In which of the following cases of motions, the distance moved and the magnitude of the displacement are equal?
If the car is moving on a straight road
If the car is moving in circular path
The pendulum is moving to and fro
The earth is moving around the sun
Answer:
answer is number (a) If the car is moving on a straight road....
Explanation:
The distance moved and magnitude of displacement are equal only in the case of motion along a straight line. Because displacement is the shortest path between initial and find path. So, for car moving on straight road, distance moved and magnitude of displacement are equal.

Answer:
1. the graph is showing the speed of the object at different times.
Explanation:
2. the object is slowing down
Choose the correct definitions of speed, velocity, and acceleration. Check all that apply. Acceleration tells us in which direction the object is going. Speed is the rate of change of velocity in time. Acceleration is the rate of change of velocity in time. Velocity is used to describe changes in the movement direction of the object. Acceleration tells us how far the object will go in a certain amount of time. Velocity is used to describe how fast the object is moving and tells us in which direction it is going. Speed is used to describe how fast the object is moving. Velocity is the rate of change of speed in time. Speed is used to describe how fast the object is moving and tells us in which direction it is going.

Which action is due to field forces
Answer:
:)
Explanation:
Raindrops fall on the earth due to gravitational field force. When two magnets come closer to each other, they will either attract or repel each other, which is magnetic field force examples. Without any physical contact, iron pins get attracted towards the magnet as a field force.
How is an apple falling from a tree like the potential difference in a battery?
The gravitational potential energy of a falling apple is similar to the potential difference of a battery because both are energy stored in the object
The gravitational potential energy of a falling apple is maximum when the apple is at maximum height. As the apple begins fall to the ground the potential energy decreases and it will be transformed to kinetic energy.
[tex]P.E_i + K.E_i = P.E_f + K.E_f[/tex]
The potential difference in a battery is total energy stored in the battery.
Thus, the gravitational potential energy of a falling apple is similar to the potential difference of a battery because both are energy stored in the object.
Learn more about gravitational potential energy here: https://brainly.com/question/12314347
The similarity is that both the battery and the falling apple have stored energy.
We define the potential energy of an object as stored energy in that object.
A battery has potential energy, it is stored until you connect it to something and allow that energy to flow.
Similarly, when the apple is in the air it has potential energy, that will be transformed into kinetic energy as it falls (as the apple falls, its velocity increases, thus, the kinetic energy increases).
So both, the apple and the battery have stored energy, and that is the similarity between these two.

if a 5,000 investment earn $1,575 interest over over 18 years what is the annual interest rate
Answer:
I = 1575 / 5000 = 31.5 % interest on investment
(1 + i)^18 = 1.315 where i interest is earned per year
One can use logs or
1 + i = 1.315^1/18 = 1.0153
So the annual interest rate is .0153 or 1.53%
Or
5000 (1 + i)^18 = 6575
(1 + i)^18 = 1.315
18 log (1 + i) = log 1.315
log (1 + i) = .006607
1 + i = 1.0153
i = .0153 = 1.53%

Question 5 (1 point) true or false: Balanced forces acting on an object result in constant velocity True False
Answer:
false
Explanation:
By Newton's first law (An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force), neither speed nor direction change. Our force is balanced.
Balance forces could happen when the object is at rest but not all the time. A balance force is when a object is being push in opposite directions, which would cause the object to stay still or move at a constant speed. Which would mean that balance force could take place when a object is moving or when a object is at rest.

Answer:
O Tightly packed particles in solids slow down the light waves; however, sound waves make particles bounce into each other, so they travel faster in solids.
Explanation:
In the data the student collected, it showed that when the atmosphere is thicker, it slows down the light. With sound however, the sound travels better in thicker stmosphere or solid, than thin air, or steam.
