a wagon has a mass of 100 kg an acceleration of 2m/s/s. What is the force on the wagon?
Answer:
200N
Explanation:
Given parameters:
Mass of wagon = 100kg
Acceleration = 2m/s²
Unknown:
Force on the wagon = ?
Solution:
From Newton's second law of motion:
Force = mass x acceleration
Now insert the parameters and solve;
Force = 100 x 2 = 200N

Do you believe that global warming is happening? Tell why or why not. If you believe global warming is happening, what can we do to slow it down?
Answer:
Yes I do believe global warming is happening, mainly because there is a plethora of data and research from scientists to support the claim. The effects of global warming around us are clearly observed as well, such as the rise in acidity in the oceans. Another example is in the Artic, where a natural occurence takes place. Ice freezes and cold salty water takes its place, and because of it's high density it sinks and sweeps across the ocean floor. That cold water is then replaced by warmer water, and this is called the global ocean conveyor belt. As seen through the example with the Artic, ocean temperature plays a key role in the conveyor belt. Climate change is fueled through human activities, which could harm the system. If one part of the conveyor belt were to break down, such as the one in the Artic, nutrients will not be distributed to start the food chain. Organisms such as phytoplankton need those nutrients to thrive. If phytoplankton are endangered, all life in the oceans is endangered. So as we can see, global warming is extremely harmful to the environment and it's effects are observed around us.
To slow global warming down we should consume less meat, and go to vegan or vegetarian diets. Your carbon footprint is halved by consuming less meat and eating a more vegan or vegetarian diet. Another thing is that we as a society should stop using so much plastic. It takes more than a century to degrade, most landfills are composed of it. Microplastics also get into our oceans, and our fish end up consuming them.

explain why smoke particles in air move about faster if the temp of the air is increased??
Answer:
kinetic energy increases with the energy which causes the particles to move faster resulting in increases collision rates and rate of diffusion.
Explanation:
The increase in temperature of the air causes the air molecules to have more kinetic energy, which leads to more frequent and forceful collisions with the smoke particles. This, in turn, causes the smoke particles to move faster through the air.
What is kinetic energy?Kinetic energy is the energy an object possesses due to its motion. Any object that is in motion has kinetic energy, and the amount of kinetic energy it has depends on its mass and velocity.
The formula for calculating kinetic energy is:
KE = 1/2 × m × v²
where KE represents kinetic energy, m represents the mass of the object, and v represents the velocity of the object.
Here in the question,
Smoke particles in the air move around due to collisions with air molecules. When the temperature of the air increases, the average kinetic energy of the air molecules also increases. This means that the air molecules are moving faster and colliding more frequently with the smoke particles.
The smoke particles themselves do not have an increase in kinetic energy, but they do receive more energy from the collisions with the air molecules. This extra energy causes the smoke particles to move faster and more erratically, making them more dispersed throughout the air.
In addition, when air is heated, it becomes less dense. This means that there are fewer air molecules in a given volume of air. As a result, the smoke particles have more space to move around and collide with air molecules, which further contributes to their increased speed and movement.
Therefore, increasing the temperature of the air increases the speed and frequency of collisions between the air molecules and smoke particles, leading to the smoke particles moving faster and more widely dispersed throughout the air.

The visible light spectrum is the segment of the electromagnetic spectrum that the human eye can view. More simply, this range of wavelengths is called visible light. Typically, the human eye can detect wavelengths from 380 to 700 nanometers.
A man standing on top of a 30 m tall building throws a brick downwards with a velocity of 12 m/s. Determine the speed of the brick just before it hits the ground.
Answer:
27.1m/s
Explanation:
Given parameters:
Height of the building = 30m
Initial velocity = 12m/s
Unknown:
Final velocity = ?
Solution:
We apply one of the kinematics equation to solve this problem:
v² = u² + 2gh
v is the final velocity
u is the initial velocity
g is the acceleration due to gravity
h is the height
v² = 12² + (2 x 9.8 x 30)
v = 27.1m/s
what is the weight of a box that has a mass of 25 kg?
Answer:
Explanation:
The weight of an object is a measurement of how hard a force(in our case gravity) is pulling on an object. so W = mg, where W - is the weight. in our case W is G (Gravitational force) So G = mg => m = G/g => m = 25/9.8 => m = 2.5 kg. If you're problem states that weight is measured in kg, then it is definitely wrong. Weight is measured in Newtons and mass in kg. There are different system of units like gravitational,SI, MKS. I have seen in some text as slug as the unit of mass in gravitational system.So mass of 25 kg weight is 25/9.81 slug of mass.
Answer:
245.18 newtons
Explanation:
For example,
10 kg times 9.8 N/kg equals
98 N.

A girl during a hike has a bottle of mineral water in her haversack. The bottle has 2 litres of water in it (2ltr. weigh 2kg). The water gets heated by the sun by 5 °C. How much heat has the water absorbed from the sun?
Answer:
Q = 41800[J]
Explanation:
These types of problems can be solved using the following heat transfer equation for quarps that increase or decrease their temperature as a function of mass.
[tex]Q=m*C_{p}*DT[/tex]
where:
Q = Heat absorbed [J]
m = mass = 2 [kg]
DT = temperature change = 5 [°C]
Cp = specific heat of the water = 4180 [J/kg*°C]
