If the maximum moment of force on a door is 10 Nm by an applied force of 2.25 N, then the distance of handle

Answer:

Description.

Explanation:

Motion can be defined as a change in the location (position) of a physical object or body with respect to a reference point.

This ultimately implies that, motion would occur as a result of a change in location (position) of an object with respect to a reference point or frame of reference i.e where it was standing before the effect of an external force.

Mathematically, the motion of an object is described in terms of acceleration, time, distance, speed, velocity, displacement, position, etc.

A reference point refers to a location or physical object from which the motion (movement) of another physical object or body can be determined.

For example, a point on a map is considered to be a reference point because it represents the starting point of an object or person in motion.

Hence, if the reference point changes, the description of position changes, but the actual position does not change.

Answer:

The Acceleration of the object = 6.4 m/s²

Explanation:

Mass of block (m) = 5 kg

Action force on block, (F₁) = 40 N

To Find:

Acceleration of the object (a) = ?

Required solution:

Frictional force opposing the motion (F₂) = 8 N

Here in this question we have to find Acceleration of the object. So, firstly we have to find Net force of block after that we will find Acceleration of the object on the basis of conditions given above

⇒ Net force = Action force on block - Opposing friction force

⇒ F = F₁ - F₂

⇒ F = 40 - 8

⇒ F = 32 N

Now, we have to two elements that used in formula, Net force and Mass of block.

Net force of the block (F) = 32 N

Mass of block (m) = 5 kg

And we have to find Acceleration of the object.

We can find Acceleration of the object by using the Second law of Newton which says F = ma

Here,

F is the Force in N.

m is the Mass in kg.

a is the Acceleration in m/s².

So let's find Acceleration (a) !

† From second law of Newton

⇛ F = ma

⇛ a = F/m

⇛ a = 32/5

⇛ a = 6.4 m/s²

Rutherford tracked the motion of tiny, positively charged particles shot through a thin sheet of gold foil. Some particles traveled in a straight line and some were deflected at different angles. Which statement best describes what Rutherford concluded from the motion of the particles? Some particles traveled through empty spaces between atoms and some particles were deflected by electrons. Some particles traveled through empty parts of the atom and some particles were deflected by electrons. Some particles traveled through empty spaces between atoms and some particles were deflected by small areas of high-density positive charge in atoms. Some particles traveled through empty parts of the atom and some particles were deflected by small areas of high-density positive charge in atoms.

Answer:

Some particles traveled through empty parts of the atom and some particles were deflected by small areas of high-density positive charge in atoms.

Explanation:

Rutherford first proposed the nuclear model of the atom after his landmark experiment.

In this experiment, alpha particles from a source was focused on a thin gold foil. Some of the particles passed through empty spaces within the atom but were deflected at different angles by a small area of high-density positive charge within an atom which Rutherford later called the atomic nucleus.

Hence the answer above.

Answer:

Density = 3 kg/m³

Explanation:

Given the following data;

Volume = 3m³

Mass = 9 kg

To find the density;

Density can be defined as mass all over the volume of an object.

Simply stated, density is mass per unit volume of an object.

Mathematically, density is given by the formula;

[tex]Density = \frac{mass}{volume}[/tex]

Substituting into the formula, we have;

[tex]Density = \frac{9}{3}[/tex]

Density = 3 kg/m³

Answer:

the strength of the magnetic field inside the solenoid is 6.278 x 10⁻³ T.

Explanation:

Given;

length of the wire, = 34.9 m

length of solenoid, L = 0.24 m

radius of the solenoid, r = 0.051 m

current in the solenoid, I = 11.0 A

The number of turns of the wire is calculated as follow;

[tex]N = \frac{34.9}{2\pi \times 0.051} = 109 \ turns[/tex]

The strength of the magnetic field inside the solenoid is calculated as follows;

[tex]B = \mu_0 (\frac{N}{L} )I\\\\B = 4\pi \times 10^{-7} \times (\frac{109}{0.24} )\times 11.0 \\\\B = 6.278 \times 10^{-3} \ T[/tex]

Therefore, the strength of the magnetic field inside the solenoid is 6.278 x 10⁻³ T.

Answer:

Hello your question is poorly written hence I will just give the difference between conduction and convection

answer :

Conduction occurs when there is direct contact between solids and source of heat. while convection occurs when there is transfer of thermal energy due to movement of liquid or gas

Explanation:

when a pot of water is placed on a hot stove the pot is heated through conduction because the metal pot is in direct conduct with the heat from the stove ( which is the primary source of heat in this scenerio ).

while the heat transfer from the hot pot to the water is executed through convection this is because heat transfer via convection requires the movement of liquid or gas.  as the warmer liquid moves over to the top the cooler liquid goes below inside the pot that way the whole liquid becomes warm .

The unique use of gamma radiation is Killing bacteria. The correct option is D.

Gamma radiation is a type of electromagnetic radiation that is highly energetic and has no mass or charge. It is the most penetrating form of radiation and is often emitted during radioactive decay or nuclear reactions. Gamma rays have the shortest wavelengths and highest frequencies in the electromagnetic spectrum, ranging from about 0.1 nanometers to 10 picometers in wavelength. They can cause ionization in matter, meaning they can knock electrons out of atoms or molecules, making them highly damaging to living tissue. Gamma radiation is commonly used in medical imaging and cancer treatment, as well as in industrial applications for sterilization and food preservation.

Here in the Question,

Option A. Detection of thyroid cancer: Gamma radiation is used in medical imaging techniques such as PET scans and SPECT scans to diagnose cancerous conditions, but it is not unique to the detection of thyroid cancer.

Option B. CT scanners: Gamma radiation is not used in CT (computed tomography) scanners. CT scanners use a series of X-rays to produce detailed images of the inside of the body.

Option C. Smoke detectors: Smoke detectors use a small amount of radioactive material, typically americium-241, to ionize air particles and detect the presence of smoke. While gamma radiation is a type of ionizing radiation, smoke detectors do not use gamma radiation specifically.

Option D. Killing bacteria: Gamma radiation is used in the food industry to kill bacteria and sterilize food products, such as spices, meat, and poultry. This is a unique use of gamma radiation, as it relies on its ability to destroy microorganisms at high doses while leaving no residual radiation.

Therefore, The correct answer is option D i.e Killing bacteria.

Answer:

Find answers below.

Explanation:

Velocity can be defined as the rate of change in displacement (distance) with time. Velocity is a vector quantity and as such it has both magnitude and direction.

Mathematically, velocity is given by the equation;

[tex]Velocity = \frac{distance}{time}[/tex]

Speed can be defined as distance covered per unit time. Speed is a scalar quantity and as such it has magnitude but no direction.

Mathematically, speed is given by the formula;

[tex]Speed = \frac{distance}{time}[/tex]

1. Speed: Jackson ran 5k in 24 minutes.

2. Velocity: A storm is travelling 25 km/hour eastward.

3. Speed: John walked 420 m in 17.5 seconds.

4. Velocity: Zart moved the desk 34 cm to the left.

5. Speed: A hurricane travels 360 km in 15 hours.

Answer:

A: Place the ball in the plastic bag, and twist the top so the ball is secure in the bag. Wrap the twisted portion with tape so it stays tight. Use the hole punch or scissors to poke a hole in the part of the bag that’s above the ball. Slip an end of the string through the hole, and tie a knot. This is your pendulum. Hold the loose end of the string still with one hand. With the other hand, raise the ball in an arc so that it’s almost level with the hand holding the string. With the string taut, let the ball go. What do you observe?

Mine was swaying perfectly fine. after a little bit it gradually started swinging slower until stopped.

B: Why did the pendulum stop swinging? Where did the energy go?

gravity was pulling it towards the ground, however the weight and momentum of the ball helped it keep swinging for a good while.

C: Scientists have organized all forms of energy into two types—kinetic and potential. Kinetic [THE ENERGY OF MOTION IN A BODY] energy is the energy of motion, and potential energy [THE STORED ENERGY IN AN OBJECT] is stored energy. At the top of its swing, does the pendulum have kinetic or potential energy?

when its at the very top of the swing it does have a very small amount of time until it starts going back down again but during that time it is potential energy

D: At the bottom of its swing, does the pendulum have kinetic or potential energy?

the pendulum still has kinetic energy when it is the closest to the ground since it is still swinging

E: Think about the process of raising the pendulum to one side and letting it go. For this event, create a list of each form of energy associated with the pendulum as it cycles.

when its in my hand: potential energy

when it starts swinging: kinetic energy

when its going upwards: kinetic energy

when it stops swinging: potential energy

F: How could you give the pendulum more energy?

one way you could possibly make it have more energy is if you make the string longer

G: Now raise the pendulum and let it hit a metal lid or pan. When the ball strikes the lid, what forms of energy can you identify?

I could hear sound energy when the two made contact but for the most part it was kinetic energy
