Can you tell from an FBD if an object is moving or not? Explain your response.
Answers
Answer:
Yes it is possible to tell if an object is moving or not using a FBD based on Newton's Laws of Motion
Explanation:
A Free Body Diagram is the representation of an object in a diagram that shows (all) the vector of the forces that act on the object
When the sum of all the force vectors acting on the body give a resultant force the object will move in the direction of the force according to Newton's First Law of motion, which states that an object will continue in its rest state or continue its uniform motion on a straight path unless a force acts on the object
The net force, 'F', can be represented according to Newton's Second Law of motion which is F = m·a, where 'a' represents the acceleration (rate of change in velocity) of the object as the object begins to move from rest
Therefore;
From a FBD it is possible to tell if an object is moving or not.

Answers
Answer:
Equivalent resistance of the circuit is 116 ohm.
Explanation:
Finding the equivalent resistance of the circuit. Since, 29 ohm resistors are connected in series, so
→ Equivalent resistance = R_1 + R_2 + R_3 + R_4
→ Equivalent resistance = (29 + 29 + 29 + 29) ohm

A 3.00 x 10-2-kg block is resting on a horizontal frictionless surface and is attached to a horizontal spring whose spring constant is 124 N/m. The block is shoved parallel to the spring axis and is given an initial speed of 11.9 m/s, while the spring is initially unstrained. What is the amplitude of the resulting simple harmonic motion
Answers
Answer:
[tex]A=0.185m[/tex]
Explanation:
From the question we are told that
Mass of Block [tex]M=3*10^-2kg[/tex]
Spring constant [tex]\mu=124 N/m[/tex]
Initial Speed [tex]V_1=11.9m/s[/tex]
Generally the equation for Kinetic Energy is mathematically given by
[tex]K.E=1/2 mv^2[/tex]
Therefore
[tex]K.E_1=1/2*0.03*11.9^2[/tex]
[tex]K.E_1=2.12J[/tex]
Where
[tex]Initial K.E_1=Final K.E[/tex]
Generally the equation for Final Energy stored is mathematically given by
[tex]K.E_2=0.5\mu a^2[/tex]
Therefore
[tex]K.E_1=K.E_2[/tex]
[tex]0.5\mu A^2=2.12J[/tex]
[tex]A=\sqrt{\frac{2.12}{0.5*124}}[/tex]
[tex]A=0.185m[/tex]
Therefore the amplitude of the resulting simple harmonic motion is
[tex]A=0.185m[/tex]

Answers
Answer:
q = 0.036 C
Explanation:
Given that,
Current passes through a defibrillator, I = 18 A
Time, t = 2 ms
We need to find the charge moved during this time. We know that,
Electric current = charge/time

An object is moving at 4.66 m/s when it accelerates at 5.66 m/s2 for a period of 2.35 s. The distance it moves in this time is ____ m.
Answers
Answer:
S = 26.58 meters
Explanation:
Given the following data;
Initial velocity = 4.66 m/s
Acceleration = 5.66 m/s²
Time = 2.35 seconds
To find the distance travelled by the object, we would use the second equation of motion;
S = ut + ½at²
Where;
S represents the displacement or height measured in meters.
u represents the initial velocity measured in meters per seconds.
t represents the time measured in seconds.
a represents acceleration measured in meters per seconds square.
Substituting into the equation, we have;
S = 4.66*2.35 + ½*5.66*2.35²
S = 10.951 + (2.83 * 5.5225)
S = 10.951 + 15.629
S = 26.58 meters

What would be the force required to accelerate an object that weighs 35 N up at a rate of .60 m/s^2?
Answers
Answer: [tex]2.14\ N[/tex]
Explanation:
Given
Force required to accelerate the object at the rate of [tex]0.6\ m/s^2[/tex]
The weight of the object is [tex]W=35\ N[/tex]
Mass of the object can be identified by dividing the weight by acceleration due to gravity
[tex]\Rightarrow m=\dfrac{W}{g}\\\\\Rightarrow m=\dfrac{35}{9.8}\\\\\Rightarrow m=3.57\ kg[/tex]
[tex]\therefore \text{Force F=}m\times a\\\Rightarrow F=3.57\times 0.6\\\Rightarrow F=2.14\ N[/tex]

What do you think is the factor that causes projectile path to bend?
Answers
Wind and gravity
Explanation
Wind can push objects different directions. It can even push bigger objects if there is a strong wind current. Gravity is a force that is constantly on earth and can force things to move or in this case, bend in projection. (Please give brainliest thx)
The movement of an object in a curved path toward the ground due to the application of a horizontal force and the downward force of gravity is projectile motion. The gravity is the factor that leads to bend of projectile path.
What is gravity?Gravity is the universal force of attraction that holds all matter together. It is by far the weakest known natural force and thus has no influence on the internal properties of everyday matter.
A projectile is an object whose main force is gravity. Because gravity is a downward force, it causes a projectile to accelerate downward.
Thus, the factor that causes projectile path to bend is gravity.

You are out in your sail-boat and the wind stops blowing when you arr 20 meters from shore- you are stuck. You have no paddles in the boat and are not able to reach the water to push with your body use Newton's third law of motion to identify what you can do to get to shore using the box of apples you find in the boat
Answers
Answer:
According to Newton's third law, throwing the apples in the opposite direction to the shore with a force, F₁, one after the other, repeatedly, pushes the both towards the shore with a force also equal to F₂ until the boat reaches the shore
Explanation:
The given parameters are;
The distance of the boat from the shore = 20 meters
The available propulsion devices = A box of apples
According to Newton's third law of motion states that action and reaction are equal and opposite
Therefore, according to Newton's third law, by throwing the apple into the water in the opposite direction to the shore, such that each apple of mass m₁, is given an acceleration a₁, will result in a force, F₁ = m₁a₁ in the direction away from the shore
According to Newton's third law of motion, the force F₁, will result in an opposite reaction force F₂ in the direction of the shore, such that as F₁ is made large by giving a higher acceleration, a₁ the apples, reaction force on the occupant of the boat , who is throwing the apple, F₂, increases
F₁ = -F₂
Where;
F₂ = m₂·a₂
a₂ = The acceleration of the boat and the occupant
m₂ = The mass of the boat and the occupant
Given that the mass, m₂, is constant, the acceleration of the boat and occupant, a₂, increases as F₁ increases, increasing the speed of the boat from zero to positive value above zero m/s and the boat moves towards the shore

Describe succinctly the relationship between how far a galaxy is from us (its distance), versus how fast it is moving.
Answers
Answer:
Distance is directly proportional to the velocity
Explanation:
In 1929, Edwin Hubble's wrote an article that talked about relationship between the distance and recession speed/velocity of galaxies which led to what is known as the Hubble Law. This law states that galaxies are moving away from the earth at velocities proportional to their distances.
Thus is written as;
v = H_o•d
Where;
v is velocity
d is distance
H_o is Hubble's constant rate of cosmic expansion.
He came to this conclusion by generating a graph known as Hubble's classic graph which was a graph of observed velocity vs distance for nearby galaxies.
