Jovian planets are also known as gas giants and are the four outer planets Jupiter, Saturn, Uranus and Neptune. Uranus stands out from this group because of the tilt of its axis. Uranus is tilted on its side. Scientists speculate that this tilt may be as a result of a collision with a large body just after the planet was formed. Uranus is tilted 98 degrees compared to earth's 23 degrees.
Answer: Yes it is possible to turn a vector to a scalar.
Explanation:
Vectors and scalars represent different types of physical quantities. However, it is sometimes necessary for them to interact. Adding a scalar to a vector is impossible because of their different dimensions in space. Although It is possible to multiply a vector by a scalar.
The terminal velocity as it falls through still air is 4.65154 in/s.
The diameter of small water droplet is 1.25 mil= 1.25×0.0254×10^-3 m
= 3.175 × 10^-5 m
Now the viscosity of still air is η = 1.83× 10⁻⁵ Pa
So the formula for drag force is:
Fd = 6πηrv
where, v is the velocity.
Now to attain terminal velocity acceleration must be zero.
→ W = Fd
ρVg = 6πrηv
ρ × 4/3 πr³×g = 6πrηv
v = 2/9 × ρgr³/ η
v = 2/9 × 10³×9.81×(3.175×10^-3) / 18.6×10^-6
v = 0.1181 m/s
v = 4.65154 in/s

The wavelength of radiowaves is 3.042 m.
<h3>What is radiowaves?</h3>
The electromagnetic spectrum's longest wavelengths, which are found in radio waves, are normally found at frequencies of 300 gigahertz and below.
Frequency given, f = 98.6 MHz = 98.6 x
cycles/second
Electromagnetic waves including radiowaves also travel at the speed of light.
Therefore, c = 3.0 x
m/sec
Wavelength = speed/frequency
wavelength of 98.6 MHz = 3.0 x
