Please help! What's the answer to this question, A 5.6 nC electric charge is placed in an Electric Field and experiences a force
zvonat [6]

Answer:

1321 N/C

Explanation:

From the question,

Electric Field (E) = Electric Force(F)/Electric Charge(q)

E = F/q............ Equation 1

Given: F = 7.4 μN = 7.4×10⁻⁶ N, q = 5.6 nC = 5.6×10⁻⁹ C

Substitute these value into equation 1

E = ( 7.4×10⁻⁶)/(5.6×10⁻⁹)

E = 1.321×10³ N/C

E = 1321 N/C

Hence the magnitude of the electric field at that location is 1321 N/C

1: A car traveling at 10 m acceleration uniformly at 2 m. Calculate its velocity after5 s.
s344n2d4d5 [400]

Answer:

20 m/s

Explanation:

v = u + at

v: final velocity

u: initial velocity

a: acceleration

t: time

v = 10 + 2(5)

v = 10 + 10

v = 20 m/s

Explain what the ionosphere is and how it interacts with some radio waves.
kumpel [21]

Answer:

Explained

Explanation:

  • Ionosphere is the outermost layer of the Earth's atmosphere,extending from 60 km to 1,000 km altitude.
  • It mainly consists of ionized gases by the solar radiation.
  • It is very important layer to Earth because it influences the radio propagation to distant places on Earth.
  • Being ionized it reflects high frequency(shortwave) radio waves to the sky as well as to the Earth by a technique called "skip" or "skywave" propagation for the communication over long distances.

An electric charge, A, is placed carefully between two other charges, B and C, and experiences no net electric force. Do B
Brrunno [24]

Answer:

I do not have  enough information to tell

Explanation:

This is deduced due to the fact that if the net force due to B and C on A is zero, the charges on B and C could either be positive or negative depending on the charge on A.
