A 100 hz sound wave is traveling through the air. if we increase the frequency to 200 hz, this will _____ the wavelength. a 100
1 answer:
The correct answer is "decrease":
<span>A 100 hz sound wave is traveling through the air. if we increase the frequency to 200 hz, this will INCREASE the wavelength.
Let's see why. The basic relationship between frequency and wavelength of a wave is
</span>
<span>where
v is the speed of the wave
f its frequency
</span>
its wavelength
<span>
We can see from this equation that, if the frequency is increased, if the speed of the wave does not change (and this is the case), then the wavelength of the wave must decrease, since the ratio </span>
becomes smaller.

Answer:
a = 1600 m / s²
Explanation:
For this exercise we use the kinematics relations,
v² = v₀² + 2 a x
where v₀ is the initial velocity of the bullet, which as part of rest is zero, for the distance (x) we can assume that the gases accelerate along the entire trajectory of the cannon x = 2m
a =
let's calculate
a =
a = 1600 m / s²
The required energy to accelerate the golf ball is .
- Energy, which is observable in the execution of labor as well as in the form of light and heat, is the quantitative quality that is transmitted to an object or to a physical phenomenon in physics.
- Energy is a preserved resource; according to the rule of conservation of energy, energy can only be transformed from one form to another and cannot be created or destroyed.
- The joule, which is defined as "the energy transmitted to an object by the effort of moving it a length of one metre against a force of one newton," is the standard measure for power in the International System of Units (SI).
