F = ma, or force is equal to mass times acceleration, is the equation used in Newton's second law of motion to demonstrate the relationship between force and acceleration.
What is force and acceleration?A force pushes or pulls an object. The total of all forces acting on an object is known as the net force. An object will change speed in the direction of the net force when there is one applied to it. The object's acceleration reveals how much it accelerates or decelerates.
Newton's second law of motion explains the connection between force and acceleration. They are of the same size. The acceleration of an object rises by the same amount as the force being applied to it. Force is simply defined as mass times acceleration.
What is the acceleration force formula and Can you have acceleration without a force?Mass (kg) times acceleration (m/s2) equals force (N). Therefore, an object with constant mass will accelerate in direct proportion to the applied force.
There won't be any acceleration if there are no external forces operating on the object. The object will move at a constant speed if there is no acceleration. We may examine Newton's second law and the acceleration formula mathematically.

inventory holding costs,Regular production costOvertime costBackorder/lost sales cost.What is aggregate planning?Aggregate planning is a method for creating a comprehensive manufacturing plan that ensures continuous production at a facility. Aggregate production planning is typically applied over a three to eighteen-month period. It is the activity of matching output supply with demand over a medium time span using information derived from inventory levels.
This ultimately implies that aggregate planning is a strategic technique used by organizations to make an aggregate plan for their manufacturing (production) process ahead of time, in order to have an idea of the level of goods to be produced and what resources are required so that the total cost of production is kept to a bare minimum.
Production and inventory costs are the two major cost categories required as inputs for aggregate planning. Production costs include regular and overtime labor costs, costs of subcontracting production, costs of changing capacity by hiring or laying off workers, and costs of increasing or decreasing machine capacity.

What is Another Earth Just 12 Light-Years Away?Three times closer to Earth than Alpha Centauri, the nearest star to our sun, Tau Ceti is only 12 light-years away. Tau Ceti is so similar to the sun that it was chosen as the first target by astronomer Frank Drake in 1960. Drake has long searched for radio signals from potential extraterrestrial civilizations. Only one in every twenty-five stars is like the sun in brightness, temperature, and size, yet Tau Ceti is a brilliant G-type yellow main-sequence star. Tau Ceti is also a single star system, meaning there isn't another star in the system whose gravity may tug planets away like Alpha Centauri, which also contains a G-type star and even a planet.The University of Hertfordshire in the United Kingdom and its astronomer Mikko Tuomi examined more than 6000 observations of Tau Ceti made with telescopes in Chile, Australia, and Hawaii.

What is Speed ?Speed is a distance travel per time taken. It is a scalar quantity and it is measured in m/s
Given that a person standing at the edge of a seaside cliff kicks a rock horizontally of the cliff from a height of 52 m and it lands a distance of 35 m from the base of the cliff.
The rock will move vertically downward with initial velocity = 0. The time taken will be constant. That is, same horizontally.
Let us first calculate the time by using the formula
h = ut + 1/2gt²
Where
h = 52 mu = 0Range R = 35 mg = 9.8 m/s²Substitute all the necessary parameters into the formula
52 = 0 + 1/2 × 9.8 × t²
52 = 4.9t²
t² = 52/4.9
t² = 10.6
t = √10.6
t = 3.26 s
The speed at which the rock was initially kicked can be found by

A. 10 kg
B. 15 kg
C. 20 kg
D. 25 kg
The mass of the object experimented on in this situations is 20 kg. So, option(C) is correct.
What is force?
A force is something that pushes or pulls an object. The objects' interactions with one another are what causes push and pull. Force can also be expressed using words like stretch and squeeze.
When an object with mass is pushed or pulled, it changes its velocity, according to the definition of force in physics.
The product of mass (m) and acceleration (a) represents the amount of force (F). Mathematically speaking, the force equation or formula can be written as follows:
F = ma
According to given parameters:
Force = 30 N; acceleration = 1.5 m/s². So, mass = 30/1.5 kg = 20 kg.
Force = 70 N; acceleration = 3.5 m/s². So, mass = 70/3.5 kg = 20 kg.
Force = 85 N; acceleration = 4.25 m/s². So, mass = 85/4.25 kg = 20 kg.

5.01×10¹³w/m² is the intensity of a sound wave with a relative intensity of 13.7 dB(option -b).
How does wave relative intensity work?The less formal term for relative intensity level is the "decibel level" of a sound. It differs from intensity in that relative intensity level uses a logarithmic scale to more closely mimic how people experience loudness.
Given,
The sound wave with relative intensity = 13.7dB.
We will apply the formula provided by to determine the sound wave's intensity.
B = log₁₀I/I₀
When we solve for I/I₀ and plug the value of B into the above relation, we get:
13.7dB = 10×log₁₀I/I₀
solving,
I/I₀ = [tex]10^{13.7}[/tex]
I/I₀ = 5.01×10¹³w/m².

What is the equation of motion?The equations of motion are used to establish the relationship between the acceleration, velocity, time, and displacement of a moving object.
The equations of motion are represented in the form of mathematical expressions as follows:
[tex]v = u + at\\S = ut +\frac{1}{2} at^2\\v^2-u^2= 2aS[/tex]
Given, the height of the table, h = 0.75 m
The horizontal speed of the ball, v = 0.8 m/s
The initial speed of the ball, u = 0
From the third equation of motion, calculate the time:
[tex]S = ut +(1/2)at^2[/tex]
[tex]0.75 = \frac{1}{2} (9.8) t^2[/tex]
t = 0.39 sec
The horizontal distance can be calculated from the formula of the velocity:
Horizontal distance = v × t = 0.8 × 0.39 = 0.312 m

What is the momentum of a 6.0 kg ball bowling with 9 velocity of 2.0 Metre per second?
the momentum of the 6 kg ball moving with haste of 2m/ s is 12 kgm/s.
In the question, we're given,
Mass = 6 kg
haste = 2 m/ s
According to the Newton's alternate law of stir it states that the instigation is the product of mass and the haste of the flyspeck. This instigation can be said as the measure of stir of the object. It's a vector volume and it has both magnitude and direction. It can be transferred. As the instigation of the system is conserved when no external force is applied on the system.
In this case,
momentum( p) = mv
Then,
m = mass
v = haste
momentum = 6 * 2
momentum = 12 kgm/ s
Thus, the momentum of the 6 kg ball moving with velocity of 2m/ s is 12 kgm/s.
