What is the magnification formula?

Physics

The magnification formula is:
M = H (i)/H (o) = -D (i)/D (o)
In other words, the ratio of the image distance and object distance to the ratio of the image height and the object height.

Answer: m = -\dfrac{d_{i}}{d_{o}},m = \dfrac{h_{i}}{h_{o}} and m = -\dfrac{v}{u},

Explanation:

Formula of magnification for lens

Magnification is the ratio of the distance of the image from the lens and distance of the object from the lens.  

m = -\dfrac{d_{i}}{d_{o}}

Magnification is the ratio of the height of the object and height of the image.

m = \dfrac{h_{i}}{h_{o}}

Negative sign represent the inverted image and positive sign represent the virtual image.

Formula of magnification for mirror

Magnification is the ratio of the distance of the image and distance of the object.

m = -\dfrac{v}{u}

4. How much force is required to stop a 60 kg person traveling at 30 m/s during a time of a)
11111nata11111 [884]

Explanation:

F = ma, and a = Δv / Δt.

F = m Δv / Δt

Given: m = 60 kg and Δv = -30 m/s.

a) Δt = 5.0 s

F = (60 kg) (-30 m/s) / (5.0 s)

F = -360 N

b) Δt = 0.50 s

F = (60 kg) (-30 m/s) / (0.50 s)

F = -3600 N

c) Δt = 0.05 s

F = (60 kg) (-30 m/s) / (0.05 s)

F = -36000 N

Mike is a runner. Mike runs 200m in 25s; what is his average velocity during the run? assume that units are in m/s. (asap, will
maw [93]
Velocity is displacement/time
(Displacement is the overall change in distance)

So you’ll want to divide 200 by 25, which should give you:

8 m/s

SCIENCE PLEASE HELPP!!!!

Answer:

A stronger force changes increases velocity more due to increased acceleration on the object if the mass is constant as compared to a weaker force.

Explanation:

Force affects how objects behave in terms of motion, direction, shape etc. When an object is in a state of rest, then force is applied, the object starts to move is a particular direction. Increase in the force applied will make the object to speed up which is to say the velocity will increase.

<u>For example:</u>

When a ball is kicked with a player with a force of 10 N the velocity of the ball is recorded to be 3 m/s. When the player is replaced with a kid the force on the ball is 2 N and its velocity is recorded to be 0.3 m/s.

<u>Reasoning</u>

Increased in force applied on an object increases its acceleration resulting to a higher velocity of the object.

F= m * a --------if  mass is constant , increased force will increase acceleration and speed up the object.
