Answer:
0.28899 m
Explanation:
v = Velocity = 69 m/s
= Angular velocity = 
r = Radius of the motion
In rotational motion velocity is given by
The length of the rotation string is 0.28899 m
Answer:
1) f = 38.63 Hz
, 2) f = 115.9 Hz
Explanation:
The elephant's trunk can be approximated by a tube with a closed end, in pipes the closed ends correspond to nodes and the open ends to antinodes or bellies.
The expression for the wavelengths of this system is
4L = n λ
n = 1, 3, 5, 7 ...
also let's use the relationship between frequency and wavelength and wave speed
v = λ f
f = v / λ
f = v n / 4L
f = v / 4L n
1) the fundamental frequency occurs for n = 1
f = 340/4 2.2 1
f = 38.63 Hz
2) The first harmonic
n = 3
f = 340/4 2.2 3
f = 115.9 Hz
Answer:
True
Explanation: A professional assessment is the only way to determine the health related fitness. These could include blood work, breathing exercises, ect to make sure the person is able to perform the fitness exercises without compromising their health.
The part of the electromagnetic spectrum closest to radio waves is <u> microwaves</u>.
The wavelength of radio waves ranges from 10 cm to more than 1 km. The part of the electromagnetic spectrum that occurs closest to the radio waves is called the microwave region.
Microwaves have wavelengths ranging from around 1 mm to 10 cm.
The waves overlap in the region of 10 cm.
Thus, the region of electromagnetic spectrum closest to radiowaves is <u> microwaves.</u>
Answer:
Explanation:
Net work done on the box = increase in kinetic energy
= 1 / 2 x 10 ( 5² - 3² )
= 80 J .
