Answer:
vertical distance, s = 0.16 meters
Explanation:
It is given that,
An amateur player is about to throw a dart with an initial velocity of 15 meters/second onto a dartboard.
Dashboard is placed at a distance of 2.7 meters.
Calculating time from velocity and distance i.e. 
Using second equation of motion for finding vertical distance :
Here, u = 0 (for vertical velocity )
s = 0.162 meters
or s = 0.16 meters
Hence, the vertical distance by which the player will miss the target if he throws the dart horizontally, in line with the dartboard is 0.16 meters.
Answer:
Convection is heat transfer through the movement of liquids and gases.
The question is: A tuning fork vibrates at 140 [Hz] and the wave emitted by it propagates with a speed of 340 m / s. Considering the above, it can be correctly stated that the wavelength of the wave emitted by the tuning fork is
Answer: Wavelength of the wave emitted by the tuning fork is 2.43 m.
Explanation:
Given: Frequency = 140 Hz
Speed = 340 m/s
wavelength = ?
Formula used to calculate the wavelength is as follows.
where,
= wavelength
v = speed
f = frequency
Substitute the values into above formula.
Thus, we can conclude that wavelength of the wave emitted by the tuning fork is 2.43 m.
Ear Canal.
Explanation:
Sound waves enter the auricle and travel through a narrow passageway called the ear canal, which leads to the eardrum.
The featured character is the character who dives into water and brings up a small amount of mud or sand.
