Answer:
the lens is located in the eye. by changing its shape, the lens changes the focal distance of the eye. in other words,it focuses the light rays that pass through it (and onto the retina) in order to create clear images of objects that are positioned
at various distances.
Answer:
b. calculate the constant force exerted on the pole vaulter due to the collision
mbgiclbxhkr and you can see the pole and you are not to be a great friend of the day and night sweets is my first day of your life and my friends is my friend
Velocity = displacement / time
First, Always make sure that your units for things are the same. In this question, we are given time in seconds and hours. So, we need to make them all use 1 unit.
I will do seconds.
To convert 80km/h to m/s, divide by 3.6.
22.2222…. m/s = displacement / 2.1s
Multiply by 2.1s on both sides
46.6666……m = displacement
You travelled 47 meters.
Answer:
a. 28.27 m/s
b. 12.75 m/s
c. No
Explanation:
a.
The bottom
Ek = Ep
¹/₂ * m * v² = m * g * h₁
v = √ 2 * g * h₁ = √ 2 * 9.8 * 40.8 m
v = 28.27 m/s
b.
At the top
Ek = Ep
¹/₂ * m * v² = m * g * h₁
v = √ 2 * g * h₁ = √ 2 * 9.8 * (40.8 - 32.5) m
v = 12.75 m/s
c.
No in this case the axis is the same of the motion so, the angle doesn't affect the result
