The angle of bob displacement should be small

<h3>Simple pendulum</h3>

The simple pendulum a system that moves in an oscillatory motion. It consist of a suspended mass on a string with length placed on a fixed support.

The acceleration due to gravity can be measured using a simple pendulum. During this experiment:

The fan should be switched off to prevent air resistance
The stopwatch zero error should be noted and corrected
The angle of bob displacement should be small

1) what is the potential energy at the end of the loop?

AlexFokin [52]

The potential energy at the end of the loop is equal to 0.3407 Joules.

<u>Given the following data:</u>

Mass of rock = 102.16 g to kg = 0.10216 kilogram.

Height of the loop = 34 cm to m = 0.34 meter.

Acceleration due to gravity = 9.8 $m/s^2$

<h3>What is potential energy?</h3>

Potential energy (P.E) refers to the energy that is possessed by an object due to its position (height) above planet Earth.

Mathematically, potential energy (P.E) is given by this formula;

$P.E = mgh$

<u>Where:</u>

m is the mass of an object.

g is the acceleration due to gravity.

h is the height of an object.

Substituting the given parameters into the formula, we have;

$P.E = 0.10216 \times 9.81 \times 0.34$

P.E = 0.3407 Joules.

<h3>What is kinetic energy?</h3>

Kinetic energy (K.E) refers to an energy that is possessed by a physical object due to its motion.

Mathematically, kinetic energy (K.E) is given by this formula;

$K.E = \frac{1}{2} MV^2$

<u>Note:</u> You'll have to calculate the velocity from the distance traveled by the car and photogate time in your experiment.

Based on the law of conservation of energy, we can deduce the following points:

Potential energy (P.E) is <u>highest</u> at the top of the loop while kinetic energy (K.E) is <u>lowest</u>.

Kinetic energy (K.E) is <u>highest</u> underneath the loop while potential energy (P.E) is <u>lowest</u>.

The inertia with the speed of 2.9 m/s has moved a distance of 3.6 kilometers in the west direction and 2.35 kilometers in the north direction.

<h3>What are trigonometric ratio?</h3>

In mathematics, the trigonometric functions are real functions which relate an angle of a right-angled triangle to ratios of two side lengths. They are widely used in all sciences that are related to geometry, such as navigation, solid mechanics, celestial mechanics, geodesy, and many others.

Given:

Speed of the speed 2.9 m/s

The direction in which the inertia change is moving = 43° north west.

Time taken to travel the distance = 30 minutes

According to the question that is moving in a Northwest direction with a velocity of 2.9 m per second.

If you want to find the distance it has moved in either North or west direction you will first have to find the total distance that kayak has moved in 30 minutes.

The distance travel by the kayak in 30 minutes = speed of person × time taken

The distance travel by the person in 30 minutes = 2.9 × 30 × 60

The distance travel by the person in 30 minutes = 5220 metre

The distance travel by the person in 30 minutes = 5.22 km

The distance traveled in the west direction can be find using trigonometric ratio.

5.2 × sin 43 = The distance traveled in the west direction

The distance traveled in the west direction = 3.6 kilometers

The distance traveled in the west = cos 43 × 5.2

The distance traveled in the west = 2.35 km

Therefore, The person with the speed of 2.9 m/s has moved a distance of 3.6 kilometers in the west direction and 2.35 kilometers in the north direction.

The speed of sound in aluminum is 5200 m/s. Can you hear a sound with a

romanna [79]

Answer:

v = wavelength * frequency

frequency = 5200 m/s / .2 m = 26000 / sec

20,000 / sec is optimistic for the upper frequency of human hearing

So 26,000 is above the hearing range for human ears
