Answer:
the atom cannot be divided into smaller particles
electrons orbit around the center of the atom
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.
Answer:
<h2>918,750 J</h2>
Explanation:
The kinetic energy of an object can be found by using the formula

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

We have the final answer as
<h3>918,750 J</h3>

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

For l = 3.98 m

T = 4 second
For l = 99.4 cm = 0.994 m

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.
