Newton's second law of motion can be formally stated as follows: The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object.
Density = mass / volume D=m/v
Mass= 12.6 g
Volume=(4.1 cm)³ = 4.1 cm x 4.1 cm x 4.1 cm = 68.921 cm³
Density =12.6 g / 68.921 cm³ = 0.1828 g/cm³
Answer:
A. change in acceleration or direction
Explanation:
A motion map can be defined as the graphical representation of the acceleration, velocity and position of a body or an object at specific intervals (period of time) or time readings.
For motion maps that illustrate accelerated motion, a new level indicates a change in acceleration or direction.
Acceleration can be defined as the rate of change of the velocity of an object with respect to time.
This simply means that, acceleration is given by the subtraction of initial velocity from the final velocity all over time. Hence, if we subtract the initial velocity from the final velocity and divide that by the time, we can calculate an object’s acceleration.
Mathematically, acceleration is given by the equation;
Additionally, acceleration is a vector quantity because it has both magnitude and direction.
Given: Wavelength λ = 410 nm convert to Meters m = 4.10 x 10⁻⁷ m
Speed of light c = 3 x 10⁸ m/s
Required: Frequency f = ?
Formula: c = λf
f = c/λ
f = 3 x 10⁸ m/s/4.10 x 10⁻⁷ m
f = 7.32 x 10¹⁴/s or 732 Thz (Terahertz)
