In order for an object to accelerate, a forcegravityfrictiona swing must be applied.

Answers

In order foran object to accelerate, a force must be applied. It follows Newton’s secondlaw of motion where it states that a body at rest remains at rest unless aforce is acted upon it. When you move an object, you are exerting a force ontoit. By exerting a force on the object, you are actually displacing it from itsinitial position. You cannot apply force to the object without altering itsposition. Keep in mind that when you exert work, you are exerting energy too. 

Ifyou left a board lying in the grass for a few days, what would happen to the
grass underneath the board? Why?

Answers

The grass would die (turn brown/yellow). This is because the grass has not received any sunlight. This means it cannot photosynthesise and make glucose (food) which it needs to survive.

Imagine that a tank is filled with water. The height of liquid column is 7 meters and the area is 1.5 square meters (m2). What's the force of gravity acting on the column of water?

Answers

-- The volume of water is    (1.5 m² x 7 m)  =  10.5 m³

   10.5 m³  =  10,500 liters

   Water mass  =  (10,500 liters) x (1 kg/liter) = 10,500 kg.

-- "Force of gravity on the water"

    =  Weight of the water = (10,500 kg) x (9.8 m/s²) = 102,900 newtons

-- Pressure on the bottom of the tank =

                 (102,900 newtons) / (1.5 m²)

             =      68,600 nt/m²  =  68,600 pascal .

your answer is 102,900 N

What is the law of inertia?

Answers

Inertia: Objects tend to move at the same speed and direction or, if at rest, stay at rest. A force has to be applied to overcome inertia. An objects inertia is determined by the mass of the object.

Answer:

The law of inertia is mostly known the same as THE NEWTONS FIRST LAW OF MOTION which states that"A body will continue to its state of rest or motion unless acted by an external forces"

●WHAT IS INERTIA?

Inertia is the ability of a body at rest to resist motion or a body in motion to resist resting unless acted by external forces.

△TYPES OF INERTIA

■There are 3 types of inertia,

◎Inertia of rest

◎Inertia of direction

◎Inertia of motion

Imagine you are holding an apple. Does this apple have energy?how do you know?

Answers


-- The apple has heat energy.  If its temperature were Absolute Zero,
then the skin on my hand would freeze instantly and fall off.

-- The apple has potential energy, relative to the ground.  If I were to
release it out of my hand, gravity would do work on it and pull it with
some speed to the ground, where it would have the kinetic energy to
break some blades of grass and dig a small crater in the soil.

-- The apple has chemical energy which, if I were to expose it to
human digestion and metabolism by eating it, would change to
glucose, soak into my muscles, and make itself available to me
whenever I need vim and vigor, mental alertness, visual acuity,
and the wherewithal to to escape any unexpected beast that might
in turn set upon me with the intention of converting MY entire person
into food energy for its own use.

Which equation describes the sum of the two vectors plotted below?

Answers

Final answer:

The sum of two vectors A and B is a resultant vector R, where R = A + B. If vectors A and B are plotted with their tails at the origin and heads at points (x1, y1) and (x2, y2), respectively, the resultant vector R ends at point (x1+x2, y1+y2). This represents the sum of the individual components of vectors A and B.

Explanation:

In vector addition, the equation for the sum of two vectors A and B can be generally represented as R = A + B, where R is the resultant vector. If the vectors are plotted with their tails at the origin and their heads ending at points (x1, y1) for Vector A and (x2, y2) for Vector B, the resultant vector, R, will end at the point (x1+x2, y1+y2). In other words, the components of the resultant vector are simply the sum of the components of the original vectors.
