Explanation: I plugged it on the formula

Coyote should drop the anvil when the Roadrunner is 20.3 meters away from the cliff.

The velocity of the object is defined as the fraction of the displacement of the object over a period of time.

We can solve this problem by finding the time it takes for the anvil to fall from the cliff to the ground, and then using that time to find how far the Roadrunner has travelled during that time.

First, we need to find the time it takes for the anvil to fall from the cliff. We can use the equation:

d = 1/2 x  g  x t²

where d is the distance (40.0 meters), g is the acceleration due to gravity (9.81 m/s^2), and t is the time.

Solving for t, we get:

t = √(2d/g)

t = √(2 x 40.0/9.81)

t = 2.03 seconds

So it takes 2.03 seconds for the anvil to fall from the cliff to the ground.

During this time, the Roadrunner has travelled a distance equal to its velocity multiplied by the time:

distance = velocity x  time

distance = 10.0 m/s x 2.03 s

distance = 20.3 meters

Therefore, Wile E. Coyote should drop the anvil when the Roadrunner is 20.3 meters away from the cliff.

Answer:

on Pluto or earth go witH u guts mine is always right hope this helps

Answer:

Explanation:

F=ma

F in this case is the gravity acting on the 2kg object. Acceleration of gravity is 9.8 m/s^2. SF=ma, so

F = 2kg*(9.8 m/s^2) = 19.6 N

Now use this force to determine the mass of the object on the table:

F=ma

19.6 N (1N=kg*m/s^2) = m*(1.8 m/s^2)

m = 10.89 kg

Explanation:

Speed multipliers are useful when an object needs to move a further distance or at a higher speed. Some examples are wheels and axles and third class levers. Machines can be either simple or complex. Simple machines are machines that only use one type of machine, such as a lever or an inclined plane.

Answer:

resultant displacement = 20√1o6 km = 205912.6 m in the direction of western north.

Explanation:

assume that the ship started moving from A to B (north at 50km/hr for 2 hours) so the covered distance will be: 50*2 = 100 km

then it moves from B to C so the covered distance will be: 3*60 = 180 km

using Pythagoras, we get the resultant displacement = 20√1o6 km = 205912.6 m in the direction of western north.

Answer:

N = N0 e^-kt          calling k the decay constant

70 = N0 e^-2 kt

35 = N0 e^-15 k

2 = e^(-2 + 15) k

.693 = 13 k

k = .0533

N0 = N e^kt

N0 = 70 e^(.0533 * 2) = 77.87

8.75 = 77.87 e^-(.0533 t)

ln .1124 = -.0533 t

t = -ln .1124 / .0533 = 41 yr

Answer:

It shows the same number of atoms of each element on both sides of the equation

A balanced equation demonstrates the conservation of mass by having the same number of each type of atom on both sides of the arrow.

Explanation:

Matter cannot be created or destroyed in chemical reactions. This is the law of conservation of mass. In every chemical reaction, the same mass of matter must end up in the products as started in the reactants. Balanced chemical equations show that mass is conserved in chemical reactions.

A balanced chemical equation shows that total number of atoms before reaction is equal to total number of atoms after the reaction. As, the total mass of any object lies on its atom, a balanced chemical equation demonstrate the Law of Conservation of Mass.

The Dalton's atomic theory is as follows:

The total number of atoms before and after a reaction are equal, according to a chemical equation that is in balance. A balanced chemical equation illustrates the Law of Conservation of Mass since every object's atom holds the entirety of its mass.

The force is different because of the amount of weight applied so the answer is A

The force that makes a difference in the weight of each person is Gravitational. Correct option is B.

Gravitational force is a fundamental force of nature that exists between any two objects with mass. It's the force that keeps us and everything else on Earth anchored to its surface. This force is proportional to the mass of the objects involved and inversely proportional to the square of the distance between them.

For example, if you were standing on a bathroom scale, the reading on the scale represents the force of the Earth's gravity acting on your body, which is why it's often referred to as your "weight." The actual mass of an object remains constant regardless of its location, but its weight can vary depending on the strength of the gravitational field at different locations (e.g., the weight on the Moon would be less than on Earth due to the Moon's weaker gravitational pull).

The answer option which is an example of the law of multiple proportions is: B) Two different compounds formed from carbon and oxygen have the following mass ratios: 1.33 g O: 1 g C and 2.66 g O: 1 g C.

The Law of Multiple Proportions is also referred to as Dalton's Law and it states that when two chemical elements combine to form more than one chemical compound, the masses (weights) of one chemical element that combine with a fixed mass (weight) of the other chemical element will always be in a ratio of small whole numbers.

According to the Law of Multiple Proportions, when two chemical elements combine to form two different chemical compound, the masses (weights) of one chemical element that combine with 1 gram of the other chemical element can be expressed as a ratio of small whole numbers.

For example, carbon and oxygen react to form either carbon monoxide and carbon dioxide.

Carbon monoxide (CO):

12 grams of C = 16 grams of O.

1 gram of C = 1.33 gram of O.

Carbon dioxide ([tex]CO_2[/tex]):

12 gram of C = 32 grams of O.

1 gram of C = 2.66 gram of O.

Ratio of oxygen (O) = 16:32 = 1:2 (Law of Multiple Proportions).

Answer:

the velocity is 4 ms, if it asked for change it be 0 m/s but its asking for velocity so option 4, 4m/s

Explanation:

The correct answer is Option 2: 2 m/s². The acceleration of the object at 8 seconds is 2 m/s². Note that the negative sign indicates that the acceleration is in the opposite direction of the velocity.

To calculate the acceleration of the object at 8 seconds, we need to look at the change in velocity over time (acceleration is the rate of change of velocity).

Given the graph, we can see that at 8 seconds, the velocity of the object is 6 m/s.

Now, let's find the change in velocity between 8 seconds and 10 seconds:

Change in velocity = Final velocity - Initial velocity

Change in velocity = 2 m/s - 6 m/s

Change in velocity = -4 m/s

Next, find the time interval between 8 seconds and 10 seconds:

Time interval = Final time - Initial time

Time interval = 10 s - 8 s

Time interval = 2 seconds

Now, calculate the acceleration:

Acceleration = Change in velocity / Time interval

Acceleration = (-4 m/s) / (2 s)

Acceleration = -2 m/s²

The correct answer is Option 2: 2 m/s². The acceleration of the object at 8 seconds is 2 m/s². Note that the negative sign indicates that the acceleration is in the opposite direction of the velocity.

Due to paralysis, the result is severe spinal injuries. This is often the case because the spine houses much of the central nervous system, which controls movement. Hence, option C is correct.

You might become paralyzed, and unable to move on your own when something interferes with the nerve impulses that muscles receive from the brain. Strokes, spinal cord injuries, and neurological diseases like multiple sclerosis are among the common causes of paralysis.

When you are unable to move your muscles voluntarily, you are said to be paralyzed. Paralysis results from nerve system issues.

Muscles receive messages from healthy nerves. This causes the muscles to contract. When you’re paralyzed, or have paralysis, you can’t move certain parts of your body.
