Which law of motion describes squeal and oppisit forces of action and reaction

1 answer:

4 0

These two forces are called action and reaction forces and are the subject of Newton's third law of motion. Formally stated, Newton's third law is: For every action, there is an equal and opposite reaction. The statement means that in every interaction, there is a pair of forces acting on the two interacting objects.

Hope this helps! :)

1.60 kg frictionless block is attached to an ideal spring with force constant 315 N/m . Initially the spring is neither stretche

Tatiana [17]

Answer:

(a). The amplitude of the motion is 0.926 m.

(b). The block’s maximum acceleration is 182.31 m/s².

(c). The maximum force the spring exerts on the block is 291.69 N.

Explanation:

Given that,

Mass of block =1.60 kg

Force constant = 315 N/m

Speed = 13.0 m/s

(a). We need to calculate the amplitude of the motion

Using conservation of energy

$\dfrac{1}{2}mv^2=\dfrac{1}{2}kA^2$

$A^2=\dfrac{mv^2}{k}$

Put the value into the relation

$A^2=\dfrac{1.60\times13.0^2}{315}$

$A=\sqrt{0.858}$

$A=0.926\ m$

(b). We need to calculate the block’s maximum acceleration

Using formula of acceleration

$a=A\omega^2$

$a=A\times\dfrac{k}{m}$

Put the value into the formula

$a=0.926\times\dfrac{315}{1.60}$

$a=182.31\ m/s^2$

(c). We need to calculate the maximum force the spring exerts on the block

Using formula of force

$F=ma$

Put the value into the formula

$F= 1.60\times182.31$

$F=291.69\ N$

Hence, (a). The amplitude of the motion is 0.926 m.

(b). The block’s maximum acceleration is 182.31 m/s².

(c). The maximum force the spring exerts on the block is 291.69 N.

Just like the water cycle, rocks undergo changes of form in a rock cycle. A metamorphic rock can become an igneous rock, or a sedimentary rock can become a metamorphic one. Unlike the water cycle, you can’t see the process happening on a day-to-day basis. Rocks change very slowly under normal conditions, but sometimes catastrophic events like a volcanic eruption or a flood can speed up the process. So what are the three types of rocks, and how do they change into each other? Keep reading to find out!

Answer:

Explanatio

Increasing the speed of the relative motion between the coil and the magnet – If the same coil of wire passed through the same magnetic field but its speed or velocity is increased, the wire will cut the lines of flux at a faster rate so more induced emf would be produced. 3)n:

If a 0.200-kilogram ball sits on a shelf 2.00 meters from the floor, how much mechanical energy (me) does it possess? More than

iogann1982 [59]

Answer:

Mechanical energy = 3.92 J

exactly 3.92 j

Explanation:

As we know that mechanical energy is sum of kinetic energy and potential energy of the system

so here we can say that mechanical energy is sum of kinetic energy of ball and its potential energy

Since ball is at rest so kinetic energy of the ball must be ZERO

Now for potential energy we know that

$U = mgh$

now we know

m = 0.2 kg

h = 2 m

now for potential ene'rgy

$U = (0.20)(9.8)(2)$

$U = 3.92 J$

so mechanical energy is given as

Mechanical Energy = 3.92 + 0 = 3.92 J

Which of the following metals reacts with oxygen and acids but is not very reactive with water?

Lina20 [59]

Calcium is reactive with oxygen, acid, and water. Copper is not reactive with water as well as with acids, whereas magnesium is reactive with acid but reactive with water.

<h3>What is a Chemical Reaction?</h3>

One or more chemicals (the reactants) are changed into one or more other compounds during a chemical reaction (the products).Substances are made up of chemical components or chemical elements.

Each calcium atom donates a pair of electrons to an oxygen atom during the interaction between calcium and oxygen to create calcium oxide.

When calcium reacts with hydrochloric acid, it releases bubbles of hydrogen gas, and when large chunks of calcium react with hydrochloric acid, it releases hydrogen gas. Calcium in reaction with water produces calcium hydroxide and hydrogen gas

When magnesium and oxygen interact, they produce light that is so strong that it temporarily impairs your vision. Magnesium burns so brilliantly because it produces a lot of heat while doing so.

Magnesium reacts with hot water or water vapor to produce hydrogen gas and magnesium hydroxide.

Acid does not react with copper. Metals such as lead, copper, silver, and gold do not react with water at all.
