For a wave:
v = fλ
v is the velocity, f is the frequency, and λ is the wavelength.
Assuming the velocity of the wave doesn't change...
If you increase its frequency, its wavelength will shorten.
The resistance of the thermometer at room temperature is 15.04 ohms.

<h3>What is a resistance thermometer?</h3>
A resistance thermometer is a type of thermometer that measures temperature through a change in resistance.
To calculate the resistance of the thermometer at room temperature, we use the formula below.
Formula:
- 100/27 = 2/(x-14.5)..............Eqquation 1
Where:
- x = Resistance of the thermometer at room temperature
Make x the subject of the equation
- x = [(27×2)/100]+14.5
- x = (54/100)+14.5
- x = 0.54+14.5
- x = 15.04 ohms.
Hence, The resistance of the thermometer at room temperature is 15.04 ohms.

The sun’s gravitational attraction and the planet’s inertia keeps planets moving is circular orbits.
Explanation:
The planets in the Solar System move around the Sun in a circular orbit. This motion can be explained as a combination of two effects:
1) The gravitational attraction of the Sun. The Sun exerts a force of gravitational attraction on every planet. This force is directed towards the Sun, and its magnitude is

where
G is the gravitational constant
M is the mass of the Sun
m is the mass of the planet
r is the distance between the Sun and the planet
This force acts as centripetal force, continuously "pulling" the planet towards the centre of its circular orbit.
2) The inertia of the planet. In fact, according to Newton's first law, an object in motion at constant velocity will continue moving at its velocity, unless acted upon an external unbalanced force. Therefore, the planet tends to continue its motion in a straight line (tangential to the circular orbit), however it turns in a circle due to the presence of the gravitational attraction of the Sun.

The Electromagnetic ave that is about the size of humans is : A typical micro waves have around 14 inches ( 1.1 meter) in height.
This is very similar to the height of human right before we hit puberty (around 9 - 10 years old)
