Find the state of Georgia in the southeastern U.S. What can you say about the weather in this state?

Explanation:

Load (l) = 680N

Effort (E) = 500N

Length slope (l) = 12m

Height slope (h) = 8 m

Output = load * height

680 *8 = 5.44 *103 J

The Input = effort * length = 500 *12 = 6000J

the Mechanical advantage (M.A) = load effort= 600500=1.36

the Velocity ratio (V.R) =lh=128 = 1.5

the Efficiency =M.A100%V.R= 90.6%

Answer:velocity =-.65 speed=.65

Answer:

Explanation:

To determine the direction of the magnetic field in this region, we can use the right-hand rule for magnetic forces.

If we point our right thumb in the direction of the particle's velocity (in the +x direction) and our right fingers in the direction of the magnetic force (in the -y direction), then the direction of the magnetic field will be perpendicular to both the velocity and force vectors, and will be in the +z direction.

Here's a labelled diagram to help visualize this:

x

In this diagram, the particle is moving in the +x direction (out of the page) and experiences a magnetic force in the -y direction (towards the bottom of the page). Therefore, the magnetic field must be in the +z direction (upwards on the page), perpendicular to both the velocity and force vectors.

Note: This assumes that the particle is negatively charged, which means that its velocity vector points in the opposite direction to the direction of the electric field. If the particle were positively charged, the direction of the magnetic field would be in the -z direction (downwards on the page).

Answer:

The value of m = 3.735 and the value of n = 7.

Explanation:

The equation for the momentum of the train is,

                                          P = mv  

Here, m is the mass of the train and v is the speed of the train.

Substitute \(4.5 \times {10^5}{\rm{ kg}} , 8.3 \times {10^1}{\rm{ m/s}}\) for m and v respectively in above equation.

\(\begin{array}{c}\\P = \left( {4.5 \times {{10}^5}{\rm{ kg}}} \right)\left( {8.3 \times {{10}^1}{\rm{ m/s}}} \right)\\\\ = 37.35 \times {10^6}{\rm{ kg}} \cdot {\rm{m/s}}\left( {\frac{{{{10}^1}{\rm{kg}} \cdot {\rm{m/s}}}}{{10\,{\rm{kg}} \cdot {\rm{m/s}}}}} \right)\\\\ = 3.735 \times {10^7}{\rm{ kg}} \cdot {\rm{m/s}}\\\end{array}\)  

According to the scientific notation, here the value of m is 3.735 and the value of n is 7 in the final answer of the momentum.

                        The value of m = 3.735 and the value of n = 7.

Answer:

d = 0.479 m

Explanation:

Given that,

The distance light travels in  = 1.6 ns

The speed of light is \(2.998\times 10^8\ m/s\)

The speed of an object is given by distance traveled divided by time.

\(c=\dfrac{d}{t}\\\\d=ct\\\\d=2.998\times 10^8\times 1.6\times 10^{-9}\\\\=0.479\ m\)

Hence, the required distance is 0.479 m.

In the given graph, from 4.0 s to 8.0 s, the object is at rest because the speed is zero.

In the given graph we can deduce the following;

When the speed of an object is zero (0), the object is simply at rest.

Thus, we can conclude that in the given graph, from 4.0 s to 8.0 s, the object is at rest because the speed is zero.

The correct answer of a graph with shiftable lines will not require you to move both or any lines.

When the lines of a graph is shifted, the new line will have a new equation different from the original or previous line.

This means that you do not have to move the lines of the graph before getting the correct answer.

In all cases, the point of intersection of the two lines is the solution to the graph.

However, if the two lines do not intersect, then the graph does not have a solution.

So, the correct answer of a graph with shiftable lines will not require you to move both or any lines.

The resultant R of the forces exerted on the screw eye is 357.77 lb.

The definition of force in physics is: The push or pull on a massed object changes its velocity. An external force is an agent that has the power to alter the resting or moving condition of a body. It has a direction and a magnitude.

A spring balance can be used to calculate the Force. The Newton is the SI unit of force.

The gravitational  force : 3.125 N

Given

F₁ = 50 N

Required

F₂

Solution

Newton's Gravity Law:  

\(\rm F=G.\dfrac{m_1.m_2}{r^2}\)

with F = gravitational force,  

G = gravitational constant,  

m1, m2 = mass of object,  

r = distance between two objects.  

The value of m and G are the same , so :

F₁ ≈ 1/r₁²

The distance between the two is increased to four times:

r₂ = 4r₁

F₂ = 1/(4r₁)²

F₂ = 1/16r₁²

F₂ = F₁ x 1/16

F₂ = 50 : 16

F₂ = 3.125 N

While certain types of glass containers may be suitable for short-term storage of vinegar, it is generally recommended to use non-reactive materials, such as plastic or stainless steel, for long-term storage to avoid any potential chemical reactions or corrosion.

Vinegar is an acidic liquid that contains acetic acid. When vinegar comes into contact with certain types of glass, particularly those made of lead or other reactive materials, a chemical reaction can occur. This reaction can lead to the leaching of potentially harmful substances into the vinegar.

Glass containers made from specific types of glass, such as soda-lime glass, are generally safe for storing vinegar.

However, it is important to note that prolonged storage or exposure to vinegar can still cause the glass to corrode over time. This can result in the deterioration of the glass container, potentially leading to breakage or the release of glass fragments.

To avoid any potential issues, it is recommended to use containers made of non-reactive materials, such as food-grade plastic or stainless steel, for long-term storage of vinegar. These materials do not react with the acidic nature of vinegar and do not pose a risk of leaching harmful substances.

Additionally, it is important to store vinegar in a cool, dark place to maintain its quality and prevent spoilage. Exposure to light and heat can degrade the quality of vinegar over time.

The double-slit experiment, fringes are more widely spaced when illumination is with monochromatic is low frequency light

What is low frequency light?

Light waves have a frequency that is proportional to their energy: Low frequency light is less energetic than high frequency light. Gamma rays therefore have the highest energy, which contributes to their high hazard to humans, whereas radio waves have the lowest energy.

Since the letters in the word "VIBGYOR" are written in decreasing frequency sequence, we can see that Orange has the lowest frequency among the alternatives while Red generally has the lowest frequency.

Taking into account the definition of kinetic energy, the velocity of the object with a kinetic energy of 250 J and a mass of 32 kg is 3.95 m/s².

Kinetic energy is the energy possessed by a body or system due to its movement.

Kinetic energy is defined as the amount of work necessary to accelerate a body of a certain mass and in a position of rest, until it reaches a certain speed. Once the final speed is reached, the amount of kinetic energy accumulated will remain constant, that is, it will not vary, unless another force acts on the body again.

Kinetic energy is represented by the following expression:

Ec = 1/2×m×v²

Where:

In this case, you know:

Replacing in the definition of kinetic energy:

250 J = 1/2× 32 kg×v²

Solving:

250 J÷ (1/2× 32 kg) = v²

15.625 J÷kg = v²

√15.625 J÷kg = v

3.95 m/s² = v

Finally, the velocity of the object is 3.95 m/s².

If you pull with a constant force of 400 N for 0.2 meters, then the work done will be equal to 80 J.

In physics, the word "work" involves the measurement of energy transfer that takes place when an item is moved over a range by an externally applied, at least a portion of which is applied within the direction of the displacement.

The length of the path is multiplied by the element of a force acting all along the path to calculate work if the force is constant. The work W is theoretically equivalent towards the force f times the length d, or W = fd, to portray this concept.

As per the given information in the question,

Force, f = 400 N

Displacement, d = 0.2 meters

\(Work done(W)=Force(f)*Displacement(d)\)

Can animals be at the top of more than one food chain? There cannot be too many links in a single food chain because the animals at the end of the chain would not get enough food (and hence, energy) to stay alive.

Answer:

Force = 5.22 N

Explanation:

According to Newton's Second Law of motion:

\(Force = Rate\ of\ Change\ of\ Momentum\\\\Force = \frac{mv_f-mv_i}{t}\\\)

where,

m = mass of ball = 145 g = 0.145 kg

vf = final speed of ball after hit = 25 m/s

vi = initial speed of ball before hit = -  11 m/s (negative sign due to opposite direction)

t = time of contact = 1 s

Therefore,

\(Force = \frac{(0.145\ kg)(25\ m/s)-(0.145\ kg)(-11\ m/s)}{1\ s} \\\\\)

Force = 5.22 N
