From the calculation and the momentum of the body, the velocity is 62 m/s

<h3>What is momentum?</h3>

The term momentum refers to the product of mass and velocity. Now recall that the rate of change of momentum is equal to the impressed force.

Hence;

7440 kg-m/s = 120 kg * v

v= 7440 kg-m/s/120 kg

v =  62 m/s

Sir Isaac Newton determined that gravity has a fixed acceleration on Earth. The earth pulls objects towards it with a fixed acce
ozzi

A.  Scientific Law.  The mathematics surrounding the acceleration due to gravity is a law.  It is calculated from the universal law of gravity.  However, the explanation of the idea of gravity is a theory.  This falls back to the idea that science is about disproving ideas that we currently believe, rather than proving ideas are correct.  Unless we can disprove an idea, we have to accept the possibility that it is true; the more trials we have of being unable to disprove something, the more accepted it will be.  Yet, no idea can be without doubt and certainty be accepted for what it is.  So, to sum it up, scientific laws are factual descriptions (by formula or word) of phenomenon which always occur given specific conditions.  On the other hand, scientific theories are explanations of the causes underlying these phenomena, the explanation formulated in such a way that they can be disproven.

A basketball player spins the ball with an angular acceleration of 10 rad/s2. What is the ball’s final angular velocity if the b
Lena [83]

Explanation:

It is given that,

The angular acceleration of the basketball, \alpha=10\ rad/s^2

Time taken, t = 3 seconds

We need to find the ball’s final angular velocity if the ball starts from rest. It can be calculated using definition of angular acceleration i.e.

\alpha=\dfrac{\omega_f-\omega_i}{t}

\omega_i=0\ (rest)

\omega_f=\alpha t

\omega_f=10\ rad/s^2\times 3\ s

\omega=30\ rad/s

So, the ball's final angular velocity is 30 rad/s. Hence, this is the required solution.

Describe and give an example of mutualism.
Slav-nsk [51]

Answer:

Mutualism, commensalism, parasitism, competition, and predation.

Explanation:

mutualism- relationship between two or more organisms where both are benefited. Example-oxpecker with rhino/zebra. They eat bugs off of them which means that they are getting food, while the rhino/zebra are getting cleaned up with pest control.

commensalism- relationship between two organisms where one benefits and the other isn't benefited or harmed. EX- tree frogs use plants as protectioin.he frog is benefited, and the plant is neither harmed nor benefited. Remora fish have a disk on their heads that they use to attach themselves to larger animals for protection. The animals they attach to are neither harmed nor benefited.  

parasitism- in a relationship where an organism benefits at the expense of the other. (one is benefited while the other is harmed) ex- fleas and ticks that live on cats and dogs, tape worms that live in people and animals that eat the food which means that the people aren't getting the food or nutrition that they eat. lice, etc

competition- interaction within organisms/species in which both the organisms/species are harmed and is apart of natural selection. Examples may include two males fighting over a mate, animals competing over food, limited habitats that they are fighting over, territory, etc.

predation- the preying of one animal on another. It's where the predator hunts and eats another organism which is its prey. categorized within-(1) carnivory, (2) herbivory, (3) parasitism, and (4) mutualism. Each type of predation can by categorized based on whether or not it results in the death of the prey.ex- owls hunting mice, wolves hunting rabbits, lion hunting gazelle, etc.
