The instantaneous velocity of the object is 137.2 m/s along the downward direction.

Instantaneous velocity: The velocity of an object at a particular instant of time is called the instantaneous velocity.

Note: The y-axis is taken along the upward direction so acceleration due to gravity will be negative.

Any object that is falling freely is acted upon by gravity. The first equation of motion gives the relationship between initial velocity, the velocity at time t, time, and acceleration. The equation is,

v=u+at

where v is the velocity at time t, u is the initial velocity, t is the time, and g is the acceleration due to gravity. Since the object starts from rest, its initial velocity is zero.

For the given case, u=0, a=-9.8 m/s^2 and t=14 s. Put the values in the equation to get the instantaneous velocity of the object at t=14 s.

v=0+(-9.8)(14)

v=-137.2 m/s

Dilation of a figure with reflectional or rotational symmetry the  resulting image will have symmetry.

Dilation is the process of altering an object's or shape's size by reducing or enlarging its dimensions by a certain amount of scale. A circle with a radius of 10 units, for instance, is reduced to a circle with a radius of 5 units. This technique is applied in art and craft, photography, and logo design, among other fields. There are four fundamental types of transformations in geometry.

Resizing an item uses a transition called dilation. Dilation is used to enlarge or contract the items. The result of this transformation is a picture with the same shape as the original. However, there is a variation in the shape's size. The initial form should be stretched or contracted during a dilatation. The phrase "scale factor" describes this transition.

The scale factor is defined as the proportion of the new picture's size to that of the previous image. A fixed location in the plane serves as the centre of dilation. The scale factor and the centre of dilation are used to determine the dilation transformation.

The mass of kerosene needed to boil 5 liters of water at 10°C is approximately 28070 kg.

To determine how much kerosene is needed to boil 5 liters of water at 10°C, we must first determine how much heat is needed to bring the water's temperature up to 100°C and then boil it at that degree.

Heating water from 10°C to 100°C:

4.186 J/g°C (or 4.186 kJ/kg°C) is the specific heat capacity of water. As a result, J is the quantity of heat needed to raise the temperature of 5 liters (or 5000 grams) of water from 10°C to 100°C is:

Q1 = m x c x ΔT

= 5000 g x 4.186 J/g°C x (100°C - 10°C)

= 1952200 J

Water vaporizes at a heat of 2260 kJ/kg (or 2.26 × 106 J/kg) at 100 °C when it is heated to boiling. To boil 5 liters (or 5000 grams) of water at 100°C, the following amount of heat is needed:

Q2 = m x L

= 5000 g x 2.26 x 10^6 J/kg

= 1.13 x 10^10 J

To heat and boil the water, the following amount of heat is needed:

Qtot = Q1 + Q2

= 1952200 J + 1.13 x 10^10 J

= 1.149522 x 10^10 J

Where m is kerosene's mass, c is kerosene's specific heat capacity (4.6 kJ/kg°C), and ΔT is the temperature change of the kerosene.

Assuming that the initial temperature of the kerosene is also 10°C, the temperature change of the kerosene is:

ΔT = 100°C - 10°C

     = 90°C

Substituting the values into the equation, we get:

1.149522 x 10^10 J = m x 4.6 kJ/kg°C x 90°C

Solving for m, we get:

m = 28069.6 kg

Hence, 28070 kg of kerosene is required to boil 5 liters of water at 10°C.

Electric current rises when voltage rises because the two quantities in a conductor are directly related.

According to Ohm's law, the resistance (R) in a circuit has an inverse relationship to the electrical current (I), which is proportional to the voltage (V). Consequently, if the voltage is raised, the current will rise as long as the circuit's resistance remains constant.

For a simple understanding, assume, voltage, in essence, exerts "electric pressure" on the charges. The "pressure" that drives them increases with voltage, so it makes sense that their speed—what we refer to as current—increases as well.

How much current flows depends on the battery's voltage, or the difference in electric potential.

Yes, Admiralty Head does have mixed tides.

Mixed tides are characterized by two high tides and two low tides of different heights each day. This occurs in locations where the gravitational pull of the moon and sun have a stronger influence on the tides, such as at Admiralty Head.

In general, tides are caused by the gravitational pull of the moon and sun on the Earth's oceans. The moon has a stronger influence on tides due to its closer proximity to Earth. However, the sun's gravitational pull also plays a role in the formation of tides.

At Admiralty Head, the mixed tides occur because the moon's gravitational pull is stronger on one side of the Earth than the other, causing the two high tides and two low tides to be of different heights. This creates a unique tidal pattern that is characteristic of Admiralty Head.

In conclusion, Admiralty Head does have mixed tides due to the stronger influence of the moon and sun's gravitational pull on the tides in this location.

To drag the box from point A to B on a horizontal surface using a horizontal force of 10 N, a work of 60 joules (J) must be done over a distance of 6 meters (m).

On a horizontal surface, if a box is dragged from point A to B by a horizontal force of 10 N, the work done can be calculated using the formula:

Work = Force x Distance

In this case, the force applied is 10 N and the distance between points A and B is 6 m.

Plugging these values into the formula, we get:

Work = 10 N x 6 m = 60 Nm

The unit for work is joules (J), so the work done in this scenario is 60 J.

When a force is applied to move an object, work is done.

The work done is calculated by multiplying the force applied by the distance over which the force is exerted.

In this case, the force applied is 10 N and the distance is 6 m.

Multiplying these values gives us the work done, which is 60 J.

The magnitude of the electric field on the y-axis can be calculated using Coulomb's law formula. Coulomb's law states that the electric field strength (E) at a certain point is equal to the magnitude of the charge (q) divided by the square of the distance (r) between the charges, multiplied by a constant (k).

First, let's calculate the value of the constant (k). The value of k is 9 × 10^9 Nm^2/C^2.

Next, we can use the formula E = k * (q / r^2) to find the magnitude of the electric field.

Given that q1 = 75 nc and q2 = -8.0 nc, the net charge (q) would be the sum of the two charges: q = q1 + q2.

Now, let's calculate the distance (r) between the charges. In this case, the y-coordinate of the point is given as y = 3.0 m. Since we are calculating the magnitude of the electric field on the y-axis, the distance would be r = y.

Plugging in the values, we have:
q = 75 nc + (-8.0 nc) = 67 nc
r = y = 3.0 m

Using Coulomb's law formula, we get:
E = (9 × 10^9 Nm^2/C^2) * (67 nc / (3.0 m)^2)

Simplifying the calculation:
E = (9 × 10^9 Nm^2/C^2) * (67 × 10^-9 C) / (3.0 m)^2

E = (9 × 10^9 Nm^2/C^2) * (67 × 10^-9 C) / (9.0 m^2)

E = 603 N/C

Therefore, the magnitude of the electric field on the y-axis at y = 3.0 m is 603 N/C.

Note: The magnitude of the electric field is always positive, so the negative sign in q2 does not affect the magnitude.

The answer is C- the atoms have different. A. Topic numbers

Explanation:

if they have the same neutrons and protons but not electrons the atomic numbers cant be the same if they dont have all 3 of the same numbers.

(on edge 2020-2021)

The atoms have different atomic numbers.

The atomic number of an atom is equal to the number of protons in its nucleus. Since Atom A and Atom B have the same number of protons and neutrons, they have the same atomic mass, which is the sum of protons and neutrons in the nucleus.

However, the number of electrons in an atom can vary. An atom is electrically neutral, which means it has the same number of protons and electrons. If Atom A and Atom B have different numbers of electrons, they will have different charges. One atom may have gained or lost electrons, making it either negatively charged (anion) or positively charged (cation), while the other remains neutral.

The chemical symbol of an element represents the identity of the element, and it is determined by the number of protons in the nucleus, which is the atomic number. Since the atoms have different atomic numbers, they will have different chemical symbols.

Therefore, the correct statement is that the atoms have different atomic numbers, as their atomic numbers determine their chemical identity.
