A concave (convergent) mirror has a focus of 3.4 cm. A tree that is 0.5cm tall is situated 4.5 cm away from the mirror. Calculat
Elanso [62]

The image position is 13.9 cm from the mirror

Explanation:

To solve this problem, we can use the mirror equation:

\frac{1}{f}=\frac{1}{p}+\frac{1}{q}

where

f is the focal length

p is the distance of the object from the mirror

q is the distance of the image from the mirror

In this problem, we have:

f = 3.4 cm is the focal length of the mirror (positive for a concave mirror)

p = 4.5 cm is the position of the object (the tree)

Solving the equation for q, we find the position of the image:

\frac{1}{q}=\frac{1}{f}-\frac{1}{p}=\frac{1}{3.4}-\frac{1}{4.5}=0.0719 cm^{-1}\\q=\frac{1}{0.0719}=13.9 cm

If a net horizontal force of 0.8 N is applied to a toy whose mass is 1.2 kg what acceleration is produced?
julia-pushkina [17]

Answer:

<h2>0.67 m/s²</h2>

Explanation:

The acceleration of an object given it's mass and the force acting on it can be found by using the formula

a =  \frac{f}{m}  \\

f is the force

m is the mass

From the question we have

a =  \frac{0.8}{1.2}   \\  = 0.666666...

We have the final answer as

<h3>0.67 m/s²</h3>

Hope this helps you

This 200-kg horse ran the track at a speed of 5 m/s. What was the average kinetic energy?
MrRissso [65]

Answer:

<h2>2500 J</h2>

Explanation:

The average kinetic energy can be found by using the formula

k =  \frac{1}{2} m {v}^{2}  \\

m is the mass

v is the velocity

From the question we have

k =  \frac{1}{2}  \times 200 \times  {5}^{2} \\   = 100 \times 25

We have the final answer is

<h3>2500 J</h3>

Hope this helps you
