Answer: E =  7,490.6 N/C
Explanation:
If we have a field E, and a particle with a charge q, the force that the particle experiences is:
F = E*q
In this case, we know that the force is:
F = 1.2*10^(-15) N
And we know that the particle is a proton, where the charge of a proton is:
q = 1.602*10^(-19) C
Then we can replace these two values in the equation to get:
1.2*10^(-15) N = E*1.602*10^(-19) C
We just need to isolate E.
(1.2*10^(-15) N)/(1.602*10^(-19) C) = E
7,490.6 N/C = E
That is the strength of the electric field.
 
        
             
        
        
        
Answer:

Explanation:
Given that,
Initial speed, u = 0
Final speed, v = 40 m/s
Time, t = 2 s
We need to find the acceleration of the aircraft. We know that, acceleration is equal to the rate of change of velocity. So,

So, the acceleration of the aircraft is  .

Answer:

Explanation:
The amplitude of he combined wave is:

A, is the amplitude from the identical harmonic waves
B, is the amplitude of the resultant wave
θ, is the phase, between the waves
The amplitude of the combined wave must be 0.6A:

 
        
             
        
        
        
Answer: 17.83 AU
Explanation:
According to Kepler’s Third Law of Planetary motion <em>“The square of the orbital period of a planet is proportional to the cube of the semi-major axis (size) of its orbit”.  </em>
 (1)
  (1)
Talking in general, this law states a relation between the <u>orbital period</u>  of a body (moon, planet, satellite, comet) orbiting a greater body in space with the <u>size</u>
 of a body (moon, planet, satellite, comet) orbiting a greater body in space with the <u>size</u>  of its orbit.
 of its orbit. 
However, if  is measured in <u>years</u>, and

 is measured in <u>astronomical units</u> (equivalent to the distance between the Sun and the Earth:  ), equation (1) becomes:
), equation (1) becomes:
 (2)
  (2)
This means that now both sides of the equation are equal.
Knowing  and isolating
