The points with highest amplitudes are the antinodes. Antinodes are the points at which displacement of particle is maximum.
Hope this much clarifies your doubt.
Answer:
1.319 × 10³ m/s
Explanation:
The formula for speed of sound is ;
v= f*λ where
v= speed of sound
f= frequency of sound= 3.705 kHz = 3705 Hz
λ= wavelength of sound = 35.6 cm = 0.356 m
Applying the formula ;
v= f*λ
v= 3705 * 0.356
v=1318.98 m/s
v= 1.319 × 10³ m/s
If a football is kicked from the ground with a speed of 16.71 m/s at an angle of 49.21 degrees, then the vertical component of the initial velocity would be 12.65 m/s
<h3>What is Velocity?</h3>
The total displacement covered by any object per unit of time is known as velocity. It depends on the magnitude as well as the direction of the moving object. The unit of velocity is meter/second.
As given in the problem A football is kicked from the ground with a speed of 16.71 m/s at an angle of 49.21 degrees
The horizontal component of the velocity is given by
Vx = Vcosθ
The vertical component of the velocity is given by
Vy = Vsinθ
As we have to find the vertical component of the velocity given that speed of 16.71 m/s at an angle of 49.21 degrees from the ground
Vy = 16.71 × sin49.21°
Vy = 12.65 m/s
Thus, the vertical component of the velocity would be 12.65 m/s

Answer:
We know the information about atomic size, energy, electronic configuration etc. of atom from the periodic table.
Explanation:
- Periodic table is the arrangement of elements that are arranged according to their properties and electronic configuration.
- In periodic table, on furthest right side of the periodic table, noble gases like He, Ne, Ar etc are arranged.
- The atomic number of element increases while moving from left towards right in the periodic table.
- The metallic character of element decreases as we proceed the table towards right.
- They readily accept electron to fill the valence shell hence becoming more metallic in character.
'C' and 'D' are the same statement, and none of the 3 choices
is good.
Electrical energy is produced in a generator, a solar panel, or
a battery, not in things with resistance.
From the generator or battery, current flows through a circuit of
one or more components.
The greater the resistance of a component, the more energy is
LOST as the current flows through it. The component dissipates
the energy in the form of heat.
