When a government pays ranchers to reduce the number of milk cows they have, it is known as a what ?
O Subsidy
O Tax Break
O Productivity Schedule
O Resource Cost
I say a subsidy because the government is controlling how many cows they have.
Answer:
Subsidy
Explanation:
When a government pays ranchers to reduce the number of milk cows they have, it is known as a subsidy.
Subsidy is an incentive given by a government in form of cash or raw materials in order to achieve a common goal.
It might be to increase production of certain commodities or phase out a particular product in the market.
The subsidy helps in paying part of the production costs

infrared light<<<----- CORRECT
visible light
Explanation:
Edge 2021
Infrared light is typically used to make images based on the temperatures of objects.
What is meant by electromagnetic spectrum?The range of all EM radiation arranged from high to low frequency (short to long wavelength) according to their frequency or wavelength. is known as the electromagnetic spectrum (EM).
Here,
Similar to visible light, X-rays are a type of electromagnetic radiation. X-rays have a higher energy than light, on the other hand, and can penetrate most materials, including the human body.
Images of inside body tissues and structures are produced using medical x-rays.
Electromagnetic energy in the infrared region of the spectrum can be seen by them. There is a relationship between an object's temperature and the electromagnetic radiation it releases since infrared radiation is strongly related to object temperature.
Hence,
Infrared light is typically used to make images based on the temperatures of objects.

The specific heat capacity of iron is 450.5. A 15.5 kg block of iron with
an initial temperature of 20 degrees Celsius is heated with 250 J. What will
the final temperature of the iron be?
Answer:
[tex]T_f=20.03^{\circ} C[/tex]
Explanation:
Given that,
The specific heat capacity of iron is 450.5 J/g°C
The mass of block of iron, m = 15.5 kg
Initial temperature, [tex]T_i=20^{\circ} C[/tex]
Heat required, Q = 250 J
We need to find the final temperature of the iron. The formula for heat required is given by :
[tex]Q=mc\Delta T\\\\Q=mc(T_f-T_i)\\\\\dfrac{Q}{mc}=(T_f-T_i)\\\\T_f=\dfrac{Q}{mc}+T_i\\\\T_f=\dfrac{250}{15.5(450.5)}+20\\\\T_f=20.03^{\circ} C[/tex]
So, the final temperature of the iron is [tex]20.03^{\circ} C[/tex].
A stationary 10 kg object is located on a table near the surface of the earth. The coefficient of kinetic friction between the surfaces is 0.2. A horizontal force of 40 N is applied to the object.
Answer:
2.04m/s²
Explanation:
Complete Question
A stationary 10 kg object is located on a table near the surface of the earth. The coefficient of kinetic friction between the surfaces is 0.2. A horizontal force of 40 N is applied to the object. Find the acceleration of the object.
According to Newtons second law;
\sum F_x = ma_x
F_m - F_f = ma_x
Fm is the applied force
Ff is the frictional force
m is the mass
a is the acceleration
Substitute the given values
40N - nmg = 10a
40 - 0.2(10)(9.8) = 10a
40 - 19.6 = 10a
20.4 = 10a
a = 20.4/10
a = 2.04m/s²
Hence the acceleration of the object is 2.04m/s²
Pls place the words in the right place I'll give brainless and the points!
Explanation:
you measure temperature in degrees celsius using a thermometer. Thermal energy is measured in joules. A larger volume of water will take longer to heat up but will store more energy than the smaller object. However, a smaller object will lose it's heat faster than a larger object. A cup of tea has less thermal energy than a swimming pool.
A ball rolls with a speed of 3 m/s across a level table that is 1.5m above the floor. How far along the floor is the landing spot from the table?
Answer:
d = 1.65 m
Explanation:
Given that,
The speed of a ball, v = 3 m/s
A ball rolls a level table that is 1.5 m above the floor.
We can find how long the ball is in free fall. We can use the second equation of kinematics as follows :
[tex]s=ut+\dfrac{1}{2}gt^2[/tex]
u is the initial speed in the vertical direction
So,
[tex]s=\dfrac{1}{2}gt^2\\\\t=\sqrt{\dfrac{2s}{g}} \\\\t=\sqrt{\dfrac{2\times 1.5}{9.8}} \\\\t=0.55\ s[/tex]
Now, using the formula of velocity.
[tex]v=\dfrac{d}{t}\\\\d=vt\\\\d=3\times 0.55\\\\d=1.65\ m[/tex]
So, the landing spot is at 1.65 m from the table.
of the following states of motion, the one which requires balanced forces is:
A: a decrease in speed in a straight line
B: an increase in speed in a straight line
C: constant speed in a straight line
D: a change in the direction of the motion
A balanced force is required for a change in the direction of the motion.
What is a force?According to Newton's second law of motion, the force applied to a body is directly proportional to the product of mass and acceleration of the body.
Balanced forces
Balanced forces are those that are opposite in direction and equal in size. When forces are balanced there is no change in direction.
Thus, when there is change in direction, a balance force can be applied to cancel the change in direction of motion.

What is the definition of endothermic and exothermic?
pls help on a timer will give brainlist
Answer:
An exothermic process releases heat, causing the temperature of the immediate surroundings to rise. While an endothermic process absorbs heat and cools the surroundings
Explanation:
Answer:
Basically, endothermic feels cooler to touch than exothermic.
Explanation:
Endothermic reactions are just reactions that emit energy (in form of heat) to its surroundings. Exothermic ones, on the other hand, draw energy from its surroundings to occur.
Always think - "Endothermic is cool. Exothermic is not cool."
A(n) ________________________ is a molecule that is soluble in both polar and nonpolar solvents.
Answer: ethanol which will dissolve in both water (a polar solvent) and gasoline (a non-polar solvent)
Explanation:
According to the concept of solubility, ethanol is a molecule which is soluble in both polar and non-polar solvents.
What is solubility?
Solubility is defined as the ability of a substance which is basically solute to form a solution with another substance. There is an extent to which a substance is soluble in a particular solvent. This is generally measured as the concentration of a solute present in a saturated solution.
The solubility mainly depends on the composition of solute and solvent ,its pH and presence of other dissolved substance. It is also dependent on temperature and pressure which is maintained.Concept of solubility is not valid for chemical reactions which are irreversible. The dependency of solubility on various factors is due to interactions between the particles, molecule or ions.

Explanation:
A spring has a constant of 875 N/m. and the mass which will cause this spring to stretch 4.5 meters is 401.78 kg.
What is Spring constant?The spring constant is a characteristic of a spring which is defined as the ratio of the force affecting the spring to the displacement which is caused by that force. The SI unit of spring constant is N.m⁻¹ (Newton per meter).
The spring constant is:
F = -k/ x
where, k is the spring constant
F denotes the force,
and x denotes the change in the length of the spring.
k = 875N/m
x = 4.5m
We know that
Kx = mg
m= kx/ g
m = 875 × 4.5/ 9.8
m = 401.78kg
Therefore, the mass which will cause this spring to stretch 4.5 meters is 401.78 kg.

Tafu is working with subatomic particles in the physics lab. a positron is traveling in a straight line down the particle accelerator. tafu models its position with the function p(t)= t2 t â 1 where t>1. in the limit calculations below, if you need to use -â or â, enter -infinity or infinity. (a) calculate the limit
Answer:
Infinity
Explanation:
When you have a limit approaching infinity one method you can use is to remember that the highest power dominants all of the other ones so when we have (t^2)/t-1 like in your problem, we see that t^2 has the highest power of 2 so if that's going to infinity and it's not being divided by any powers higher than it will just be inifinity.
We have that for the Question, it can be said that in the limit calculations below, if you need to use -â or â, enter -infinity or infinity. the limit is
[tex]Lim_{t->\infty} p(t)= \infty[/tex]
From the question we are told
Tafu is working with subatomic particles in the physics lab. a positron is traveling in a straight line down the particle accelerator.tafu models its position with the function

in the limit calculations below, if you need to use -â or â, enter -infinity or infinity.
(a) calculate the limit
Generally the equation for the Question is mathematically given as
[tex]p(t)=\frac{t^2}{t-1}\\\\Therefore\\\\For Lim_{\infty}\\\\We have\\\\ Lim_{t->\infty} p(t)= Lim_{t->\infty}\frac{t^2}{t-1}\\\\[/tex]
