Answer:
<em>Load</em>
Explanation:
<em>The load in an electric circuit is any device that converts electrical energy into another form of energy.</em>
Differentiate the expression, to obtain expression for velocity. Set velocity to 0, this when max height is reached. Obtain the tmax from that expression.
<span>h(t) = –16t² + 32t + 6
</span><span>h'(t) = –32t² + 32
0 = </span>–32t² + 32
t max= 1
hmax = <span> –16(1)² + 32(1) + 6
hmax = 22
Therefore, first option is the correct answer.</span>
Answer:
To have the same kinetic energy the speed of the marble must be 9 times the speed of rock.
Explanation:
The general formula of kinetic energy is given as follows:
where,
K.E = Kinetic Energy
m = mass of the object
v = speed of the object
So, for the marble and rock to have same kinetic energy, we can write:
<u>Hence, to have the same kinetic energy the speed of the marble must be 9 times the speed of rock.</u>
In most cases, when wave refract, frequency and amplitude will be constant while wavelength and speed will change.

PROPERTIES OF WAVES</h3>
The four properties of waves are:
When a wave moves from one medium to another, the wave will undergo refraction.
When a wave move for instance, from water to glass, the wave will refract by changing direction. In most scenario, the frequency of the wave will be constant while the wavelength of the wave will change. Since the wavelength will change, the speed will also change.
Therefore, when a wave moves from one medium to another, the properties of the wave that change are wavelength and wave speed.

Answer: Pressure fluctuations travel along the direction of propagation of the sound wave.
Explanation:
Sound wave is a type of longitudinal wave. It is defined as a wave which consist of vibrations of particles traveling through a medium( such as air, or water).
Sound wave is propagated by the alternating adiabatic compression and expansion of the medium. The COMPRESSIONS are regions of high air pressure while the RAREFACTIONS are regions of low air pressure. Therefore, Since a sound wave consists of a repeating pattern of high-pressure and low-pressure regions moving through a medium, it is sometimes referred to as a PRESSURE WAVE.
The direction of the vibrating particles is parallel to the direction of propagation and that's why it's a type of LONGITUDINAL WAVE. Therefore, the correct option that
concludes about the direction in which such pressure fluctuations travel is
(Pressure fluctuations travel along the direction of propagation of the sound wave.)
