Dog C will win the toy who is pulling to the east with a force of 40 N.

A force is an effect that can alter an object's motion according to physics. An object with mass can change its velocity, or accelerate, as a result of a force. An obvious way to describe force is as a push or a pull. A force is a vector quantity since it has both magnitude and direction.

Dog C, the first two cancel each other out since their pulling two opposite ways with the same force, the only force left is 40 N east so dog C would win.

Answer:

Box 1 and Box 2 are the same mass It caused both to change speed because they have both the same mass.

Explanation:

The work input = Fi × di

To solve for work input, you need to know the force acting on an object and the distance it moves in the direction of the force. Work input is defined as the product of force and distance, given by the formula:

Work Input = Force × Distance × cosθ

Where θ is the angle between the force vector and the direction of motion. If the force is applied in the direction of motion, then θ = 0 and cosθ = 1, so the formula simplifies to:

Work Input = Force × Distance

For example, if you are pushing a box with a force of 50 newtons over a distance of 10 meters, the work input would be:

Work Input = 50 N × 10 m × cos(0°) = 500 Joules

Answer: An ecosystem is a community of plants and animals and their physical surroundings

Explanation: An ecosystem is a geographic area where plants, animals, and other organisms as well as weather and landscape work together to form a bubble of life. Ecosystems contain biotic and abiotic factors both. Biotic factors include plants, animals, and other organism

Answer: An ecosystem is a community of plants and animals and their physical surroundings.

Explanation: Ecosystem plays an essential role for the existence of living organisms in the planet Earth. A balanced ecosystem is attained as a result of various reasons it includes the live ratio of diverse varieties of organisms in a particular ecosystem, necessary physical, biological, and chemical conditions that promotes the living of organisms, and the balanced atmosphere attained as the result of temperature, wind, and humidity.

As all the above mentioned properties are necessary for maintaining a sustainable ecosystem, it is clearly understood that an ecosystem is a community of plants and animals and their physical surroundings.

Answer: The Eiffel Tower is primarily made of iron. Gustave Eiffel, the French engineer who designed and oversaw the construction of the tower, used wrought iron to build its frame. In total, the tower contains about 18,000 individual iron pieces and weighs over 10,000 tons. The iron framework is held together by 2.5 million rivets. The tower's base is made of concrete, and the top portion of the tower is covered in bronze plates.

Answer:

Increase the mass or velocity.

Explanation:

The formula of Kinetic Energy is Ek=1/2*m*v^2. So both increase the mass or velocity can increase the Ek.

Kinetic energy of an object depends on its  mass and velocity. Therefore, the roller caster can gain more kinetic energy by increasing its velocity. Increase in mass by loading the cart can also helps to increase its kinetic energy.

Kinetic energy of an object is generated by virtue of its motion. Whereas, the when the object is at rest, the energy is stored in the form of potential energy.

The kinetic energy of a body is depends on its mass and velocity as per the relation written below:

KE = 1/2 Mv²

Hence, an increase in velocity increases  the kinetic energy by 4 times. Similarly an increase in mass also increases the kinetic energy.

Therefore, by increasing its speed and loading more mass, the roller coaster can gain more kinetic energy. Moreover, the way can be more smoothened to avoid the chance of friction.

Answer:

The answers are the options 1, 2, 3, and 4

Explanation:

If you have any questions ask me please! :)

The kinetic Energy of the bottle falling from a height of 0.8m for different masses of (0.125,0.250,0.375,0.500)kg is (1,2,3,4) kgm*2/s*2 respectively.

Let's calculate the kinetic energy for different masses having a velocity of 4m/s in each case,

Using Formula:

K.E=\(1/2mv^{2}\)

When the mass of the bottle is 0.125 kg, the Kinetic Energy is

K.E=\(1/2(0.125)(4)^{2}\)

K.E=\(1/2(0.125)(16)\)

K.E=1/2(2)

K.E=1

When the mass of the bottle is 0.250 kg, the Kinetic Energy  is

K.E=\(1/2(0.250)(4)^{2}\)

K.E=1/2(0.125)(16)

K.E=1/2(4)

K.E=2

When the mass of the bottle is 0.125 kg, the Kinetic Energy is

K.E=\(1/2(0.375)(4)^{2}\)

K.E=1/2(0.375)(16)

K.E=1/2(6)

K.E=3

When the mass of the bottle is 0.500 kg, the Kinetic Energy  is

K.E=\(1/2(0.500)(4)^{2}\)

K.E=1/2(0.500)(16)

K.E=1/2(8)

K.E=4

Now we can calculate the change in kinetic energy (ΔKE):

ΔKE = KE(final) - KE(initial)

= 4 kg m*2/s*2 - 1 kg m*2/s*2

= 3 kg m*2/s*2

D. It takes more force to move something that has more mass.

Explanation:

In the equation force and mass are directly related, so more mass means more force needed.

Think about this, you are applying 10 N force to move a car vs a tiny box. Which will move faster? From your experience, you know that light things move faster thus your box will move faster than car. Thus, to move something like car you will need more force.
