Answer:

True

Explanation:

1 ton = 10 quintals

Answer:

The second box

Explanation:

Work done is the force applied to move a body through a particular distance.

Work done  = Force x distance

For the first box:

Weight  = 12N

Distance  = 1m

  Work done  = 12 x 1 = 12J

For the second box;

 Weight  = 1000N

 Distance  = 30cm  = 0.3m

 Work done  = 1000 x 0.3  = 300J

The second box has a higher work done.

Answer:

what's the question

Explanation:

I don't understand the question

Answer:

0.5

Explanation:

From the question given above, the following data were obtained:

Force (F) = 50 N

Weight (W) = 100 N

Coefficient of static friction (μ) =.?

The coefficients of static friction (μ) is simply defined as the ratio of force (F) to the normal reaction (N). Mathematically, it can be expressed as:

μ = F / N

With the above formula, we can obtain the coefficient of static friction as follow:

Force (F) = 50 N

Weight (W) = 100 N

Coefficient of static friction (μ) =.?

μ = F / W

μ = 50 / 100

μ = 0.5

Thus, coefficient of static friction is 0.5

Explicación:

Dado que :

Dado:

Fuerza, F = 3500 N

Ángulo formado con la horizontal, θ, = 45 °

Los componentes de una fuerza se pueden descomponer en componentes verticales y horizontales.

El componente vertical Fy; y

El componente horizontal Fx

Fy = Fuerza * sinθ

Fy = 3500 * sin45 °

Fy = 2474,8737

El componente horizontal:

Fx = Fuerza * cosθ

Fy = 3500 * cos45 °

Fy = 2474,8737

Answer:

0

Explanation:

the forces gets cancelled off. hence when applying F=Ma, F=0 therefore a=o

The acceleration of the cart is 0m/s². Option A is correct.

According to Newton's second law of motion:

[tex]\sum F=ma[/tex]

m is the mass of the object

a is the acceleration

If a force of 25 newtons east and a force of 25  newtons, then the sum of force is expressed as:

[tex]\sum F = 25 - 25 =0N[/tex]

Get the acceleration

[tex]a=\frac{\sum F}{m} \\a=\frac{0}{5} \\a=0m/s^2[/tex]

Hence the acceleration of the cart is 0m/s²

Answer:

A valence number of 1 means that an alement will generally react to lose one electron to obtain a full outer shell.

Group two elements are assigned a valence number of 2. A valence number 2 means that a group two elements will generally react to lose two electrons to obtain a full outer shell.

Answer:

[tex]36 g/cm^{3}[/tex]

Explanation:

In order to find the density, the problem says we need to find the volume first.

Since we know that the sample of gold is a perfect cube, we know that the side lengths will all be the same. Since all the side lengths will be 3, we can take that value and cube it to find the volume.

[tex]3^{3} = 27[/tex]

Now that we know the volume is 27 cm³, we can solve find the density.

[tex]Density = \frac{Mass}{Volume}[/tex]

[tex]Density = \frac{972g}{27cm^{3} } = 36 g/cm^{3}[/tex]

Therefore, the density of the sample is 36 g/cm³.

Answer:

His first law states that every object will remain at rest or in uniform motion in a straight line unless compelled to change its state by the action of an external force. This is normally taken as the definition of inertia.

Explanation:

Answer:

It states that: If a body is at rest or moving at a constant speed in a straight line, it will remain at rest or keep moving in a straight line at constant speed unless it acted upon by a force

Answer:

The work completed is 73.5 Joule

Explanation:

Mechanical Work

Mechanical work is the amount of energy transferred by a force that moves an object by a certain distance. It's a scalar quantity, with SI units of joules.

Being  the force and  the displacement the work is calculated as:

W=F.s

The box of m=5 kg is lifted by a distance of s=1.5 m. The force applied to lift the box is equal to the weight of the box, assuming it's lifted at a constant speed, thus:

F = mg = 5 * 9,8 = 49 N

The work is:

W = 49 N * 1.5 m

W = 73.5 J

The work completed is 73.5 Joule

Answer:

C) more

Explanation:

because the amplitude of a wave is the maximum displacement of a particle from its rest position, thus, the more energy there is, the higher the particle is displaced

hope this helps, if not, please report it so that someone else can try it

The greater a wave's amplitude, the more energy the wave carries. The correct option is C.

Due to the fact that the amplitude of a wave represents the maximum displacement of a particle from its rest position, the higher the displacement of the particle, the more energy there is.

The maximum displacement or distance made by a point on a vibrating body or wave relative to its equilibrium location is known as the amplitude in physics.

The wave's deviation from its mean position is referred to as amplitude. It measures the vertical separation of the peak (also known as the crest or trough) from the mean position. The distance between the center line (or the still position) and the top or bottom of a wave's crest or trough is known as the amplitude.

Therefore, the correct option is C: more.

Answer:

Since the Kinetic energy forumla is K=(1/2)mv^2 if you double the mass the kinetic energy of the object also doubles. for example if your object has a mass of 3 and a velocity of 2 then its K.E. equals 6, if you then double its mass the kinetic energy now equals 12. A good analogy would be something like a bowling ball, if you throw a 12 pound ball at the same speed as a 6 pound ball, the force from the 12 pound ball would be exactly double to the 6 pound ball.

Answer:

Explanation:

According to Newton's law of gravitation , all objects should take same time to fall from same height , but it does not happen when we see a paper , a thermocol and a plastic paper to fall .

It happens due to air resistance . In case of paper , this is most pronounced , so it falls slowest . In case of plastic paper , the resistance is least so it falls fastest .

If we squeeze the piece of paper to make a lump so that it does not remain flat , it will fall the fastest , because in this case the air resistance on it becomes the least .

It is possible for sedimentary rocks to be converted to igneous rocks. Under conditions of high temperature and pressure, sedimentary rocks can be broken down into igneous rock by melting this rock type.

When the rock is broken down, it forms melt which when cooled and solidifies will form igneous rocks.

Sedimentary rocks are formed from the breaking down of pre-existing rocks through the action of weathering, erosion and sediment transportation. Within a basin, the sediments are compacted and lithified.

When this is subjected to intense pressure and temperature, the rock hardens and might further break down to melt.

Answer:it will take 10 hours

Explanation: The way we get this answer is if the boat travels 200 miles at 20 mph that means that every 20 miles the boat traveled an hour would pass. Using this we can see that 20 fits into 200, 10 times, meaning that the time it would take to travel would be 10 hours.

The time it will take to travel 200 miles is 10 seconds

The calculation can be done as follows

= 200/20

= 10 seconds

Hence the amount of time it will take the speed boat to travel 200 miles is 10 seconds
