Answer:
The frequency of sound wave created by trumpet is 437.5Hz
Explanation:
Given
the speed of sound wave = 350 m
the wavelength of sound wave = 0.8 m
the frequency of sound wave = ?
All the waves have same relationship among wavelength, frequency and speed, which is given by the equation:
v = fλ, where
v is speed of the wave
f is frequency of the wave
λ is wavelength of the wave
therefore frequency of sound wave is given by
f = v/λ
= 350m/0.8m
= 437.5
= 437.5Hz (since 1 = 1 Hz (Hertz)
Hence the frequency of sound wave created by trumpet is 437.5Hz

The image is real and larger than the object.
Answers
Answer:
The image is virtual and smaller than the object.
Explanation:
A concave lens is a diverging lens, meaning that it spreads out light rays that have been refracted through it. A concave lens is thinner at its center than at its edges.
It always produces virtual images because the image appears to form on the same side of the lens where the object is placed.
The image is always smaller than the object. Far the object, smaller will be its image.
A light ray diagram of a concave lens is attached for a better understanding.

No, the water is identical, but because we know that c/5 = f-32/9, where c is Celsius and f is Fahrenheit, the thermometer scales differ. (This is how they are linked.)
What is Fahrenheit and Celsius?
The difference between Celsius and Fahrenheit is 1.8. In other words, 1 degree Fahrenheit is equivalent to 5/9 degree Celsius. Despite having rather significant variances, these two temperature scales collide at -40 degrees,
The Celsius scale, sometimes known as the centigrade scale, is a scale of temperature that is based on the freezing point of water at 0°C and the boiling point of water at 100°C. As a result, 100/5=212-32/9, which equals 20=180/9. The Fahrenheit temperaturescale is based on the fact that water freezes at 32°F and boils at 212°F.
