A force of 5 N accelerates an object. The objects mass is 50 G. What is the acceleration of the object? (Formula: F=ma)

Answer:

-5.3 m

Explanation:

Consider north to be the positive direction, and south to be the negative direction. Adding up the displacements gives

(+2.1m) + (-7.4m) = 2.1 - 7.4m = -5.3m (southward direction)

This makes sense because if he travels 2.1 m north, then 7.4 south, he would end up south of where he started because he passed 2.1 m and went further

There are several reasons why it is impossible for nuclear energy to completely replace oil and gas in the future. First and foremost, the infrastructure required to generate nuclear energy is highly expensive and complex.

Additionally, nuclear reactors require a significant amount of time and resources to construct, and safety protocols must be strictly enforced to prevent catastrophic accidents. Furthermore, nuclear waste management is a major challenge that is still being addressed by the industry. Additionally, nuclear energy is not a renewable source of energy like solar and wind energy, which means that nuclear fuel is finite and will eventually run out. Even if all of the world's oil and gas reserves were depleted, nuclear energy would still not be a viable option for replacing them due to these limitations. Overall, while nuclear energy can provide a substantial amount of energy and play a role in reducing carbon emissions, it cannot entirely replace oil and gas as a source of energy in the future.

The elastic potential energy stored is 0.9375 J.

The elastic potential energy stored in a spring can be calculated using the following formula:

Elastic potential energy = 0.5 × k × x²

where:

k is the spring constant

x is the distance the spring is compressed or stretched

In this case, the spring constant is given as 12.5 N/mm and the compression is 0.15 mm. Plugging these values into the formula, we get the following:

Elastic potential energy = 0.5 × 12.5 N/mm × (0.15 mm)²

= 0.9375 J

Therefore, the elastic potential energy stored is 0.9375 J.

The elastic potential energy stored in the abductin pad is used to open the shell when the muscles relax. The muscles close the shell by contracting, which compresses the pad. When the muscles relax, the pad expands, pushing the shell open. The energy to do this comes from the elastic potential energy that was stored in the pad when it was compressed.

Taking into account the Universal Law of Gravitation, the force of gravity between them is quadrupled the mass of both of the objects is doubled.

The Universal Law of Gravitation establishes that bodies, by the simple fact of having mass, experience a force of attraction towards other bodies with mass, called gravitational force.

The Universal Law of Gravitation states that the gravitational force between two bodies is directly proportional to the product of their masses and inversely proportional to the square of the distance that separates them.

Mathematically it is expressed as follows:

\(F=G\frac{Mm}{d^{2} }\)

where:

Since the gravitational force is directly proportional to the mass of both interacting objects, more massive objects will attract each other with a greater gravitational force. So as the mass of either object increases, the force of gravitational attraction between them also increases.

In this case, the mass of the objects is doubled. Then, the force of gravity between them is quadrupled.

In summary, the force of gravity between them is quadrupled the mass of both of the objects is doubled.

The proposed system is not sound from a thermodynamic point of view.

The proposed system to cool a house in the summer by compressing the regular outdoor air, allowing it to cool back to the outdoor temperature, passing it through a turbine, and discharging the cold air leaving the turbine into the house is not sound from a thermodynamic point of view. This is because the system violates the Second Law of Thermodynamics.The Second Law of Thermodynamics states that heat flows naturally from a hotter body to a cooler body but not the other way around without external help.

The proposed system involves compressing the air and then allowing it to cool back to the outdoor temperature. This results in a transfer of heat from a cooler body (the outdoor air) to a hotter body (the compressed air). This violates the Second Law of Thermodynamics, which states that heat cannot flow naturally from a cooler body to a hotter body without external help. Therefore, the proposed system is not sound from a thermodynamic point of view.

Answer:

1530 m/s

Explanation:

Given that :

Speed = distance / time

Travel time take = 0.2 s

Distance covered = 306 metres

The speed of sound in the material :

Speed = distance / time = 306 m / 0.2

Speed = 1530 m/s

(a) The tangential speed of the rim of the disk is found to be 48.3 m/s and (b) On increasing the operating speed, the period of rotation of the disk is now  0.0314 seconds.

(a) To determine the tangential speed of the rim of the disk, we can use the formula,

v = ωr, tangential speed is v, ω is the angular velocity is ω, and radius of the disk is r. Given ω = (2.10) 10⁴ rad/s and r = 2.30 mm = 0.00230 m, we can calculate,

v = (2.10(10⁴)rad/s)(0.00230m)

v ≈ 48.3 m/s

Therefore, the tangential speed of the rim of the disk is approximately 48.3 m/s.

(b) To find the period of rotation, we can use the formula,

T = 2π / ω, period of rotation is T and angular velocity is ω.

Given v = 255 m/s, we can rearrange the formula to solve for ω,

ω = v / r

Substituting the values, we have,

ω = 255 m/s / 0.00230 m

ω ≈ 111086.96 rad/s

Now we can calculate the period,

T = 2π / ω

T = 2π / (111086.96 rad/s)

T ≈ 0.0314 seconds

So, the period of rotation is now 0.0314 seconds.

The extra cost of fuel for driving 83 mph instead of 73 mph is $3.7671.

The speed of your automobile has a huge effect on fuel consumption. Traveling at 65 miles per hour (mph) instead of 55mph can consume almost 20% more fuel. As a general rule, for every mile per hour over 55 , you lose 2% in fuel economy.

If you take a 400-mile trip and your average speed is 83mph rather than the posted speed limit of 73mph, then the extra cost of the fuel is calculated as:

* **Fuel consumption at 83 mph:** 30 mpg * (1 - 2% * (83 - 55)) = 27.6 mpg

* **Fuel consumption at 73 mph:** 30 mpg * (1 - 2% * (73 - 55)) = 29 mpg

* **Extra fuel used:** 400 miles / 27.6 mpg - 400 miles / 29 mpg = 2.4 gallons

The equilibrium constant for any reversible chemical system expresses the ratio of the concentrations (or partial pressures) of the products to the concentrations (or partial pressures) of the reactants at equilibrium.

The equilibrium constant, denoted as K, is a fundamental concept in chemical equilibrium that quantifies the relative amounts of reactants and products at equilibrium. It expresses the ratio of the concentrations (or partial pressures) of the products to the concentrations (or partial pressures) of the reactants at equilibrium.

The equilibrium constant is specific to each chemical reaction and is determined by the stoichiometry of the reaction. It provides valuable information about the position of equilibrium and the extent of the reaction. A high equilibrium constant (K > 1) indicates that the products are favored at equilibrium, while a low equilibrium constant (K < 1) indicates that the reactants are favored.

The speed of an electron when its kinetic energy is 8 times its rest energy is approximately 0.93c, or 93% of the speed of light.

The kinetic energy of an object is given by 1/2mv^2, where m is the mass of the object and v is its velocity. The rest energy of an electron is approximately 0.511 MeV/c^2. Thus, when the kinetic energy of the electron is 8 times its rest energy, we have:
1/2mv^2 = 8(0.511 MeV/c^2)
Solving for v, we get:
v = sqrt[(2*8*0.511 MeV/c^2)/m]
The mass of an electron is approximately 9.11 x 10^-31 kg. Plugging in the values, we get:
v = sqrt[(8.176 MeV)/9.11 x 10^-31 kg]
v ≈ 2.79 x 10^8 m/s = 0.93c

Answer:

The given statement is false.

Explanation:

Answer:

Seafloor spreading occurs because earthquakes break apart the ocean floor.

Seafloor spreading is a geologic process where there is a gradual addition of new oceanic crust in the ocean floor through a volcanic activity while moving the older rocks away from the mid-oceanic ridge. The mid-ocean ridge is where the seafloor spreading occurs, in which tectonic plates—large slabs of Earth’s Lithosphere—split apart from each other.

Seafloor spreading was proposed by an American geophysicist, Harry H. Hess in 1960. By the use of the sonar, Hess was able to map the ocean floor and discovered the mid-Atlantic ridge (mid-ocean ridge). He also found out that the temperature near to the mid-Atlantic ridge was warmer than the surface away from it. He believed that the high temperature was due to the magma that leaked out from the ridge. The Continental Drift Theory of Alfred Wegener in 1912 is supported by this hypothesis on the shift position of the earth’s surface.

The mid-ocean ridge is the region where new oceanic crust is created. The oceanic crust is composed of rocks that move away from the ridge as new crust is being formed. The formation of the new crust is due to the rising of the molten material (magma) from the mantle by convection current. When the molten magma reaches the oceanic crust, it cools and pushes away the existing rocks from the ridge equally in both directions.

A younger oceanic crust is then formed, causing the spread of the ocean floor. The new rock is dense but not as dense as the old rock that moves away from the ridge. As the rock moves, further, it becomes colder and denser until it reaches an ocean trench or continues spreading.

It is believed that the successive movement of the rocks from the ridge progressively increases the ocean depth and have greater depths in the ocean trenches. Seafloor spreading leads to the renewal of the ocean floor in every 200 million years, a period of time for building a mid-ocean ridge, moving away across the ocean and subduction into a trench.
