what is the weight of a box that has a mass of 25 kg?​

Answers

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

a wagon has a mass of 100 kg an acceleration of 2m/s/s. What is the force on the wagon?

Answers

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

A dog starts at position x=2.50m, and undergoes a displacement of 8.25m. What is its final position?

Answers

Answer:

Civil law deals with behavior that constitutes an injury to an individual or other private party, such as a corporation. Examples are defamation (including libel and slander), breach of contract, negligence resulting in injury or death, and property damage.

Explanation:

Displacement is how far the dog is from its original position so use, addition initial + displacement = final
2.50+8.25=10.75

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.

Answers

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 caused the original creation of the Universe? How do we find out?

Answers

The Big Bang theory is the prevailing cosmological description of the development of the universe. According to estimation of this theory, space and time emerged together 13.799±0.021 billion years ago and the energy and matter initially present have become less dense as the universe expanded.At first, the universe was too hot and dense for particles to be stable, but then the first quarks formed, which then grouped together to make protons and neutrons, and eventually the first atoms were created. After about 500 million years, the first stars, galaxies and black holes began to take shape.

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?

Answers

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]

[tex]Q=2*4180*5\\Q=41800[J][/tex]

Can there be displacement of an object in the absence of any force acting on it? Think, Discuss it with your friends and teacher?

Answers

Answer:

An object can have a displacement in the absence of any external force acting on it

Explanation:

When a object moves with a constant velocity (v), then it gets displaced in the direction of motion but the net external force experienced by the object is zero.

F  external  =ma

If object moves with constant velocity, acceleration is zero.

Since, a=0  ⟹F  external  =0

Using  s=ut+  1/2 at  ^2

 ⟹    Displacement    s=ut    (∵a=0)

Hence, an object can have a displacement in the absence of any external force acting on it

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?

Answers

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.

10.0 J

if it was 10.01 it would be significant, but its 10.0 which makes it a whole number

All zero's preceding the first integers are never significant. For example: 0.0078 has two significant figures. All zero's after the decimal point are always significant. For example: 4.500, 45.00 and 450.0 all have four significant figures
