Answer:
Electronmagnetic waves: yes
Mechanical waves: no
Explanation:
Electromagnetic waves consist of electric fields and magnetic fields that oscillate perpendicularly to each other, and also in a plane perpendicular to the direction of propagation of the wave (therefore they are called "transverse waves".
As all waves, electromagnetic waves transport energy (but not matter). In particular, the type of energy transferred by electromagnetic waves is in the form of radiation, also called light energy.
Conversely, mechanical waves consist of oscillations of the particles in a medium. Mechanical waves also carries energy (but not matter), but not in the form of radiation (light energy): in fact, the energy is carried as vibrations of the particles in the medium, so it is a different type of energy.
<span>You can use the equation
V_xf = V_xi + a_x(t)
V_xf = 20.0m/s
V_xi = 0m/s
ax = 2.0
t
Thus, solve for t and get 10seconds
and then take 5 seconds to break after 20 seconds of driving
so for
a) 10 + 20 + 5 = 35 seconds
</span><span>for part b)
You can use the formula
Delta x/Delta t = average velocity
Need to find xf, knowing xi = 0
Thus, use the formula
x_f = x_i + V_xi(t) + (1/2)a_x(t)^(2)
x_f = 0 + 0(10) + (1/2)(2.0)(10)^(2)
x_f = 100m
so for the first 10 seconds the truck traveled 100ms
At a speed of 20m/s
20m/s = xm/20s
20*20 = x
x = 400
thus we have 100+400 = 500m
then it slows down from 500m to x_f
thus I use the equation
x_f = x_i + (1/2)(V_xf + V_xi)t
x_f = 500 + (1/2)(0 + 20)(5)
x_f = 500 + 50
x_f = 550
therefore the total distance traveled is 550m
</span>
<span>to calculate average velocity
550/35 = 16m/s
thus
V_xavg = 16m/s</span>

Answer:
C
Explanation:
As water vapor rises, it cools. Then drops get closer and over time will form clouds.
