The time that is taken by the cart is given as 34.7 s.

What is the time taken?

Let us have it at the back of our minds that what we are dealing with here is the velocity and that the velocity of the object can be said to be a vector quantity. If it is a vector quantity, we would need to look at the magnitude and the direction of the quantity.

We can now see that the velocity of the object can be defined as the change in the velocity of the object with time. We can now write;

V = Δx/t

V = velocity

Δx = change in the displacement

t = time

Then;

-0.418 = 5.40 - 19.9/t

t = -14.5/-0.418

t = 34.7 s

In the movement of the cart from one point on the plane to the other, the time that has been taken by the cart is about 34.7 s.

A(n) __________ is the attribute in the supertype entity that determines to which entity subtype each supertype occurrence is related.
a. subtype discriminator
b. inheritance discriminator
c. specialization hierarchy
d. entity supertype

Answers

A subtype discriminator is the attribute in the supertype entity that determines to which entity subtype each supertype occurrence is related. Option (a) is correct.

The entity supertype is a concept in a database schema that represents a group of entities that share the same attributes or characteristics. A subtype is a subset of entities that possess specific distinguishing characteristics or attributes that are not present in the supertype. A subtype will have at least one different attribute or relationship, apart from all of the characteristics that the supertype contains.

A subtype is a refinement of a supertype entity. An entity type, known as the supertype, has multiple subtypes that can be derived from it. Subtypes may be exclusive (disjoint) or nonexclusive (overlapping). Exclusive subtypes contain nonoverlapping entities, whereas nonexclusive subtypes have overlapping entities.

Supertype and subtype entities can be used in conjunction with the entity-relationship model. A subtype is a distinct entity that has one or more attributes that are specific to it but not present in its supertype. The subtype of an entity is said to be derived from its supertype by extension or specialization.

Therefore, option (a) is correct.

What is the partial pressure and percentage of sea-level oxygen at the top of lab?

Answers

The partial pressure and percentage of sea-level oxygen at the top of a lab can be calculated using the concept of Dalton's Law of Partial Pressures. First, let's understand what partial pressure means. In a mixture of gases, each gas exerts a pressure that is proportional to its concentration.

The partial pressure of a gas is the pressure it would exert if it occupied the entire volume alone. To calculate the partial pressure of oxygen at the top of a lab, we need to know the percentage of oxygen in the air at sea level. The percentage of oxygen at sea level is approximately 21%. Now, to calculate the partial pressure at the top of the lab, we need to know the total atmospheric pressure at that height.  


Partial Pressure of Oxygen = Percentage of Oxygen * Total Atmospheric Pressur The  partial pressure of oxygen at the top of the lab would be 0.21 * P. Please note that the exact value of the total atmospheric pressure at the top of the lab is needed to provide a specific answer. Additionally, this is a simplified explanation of the concept, and there may be other factors to consider in a more detailed analysis.

a 10m long pendulum is displaced 37 degrees from equilibrium if it is released how fast will it be moving as it passes the lowest point

Answers

When a 10 m long pendulum is displaced 37 degrees from equilibrium and is released, the speed at which it will be moving as it passes the lowest point is 13.11 m/s.

The formula for the velocity of a simple pendulum is as follows:

v = (gl)^(1/2) × [1 - cos(θ)]

where

v is velocity

g is gravitational acceleration

l is length of the pendulum

θ is the displacement angle (in radians)

Given that the pendulum is 10 m long and displaced 37 degrees from equilibrium, we need to convert the displacement angle to radians:

θ = 37 degrees = 37 × (π/180) radians = 0.647 radians

Substituting the given values into the formula:

v = (gl)^(1/2) × [1 - cos(θ)]v = (9.81 × 10)^(1/2) × [1 - cos(0.647)]v = 13.11 m/s

Therefore, the speed at which the pendulum will be moving as it passes the lowest point is 13.11 m/s.

a rock is thrown upward with a velocity of 12 meters per second from the top of a 42 meter high cliff, and it misses the cliff on the way back down. when will the rock be 12 meters from ground level?

Answers

The rock will be 12 meters from the ground level after it has been thrown upward with a velocity of 12 meters per second from the top of the 42 meter high cliff for a total of 3.5 seconds.

What is the cliff?

The cliff is the height that generally has the highest height and it can be mountains, stones, buildings.

This is because the total time taken for the rock to fall back down will be the same as the total time taken for the rock to reach the top of the cliff. The equation used to calculate this is: time = distance / velocity. Therefore:

Time = 42 meters (cliff height) / 12 meters per second (velocity) = 3.5 seconds.

So, the rock will be 12 meters from the ground level after 3.5 seconds.

A 0.050 kg ball starts from rest at some unknown height on a toy roller coaster.
At a later time, it travels through the top of a loop at 2 m/s and a height of 0.40 m.
Since this track is frictionless, what was the starting height of the ball?

Answers

Answer:

The starting height of the ball is approximately 0.604 m

Explanation:

The given parameters are;

The mass of the the ball = 0.050

The speed with which it travels through the top loop = 2 m/s

The given height at which the ball moves at 2 m/s = 0.40 m

Therefore, we have;

1/2·m·v² = m·g·h

1/2·v² = g·h

h = 1/2·v²/g = 1/2 × 2²/9.81 ≈ 0.204

The additional height = h = 0.204 m

Therefore;

The starting height of the ball  ≈ The given height at which the ball moves at 2 m/s + h

The starting height of the ball  ≈ 0.40 + 0.204 = 0.604 m

The starting height of the ball ≈ 0.604 m.

When any object in rest, then potential energy is present. But when object is in motion then object have kinetic energy.

Starting height of the ball is 0.604 m.

We know that, when any object is start from rest, then potential energy is converted into kinetic energy.

     \(\frac{1}{2}mv^{2} =mgh\)

Where m is mass of object, g is gravitational acceleration , h is height and v is velocity of object. (value of g = 9.81 m/ second square)

from above equation,

we get,     extra height        \(h=\frac{v^{2} }{2g} \\\\h=\frac{4}{2*9.81}\\\\h=0.204\) meter

The starting height of the ball will be sum of the height at which ball moves 2 m/s and extra height.

Starting height = 0.40 + 0.204 = 0.604 meter.

The end velocity of an object is equal to its initial velocity plus its acceleration multiplied by the period of travel, according to the formula used in this velocity calculator.

What is Final velocity?

As long as three of the variables are known, this calculator can be used to determine initial velocity, ultimate velocity, acceleration, or time.

Initial velocity (u) squared plus two times the acceleration (a) times the displacement equals final velocity (v) squared.

When the body has achieved the maximum acceleration over a period of time, final velocity enters the picture. The acceleration is the difference between the object's initial and final velocities over time.

what is the last thing you should do just before moving away from the right curb to enter traffic?

Answers

Before moving away from the right curb to enter traffic, it is essential to perform several important checks to ensure a safe maneuver.

First, ensure that your vehicle is properly positioned close to the right curb, allowing enough space for traffic to pass on your left. Adjust your side and rearview mirrors to provide maximum visibility.

Once your vehicle is properly positioned, activate your turn signal to indicate your intention to merge into traffic. Check your rearview mirror to assess the speed and distance of approaching vehicles. Then, glance over your left shoulder to check your blind spot, an area that may not be visible in your mirrors.

This last shoulder check is critical as it helps you identify any vehicles, cyclists, or pedestrians that may be approaching from behind and could potentially be in your path as you move away from the curb. By performing this check, you can ensure that there are no hidden hazards and that it is safe to merge into the traffic lane.

Remember, maintaining awareness of your surroundings and performing the necessary checks before entering traffic is vital for a safe and successful merge.

To reduce heat loss through windows, it is customary to use a double pane construction in which adjoining panes are separated by an air space. If the space is 10 mm. And the glass surface in contact with the air have temperatures of 10C and -15C, what is the rate of heat loss from a 1mx2m window

Answers

To reduce heat loss through windows, it is customary to use a double pane construction in which adjoining panes are separated by an air space. If the space is 10 mm and the glass surface in contact with the air have temperatures of 10°C and -15°C, the rate of heat loss from a 1m x 2m window is: 2.78 x 10^3 J/h (Joules per hour).

Temperature of glass surface at side 1 (T1) = 10 °C.

Temperature of glass surface at side 2 (T2) = -15 °C.

The thickness of air space (d) = 10 mm.

The area of the window = 1 m × 2 m = 2 m².

Q/t = K × A × ΔT/dQ/t = (K × A × ΔT)/d.

Q/t = Heat loss rate, t = time, K = Thermal conductivity of air, A = Area of the window, ΔT = Temperature difference between the two surfaces, d = Thickness of air space.

ΔT = T1 - T2 = (10 °C) - (-15 °C) = 25 °CA = 2 m²d = 10 mm = 10 × 10^-3 m = 0.01 mK = 0.024 W/m·K

Q/t = [(0.024 W/m·K) × (2 m²) × (25 °C)]/0.01 mQ/t = 1200 W = 1200 J/s = 2.78 × 10³ J/h.
