why isn't the tangential velocity traveling along the circumference of the circle

Answers

Answer 1

Answer:As an equation, the tangential velocity is the distance, 2π r, divided by the time, T. Thus, A point on the circle moves a distance 2π r in a time T. We can extend our equation by looking at a few ideas. These concepts include the angular speed, ω, and the frequency, f. The angular speed, ω, is a speed of rotation.

What is the function (job) of the genes in protein synthesis (how proteins are made in the cell)?

Answers

Answer:

Most genes contain the information needed to make functional molecules called proteins. A few genes produce regulatory molecules that help the cell assemble proteins.

To build proteins, cells use a complex assembly of molecules called a ribosome. The ribosome assembles amino acids into the proper order and links them together via peptide bonds. This process, known as translation, creates a long string of amino acids called a polypeptide chain.

following is NOT a testable
hypothesis that James might develop based on this data?

1. a weaker magnet will pick up more
paperclips than a stronger magnet
2. all magnets pick up paperclips, but the
number of paperclips depends on the
magnet
3. magnets will pick up metal objects but
not plastic objects
4. a stronger magnet will pick up more
paperclips than a weaker magnet

Answers

Answer: 2

Explanation:

The statement "All magnets pick up paperclips, but the number of paperclips depends on the magnet" is neither a hypothesis nor testable.

The hypothesis that is not testable based on the given data is magnets will pick up metal objects but not plastic objects. Option C is the correct answer.

The reason this hypothesis is not testable based on the given data is that the information provided only pertains to the number of paperclips picked up by different magnets. It does not provide any information or evidence regarding the ability of magnets to pick up metal objects versus plastic objects. Option C is the correct answer.

In order to test this hypothesis, we would need data or experiments specifically focusing on the interaction between magnets and metal objects as well as magnets and plastic objects. The given data only provides information about the number of paperclips picked up by different magnets, which does not support or refute the hypothesis about the ability of magnets to pick up different materials.

A 250-turn generator with circular loops of radius 15 cm rotates at 60.0 rpm in a
magnetic field with a strength of 1.00 T.
a. What is the angular speed of the loops?
b. What is the area of one loop?
c. What is the maximum emf?
d. What is the rms emf?

Answers

(a) The angular speed of the loops is 6.284 rad/s.

(b) The area of one loop is 0.071 m².

(c) The maximum emf of the generator is 111.54 V.

(d) The rms emf of the generator 78.87 V.

Angular speed of the loop

The angular speed of the loop is calculated as follows;

[tex]\omega = 60 \ \frac{rev}{\min} \times \frac{2\pi \ rad}{1 \ rev} \times \frac{1 \min}{60 \ s} \\\\\omega = 6.284 \ rad/s[/tex]

Area of the loop

The area of the loop is calculated as follows;

A = πr²

A = π x (0.15)²

A = 0.071 m²

Maximum emf of the generator

emf(max) = NBAω

emf(max) = (250) x (1) x (0.071) x (6.284)

emf(max) = 111.54 V

Rms emf of the generator

Answers

The magnitude of the acceleration a of the astronaut during the throw of the 3.2 kg tool is determined as (18.88)/m.

Force applied to the tool

Based on Newton's third law of motion, the force applied to the tool by the atronaut is equal to the force exerted on the astronaut by the tool.

Fa = - Fb

A motorist drives 5 km east then drives 5 km north. Calculate their distance travelled and their displacement.

Answers

Answer:

See

distance is 10 km

displacement is 5√2 km

Explanation:

DISTANCE:

Distance is scaler so, it doesn't depend on the direction

so distance is 5+5 which is 10

DISPLACEMENT:

Displacement is a vector, so, it depends on direction.

Now when we see north and east, they form a right angle, so we need to calculate the hypotenuse of the triangle for displacement as it is the shortest route between the two points.

Let hypotenuse be h

5² + 5² = h² Moved 5 km in east and north so values are 5h² = 25+25h² = 50h = √50h=5√2

Answers

Answer:

Wave A has a lower frequency than Wave B.

Explanation:

Frequency is the number of waves passing through the unit time.

As the statement of the question says that the coils in wave A are widely and tightly spaced.

While in wave B the coils are widely and very tightly spaced which means the number of coils is more and the frequency of wave B is more than wave A.

Therefore more coils will pass through a fixed point in unite time and more will be the frequency.  

Answer:Wave A has a lower frequency than Wave B.

A loaded spring undergoes simple harmonic motion whose period is proportional to the mass and inversely proportional to the spring constant.

What is simple harmonic motion?

Simple harmonic motion is the periodic motion of an object along a straight line, such that the acceleration of the object is directed towards a fixed point on that line and is proportional to its distance from that point.

Example of a simple harmonic motion is the motion of a loaded spiral spring.

The restoring force on the spring is directly proportional to the extension of the spring and the spring constant.

The period of motion, T when a mass, m is attached to a spring with spring constant k,is given as:

T = 2π√(m/k)

Therefore, a loaded spring undergoes simple harmonic motion whose period is proportional to the mass and inversely proportional to the spring constant.

Answers

Since the equivalent resistance is decreased then current must be increased in the circuit.

What is resistance?

Resistance is defined as the obstruction offered by the circuit in the flow of charge or current.

When three resistors are connected in series then the total equivalent of all three is given by

[tex]R_{eq}=R_1+R_2+R_3[/tex]

Also in this case current is given by

[tex]I=\dfrac{V}{R_{eq}}[/tex]

Now if one of the resistance is removed

Then

[tex]R_{eq}=R_1+R_2[/tex]

let one of the resistance is removed

An object is at rest on a tabletop. Earth pulls downward on this object with a force equal in magnitude to mg. What is the interaction pair to this force

Answers

Answer:

normal contact force

Explanation:

that is the equal and opposite force (as to weight) applied by the table on to the object.

The gravitational force of the earth on the object and the reaction force of the table on the object interact as a pair of forces.

What does gravity mean?

The gravitational force is what pulls things with mass in the same direction. People commonly think about the Earth's gravitational pull. Your body is kept on the ground by this force. Yet, gravity pulls all objects with mass in the same direction.

The gravitational force, or g, is the force that the earth exerts on an object, with g equal to 9.8 m/s2.

The information is ,

Place something on the table.

Now that the item is at rest, a force known as gravitational force pushes it downward from the Earth.

The formula for gravitational force is F = mg, where m is the object's mass.

Moreover, Newton's third law states that every action will always have a corresponding and opposing reaction. When the gravitational force acting between two masses is equal in strength and conducted in the opposite direction, an action and reaction pair is produced.

The reaction force is then given by R = -mg, where m is the object's mass and the negative sign denotes that the force is acting in the opposite direction to that of gravity by earth.

Hence , the interaction pair for gravitational is the reaction force
