I get it because I struggle with this myself. First off if it’s a test don’t double check your work because you are typically right the first go around, unless you skip a question. Also once you realize it’s okay to be wrong that helps a lot too. Often times we’re taught from a young age to be afraid of wrong answers for fear of embarrassment or a bad grade. But Science actually shows us that when we get an answer wrong and learn from it our brain physically grows and we’re more likely to remember the correct answer and even be able to explain why it’s correct. Remember “You can fail at what you do but you can never fail with who you are” - Staffan Taylor.
It’s nice to be smart but what’s most important is if you’re a good person. You are not the grade on your test or the grade on your report card, you are so much more. Spread kindness and stay awesome

Answer: Answer: First, You should try to think positive thoughts. Then, you should try and pinpoint your achievements. You often see your failures more than the success. Moreover, you should go check the impostor syndrome in ted ed. If you are trying to be more confident in your school choices than you should try to check the information again or try to go back and remember the time you studied the subject assignments you are doing.

Explanation: That other guy gave a great answer but can you still give a brainliest?

An automobile rounds a curve of radius 50.0 m on a flat road.
bixtya [17]

Answer:

14m/s

Explanation:

Given parameters:

Radius of the curve  = 50m

Centripetal acceleration  = 3.92m/s²

Unknown:

Speed needed to keep the car on the curve = ?

Solution:

The centripetal acceleration is the inwardly directly acceleration needed to keep a body along a curved path.

 It is given as;

      a = \frac{v^{2} }{r}  

a is the centripetal acceleration

v is the speed

r is the radius

  Now insert the parameters and find v;

         v²   = ar

        v² = 3.92 x 50  = 196

         v  = √196 = 14m/s

Two loudspeakers, A and B, are driven by the same amplifier and emit sinusoidal waves in phase. The frequency of the waves emitt
Tamiku [17]

Answer:

7 m .

Explanation:

For destructive interference

Path difference = odd multiple of λ /2

Wave length of sound from each of  A and B.

= speed / frequency

λ = 334 / 172 = 2 m

λ/2 = 1 m

If I am  1 m away from B , the path difference will be

8 - 1 = 7 m  which is  odd multiple of 1 or λ /2

So path difference becomes odd multiple of  λ /2.

This is the condition of destructive interference.

So one meter is the closest distance which I can remain at so that i can hear destructive interference.
