The individual inherited 23 chromosomes from each parent.
Given parameters:
Frequency of the wave = 1520kHz = 1520 x 10³Hz
Unknown:
Wavelength of the radio photon = ?
Energy of the wave = ?
Solution:
The wavelength of any electromagnetic wave can found using the expression below;
C = f x ∧
Where C is the velocity of light = 3 x 10⁸m/s
f is the frequency of the wave
∧ is the wavelength
Since the unknown is ∧, input the known parameters and solve for it;
3 x 10⁸ = 1520 x 10³ x ∧
Wavelength =
Wavelength =
Wavelength = 1.97 x 10²m
ii. Energy of the wave;
Energy of a wave = hf
where h is the planck's constant = 6.63 x 10⁻³⁴ J Hz⁻¹
f is the frequency of the wave
Input the parameters and solve;
Energy of the wave = 6.63 x 10⁻³⁴ x 1.52 x 10⁶
= 10.1 x 10⁻²⁸J
The energy of this wave is 10.1 x 10⁻²⁸J
Answer:
Solids: Sound travels fastest through solids. This is because molecules in a solid medium are much closer together than those in a liquid or gas, allowing sound waves to travel more quickly through it. In fact, sound waves travel over 17 times faster through steel than through air
Explanation:
The average net force exerted is 36000 N.
<u>Explanation</u>:
According to Newton's 2nd law of motion,
The net force acting upon the object is the product of mass and acceleration of an object.
Force = ma
where m represents the mass,
a represents the acceleration.
Acceleration = (change in speed) / (change in time)
Acceleration = (45 m/s) / (7 sec) = (45 / 7) m/s²
Force = (5,600 kg) x (45 /7 m/s²)
Force = (800 x 45) Newtons
Force = 36000 Newtons.
Easy, it is called:
The intensity.
