Answer 2

Answer: 0.98N for Cylinder A and 2.943N for Cylinder B

Explanation:

Cylinder A = 100g = 100*10^-3kg =0.1kg

Cylinder B = 300g = 300*10^-3kg = 0.3kg

gravitational force g= 9.81m/s^2

For cylinder A Force = mg= 0.1*9.8=0.98N

For Cylinder B Force = mg= 0.3*9.81= 2.943N

On top a coiled spring labeled wave a with coils, which are widely spaced then tightly spaced then widely space. on bottom a coiled spring labeled wave b with coils, which are widely spaced then very tightly spaced then widely space. which statement can be made about waves a and b? wave a has a lower amplitude than wave b. wave a has a higher amplitude than wave b. wave a has a lower frequency than wave b. wave a has a higher frequency than wave b.

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.

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.

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.

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

In a parallel circuit with three resistors connected to a power source, what would happen to the equivalent resistance and current if you removed any one of the resistors? the equivalent resistance would increase and the current would increase. the equivalent resistance would increase and the current would decrease. the equivalent resistance would decrease and the current would decrease. the equivalent resistance would decrease and the current would increase.

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

while current flowing in the open circuit will be given by

(2) An express train of mass 600kg is
moving with a velocity of 180km per
hour.
Calculate its kinetic energy.

Answers

The kinetic energy of the moving express train with the given value of mass and velocity is 7.5 × 10⁵Joules.

What is Kinetic Energy?

Kinetic energy is simply a form of energy a particle or object possesses due to its motion.

It is expressed as;

K = (1/2)mv²

Where m is mass of the object and v is its velocity.

Given the data in the question;

Mass of the train m = 600kgVelocity of the train V = 180kmh = 50m/sKinetic energy of the train K = ?

To determine the kinetic energy of the train, we substitute our given values into the above expression.

K = (1/2)mv²

K = (1/2) × 600kg × (50m/s)²

K = 0.5 × 600kg × 2500m²/s²

K = 750000kgm²/s²

K = 7.5 × 10⁵J

Therefore, the kinetic energy of the moving express train with the given value of mass and velocity is 7.5 × 10⁵Joules.

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 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
