Over the course of the 4 hours for which farmer Joe's tractor is pulling the heavy plow, the plow is gaining energy by virtue of its displacement --termed the Kinetic energy.

According to the question, Farmer Joe drives the tractor for 4 hours.

However, the tractor is connected to a heavy plow and is used to pull the plow across a rocky field.

The question requires that we determine if the plow is gaining or losing energy.

However, the focus of the question is during the pulling action of the tractor on the plow.

Ultimately, the plow is gaining energy as it is being pulled by the tractor and now has Kinetic energy.

Answer:

In June 1783, Lavoisier reacted oxygen with inflammable air, obtaining "water in a very pure state." He correctly concluded that water was not an element.

Explanation:

As the fire left behind ashes of a substance it indicated that it is not an element as element cannot be decomposed in to simpler substances.

It is defined as a substance which cannot be broken down further into any other substance. Each element is made up of its own type of atom. Due to this reason all elements are different from one another.

Elements can be classified as metals and non-metals. Metals are shiny and conduct electricity and are all solids at room temperature except mercury. Non-metals do not conduct electricity and are mostly gases at room temperature except carbon and sulfur.

The number of protons in the nucleus is the defining property of an element and is related to the atomic number.All atoms with same atomic number are atoms of same element.

Yes, she can slowly improve her capacity and move to aerobic exercise later. The correct option is (D).

Even if it isn't initially aerobic, starting with walking is a wonderful place to start, especially if Bettina isn't used to exercising frequently. Walking is a low-impact activity that is simple to fit into daily life and can be used as a gentle introduction to developing a habit of physical activity.

Even while walking isn't typically thought of as an aerobic workout, it nevertheless has several health advantages, including enhancing cardiovascular health, boosting energy, lowering stress, and aiding in weight management. Bettina can eventually increase the length and intensity of her walks to make them aerobic as she steadily increases her endurance and fitness level through walking.

Answer:

Explanation: Just multiply  V/D=Mass

Answer:

12,433 km

Explanation:

I got this by doing 33,155 and dividing it by 60, which is km per minute, then I did 552.583333, which is km per minute and multiplied it by 22.5, which equals 12,433 km

To check this you can do 12,433 times 2, which is 45 minutes and then use 552.583333, which is per minute, and multiplying by 15, which is 15 minutes, then add

(12,433 x 2 = 24,866) add 8288.75 [15 minutes] and that gets you 33,155

When one force is greater than another force, we can say that there is a change in motion. The correct answer is option C: "There is a change in motion."

According to Newton's second law of motion, the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. When one force is greater than another force, the net force acting on the object is not zero. If the net force acting on an object is not zero, it will cause the object to accelerate in the direction of the larger force. This acceleration leads to a change in motion. The object may speed up, slow down, change direction, or a combination of these.

Option A, "There is no net force," is incorrect because if one force is greater than another, there is a net force acting on the object.

Option B, "There is no change in motion," is incorrect because, as explained above, a greater force leads to a change in motion.

Option D, "The forces are in equilibrium," is incorrect because if one force is greater than another, the forces are not balanced, and the object is not in equilibrium.

Therefore, the correct statement is that there is a change in motion when one force is greater than another force.

Answer: It's Friday night and Skyler has been assigned the noble task of baby-sitting Casey, his 2-year old brother. He puts a crash helmet on Casey, places him in the red wagon and takes him on a stroll through the neighborhood. As Skyler starts across the street, he exerts a 52 N forward force on the wagon. There is a 24 N resistance force and the wagon and Casey have a combined weight of 304 N. Construct a free body diagram depicting the types of forces acting upon the wagon. Then determine the net force, mass and acceleration of the wagon.

Explanation:

When Skyler exerts a force of 52 N on the wagon and there is a 24 N resistance force and the wagon and Casey have a combined weight of 304 N then Net force, mass and acceleration of the wagon will be 305.2 N, 31.02kg and 0.9 m/s² resp.

Force is responsible for the motion of an object. it produces acceleration in the body. According to newton's second law force is mass times acceleration i.e. F =ma. Its SI unit is N which is equivalent to kg.m/s². There are two types of forces, balanced force and unbalanced force. when net force acting on body is zero then it is called as balanced force and net force on the body is non zero then it is called as unbalanced force. unbalanced force are responsible for the motion of the body.

in this problem, Skyler is applying 52 N force to a wagon, there is resistance of 24N of force. Combined Wight is 304 N is directed downwards. a vector diagram is shown in the figure which gives the Net force.

the resultant force between resistance and applied force

F = 52 - 24 = 28N... means total of 28N of actual force is applied on the wagon in x direction.

There is downward force as weight, hence magnitude of net force acting on the wagon is.

F²(net) = F₁²+F₂² + F₁F₂cosθ

θ = 90, cos 90 = 0

F²(net) = F₁²+F₂²

F²(net) = 28² + 304²

F²(net)  = 93200

F (Net) = [tex]\sqrt{93200\\[/tex] = 305.2 N

To get mass and acceleration,

weight W = mg

304 = m*9.8

m = 31.02 kg mass of the wagon is 31.02kg

F = ma

28 = 31.02*a

a = 0.9 m/s²

Acceleration of the wagon is 0.9 m/s². this is forward acceleration.

Hence Net force, mass and acceleration of the wagon is 305.2 N, 31.02kg and 0.9 m/s² resp.

How much negative charge has been removed from a positively charged electroscope if it has a charge of 7.5x10-11C?

If C is Coulombs then, −1 C is equivalent to the charge of approximately 6.242×10^18 electrons.

You already gave the answer: -7.5x10–11C

It is like asking: What colour is my white horse?

Now if you want to know how many electrons have been removed, then multiplying the number of electrons in a coulomb by the coulombs you have, you get 4.6815 x 10^8 electrons. Which is almost the same answer as before.

3.7 x 10^8 electrons are removed from a positively charged electroscope.

The magnitude of charge carried by one electron is 1.602 x 10^-19 C

From the question, we can see that the net charge on the electroscope is 6 x 10^-11 C

Given that;

6 x 10^-11 = 1.602 x 10^-19 n

Where n is the number of electrons removed from a positively charged electroscope

Therefore;

n = 6 x 10^-11/ 1.602 x 10^-19

n = 3.7 x 10^8 electrons

Answer:

22.9km

Explanation:

If the mountain is 1.00 km higher in elevation than your position and the angle measured from your position to the top of a mountain is 2.50∘.then you would have been 22.9 km far away from the mountain

A right-angled triangle's side ratios are the easiest way to express a function of an arc or angle, such as the sine, cosine, tangent, cotangent, secant, or cosecant. These functions are known as trigonometric functions.

As given in the problem you measure the angle from your position to the top of a mountain to be 2.50∘. If the mountain is 1.00 km higher in elevation than your position,

By using the tangent trigonometric function for the right triangle

tanθ = height /distance

tan 2.5° = 1000 m /distance

distance =1000 m /tan 2.5°

              =22903 m

              =22.9 km

Thus, the mountain is 22.9 km far away from your position
