<h3><u>Answer;</u></h3>
Energy
<h3><u>Explanation;</u></h3>
- A wave is a transmission of disturbance from one point to another. All waves involve transmission of energy from one point called the source to another point.
- <em><u>Waves describes various ways in which energy can be transferred from a point source.</u></em>
- <em><u>In electromagnetic waves</u></em><em>, for instance, </em><em><u>energy transmission occurs as a result of vibrations of electric and magnetic fields</u></em><u>.</u>
- <u><em>In mechanical waves energy transmission is as a result of vibration of particles in the medium used</em></u>. For example in sound waves, energy is transferred through vibration of particles of air or particles of a solid or medium through which sound travels through.
Her magnitude of deceleration on the ice would be 15.126m/s
Answer:
The West is known for "wide, open spaces", cattle, mines, and mountains.
So, <u>the value of the work is approximately 84.65 J</u>.
<h2>Introduction</h2>
Hi ! Here I will help you to discuss the subject about work that caused by force in amount value of angle. Work is affected by the force and displacement.
- If related to the magnitude of the force, the amount of work will be proportional to the magnitude of the applied force. Thats mean, if the value of the force that applied on it is greater, then the value of the work will be greater.
- If related to the magnitude of shift, the amount of work will be proportional to the magnitude of shift of object. Thats mean, if the value of the shift on it is greater, then the value of the work will be greater.
<h3>Formula Used</h3>
The work done by a moving object can be expressed in the equation:
If the Angle Is Ignored
If the Angle Effect on Work
With the following condition:
- W = work that done by object (J)
- F = force that applied (N)
- s = shift or distance (m)
= angle of elevation (°)
<h3>Solution</h3>
We know that :
- F = force that applied =
N - s = shift or distance = 84.9 m
- = angle of elevation = 45°
What was asked ?
- W = work that done by object = ... J
Step by step :
<h3>Conclusion</h3>
So, the value of the work is approximately 84.65 J.
By using the second law of Newton, the frictional force is 200N.
We need to know about the second law of Newton (force) to solve this problem. The total force applied an object is proportional to the mass of object and acceleration. It can be defined as
∑F = m . a
where F is force, m is mass and a is acceleration.
From the question above, we know that
F1 = 200N
v = constant therefore (a = 0 m/s²)
By using second law of Newton, we get
∑F = m . a
F1 - Ffriction = m . 0
200 - Ffriction = 0
Ffriction = 200 N
Hence, the frictional force is 200N.
