Given that,
Force F= 30,000 N
mass m= 4000 kg
acceleration =?
as F= ma
a= F/m
a= 30,000/4000
a= 7.5 m/s²
The acceleration of the aeroplane will, therefore, be 7.5 m/s².
Answer:
The required force to stretch the steel guitar string by 0.500 mm is 10.1 N
Explanation:
The steel guitar string diameter is 0.300 mm and its length measures 70.0 cm. To calculate the force required for the specified elongation using Young's modulus, one would apply the relevant formulas, yielding 10.1 N.
The fundamental relationship between frequency and wavelength for light (as an electromagnetic wave) can be summarized as: f = c/λ, where c is the speed of light, f represents the frequency, and λ signifies the wavelength of the wave. By applying this formula, we can derive the frequency value.
Answer:
Option A is the correct choice.
Inheritance, superclass, subclass
A new class of objects can be easily established through **inheritance**; the new class (termed the **superclass**) inherits the attributes of an existing class (referred to as the **subclass**), and can also modify them while including its own distinct features.
Explanation:
In object-oriented programming, a class is a concept that describes extensible program code utilized to define, name, and implement the desired functions of objects.
Inheritance refers to the formation of new classes derived from pre-existing ones. The core properties of the original classes are retained in the new classes formed from them.
Thus, new classes (generally enhancements of the original classes since they encompass the desirable attributes of the originals plus additional favorable traits or amendments) are identified as superclasses, while the older, pre-existing classes are classified as subclasses.
