Answer:
q = -2.19 x 10⁻⁵ C
Explanation:
Given;
mass of the particle, m = 1.5 g = 0.0015 kg
magnitude of electric field, E = 670 N/C
Electric field is given by;
where;
q is the magnitude of the
f is the force of the charge
f = mg
Since the electric field is acting downward, the force on the charge must be acting upward. Therefore, the charge must be negative
q = -2.19 x 10⁻⁵ C
Answer:
Radio waves are electromagnetic waves
Explanation:
•Radio waves are electromagnetic waves.
•Satellites are located within our atmosphere.
•Radio waves are very high energy mechanical waves.
•Radio waves are changed to gamma rays for transmission.
Answer: Transverse waves have motion perpendicular to velocity, while longitudinal waves have motion parallel to velocity.
Explanation:
Transverse waves are characterized by the fact that the particles of the medium in which they propagate move transversely to the direction of propagation of the wave.
In other words,<u> its displacement is perpendicular to the direction of propagation of the wave</u>, being a good example the circular waves in the water.
On the other hand, Longitudinal waves are characterized by the fact that <u>the oscillation of the particles in the medium is parallel to the direction of propagation of the wave.</u> A good example of this is the sound wave.

Acceleration of the cabinet= 0956 m/s²
Explanation:
Total force=25+18=43 N
mass of cabinet=45 kg
now F = m a
a= F/m
a=43/45
a=0.956 m/s²
Thus the acceleration of the cabinet=0.956 m/s²
