If acceleration is calculated using the equation, "change in velocity/change in time,"

Physics
1 answer:
ki77a [65]4 years ago
3 0

Answer:

0.1m/s^2

Explanation:

Acceleration = change in velocity /change in time

Initial velocity u=0

Initial time=0

a=v-u/t2-t1

a=1.2-0/12-0

a = 1.2/12= 0.1m/s^2

Changing to meter per second :

120cm/s= (120/100)=1.2m/s,

Therefore,acceleration=0.1m/s^2.

ad-work [718]

Answer:

True A and B

Explanation:

Let's propose the solution of the exercise before seeing the affirmations.

We use the law of refraction

      n₁ sin θ₁ = n₂. Sin θ₂

Where n₁ and n₂ are the refractive indices of the two means, θ₁ and θ₂ are the angles of incidence and refraction, respectively

      sin θ₂ = (n1 / n2) sin θ₁

Let's apply this equation to the case presented. The index of refraction and airs is 1 (n1 = 1)

     Sin θ₂ = (1 / n2) sin θ₁

 the angle  θ₂ which is the  refracted angle is less than the incident angle

Let's analyze the statements time

A. False. We saw that it deviates

B. True Approaches normal (vertical axis)

C. False It deviates, but it is not parallel to normal

D. False It deviates, but approaching the normal not moving away

E. True. Because its refractive index is higher than air,

What is the speed of a wave if the wavelength is 50 meters and the period is 10 seconds?
Karolina [17]
Based on the information you provided, this means the wave is traveling 50 meters every ten seconds. Meaning it is traveling 50/10 meters per second.
When you simplify you get 5 meters per second.

Jessie draws a ray diagram to show how an image of a candle is produced by a concave mirror when the candle is placed in front o
irina1246 [14]
There are two rules of reflection for the concave mirror:
1)<span>Any incident ray traveling parallel to the principal axis on the way to the mirror will pass through the focal point upon reflection.
2)</span><span>Any incident ray passing through the focal point on the way to the mirror will travel parallel to the principal axis upon reflection.
Also, keep in that for concave mirror center of curvature is 2f.
Using these two rules we can construct the image. 
You should always use these two "special" rays, I will mark then 1 and 2 on the picture.
From the picture, we can see that if you place the object between the focus and vertex you get the virtual image.
The answer is: object should be between the focal point and the vertex</span>

When you get a tooth pulled it leaves a big hole in your mouth. Eventually, that hole closes. How does that hole close
Virty [35]
It doesn’t, a new tooth underneath your old one starts to push the right old one out, then the tooth comes loose and the tooth underneath continues growing.
Hope my answer helps!
