It’s B. Sound travels faster through solids than liquids. Have you ever put your head on a desk, and tap the desk? That’s an example of it going faster through solids
Answer:
5 N
Explanation:
From the question,
The magnitude of the force that would be required to just loosen the nut when the force is applied perpendicularly at the end of the handle is
Fy = Fsinθ................. Equation 1
Where Fy = force acting perpendicular at the end of the handle, F = Force applied to the handle, θ = angle of inclination of the force to the end of the handle.
Given: F = 10 N, θ = 30°
Substitute these values into equation 1
Fy = 10(sn30°)
Fy = 10(0.5)
Fy = 5 N.
<u>Answer:</u>
Terameter is 10²⁴ times picometer.
<u>Explanation:</u>
1 Tera = 10¹², 1 Giga = 10⁹, 1 Mega = 10⁶, 1 kilo = 10³
1 Pico = 10⁻¹², 1 Nano = 10⁻⁹, 1 Micro = 10⁻⁶, 1 milli = 10⁻³
Here we need to find how much larger is a terameter than a picometer.
1 terameter = 10¹²m and 1 picometer = 10⁻¹²m
Ratio = terameter/picometer = 10¹²/10⁻¹² = 10²⁴
So terameter is 10²⁴ times picometer.
The answer to that would be that is false!
Answer:
Velocity of the wave is 1.7 m/s
Explanation:
As we know that the frequency of the wave is defined as the number of waves crossing a fixed point per second
So here we will have
Also we know that the distance between two consecutive crest or two consecutive trough is known as wavelength
So here the wavelength of the wave is given as
now we have
