Answer:

The net force on the box is 30 N to the right.

Explanation:

To find the net force on the box, we must add all of the forces together. In order to do this successfully, we must establish a positive and a negative direction. Let’s say that the positive direction is towards the right and the negative direction is towards the left.

Knowing this, we can set up the following equation:

Net force = F1 + F2

Now we can substitute in our known values for the forces given in the problem.

Net force = 60 N + (-30 N)

If we simplify and solve, we get

Net force = 60-30 = 30 N

Since we established the right as the positive direction, we know that the answer is 30 N to the right. If we think about this problem conceptually, this answer makes sense because the 30 N force to the left cancels out 30 N of the force towards the right, because they are acting in opposite directions.

Hope this helps!

Answer: A. Object A will have a positive charge.

Explanation: If the number of protons and electrons are the same, their net charges cancel each other out, and you have a neutral charge. If electrons are transferred to another object, the amount of positive charge will outweigh the amount of negative charge. As a result, you are left with an overall positive charge in object A. Meanwhile, object B is now negative.

Final answer:

When electrons are transferred from object A to object B, object A will become positively charged (option A) due to the loss of negatively charged electrons. This makes the answer A. Object A will have a positive charge.

Explanation:

If some electrons are transferred from object A to object B, the correct answer is A. Object A will have a positive charge. This is because electrons have a negative charge, and removing them from an object leaves that object with an excess of positive charge in the form of protons (which are positively charged and present in every atom). Object B, receiving the electrons, will become negatively charged since it gains additional negative charges.

DescriptionA storm surge, storm flood, tidal surge or storm tide is a coastal flood or tsunami-like phenomenon of rising water commonly associated with low pressure weather systems, the severity of which is affected by the shallowness and orientation of the water body relative to storm path, as well as the timing of tides.

A wall of water that is pushed ashore is a storm surge. So, the correct option is A.

A coastal flood or tsunami-like event of rising water known as a storm surge, storm flood, tidal surge, or storm tide is frequently linked to low-pressure weather systems like cyclones. It excludes waves and is calculated as the rise in the water level just above typical tidal level.

Extreme coastal as well as interior flooding may be the result of the seawater's pulse when it reaches the coast. Storm surge can sometimes be much more destructive than the thunderstorms that produce it.

An anomalous increase in water caused by a storm that is higher than the expected astronomical tides is known as a storm surge. Storm tide, which is referred to as the increase in water level brought on by a storm surge and an astronomical tide, shouldn't be confused with storm surge.

Therefore, the correct option is A.

Answer:

the earth would be a different place, for example there wouldnt be anymore volcanic eruptions

Explanation:

when the earth plates stops moving is the source to everything, the ground would shake, waves would stop ect

There would be no new island formations when oceanic plates stop moving.

Explanation:

The oceanic plate or the tectonic plate movement determines the several activity of land and ocean which keep making the life possible. As the plate movement stop, volcanic eruption will be stopped, sea floor will not spread further, every activity below ground will cease.

The pressure increases inside the core and so does the erosion. The continent will be lost with all its life on the land. Oceanic life will survive more but may freeze the planet to die.  

Answer:

"Wave 3 resulted from constructive interference and Wave 4 resulted from destructive interference."

Explanation:

Constructive Interference:

When two waves meet in such a way that their crests line up together, then it's called constructive interference. The resulting wave has a higher amplitude.

Destructive Interference:

In destructive interference, the crest of one wave meets the trough of another, and the result is a lower total amplitude.

The amplitude of Wave 3 is higher than both the Waves, 1 & 2, so it must be a result of constructive interference.

The amplitude of Wave 4 is less than both the Waves, 1 & 2, so it must be a result of destructive interference.

Is halved. A 6Ω resistor connected to a voltage source which voltage is decreased from 12V to 6V the current passing through the resistor is halved.

The key to solve this problem is applying Ohm's Law V = R I, clearing I from the equation, we obtain I = V/R. Then, the current is directly proportional to the voltage and inversely proportional to the resistance.

V = 12V and R = 6Ω

I = 12V/6Ω = 2A

V = 6V and R = 6Ω

V = 6V/6Ω = 1A

As we can see the current is halved if the voltage descreased from 12V to 6V

The correct option is

(c) is halved.

Given a 6Ω resistor and the voltage is decreased from 12V to 6V

Ohm's Law:

Ohm's law states that the current (I) is directly proportional to the voltage (V) and inversely proportional to the resistance (R). That is

V= I/R

here, according to the question

initially, V = 12V and R = 6Ω

so I = 12V/6Ω = 2A

Finally

V = 6V and R = 6Ω

I' = 6V/6Ω = 1A

so we see that

2I' = I

I' = I/2

Hence, the current is halved.

The most common types of precipitation are:

- rain

- snow

- hale

The rain comes in liquid form. In order for the rain to occur, the temperature in the upper parts of the troposphere should not be too low, thus the condensation of the water vapor can only go from gaseous to liquid form. The rain occurs in the lower latitudes, as well as in the mid-latitudes mostly from spring to autumn.

The snow occurs in the higher latitudes and in the mid-latitudes during winter. In order for the snow to form, the temperatures in the upper parts of the troposphere should be below the freezing point, so the water vapor crystallizes into small ice crystals.

The hale occurs in the warmer period in the mid-latitudes, and occasionally in the lower latitudes. The hale is formed when during the condensation of the water vapor into liquid form, the air mass encounters much lower temperatures below the freezing point. This results in the formation of large crystals that fall on the surface in the form of frozen, circular-shaped pieces.

Answer:

Maximum compression of the spring: [tex]\rm 0.423\; m[/tex].

Explanation:

Let [tex]x[/tex] be the maximum compression, in meters, of the spring.

What's the initial kinetic energy of this block?

What's the final kinetic energy of this block?

Let the initial height of the block be zero.

The height of the block will be [tex]\rm -1.8\;m[/tex] by the time it reaches the top of the spring. However, the height of the block will become even more negative as the spring compresses. If the maximum compression of the spring is [tex]x[/tex] meters, the height of the block will be [tex]-(1.8 + x)[/tex] meters by the time the spring reaches its maximum compression.

The change in the height of the block will thus be [tex]-(1.8 + x)\;\mathrm{m}[/tex] relative to the initial position of the block. The change in the block's potential energy due to gravity will be:

[tex]\Delta \mathrm{GPE} = m\cdot g\cdot \Delta h = 6\times 9.8 \times (-(1.8 + x)) = -105.948- 58.86\;x[/tex].

The mechanical energy of an object is the sum of its kinetic energy and its potential energy. What will be the change in the mechanical energy of the block?

[tex]\text{Change in Mechanical Energy} \\ = \text{Change in KE} + \text{Change in PE} \\ = (0 - 48) + ((-105.948- 58.86\;x) - 0)\\ = (-153.948 - 58.86\;x)\; \text{J}[/tex].

The block has lost [tex](153.948 + 58.86\;x)\; \text{J}[/tex] of energy as it travels from its initial position to the place where the spring is most compressed. Energy conserves. Those energies are transferred to the spring. Assume that there's no energy loss in this process. All those [tex](153.948+ 58.86\;x)\; \text{J}[/tex] would have become the elastic potential energy of the spring.

On the other hand, it is assumed that the spring is compressed by a distance of [tex]x[/tex] meters. By Hooke's Law, the elastic potential energy of the spring will be:

[tex]\displaystyle \text{Elastic Potential Energy} = \frac{1}{2} \; k\cdot x^{2} = \frac{1}{2}\times 2000 \times x^{2} = 1000\; x^{2}\;\text{J}[/tex].

There are thus two expressions for the Elastic Potential Energy of the spring:

The two expression shall be equivalent. Equate the two expressions and solve for the compression of the spring, [tex]x[/tex].

[tex]153.948+ 58.86\;x = 1000\; x^{2}[/tex].

[tex]1000\; x^{2}- 58.86\;x - 153.948 = 0[/tex].

[tex]\displaystyle x_{1} = \frac{-(-58.86) +\sqrt{(-58.86)^{2} - 4\times 1000 \times (-153.948)}}{2\times 1000} = \rm 0.423[/tex].

[tex]\displaystyle x_{2} = \frac{-(-58.86) +\sqrt{(-58.86)^{2} - 4\times 1000 \times (-153.948)}}{2\times 1000} = -0.364[/tex].

Consider the expression for the height of the block when it is at the top of the spring and when the spring reaches maximum compression:

The maximum compression of the spring will be 0.423 meters.

Answer:

Therefore, gravity does 588.6 Joules of work in causing the 6 kg hammer to fall 10 meters.

Explanation:

Gravity does work by exerting a force on the hammer over a certain distance. We can calculate this work using the formula:

Work = Force x Distance (where force is parallel to the direction of movement)

In this scenario:

Force = Gravitational force acting on the hammer (Weight of the hammer)

Distance = Height fallen

Force:

We can calculate the gravitational force (weight) using the formula: Weight = Mass x Gravity

Mass of the hammer (m) = 6 kg

Gravity (acceleration due to gravity) = 9.81 m/s² (approximately)

Weight = 6 kg * 9.81 m/s² = 58.86 N (Newtons)

Distance:

Distance (d) = 10 m

Work done by gravity:

Work = Force x Distance = 58.86 N * 10 m = 588.6 Joules

Therefore, gravity does 588.6 Joules of work in causing the 6 kg hammer to fall 10 meters.

Density = (mass) / (volume)

Density = (20 g) / (5 cm³)

Density = 4 g/cm³ .

The density of the substance is greater than the density of water. A lump of the substance will sink in water, unless the lump is formed into a shape that displaces 20 cm³ of water or more, such as a tiny boat shape.

Answer:

100 m/s²

Explanation:

First, convert to SI units:

50 g = 0.050 kg

Now plug into the formula:

F = ma

5 N = (0.050 kg) a

a = 100 m/s²

A force of 5 N accelerates an object. The object’s mass is 50 g. Then acceleration of the object is  100 m/s².

The formula linking force, mass, and acceleration is given by

F = ma,

Where F = the force applied to the object,

m = the mass of the object,

and a =the resulting acceleration.

In this case, the force is 5 N and the mass is 50 g, or 0.05 kg (remember to convert grams to kilograms).

Now, we can solve for the acceleration using:

a = F/m

a = 5 N / 0.05 kg

a = 100 m/s²

So the acceleration of the object is 100 m/s².
