During a testing process, a worker in a factory mounts a bicycle wheel on a stationary stand and applies a tangential resistive force of 130 N to the tire's rim. The mass of the wheel is 1.70 kg and, for the purpose of this problem, assume that all of this mass is concentrated on the outside radius of the wheel. The diameter of the wheel is 50.0 cm. A chain passes over a sprocket that has a diameter of 8.75 cm. In order for the wheel to have an angular acceleration of 3.50 rad/s2, what force, in Newtons, must be applied to the chain
Answers
Answer:
The force that must be applied to the chain in order for the chain to have the given acceleration is approximately 694.2 N
Explanation:
The given restive force, [tex]F_f[/tex] = 130 N
The mass of the wheel, m = 1.70 kg
The diameter of the wheel, D = 50.0 cm
∴ The radius of the wheel, R = 50.0 cm/2 = 25.0 cm = 0.25 m
The diameter of the sprocket over which the chain passes, d = 8.75 cm
The radius of the sprocket over which the chain passes, r = 8.75 cm/2 = 4.375 cm = 0.04375 m
The angular acceleration, α = 3.50 rad/s²
Torque, τ = I·α
Where;
I = The moment of inertia = m·R²·α
The net torque = The applied torque - The friction torque
Therefore, we get;
I × α = m × R² × α = F × r - [tex]F_f[/tex] × R
1.70 kg × (0.25 m)² × 3.50 rad/s² = F × 0.04375 m - 120 N × 0.25 m
F = (1.70 kg × (0.25 m)² × 3.50 rad/s² + 120 N × 0.25 m)/(0.04375 m) = 694.214286 N
The force that must be applied to the chain in order for the chain to have the given acceleration, F ≈ 694.2 N

Answers
Answer:
Kinetic energy is energy possessed by a body by virtue of its movement. Potential energy is the energy possessed by a body by virtue of its position or state. While kinetic energy of an object is relative to the state of other objects in its environment, potential energy is completely independent of its environment.
Both energies are related to motion.

Answers
Answer:
1.5 m/s ; - 1.5 m/s²
Explanation:
F = ma
F = Force ; m = mass of body ; a = Acceleration
Hence,
a = F/m
F = 6N applied in the direction of motion of the. Body
a = 6N / 4 kg
a = 1.5 m/s² in the direction of motion.
If the force is applied in the opposite direction of motion :
F = ma
a = F/m
a = 6 / 4
a = 1.5 m/s²
Simc efoece is applied in the opposite direction of motion :
We have a negative acceleration (deceleration) = - 1.5 m/s²

This is vety hard this is level 4 number 10 on code.org plsss help me
Answers
Answer:
Explanation:
Coding is all about logic, since I do not have the actual problem from the website I will guide you on how to solve this.
Since you need to go a certain direction you will need to indicate to the character which direction to go. Next, we need to prevent the player from travelling through a wall, we can accomplish this using an IF/ELSE statement. IF the next block in that direction is a wall then do not move forward, ELSE move forward. We would call this statement every time the player tries to move in any direction. Finally, once we reach the lettuce we need to continue picking it until there is no more. To do this we use a While loop, that checks to see if there is any more lettuce, if there is it will run the code to pick up lettuce, if there is NO more then the While loop will exit. That would be the entire code.

If the current in a wire which is placed perpendicular to a magnetic field increases the force on the wire
Answers
Answer:
The force on the wire increases
Explanation:
Since the force on the wire F = BILsinФ where B = magnetic field strength, I = current in wire, L= length of wire and Ф = angle between the magnetic field and the wire.
Given that the magnetic field and the wire are perpendicular, Ф = 90°
So, F = BILsin90° = BIL
Since B and L are constant, F ∝ I
So, if the current in the wire increases, the force on the wire also increases.

Answer:
“We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain unalienable Rights, that among these are Life, Liberty and the pursuit of Happiness." So, This is connected to the biblical worldview and teaching in the sense that everyone is created with an equal opportunity or chance to live. No one is created literally equal or we would all look the same, talk the same, and think the same. Instead, we all have an opportunity at life and to live. Also, we all have the right to pursue happiness. Sin provides a certain happiness in our lives. It provides short-term happiness that corrupts us. In the “Declaration of Indepence”, sin is a pursuit of happiness, but also doing good is too. They meant that we should pursue what God says is good happiness. For instance, doing nice things to people and serving them. This makes me happy and every other human being that is not narcissistic or a robot. That happiness is joy and it does not come from our circumstances, but from the happiness in our hearts that shows a relationship with God.

You are rolling a ball in a veiled by kicking it. You get tired and stop kicking the ball. What happens to the potential energy of the ball.
Answers
Answer:
The potential energy of the ball becomes 0
Explanation:
When kicking the ball, and it moves up, the potential energy of the ball increases. When the ball descends downwards, the potential energy of the ball reduces.
This is so because potential energy increases as height increases and decreases when there is a reduction in height.
So, when you stop kicking the ball and you place the ball on the floor, the ball becomes static (motionless); hence, the potential energy becomes 0.

Please help! What's the answer to this question, A 5.6 nC electric charge is placed in an Electric Field and experiences a force of 7.4 μN. What is the magnitude of the Electric Field at that location?
Answers
Answer:
1321 N/C
Explanation:
From the question,
Electric Field (E) = Electric Force(F)/Electric Charge(q)
E = F/q............ Equation 1
Given: F = 7.4 μN = 7.4×10⁻⁶ N, q = 5.6 nC = 5.6×10⁻⁹ C
Substitute these value into equation 1
E = ( 7.4×10⁻⁶)/(5.6×10⁻⁹)
E = 1.321×10³ N/C
E = 1321 N/C
Hence the magnitude of the electric field at that location is 1321 N/C

A fisherman sees 7 wave crests go by in 10.0 s. The crests are 2.43 m apart. Find the frequency of the wave. (Unit = Hz)
Answers
Answer: 0.7
Explanation:
A fisherman sees 7 wave crests go by in 10 s, with wavelength (λ) ia 2.43 m has the frequency of the wave is 0.7 hertz.
What is a wave?A wave is defined as the propagation of distrubance from one place to another. It can carries energy when it propagates into the medium without the net movement of the particles.
It refers to the variations or flow of energy without the transfer of mass of particles or matter. The waves can be visible or invisible. Light and sound are travel in the form of waves.
In waves, the wavelength, frequency, wavespeed and time period can be identified. Frequency refers to the number of oscillations takes place per unit time. It is measured in hertz (Hz).
Wavelength(λ) defines the distance travelled by the wave in a particular time in one vibration. It is also defined as the spatial period of the wave. It can be obtained by taking ratio between wavespeed and frequency. The unit of wavelenght is meter(m).
Wavespeed of the wave equals the wavelength and frequency. It defines the distance travelled/ number of meter covered by given time. Wavespeed (v) = wavelength (λ) / frequency (f). Its unit is m/s.
Time period is inversely proportional to the frequency (f). The time taken by the wave to complete its one oscillation is called time period. Time period = 1 / f . Its unit is seconds (s).
From the given,
time = 10 secs
no of waves = 7
wavelength = 2.43 m
To obtain frequency from the givens, the formula for frequency is:
frequency = no.of.cycles of waves / time taken
= 7 / 10
f = 0.7 hertz.
Hence, the frequency of the wave is 0.7 Hz for 7 waves and given time 10 s.

the soft ballplayer does 9876 joules of work when hitting a ball into center field. Assuming the ball landed 100 meters away from home plate, how much force did the player use to hit the ball?
Answers
Answer:
F = 987600 N
Explanation:
Force Equation
F=ma
Newton's second law states that force is proportional to what is required for an object of constant mass to change its velocity. This is equal to that object's mass multiplied by its acceleration. We use Newtons, kilograms, and meters per second squared as our default units, although any appropriate units for mass (grams, ounces, etc.) or velocity (miles per hour per second, millimeters per second2, etc.) could certainly be used as well - the calculation is the same regardless.
Solve
F = m * a
F = 100 kg * 9876 m/s2
F = 987600 N
Newtons are derived units, equal to 1 kg-m/s². In other words, a single Newton is equal to the force needed to accelerate one kilogram one meter per second squared.
