The incentive theory says people are "pulled" by external stimuli to act a certain way.
Humans have both main and secondary needs that must be met in order for them to feel needed. These requirements naturally nudge a person in that direction. Hunger, thirst, and a desire for sexual activity are examples of fundamental wants. Secondary needs, on the other hand, are those that depend on advantages, with financial requirements serving as the finest illustration.
According to incentive theories, conduct is driven by the "pull" of external objectives like rewards, money, or recognition. It's simple to imagine a variety of circumstances in which a specific objective, like a job promotion, can act as an outside incentive to encourage certain actions.

How do you calculate potential due to charge?By multiplying K, the electric constant, by one charge, then by the other charge, and finally by the distance between the two charges, we may determine the electrical potential energy between two charges.A point charge's electric potential is V=kQ/r, or V = k Q / r. Electric field is a vector while electric potential is a scalar. The voltage resulting from a combination of point charges can be calculated by adding voltages as integers, whereas the overall electric field can be calculated by adding individual fields as vectors.V = k × [q/r]
V = electric potential energy.
q = point charge.
r = distance between any point around the charge to the point charge.

The parametric equations of the velocity as a function of time are Vx (t) = 2.4 and Vy (t) = - 2.4 · t, respectively.
How to find the parametric equations of the velocity
Parametric equations are equations in terms of a single variable t, the velocity of the particle is the first derivative of position, whose definition is shown below:

Like in case of other cluster decays, Alpha decay is also a fundamentally quantum tunnelling process.
Understanding Q Value in Alpha Decay:
In Physics, the Q-value is defined as the difference between the sum of the rest masses of original reactants and the sum of final product of masses. In simpler terms, we can say that the Q-value is the difference between the final and initial mass energy of the decayed products.

There is more energy with the light of wavelength 580 nm compared to 660nm as energy is inversely related to wavelength.
The energy of a radiation type is inversely proportional to its wavelength. This means energy increases with decreases in wavelength, and energy decreases with increases in wavelength. The relation between energy, wavelength, and frequency is shown by the equation E = hν = hc/λ.

In a certain area of space, electric field lines provide details on the direction (and intensity) of an electric field. At a particular position, a field line is drawn perpendicular to the net. Therefore, the tangent to the electric field line at any place coincides with the direction of the electric field there.
To ascertain the electric field of a point charge, apply Coulomb's law. From the point charge, the electric field radiates in all directions. Always pointing away from positive charges and toward negative charges are electric field lines. In actuality, positive charges initiate electric fields, which terminate at negative charges. Field lines never cross each other, as well. If they do, it indicates that there are two directions to the electric field there.

You are standing over a 30 m cliff with a water fall. What is the potential energy of 300 kg of water as it starts the decent from the top of the waterfall? Remember, where g = 9.81 m/s2
Answer:
Therefore, the potential energy of 300 kg of water as it starts the descent from the top of the 30 m waterfall is 294.3 Joules.
Explanation:
In this case, you are given that the mass of the water is 300 kg, and the height of the waterfall is 30 m. The acceleration due to gravity is given as 9.81 m/s2. Plugging these values into the formula, you can find the potential energy of the water as it starts the descent from the top of the waterfall:
PE = 300 kg * 9.81 m/s2 * 30 m
= 294.3 kg * m^2/s^2
= 294.3 Joules
The potential energy of 300 kg of water as it starts the descent from the top of the 30 m waterfall is 294.3 Joules.
What is potential energy?Potential energy is a form of stored energy that is dependent on the relationship between different system components. When a spring is compressed or stretched, its potential energy increases. If a steel ball is raised above the ground as opposed to falling to the ground, it has more potential energy.
Given parameters:
Mass of the water: m = 300 kg.
Acceleration due to gravity: g = 9.81 m/s²
Height: h = 30 m.
Hence, potential energy of the water at the top of the waterfall =
mass × acceleration due to gravity × height
= 300 kg × 9.81 m/s² ×30 m
= 294.3 kg-m²/s²

The force on the vehicle is 500000 N means that a force of 500000 N is being applied to the vehicle and its momentum is changing at a rate of 500k kg m/s²
Well, we all know Force is equal to the product of mass and acceleration. Force is nothing but, a measure of the rate of change of momentum of an object. When we say the force acting on any particle is x newtons, we mean that the particle is accelerating at x/m meter per square second at that instant (where m is the mass of the particle). In this case, we have been given that the force applied on the vehicle is 500000 newtons. 500000 newtons can be also written as 500k Newtons. So when we are applying a force of 500k Newtons on the vehicle, in this case, we can't really find the acceleration of the vehicle as no mass is given. But we can tell one thing here, that is, a force of 500k Newtons on the vehicle means that at that particular instant the rate of change of momentum is

A tariff is a type of tax that a country imposes on imported goods at its borders. Tariffs have historically been a tool for governments to generate revenue, but they are also a way governments seek to protect domestic producers.
As a protectionist measure, tariffs increase the price of imported goods. As a result, consumers choose to buy relatively cheap domestic products instead.

How do I determine the current?We know that charge, current and time are related by the following formula:
Charge (Q) = Electric current (I) × time (t)
Q = It
Divide by t
I = Q / t
With the above formula, we can obtain the current. Details below:
A. How do I determine the current?
Charge (Q) = 4.5 CTime (t) = 1 sCurrent (I) = ?I = Q / t
I = 4.5 / 1
I = 4.5 A
B. How do I determine the current?
Charge (Q) = 192 CTime (t) = 1 min = 60 sCurrent (I) = ?I = Q / t
I = 192 / 60
I = 3.2 A
C. How do I determine the current?
Charge (Q) = 16.56 KC = 16.56 × 1000 = 16560 CTime (t) = 1 h = 1 × 60 × 60 = 3600 sCurrent (I) = ?I = Q / t
I = 16560 / 3600
I = 4.6 A
D. How do I determine the current?
Charge (Q) = 1.8 CTime (t) = 0.6 sCurrent (I) = ?I = Q / t
I = 1.8 / 0.6
I = 3 A
E. How do I determine the current?
Charge (Q) = 3.2 CTime (t) = 1.6 sCurrent (I) = ?I = Q / t
I = 3.2 / 1.6
I = 2 A
F. How do I determine the current?
Charge (Q) = 33.8 CTime (t) = 2.6 sCurrent (I) = ?I = Q / t
I = 33.8 / 2.6
I = 13 A
G. How do I determine the current?
Charge (Q) = 147.2 CTime (t) = 2.6 sCurrent (I) = ?I = Q / t
I = 147.2 / 23
I = 6.4 A
H. How do I determine the current?
Charge (Q) = 7920 CTime (t) = 15 mins = 15 × 60 = 900 sCurrent (I) = ?I = Q / t
I = 7920 / 900
I = 8.8 A
I. How do I determine the current?
Charge (Q) = 7920 C
Time (t) = half hour = 30 mins = 30 × 60 = 1800 s
Current (I) = ?
I = Q / t
I = 900 / 1800
I = 0.5 A

1. What is the formula for Acceleration?
Answer:
The formula of acceleration (a) = velocity (v)- initial velocity (u) /time taken(t)
A car starts at rest and travels 100 m in 5 seconds. What is the car's acceleration?
Answer:
[tex]4 m/s^{2}[/tex]
Explanation:
You can use the formula a = (v2 - v1)/t, where a is the acceleration, v1 is the initial velocity, v2 is the final velocity, and t is the time interval.
In this case, v1 is 0 m/s (since the car starts at rest) and v2 is the final velocity of the car after it travels 100 m in 5 seconds. You can use the formula v = d/t to find the final velocity, where v is the velocity, d is the distance traveled, and t is the time taken. Plugging in the given values, you get:
v = d/t
= 100 m / 5 s
= 20 m/s
Now you can plug in the values for a, v1, v2, and t into the formula to find the acceleration:
a = (v2 - v1)/t
= (20 m/s - 0 m/s)/5 s
= [tex]4 m/s^{2}[/tex]
