<h2>Answer:</h2>

Deductive reasoning

<h2>Explanation:</h2>

The process of using pre-existing knowledge to make logical conclusions, make predictions and draw out explanations is called reasoning. Reasoning are basically of two types:

i. Deductive reasoning: This takes a general rule, idea, or theory as foundation and then proceeds from there to draw meaningful conclusions or predictions. For example;

           <em>  If a = 3                ----------------(i)</em>

<em>              And b = 5           ----------------(ii)</em>

<em>              Then 2a + 4b = 26 -------------(iii)</em>

From above, following from equations (i) and (ii), it can be concluded that (iii) should be true.

ii. Inductive reasoning: While deductive reasoning moves from a general rule to specific rule, inductive reasoning does the opposite - moves from specific to a general rule.

An object is at rest on the ground. The object experiences a downward gravitational force from Earth. Which of the following pre
Montano1993 [528]

Answer:

A) and B) are correct.

Explanation:

If the object is at rest, it means that no net force is exerted on it.

As the object experiences a downward gravitational force from Earth, in order to be at rest, it must experience an upward force with the same magnitude as the gravitational force on the object.

This force is supplied by the normal force, which can adopt any value in order to meet the condition imposed by Newton´s 2nd Law, and is always perpendicular to the surface on which the object is placed (in this case, the ground).

At a molecular level, this normal force is supplied by the bonded molecules of the ground that behave like small springs being compressed by the molecules of the object, exerting an upward restoring force upward on them.

So, the statements A) and B) are true.

a ball rolls off the edge of a 2m high shelf at a speed of 5 m/s and hits the ground the taken to hit the ground is
RUDIKE [14]

Answer:

Explanation:

Use the one-dimensional equation

Δx = v_0t+\frac{1}{2}at^2 where delta x is the displacement of the object, v0 is the velocity of the object, a is the pull of gravity, and t is the time in seconds. That's our unknown.

Δx = -2 (negative because where it ends up is lower than the point at which it started),

v_0=5, and

a = -9.8

Filling in:

-2=5t+\frac{1}{2}(-9.8) t^2 and simplified a bit:

-2=5t-4.9 t^2

this should look hauntingly familiar (a quadratic, which is parabolic motion...very important in physics!!). We begin by getting everything on one side of the equals sign and solving for t by factoring:

-4.9 t^2+5t+2=0 (the 0 is also indicative of the object landing on the ground! Isn't this a beautiful thing, how it all just works so perfectly together?)

When you factor this however your math/physics teacher has you factoring you will get that

t = 1.3 sec and t = -.31 sec

Since we all know that time can NEVER be negative, it takes the ball 1.3 sec to hit the ground from a height of 2 m if it is rolling off the shelf at 5 m/s.

A car with a mass of 600 kg is traveling at a velocity of 10 m/s. How much kinetic energy does it have?
Viefleur [7K]

Answer:

KE = 30,000 J

Explanation:

KE = \frac{1}{2} mv²

KE = \frac{1}{2} (600)(10)²

KE = \frac{1}{2} (600)(100)

KE = \frac{1}{2} (60000)

KE = 30,000 J

What is the difference between the formation of an ionic bond and formation of a covalent bond?
Vikentia [17]

Answer:

Answer to the question:

Explanation:

Differences between ionic bond and covalent bond:

The ionic bond occurs between two different atoms (metallic and non-metallic), while the covalent bond occurs between two equal atoms (non-metallic).

In the covalent bond there is an electron compartment, while in the ionic bond there is an electron transfer.

Ionic bonds have a high melting and boiling point, while covalent bonds usually have a low point.
