or customers. Product development is the set of activities beginning with the perception of a market opportunity and ending in the production, sale, and delivery of a product. The characteristics of a successful product development includes;
-product quality
-product cost
-development cost
-development time and
-development capability
Answer: Photoelectric wave
Explanation: Because it represents an interaction between light and matter that describes light as an electromagnetic wave.
Answer:
The acceleration is
Explanation:
From the question we are told that
The angle which the inclined plane make with horizontal is
The frictional coefficients are and
The force acting on the crate is mathematically represented as
Here f is the net force at which the crate is sliding down the plane which is mathematically represented as
is the force due to weight which is mathematically represented as
and the force due to friction which is mathematically represented as
So
substituting values
You have a point on a rectangular graph with coordinates (6, 8).
You want to describe the same location in polar coordinates ... R and Θ .
-- 'R' is the distance from the origin to the point.
-- 'Θ' is the angle you'd need to turn the x-axis counterclockwise
around the origin to make it pass through the point.
To change rectangular coordinates to polar coordinates:
R = √(x² + y²)
Θ = the angle whose tangent is (y / x) .
(6i + 8j) is the [Cartesian] vector that takes you from the origin to (6, 8) .
R = √(6² + 8²) = √(36 + 64) = √100 = 10
Θ = tan⁻¹ (8/6) = 53.13° (rounded)
In polar coordinates, the same point is 10 ∠53.13° .
Answer:
The current density is
The drift velocity is
Explanation:
From the question we are told that
The nominal diameter of the wire is
The current carried by the wire is
The power rating of the lamp is
The density of electron is
The current density is mathematically represented as
Where A is the area which is mathematically evaluated as
Substituting values
So
The drift velocity is mathematically represented as
Where e is the charge on one electron which has a value
So
