He will be a pilot and he will fly the plane over bridges fewwww
It tells the temperature of something or someone
Answer:
527 Hz
Solution:
As per the question:
Beat frequency of the player,
Frequency of the tuning fork, f = 523 Hz
Now,
The initial frequency can be calculated as:
when
when
But we know that as the length of the flute increases the frequency decreases
Hence, the initial frequency must be 527 Hz
Crust
Explanation:
The crust is the layer of the earth with the least dense materials. The crust is made up of silicate materials.
- During the early stage in the formation of earth.
- The earth differentiated minerals based on their densities.
- Lighter minerals stayed afloat while the denser ones sank to the core of the earth.
- The core is made up of the most dense metallic minerals.
- As we go deep into the earth density increases.
- Density of crust ranges from 2.-3.3g/cm³
- The core is about 13.8g/cm³ dense.

Let u = the vertical launch speed.
Neglect air resistance, and g = 9.8 m/s².
At the maximum height of h = 120 cm = 1.2 m, the vertical velocity is zero.
Therefore
(u m/s)² - 2*(9.8 m/s²)*(1.2 m) = 0
u² = 23.52 (m/s)²
u = 4.85 m/s
The time to attain maximum height is one half of the travel time.
If t = time to attain maximum height, then
u - gt = 0
4.85 - 9.8t = 0
t = 4.85/9.8 = 0.495 s
Therefore the travel time is 2*0.0495 = 0.99 s
Answers:
(a) 4.85 m/s
(b) 0.99 s
