Answer: 5 cm</h2>
In convex mirrors the focus is virtual and the focal distance is negative. This is how the reflected rays diverge and only their extensions are cut at a point on the main axis, resulting in a virtual image of the real object .
The Mirror equation is:
(1)
Where:
is the focal distance
is the distance between the object and the mirror
is the distance between the image and the mirror
We already know the values of 
and 
, let's find from (1):
(2)
(3)
On the other hand, the magnification 
of the image is given by the following equations:
(4)
(5)
Where:
is the image height
is the object height
Now, if we want to find the image height, we firstlu have to find from (4), substitute it on (5) and find :
Substituting (3) in (4):
(6)
Substituting (6) in (5):
Finally we obtain the value of the height of the image produced by the mirror:
Answer:
1.11 dioptre
Explanation:
= Distance of the image = - (125 - 2) = - 123 cm
= Distance of the object = 54 - 2 = 52 cm
= Focal length of the lens
Using the equation
cm
Power of the lens is given as
Dioptre
They are used to be able to go out of Earth and into space to Be able to explore and toBe able to prove and tell about Earth and space
Answer:
The displacement in t = 0,
y (0) = - 0.18 m
Explanation:
Given f = 40 Hz , A = 0.25m , μ = 0.02 kg / m, T = 20.48 N
v = √ T / μ
v = √20.48 N / 0.02 kg /m = 32 m/s
λ = v / f
λ = 32 m/s / 40 Hz = 0.8
K = 2 π / λ
K = 2π / 0.8 = 7.854
φ = X * 360 / λ
φ = 0.5 * 360 / 0.8 = 225 °
Using the model of y' displacement
y (t) = A* sin ( w * t - φ )
When t = 0
y (0) = 0.25 m *sin ( w*(0) - 225 )
y (0) = 0.25 * -0.707
y (0) = - 0.18 m
Answer:
Hewo My Lovelys!!
Answer is down below!!
Explanation:
The answer is C) The nail exerts an equal force on the hammer in the opposite direction.
Reason: The Newtons third law states that there is an equal an opposite reaction for every action. When hammer pushes the nail, the nail will push the hammer back in opposite direction. When the hammer hits a nail then nail will exert the equal and opposite force to the hammer. These both objects will exert force on each other in opposite directions.
Hope this helps!! =3
Have a great day, evening, of night!! <3
