Where must an object be placed to form an image 30.0 cm from a diverging lens with a focal length of 43.0 cm?
Schach [20]
Using lens equation;

1/o + 1/i = 1/f; where o = Object distance, i = image distance (normally negative), f = focal length (normally negative)

Substituting;

1/o + 1/-30 = 1/-43 => 1/o = -1/43 + 1/30 = 0.01 => o = 1/0.01 = 99.23 cm

Therefore, the object should be place 99.23 cm from the lens.

Determine the kinetic energy of a 1500 kg roller coaster that is moving with a
olga2289 [7]

Answer:

<h2>918,750 J</h2>

Explanation:

The kinetic energy of an object can be found by using the formula

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

m is the mass in kg

v is the velocity in m/s

From the question

m = 1500 kg

v = 35 m/s

We have

k =  \frac{1}{2}  \times 1500 \times  {35}^{2}  \\  = 750 \times 1225 \\  = 918750

We have the final answer as

<h3>918,750 J</h3>

Hope this helps you

What is the period of a 3. 98 m long pendulum? What is the period of a 99. 4 cm long pendulum?.
madam [21]

A pendulum's time period is the amount of time it takes to complete one oscillation. The pendulum with a length of 3.98 m and a length of 99.4 cm will have a time period of 4 and 1.99 seconds, respectively.

<h3>What is the definition of a simple pendulum?</h3>

A simple pendulum is a device with a point mass hanging from fixed support and connected to a light inextensible thread.

The vertical line going through the fixed support represents the mean position of a basic pendulum.

h = vertical distance from the point of suspension

L = length of the simple pendulum

The time period of the simple penduum is given by

\rm T = 2\pi\sqrt{\frac{l}{g} }

For l = 3.98 m

\rm T = 2\times 3.14 \sqrt{\frac{3.98}{9.81} }

T = 4 second

For  l = 99.4 cm = 0.994 m

\rm T = 2\times 3.14 \sqrt{\frac{0.994}{9.81} }

T = 1.99 second

The time period of the pendulum having 3.98 m and 99.4 cm in length will be 4  and 1.99 seconds respectively.
