Stels [109]

Answer:6.298,4.1,1.9015

Explanation:

Wavelength=\frac{velocity of sound }{frequency}

=\frac{343}{78}=4.397 m

Distance of 3rd speaker from speaker A is x

From B 78-x

Difference between the distances must be a whole number of wavelengths

First

x-\left ( 8.2-x\right )=4.397    for 1 st wavelength

2x=8.2+4.397=12.597

x=6.298m

second

For zero wavelength

x-\left ( 8.2-x\right )=0

2x=8.2

x=4.1m

Third

\left ( 8.2-x\right )-x=4.397

x=1.9015 m

A car starts from rest and accelerated at a rate of 9m/s squared for 6.5 seconds. How much distance was covered by the car?
ki77a [65]

Answer:

58.5 meters

Explanation:

1. Find your formula. Use distance = speed x time for this problem

2. Plug in the given information. d (for distance) = 9m/s^2 * 6.5 s

3. Multiply number AND units. d = 58.5m

4. Check to make sure units & numbers make sense. In this case check that the answer is a lot bigger than what we stated with and that our units go with distance

I am Lyosha [343]

Answer:

Insight

Explanation:

In psychology insight has been described as a sudden knowledge or solution that just came up especially after several attempts to solve the problem.Like Amira after spending two hours to solution and she has given up before the solution finally came up. Answers or solutions from insights are more reliable that non-insightful answers.

Gestalt Psychology, a 20th century psychologist was the first to carry out as study on insight where he saw it as a sudden seeing the problem in a new way or linking the problem to other problem or solution pair or release certain blockages prevent one from seeing the solution etc.
