Explanation:

A trampoline spring has a force constant k = 800 N/m and is stretched exactly 17.5cm. What is the energy required to do this?

Answers

Answer:

the energy required for the extension is 12.25 J

Explanation:

Given;

force constant of trampoline spring, k = 800 N/m

extension of trampoline spring, x = 17.5 cm = 0.175 m

The energy required for the extension is calculated as;

E = ¹/₂kx²

E = 0.5 x 800 x 0.175²

E = 12.25 J

Therefore, the energy required for the extension is 12.25 J

If a net force acting on a moving object causes its speed to increase, what
happens to the object's momentum?

A. It stays the same.
B. It increases.
C. It changed directions.
D. It decreases.

Answers

Answer:

It increases.

Explanation:

If a force acts in the same direction as the object's motion, then the force speeds the object up. Either way, a force will change the velocity of an object. And if the velocity of the object is changed, then the momentum of the object is changed.

A man pulls a sled at a constant velocity across a horizontal snow surface . If a force of 80 n is being applied to the sled at an 53 degree to the ground . What is the force of friction between sled and snow

Answers

Answer:

Explanation:

The force of 80N is applied on sled at 53⁰

Its horizontal  component = 80cos53

= 48.14 N .

Its horizontal component will pull forward the sled and friction will prevent its forward motion . As sled is moving with constant velocity , net force on it is zero .

Hence forward push = frictional force

Frictional force = 48.14 N.

Why are bananas curved?

Answers

Answer:

Bananas are curved because they grow towards the sun

Explanation:

Bananas are curved so they can retrieve sunlight. Bananas go through a process called 'negative geotropism'. What it means is that bananas grow away from the ground, instead of growing towards it, hence the 'negative' geotropism.

Answer:

Because they grow towards the sun and the sun is what makes things grow like water to  Beneath each flower petal, a row of tiny banana fruits start to grow. Once they're much bigger in size, the fruit goes through a process called negative geotropism. Which basically means instead of continuously grow towards the ground, they start to turn towards the sun, in order to retrieve light.

If continuous spectrum light from a star passes through a cool, low-density gas on its way to your telescope and spectroscope, ____ spectrum on the continuous spectrum results. If continuous spectrum light from a star passes through a cool, low-density gas on its way to your telescope and spectroscope, ____ spectrum on the continuous spectrum results. a bright (emission) line a dark (absorption) line continuous

Answers

Answer:

a dark (absorption) line.

Explanation:

A star is a giant astronomical or celestial object that is comprised of a luminous sphere of plasma, binded together by its own gravitational force.

It is typically made up of two (2) main hot gas, Hydrogen (H) and Helium (He).

Light wave can be defined as an electromagnetic wave that do not require a medium of propagation for it to travel through a vacuum of space where no particles exist.

A telescope can be defined as an optical instrument or device which comprises of a curved mirror and lenses used for viewing distant objects i.e objects that are very far away such as stars and other planetary bodies.

If continuous spectrum light from a star passes through a cool, low-density gas on its way to your telescope and spectroscope, a dark (absorption) line spectrum on the continuous spectrum results, which ultimately implies that the color is being absorbed and the absorption of specific frequencies of light by a hot gas.

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

10-kg box is sliding across an ice rink at 10 m/s . A skater exerts a constant force of 10 N against it. How long will it take for the box to come to a complete stop?

Answers

Answer:

Time, t = 10 seconds

Explanation:

Given the following data;

Mass = 10kg

Force = 10N

Final velocity = 10m/s

Initial velocity = 0m/s

To find the time;

First of all, we would find the acceleration of the box.

Force = mass * acceleration

10 = 10 * acceleration

Acceleration = 10/10 = 1m/s²

Now, we can find the time by using the first equation of motion;

V = U + at

10 = 0 + 1t

10 = t

Time, t = 10 seconds

Therefore, it will take 10 seconds for the box to come to a complete stop.

When a pot of water sits on a hot stove the metal is He did and then transferred into heat to the world of student claims that conduction is the only type feet transfer occurring which statement explains why the students idea is incorrect

Answers

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 .

Answers

Answer:

a.45N

b.52.2N

c.36.45N

Explanation:

note:these answers are based on the fact that the acceleration due to gravity is 10m/s²

*.first of all the tension (T)in the cable is equivalent to the mass(m) of object multiplied by the sum of the opposite and parallel accelerations of the gravity and the elevator respectively.ie. g and a

now that being said mathematically the formula for tension in the cable is given by

T=m(g+a).

a).now for this situation the elevator is stationary,thus has not accelerated,

so a=0

then T=mg; where m=4.5kg g=10ms-²

therefore, T=4.5*10=45N.

b).here the elevator accelerated up, so a is positive.ie.+a

hence T=4.5(10+1.6)=52.2N.

c).here also the elevator accelerated down, so a is negative. is.-a

hence T=4.5(10-1.9)=36.25N.

Answers

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.

6. Speed: Meredith runs 400 meters in 50 seconds.

7. Velocity: Stephen Jay swims 110 m towards the shore in 72 seconds.

8. Velocity: Vince throws a baseball 38 m from third base to first base in 1.7 seconds.
