Answer:
5.3×10⁴ m/s
Explanation:
From the question,
Momentum = mass× velocity
M = mV................ Equation 1
Where M = momentum of the airplane, m = mass of the airplane, V = Velocity of the airplane
make V the subject of the equation
V = M/m.................. Equation 2
Given: M = 1.6×10⁹ Kg.m/s, m = 3.0×10⁴ kg
Substitute these values into equation 2
V = 1.6×10⁹/3.0×10⁴
V = 5.3×10⁴ m/s
In the first case, the momentum is 4,860,000Kgm/s while in the second case, the momentum is 4,550,000Kgm/s.
<h3>What is momentum?</h3>
The term momentum of a body refers to the product of mass and velocity. It is a vector quantity.
In the first case;
momentum = 81,000Kg * 60m/s = 4,860,000Kgm/s
In the second case, we must find the resultant velocity V
V = √(25)^2 + (43)^2
V = 50 m/s
Hence;
Momentum = 91000Kg * 50 m/s
= 4,550,000Kgm/s

Answer:
the wavelength of the first instrument is approximately 1.5 greater than that produced by the second instrument.
Explanation:
Given:
f₁ = frequency = 266 Hz
f₂ = 400 Hz
Question: How do the wavelength of each of these sound waves compare, λ₁ = ?, λ₂ = ?
The equation to solve this question is
Here
λ = wavelength of the sound
v = speed of sound = 340 m/s
f = frequency of each instrument
You need to calculate both wavelengths
According to the results, the wavelength of the first instrument is approximately 1.5 greater than that produced by the second instrument.
The answer is B. StructuralismThis school believes that the mind is divided into three basic elements, namely: sensations, feelings and images. This idea allows psychologist to study the interaction between the elements in order to create a conscious experienced. This will allow the person to associate the elements to one another and thus create a perception
