Answer:

acceleration is the rate of change of the velocity of an object with respect to time. Accelerations are vector quantities. The orientation of an object's acceleration is given by the orientation of the net force acting on that object.

Explanation:

Calculating acceleration involves dividing velocity by time — or in terms of SI units, dividing the meter per second [m/s] by the second [s]. Dividing distance by time twice is the same as dividing distance by the square of time. Thus the SI unit of acceleration is the meter per second squared .

A surface low-pressure center is generally associated with a trough on an upper level isobaric chart.

A constant pressure chart, sometimes referred to as an upper-level isobaric chart, shows the distribution of atmospheric pressure at a particular height in the atmosphere, usually above the surface. Isobars, or lines of equal pressure, are displayed on this graph to show the pressure distribution at that level.

When we have a surface low-pressure centre, it denotes a region with relatively lower surface pressure than the surrounding areas. This surface low-pressure system often corresponds to a trough on the upper-level isobaric chart in terms of the vertical structure of the atmosphere.

On an upper-level chart, a trough is an area with relatively lower heights or pressure. The contour lines that reflect the height or pressure field have a curvature or a dip that defines it. The contour lines have a dip in them, which indicates a surface low-pressure system beneath.

Answer:

I would say there is friction against the floor, air resistance, and gravity.

Explanation:

The contact force acting on the toy is the frictional force, and the non-contact force acting on the toy is the gravitational force.

According to the question, a toy train is being pulled by a string along the floor.

The gravitational force acting on the toy train is the weight of the toy train, which is a non-contact force given by:

F  = mg

where m is the mass of the toy, and g is the acceleration due to gravity.

Now, the floor will exert a normal force against the toy, equal to the weight of the toy. Let the normal force be N.

Since the toy is in contact with the floor, there is a frictional force acting against the motion of the toy trains, which is a contact force and is given by:

f  = μN = μmg

where μ is the coefficient of friction between the toy and the floor.

The velocity to time graph of the robots can be used to calculate the displacement and distance traveled by the robot.

6) The magnitude of the displacement of the robot for the entire time interval shown is (ii) greater in Case B

7) The rank of the distance traveled during the intervals is as follows;

\(\begin{vmatrix}D| &A | &C | &B | &E| &F \\\end{vmatrix}\)

A velocity time graph describes the changes in the motion of a straight moving object

6) The displacement is given by the area under the velocity time graph.

The area is obtained by drawing a vertical line at the tip of the graph of the velocity to time of each of the robots

The area of a triangle = 0.5 × Base length × Height

The time interval in Case A is the same as the time interval in Case B which is taken as t

The time at which the velocity of the robot is 0 in figure (i) is approximately 0.5·t

The initial velocity in Case A = -v

The final velocity = v

The area under the curve in Case A, which gives the displacement is therefore;

Displacement in Case (A) = 0.5 × 0.5·t × (-v) + 0.5 × 0.5·t × (v) = 0

The magnitude of the initial velocity of the robot in Case B is half the magnitude of the final velocity of the robot

Similarly, the time at which the velocity of the robot in Case B is 0 is a third of the total time of motion

The displacement of the robot in Case B is therefore;

Displacement = 0.5 × (1/3)·t × (0.5·v) + 0.5 × (2/3)·t × (-v) = -0.25·v·t

The magnitude of the displacement in Case B = |-0.25·v·t| = 0.25·v·t > 0

The magnitude of the displacement in Case B is > The magnitude of the displacement in Case A

The correct option is therefore (ii) greater in Case B

7) The distance traveled is given by the area bounded by the curve as follows;

A. Shape of region bounded by the graph = Rectangle

Initial velocity = Constant = -1 unit

Time of travel = 5 unit

Area = -1 × 5 = -5 units

B. Shape of graph = Triangle

Initial velocity = 1.5 units

The final velocity = 0

Change in velocity = 1.5 - 0 = 1.5

The time = 5 unit

Area = 0.5 × 5 × 1.5 = 3.75

The distance = 3.75 units

C. Starting velocity = -1.7 units

The final velocity = 0

Change in velocity = -1.7

Time = 5 units

Distance ≈ 0.5 × 5 × -1.7 = -4.25

D. Shape of graph = Rectangle

Initial velocity ≈ 1.7 units (Constant)

Time = 5 units

Distance = 5 × 1.7 = 8.5

E. Shape of graph = Two congruent triangles

Initial velocity = -1 unit

Time it takes to increase to a velocity of 0 = 2.5·t

Final velocity = 1 unit

Time it takes to increase to from a velocity of 0 to a velocity of 1 = 2.5 units

Distance = Sum of the area of the two triangles

Displacement = 0.5 × 2.5 × -1 + 0.5 × 2.5 × 1 = 0

Distance = 0.5 × 2.5 × 1 + 0.5 × 2.5 × 1 = 2.5

F. Shape of area bounded by the graph = Positive triangle

Height of the triangle = 1 unit

Base length of the triangle = 5 units

Area of the triangle = Distance = 0.5 × 5 × 1 = 2.5

The rank of the distance travelled during the intervals is therefore;

D(8.5), A(-5), C(-4.25), B(3.75), E(2.5), F(2.5)

The distance is a measure of the motion of the robot such that the forward and backward motion are added together

According to the law of conservation of momentum, sum of the momenta of the bodies before collision is equal to the sum of their momenta after collision.

After their collision, the two bodies will move with a common velocity. The elastic collision as the name suggests, the collision is very elastic and there is no net energy loss in it and the bodies continue to move in same direction.

Here, a massive mass collides with a light mass which is at rest.

From the formula m₁v₁ = m₂v₂ we can know the speed after collision.

Once the massive mass collides with the lighter mass, the lighter mass which was until then at rest, will start moving (since it is elastic collision) and acquire the velocity of the massive mass.

These will move in the same direction. Due to elastic collision, the speed of massive mass will be unchanged (neglecting friction) and the lighter mass will gain a velocity v.

The notch sensitivity and fatigue stress concentration factors for the bar are calculated to determine the mean and alternating stresses and find the fatigue strength for different cycles.

To calculate the notch sensitivity and fatigue stress concentration factors, we need to consider the presence of the 10 mm hole in the center of the 30 mm side of the bar. The notch sensitivity factor quantifies the effect of the hole on the stress concentration, while the fatigue stress concentration factor determines the increase in stress due to cyclic loading.

The mean stress (σm) is the average of the minimum (F_min) and maximum (F_max) axial loads applied to the bar. The alternating stress (σa) is half the difference between F_max and F_min.

The fatigue strength for a certain number of cycles is determined by applying the appropriate factors to the ultimate tensile strength (S_Ut) or yield strength (S_y) of the material. The fatigue strength is typically given for a specified number of cycles, such as 100, 10,000, 100,000, or 1,000,000 cycles. The fatigue strength for infinite life refers to the stress level below which the material can withstand an unlimited number of cycles without failure.

To provide accurate values for the notch sensitivity, fatigue stress concentration factors, mean and alternating stresses, and fatigue strength for the specified number of cycles, further calculations and data specific to the material properties and geometry of the bar are required.

The star's luminosity rises above its previous level. Because it is so cool, the surface will be red, and it will be much farther away from the center than it was during the earlier stages of star evolution. Despite its lower surface temperature, the red giant has a large surface area, which makes it very luminous.

The speed of a tide wave as a free wave on the surface is determined by the depth of the water. This is known as the wave speed-depth relationship.

In general, the speed of a wave is directly proportional to the square root of the water depth. So, as the water depth increases, the wave speed also increases. Conversely, as the water depth decreases, the wave speed decreases.

This relationship can be understood using the equation:

Wave speed = √(g * h)

where:
- Wave speed is the speed of the wave,
- g is the acceleration due to gravity (approximately 9.8 m/s²),
- h is the depth of the water.

For example, let's consider two scenarios:

If the water depth is shallow (e.g., 1 meter), the wave speed will be relatively slow. This is because the depth is small, and the gravitational force has a greater influence on the wave speed.

On the other hand, if the water depth is deep (e.g., 10 meters), the wave speed will be relatively fast. This is because the depth is large, and the gravitational force has a smaller impact on the wave speed.

The speed of a tide wave as a free wave on the surface is determined by the depth of the water. The wave speed is directly proportional to the square root of the water depth.

To solve this problem, we can consider the bucket and water as a combined system and analyze the effects of the leak on the period of oscillation.

Part A:

When the bucket is half full, the total mass of the system is the sum of the mass of the bucket and half of the water. The total mass is:

m_total = m_bucket + (1/2)m_water = 2.50 kg + (1/2)(12.0 kg) = 8.50 kg

The period of oscillation of a mass-spring system is given by:

T = 2π√(m_total / k)

Substituting the given values, we have:

T = 2π√(8.50 kg / 450 N/m) ≈ 1.053 s

Part B:

To find the rate at which the period is changing with respect to time, we need to differentiate the period equation with respect to time (t):

dT/dt = (d/dt) [2π√(m_total / k)]

The rate at which the mass is changing with respect to time is given by the rate of water leaking, which is 2.00 g/s. Since 1 kg = 1000 g, the rate of mass change is 0.002 kg/s.

Differentiating the period equation and substituting the values, we have:

dT/dt = (d/dt) [2π√((m_bucket + m_water) / k)]

       = (d/dt) [2π√((2.50 kg + 12.0 kg - 0.002 kg·t) / k)]

Part C:

To determine whether the period is getting longer or shorter, we need to examine the sign of dT/dt. Since the term (2.50 kg + 12.0 kg - 0.002 kg·t) is decreasing with time (t), the value of dT/dt is negative. This indicates that the period is getting shorter as the water leaks out.

Part D:

The shortest period this system can have occurs when the bucket is empty, meaning there is no water inside. In this case, the total mass is just the mass of the bucket (m_bucket = 2.50 kg). Using the period equation, we can calculate the shortest period:

T_shortest = 2π√(m_bucket / k) = 2π√(2.50 kg / 450 N/m) ≈ 0.491 s

The height of the parabolic arch bridge at distances of 10, 30, and 50 feet from the center is 19.7917, 23.9583, and 25.0000 feet, respectively.

To answer this question, we must first choose a suitable rectangular coordinate system. The origin, (0,0), of the coordinate system should be located at the center of the bridge, which is located at x = 0. The y-axis should be perpendicular to the bridge and the x-axis should be parallel to the bridge.

To find the height of the arch at distances of 10, 30, and 50 feet from the center, we can use the formula for a parabolic arch, y = a(x - h)² + k. We can calculate the coefficients a and k by using the given maximum height and span of the bridge. We can set y = 25 and x = 120, and then solve for a and k.

\(a = \dfrac{-25}{1202}\)

a = -0.04167,

k = 25

Now, we can substitute the distances of 10, 30, and 50 feet into the formula, and calculate the corresponding height values.

At x = 10 feet: y = -0.04167(10 - 0)2 + 25 = 19.7917 feet

At x = 30 feet: y = -0.04167(30 - 0)2 + 25 = 23.9583 feet

At x = 50 feet: y = -0.04167(50 - 0)2 + 25 = 25.0000 feet

Therefore, the height of the parabolic arch bridge at distances of 10, 30, and 50 feet from the center is 19.79, 23.95, and 25.00 feet, respectively.
