Answers

Answer 1

The linear velocity of the string is 9.42 m/s. Then the centripetal force acting on the string is 153.8 N.

What is centripetal force ?

Force is an external agent acting on a body to change its motion or to deform it. The force acting on a body which moves across a circular path is called centripetal force.

The centripetal force is related the velocity v and radius of curvature as follows:

Fc = mv²/r

Given angular velocity ω = 60 rpm

linear velocity v = 2πr ω /60 = 2 × 3.14 ×1.5 m×60 /60 = 9.42 m/s

mass = 2.6 kg

Fc = 2.6  kg × (9.42 m/s)² / 1.5 = 153.8 N

Therefore, the centripetal force of the string is 153.8 N.

Any system can transfer energy by the movement of masses across the control boundary, exterior work, or heat transfer across the barrier. These have an impact on the energy reserves of the control volume.

By using first law of thermodynamics -

Q = dU + W

Answers

Correct option is B, By reducing the friction on the pulleys, A pulley system is operating at only 50% efficiency how could the efficiency be increased.

Friction is the force that prevents motion when the surfaces of two objects come into contact. This pulley system requires a lot of force because of the contact force between the pulley and chain.

The application of lubricants can help to lessen this frictional force.

A lubricant is a substance that can lessen the friction between in-contact surfaces, hence reducing the heat generated when the surfaces move. In this way, a pulley system's effectiveness can be improved.

Additionally, we can improve the pulley's effectiveness by reducing its bulk.

Answers

A marble at rest on the floor of a train car is an object in motion relative to the train station. When the train is at rest in the station, the marble is at rest relative to the smooth, horizontal floor of the train car. However, as the train begins to move, the marble will also begin to move relative to the floor of the train car.

As the train enters the station and begins to accelerate, the marble will experience a force due to the acceleration of the train, which will cause the marble to move in the direction of the train's motion. This displacement of the marble relative to the floor of the train car will continue as the train moves through the station.

What is the motion  about?

When the train reaches a constant velocity, the marble will be at rest relative to the floor of the train car, and will stay at that position as long as the train maintains a constant velocity.

When the train begins to decelerate as it approaches the station, the marble will experience a force in the opposite direction of the train's motion, which will cause it to move in the opposite direction of the train's motion, and it will come to a rest on the floor of the train car once the train comes to a complete stop.

In all, the marble's displacement relative to the smooth, horizontal floor of the train car will be zero when the train is at rest, and will increase as the train moves through the station.

What is the law of conservation of momentum?

The law of conservation of momentum states that when two or more bodies are present in an isolated system which are acting upon each other, then their total momentum remains constant before and after the collision until and unless an external force is applied to the system. Therefore, the momentum can neither be created nor destroyed.

m₁u₁ + m₂u₂ = m₁v₁ + m₂v₂

where, m₁ is the mass of object 1 and m₂ is the mass of object 2,

u₁ and u₂ are the initial velocities or the velocity of object 1 and 2 before collision,

v₁ and v₂ are the final velocities or the velocity of object 1 and 2 after collision.

m₁ = 2500kg, u₁ = 32m/s

m₂ = 1500kg, u₂ = 15m/s, v₂ = -3.2m/s

m₁u₁ + m₂u₂ = m₁v₁ + m₂v₂

According to the inverse-square law, both forces are inversely dependent on the square root of the separation between the objects. Also, both forces have proportionality constants. The distance between the items and the relationship between electricity and gravity are inverse.

What parallels and differences exist between electrical and gravitational forces?

Each does their tasks between two others without making eye contact. However, the gravitational pull affects mass while the electric force just affects charge. Unlike electromagnetic currents, which can be both attractive and repellent, gravitational forces are only.

The amount of kinetic energy (KE) depends on the speed of a moving object.
True
False

Answers

Answer: True

Explanation: Kinetic energy is directly proportional to the mass of the object and to the square of its velocity: K.E. = 1/2m x v2. Given that velocity (or speed) is part of the equation, we can say that speed is needed.

You weigh 780 N.

What would you weigh if the Earth were

seven times as massive as it is and its radius

were five times its present value?

Answer in units of N.

Answers

When the Earth becomes seven times as massive as it is and its radius becomes five times its present value, your new weight will be 218.4 N.

What is weight?

The weight of an object is the measure of the effect of acceleration due to gravity on the object.

The formula for the weight of an object is given as;

W = mg

where;

m is massg is acceleration due to gravity

Since mass is constant, the value of weight of an object will change when the value of acceleration due to gravity changes.

The formula for acceleration due to gravity is given as;

g = ( GM ) / ( R² )

where;

G is universal gravitation constantM is the mass of the EarthR is the radius of the Earth

If the Earth were seven times as massive as it is and its radius were five times its present value, the new acceleration due to gravity will be calculated as;

g' = ( G x 7M ) / (5R)²

g' = ( 7 / 25 ) ( GM / R² )

g' = 7/25 (g)

new weight = 7/25 x 780 N = 218.4 N

Which statement is correct about the differences between theories and laws?

A Unlike theories, laws are based on observations obtained through experimentation.

B While both laws and theories are developed on the basis of experimentation, theories are not explanations.

C Unlike theories, laws cannot be changed or replaced because they are statements of fact.

D While both laws and theories are statements, theories are not widely accepted.

Answers

''Unlike theories, laws are based on observations obtained through experimentation'' and ''Unlike theories, laws cannot be changed or replaced because they are statements of fact'' are true statement.

What is the difference between a theory and law?In general, theories explain how a phenomena occurs, whereas laws predict what will happen in a particular scenario based on an equation.Simply put, a theory suggests why something occurs whereas a law predicts what will happen. Although the growth of one frequently spurs advancement on the other, a theory will never mature into a law.A theory does not become a scientific rule as more and better evidence becomes available. Always keep in mind that theories are explanations and laws are the patterns we observe in vast quantities of data that are frequently expressed as equations. A law will always be a law; a hypothesis will always stay a theory.
