Two radio antennas A and B radiate in phase. Antenna B is a distance of 130 m to the right of antenna A. Consider point Q along
hoa [83]

Answer:

constructive  λ = 130 m

destructive  λ = 260 m

Explanation:

a) the expression for constructive interference is that the difference in amino is equal to a multiple of the average wavelength

                   AQ - BQ = 2m λ/ 2       m = 0, 1, 2, ...

                     

Where

     AQ = 130 +50 = 180 m

     BQ = 50 m

To find the smallest wavelength let's use m = 1

                       180 - 50 = 2 1 λ/ 2

                        λ = 130 m

b) for destructive interference

                 AQ –BQ = (2m + 1) λ/2

The smallest value is for m = 0

                  130 = λ / 2

                  λ = 260 m

An object is moving with an initial velocity of 19 m/s.It is then subject to a constant acceleration of 2.5 m/s for 15s.How far
bija089 [108]

Answer:

566.3 m

Explanation:

The distance travelled by the object can be found by using the SUVAT equation:

d=ut+\frac{1}{2}at^2

where

u is the initial velocity

t is the time

a is the acceleration

For the object in this problem:

u = 19 m/s

a = 2.5 m/s^2

Substituting t = 15 s, we find the distance travelled:

d=(19)(15)+\frac{1}{2}(2.5)(15)^2=566.3 m
