Answer:

If you double the force, you double the acceleration, but if you double the mass, you cut the acceleration in half.

Explanation:

you can double the net force

Answer:

4th one

Explanation:

Answer: Well it's not sinking. It is also not flooring or floating. so my guess it must be rising up.

Explanation: When something is impacted, the pressure of the force of energy is released and lands directly on a other object. So what does Jell-O  do when you shake it? It wobbles right? what happens when you put your hand in a bucket of water?  It makes the water rise up. So That's why I think it is rising up.

Answer:

Rising up because the weight of the object depends on the water and mass

Explanation:

The action and reaction law allows us to find that the reaction force, the weight of the cylinder, is:

Newton's third law or action and reaction law, establishes that if two bodies interact with each other the force that one applies to the other, is equal in magnitude to the force of the second on the first but in the opposite direction, that is, all forces act in pairs one in each body that interact.

Forces with these characteristics are called action and reaction.

In this case we have a hanging cylinder, with the cylinder it has mass so the weight is 12 N it acts on the table in a downward direction, let's say this is the action force.

In response to this force, the table exerts a force on the cylinder of equal magnitude but in the opposite direction, which is why it is directed upwards.

let's analyze the force diagram

In conclusion using theaction and reaction law we find that the answer for reaction force is:

Given :

Pilot sits 2.19 m from the center of rotation.

Horizontal centripetal acceleration is 65.8 m/s².

To Find :

Solution :

We know, centripetal acceleration is given by :

[tex]a = \omega^2 r\\\\\omega = \sqrt{\dfrac{a }{r}}\\\\\omega = \sqrt{\dfrac{65.8 }{2.19}}\\\\\omega = 5.48\ s^{-1}[/tex]

Answer:

[tex]x = 12.027N[/tex] and [tex]y = 8.964N[/tex]

Explanation:

The first sentence of this question is not explanatory enough. However, I'll assume the force to be 15N

[tex]Force = 15N[/tex]

[tex]\theta = 36.7[/tex] to the horizontal

Required

Solve for the x and y components

Since the given angle is to the horizontal, the x and y coordinates are calculated using the following illustrations.

[tex]Sin\theta = \frac{y}{Force}[/tex] ---- y component

[tex]Cos\theta = \frac{x}{Force}[/tex] ---- x component

Calculating the y component.

Substitute 15 for Force and 36.7 for [tex]\theta[/tex]

[tex]Sin\theta = \frac{y}{Force}[/tex] becomes

[tex]Sin(36.7) = \frac{y}{15}[/tex]

Make y the subject

[tex]y = 15 * Sin(36.7)[/tex]

[tex]y = 15 * 0.5976[/tex]

[tex]y = 8.964N[/tex]

Calculating the x component.

Substitute 15 for Force and 36.7 for [tex]\theta[/tex]

[tex]Cos\theta = \frac{x}{Force}[/tex] becomes

[tex]Cos(36.7) = \frac{x}{15}[/tex]

Make y the subject

[tex]x = 15 * Cos(36.7)[/tex]

[tex]x = 15 * 0.8018[/tex]

[tex]x = 12.027N[/tex]

Hence, the x and y components of the force are: 8.964N and 12.027N respectively.

Answer:

ball b has the greater mass.

Explanation:

b only moved because a bumped into it. if a bounced back, it had less mass and b moved slowly.

Options are;

A: measuring cylinder, metre rule

B: measuring cylinder, stopwatch

C: metre rule, balance

D: metre rule, stopwatch

Answer:

A: measuring cylinder, metre rule

Explanation:

Usually, when measuring volume of a small material, we make use of a piece of laboratory apparatus known as measuring cylinder which is also known as graduated cylinder.

Since it is a graduated cylinder, it means we will make use of metre rule.

Thus, the correct option is option A.

The apparatus which can be used to determine the volume of a small block of unknown material is: measuring cylinder; meter rule.

A measuring cylinder can be defined as a graduated cylinder that is typically designed and developed for the measurement of the volume of an irregularly shaped piece of object or a small block of unknown material.

Similarly, a meter rule refers to an apparatus that is used for the measurement of the length of an object.

Explanation:

Gravitational potential energy is the type of energy that is stored in the gravitational field. In other words, the gravitational potential energy as the energy that a body possesses due to the fact of being under the action of gravity, that is, the energy associated with an object subjected to force, weight, and weight is called gravitational potential energy. that is at a certain height with respect to a reference level.

The greater the weight of a body, the greater the gravitational potential energy and, considering the effect of this variable together with that of the height h at which the object is, the gravitational potential energy is:

 Ep = m*g*h

In this case:

Replacing:

1,000,000 J=4.536 kg* 9.81 [tex]\frac{m}{s^{2} }[/tex] *h

Solving:

[tex]h=\frac{1,000,000 J}{4.536 kg*9.81\frac{m}{s^{2} } }[/tex]

h= 22,472.84 m

The height is 22,472.84 m

Answer:

Pressure on the narrow piston = 3100 [tex]N/m^2[/tex]

The wider piston can lift the weight up-to 6200 N

Explanation:

Given that the area of the narrow piston = 0.2 [tex]m^2[/tex]

Applied force on the narrow piston, [tex]F_{in}[/tex]= 620 N

Area of the larger piston  = 2.0 [tex]m^2[/tex].

As pressure = force/ area,

So. pressure exerted on the narrow piston, [tex]P= 620/0.2=3100 N/m^2[/tex]

There is liquid in between the narrow piston and the larger piston and according to Pascal's law, the pressure inside any liquid is uniformly distributed.

As the narrow piston is applying the pressure on the liquid which is equal to the external pressure applied on the narrow piston, i.e 3100 [tex]N/m^2[/tex].

So, the uniformly distributed pressure in the fluid is 3100 [tex]N/m^2[/tex].

Now, the liquids apply pressure on the larger piston,

as force = Area x pressure, so the applied on the larger piston, [tex]F_{out}[/tex], by the liquid is

[tex]F_{out} = 3100\times2=6200[/tex] N

Hence, the wider piston can lift the weight up-to 6200 N.

A chemical compound is a combination of two or more either similar or dissimilar chemical elements, for example, H₂O is a chemical compound made up of two oxygen atoms and a single hydrogen atom.

These chemical compounds are formed because of different types of bonds between the constituent's elements, the chemical bonds are mainly ionic bonds, covalent bonds,s, and hydrogen bonds.

Carbon is stored in leaves in various forms, such as sugar. When leaves decay, they lose mass.

The carbon is converted into carbon dioxide and released into the atmosphere is the sentence that explains what happens to the carbon that is stored in leaves when they decay.

Thus, the carbon is converted into carbon dioxide and released into the atmosphere. the correct answer is option D.

Answer:

E_{k2}=2660 [J] kinetic energy.

Explanation:

The energy in the initial state i.e. when the rollercoaster is at the top is equal to the energy in the final state i.e. when it is at the bottom of the hill.

These states can be represented by means of the second equation.

[tex]E_{k1}+E_{p1}=E_{k2}\\160 + 2500 = E_{k2}\\E_{k2}=2660 [J][/tex]

Since the rollercoaster is located in the bottom of the hill where the potential energy level is zero, therefore there is only kinetic energy in the second state.
