A hockey puck slides to a stop on ice. The coefficient of friction between the puck and

the ice is 0.026. What is the puck’s acceleration?

Answers

Answer:

Explanation:

The puck slides on the ice . Coefficient of sliding friction μ = .026

Limiting frictional force = μ R

R is reaction force of the surface .

R = mg

Friction force = μ mg

deceleration = μ mg / m

= μ g

= .026 x 9.8 = .2548

= 0.26 m /s².

How much work is done on a small car if a 1000 N force is exerted to move it 75

Answers

Answer:

75000J

Explanation:

Given parameters:

Force applied on the car  = 1000N

Distance moved  = 75m

Unknown:

Work done  = ?

Solution:

The work done by a body is the force applied to move it through a particular distance.

So;

    Work done  = Force x distance

Therefore;

    Work done  = 1000 x 75  = 75000J

Sandra is riding a water slide at her favorite water park. At the top of the slide,
she has 5,000 J of gravitational potential energy. After a few seconds, she has
1,928 J of gravitational potential energy. What is her kinetic energy at this point,
in J?

Answers

Answer:

3072J

Explanation:

At all points through her slide, it is important to reiterate that energy is always conserved.

Kinetic energy is the energy due to the motion of a body.

Potential energy is the energy due to the position of a body.

Based on the law of conservation of energy, energy is neither created nor destroyed but simply transformed from one form to another.

 So;

At all points:

           Total energy  = Potential energy + Kinetic energy

Since the initial energy  = 5000J which is the potential energy

This is the total energy within the system as the kinetic energy at this point is 0;

 After a few seconds, the potential energy is 1928J;

  Kinetic energy  = Total energy  - potential energy  = 5000J  - 1928J

  Kinetic energy  = 3072J

Answers

Answer: ethanol which will dissolve in both water (a polar solvent) and gasoline (a non-polar solvent)

Explanation:

According to the concept of solubility, ethanol is a molecule which is soluble in both polar and non-polar solvents.

What is solubility?

Solubility is defined as the ability of a substance which is basically solute to form a solution with another substance. There is an extent to which a substance is soluble in a particular solvent. This is generally measured as the concentration of a solute present in a saturated solution.

The solubility mainly depends on the composition of solute and solvent ,its pH and presence of other dissolved substance. It is also dependent on temperature and pressure which is maintained.Concept of solubility is not valid for chemical reactions which are irreversible. The dependency of solubility on various factors is due to interactions between the particles, molecule or ions.

A sample of cobalt-60 has an activity of 2000 Bq. What will the activity be after 10 years? Cobalt-60 has a half life of 5 years.

Answers

Answer:

500.3 Bq

Explanation:

From the formula;

0.693/t1/2 = 2.303/t log (Ao/A)

Where;

t1/12 = half life = 5 years

Ao = initial activity = 2000 Bq

0.693/5 = 2.303/10 log (2000/A)

0.1386= 0.2303  log (2000/A)

0.1386/0.2303 =  log (2000/A)

0.6018 = log (2000/A)

(2000/A) = Antilog (0.6018)

(2000/A) = 3.9976

A = 2000/3.9976

A = 500.3 Bq

Which part of this chemical process requires energy? KOH + HBr - KBr + H20 A. Forming bonds in KOH and HBr B. Breaking bonds in KBr and H2O C. Breaking bonds in KOH and HBr D. Forming bonds in KBr and H2O​

Answers

The chemical process which requires energy is breaking bond in KOH and HBr. Hence, option C is correct.

What is energy?

The capacity to perform work is known as energy in physics. Potential, kinematic, thermodynamic, electromagnetic, chemical, nuclear, and other types are all possible.

As energy is transferred through one body to another, there is also heat and work. As a result, heat transfer may result in thermal energy, whereas labor done may result in mechanical power.

As per the given reaction in the question,

KOH + HBr - KBr + H20

Here, in this reaction the chemical process which requires the energy is at the time of breaking of bonds in KOH and HBr at that time the energy is required.

Therefore, it is concluded that breaking bonds in KOH and HBr i.e., option C is correct.

The only group of elements that DO NOT form ions and are found as monatomic atoms in nature are the: noble gases.

What are noble gases?

The noble gases are a group of chemical elements with comparable qualities; under normal conditions, they are all odourless, colourless, monatomic gases with very minimal chemical reactivity. Historically, they were also known as inert gases and aerogens. Helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and radioactive radon are the six naturally occurring noble gases (Rn).

Oganesson (Og) is a highly radioactive element created synthetically. Although the IUPAC has included oganesson since "group 18" and "noble gas" have been used interchangeably, oganesson may not be appreciably chemically noble and is projected to deviate from the norm and be reactive due to relativistic effects. Its chemistry has not yet been studied due to the single known isotope's relatively brief 0.7 ms half-life.

When a golf club hits a 0.0459 kg ball at rest, it exerts a 2380 N force for 0.00100 s. What is the speed of the ball afterwards? (Unit = m/s)

Answers

Answer:

51.85m/s

Explanation:

Given parameters:

Mass of ball  = 0.0459kg

Force  = 2380N

Time taken  = 0.001s

Unknown:

Speed of the ball afterwards  = ?

Solution:

To solve this problem, we use Newton's second law of motion:

   F = m x [tex]\frac{v - u}{t}[/tex]  

F is the force

m is the mass

v is the final velocity

u is the initial velocity

t is the time taken

        2380  = 0.0459 x [tex]\frac{v- 0}{0.001}[/tex]  

        0.0459v  = 2.38

                   v = 51.85m/s

Answer:

2.38

Explanation:

F = dp/dt  --> dp = F*dt ---> p = F*t if F is constant over time so

p = 2380N* 0.001 s = 2.38 kg-m/s

The diagram shows a tennis ball being thrown vertically into the air. When the ball just left the players hand it is at the speed of 5.0 m/s . The tenis ball has the mass of 0.058 kg. Write down the equation that links kinetic energy to mass and speed

Answers

Answer:

1. KE = ½mv²

2. The kinetic energy of the tennis ball is 0.725 J

Explanation:

The following data were obtained from the question:

Mass (m) = 0.058 kg

Velocity (v) = 5.0 m/s

Kinetic energy (KE) =.?

1. Defining an expression which relates kinetic energy, mass and speed of an object.

Kinetic energy is simply defined as the energy possess by an object in motion. Mathematically, kinetic energy can be represented as:

KE = ½mv²

Where

KE => is the kinetic energy.

m => is the mass of the object.

v => is the velocity of the object.

2. Determination of the kinetic energy of the tennis ball.

Mass (m) = 0.058 kg

Velocity (v) = 5.0 m/s

Kinetic energy (KE) =.?

KE = ½mv²

KE = ½ × 0.058 × 5²

KE = 0.029 × 25

KE = 0.725 J

Thus, the kinetic energy of the tennis ball is 0.725 J.

Calculate the resistance of an electric blanket that draws 9 A to transform 50 W of energy.

Answers

Answer:

The resistance is 0.617Ω.

Explanation:

Given that the formulas are V = I × R and P = I × V so when you substitute the V formula into P formula, you will get P = I² × R. Using this formula, you can find the resistance :

P = I² × R

50 = 9² × R

50 = 81 R

50 ÷ 81 = R

R = 0.617Ω (3sf)

4.02 m/sec² is the acceleration of a 10 kg block that experiences a 50 N applied force as it slides across a horizontal surface.

What is force?

A force is an effect that can alter an object's motion according to physics. An object with mass can change its velocity, or accelerate, as a result of a force. An obvious way to describe force is as a push or a pull. A force is a vector quantity since it has both magnitude and direction.

force = 50 N - frictional force = ma

50 - 9.8 = ma

a = 40.2/10

a = 4.02 m/sec²

4.02 m/sec² is the acceleration of a 10 kg block that experiences a 50 N applied force as it slides across a horizontal surface.
