Of course. Wind is air in motion, and the gases in air are composed of
all the usual familiar stuff ... atoms, molecules, mass, etc. That's how
the wind moves things ... it has momentum and kinetic energy, which
get transferred to the things that move in the wind.</span>

Answer:
The following options are true based on the properties of electric field;
a) Electric field lines near positive point charges radiate outward.
b) The electric force acting on a point charge is proportional to the magnitude of the point charge.
d) In a uniform electric field, the field lines are straight, parallel, and uniformly spaced.
Explanation:
From option b) From coulomb's law F = Kq1q2r/r2
Answer:
Explanation:
given,
P (in kilo pascals), volume V (in liters), temperature T (in kelvins)
P V = 8.31 T
Rate of increase the temperature = 0.1 K/s
temperature = 285 K
Pressure = 18 kPa
increasing at the rate of 0.07 k Pa/s
Rate at which volume is changing = ?
<span>A Doppler radar system transmits radio waves off of objects
and receives what bounces back.
The system measures the difference between the frequency
of the waves it sends and the frequency of the waves it receives.
If the waves come back at a higher frequency than they were sent,
that means the object is moving toward the radar antenna.
If the waves come back at a lower frequency than they were sent,
that means the object is moving away from the radar antenna.
This is kind of what choice-A is trying to say.
