Answer:

Quantum mechanics was one of the two great revolutions in modern physics. The first, or Einstein's relativity, was in fact the pinnacle of classical physics. But quantum mechanics and related theories completely changed the world of science and philosophy, and it was the end of classical physics.

Like Einstein relativity, we all use quantum mechanics on a daily basis, but its mathematical principles are very complex and beyond the reach of ordinary people without a degree in physics or mathematics.

In this post, I have tried to make this theory more accessible to all interested loved ones by stating the quantum theory and its consequences for the public.

Magnitude of acceleration

Explanation:

We know that acceleration can increase depending in the force applied on an object, any object with a greater mass will apply a greater force. F = M(a).

Imagine you are holding a box in your hand, the force required for you to hold the box with mass 4.54kg and you want to accelera

svetlana [45]

Answer:

(a) Fₓ = 0 N

$F_y$ = 9.08 N

(b)

(a) Fₓ = 0 N

$F_y$ = 9.08 N

Fₓ = 9.08 N

Explanation:

The magnitude of the force will remain the same in each case, which is given as follows:

F = ma (Newton's Second Law)

where,

F = force = ?

m = mass = 4.54 kg

a = acceleration = 2 m/s²

Therefore,

F = (4.54 kg)(2 m/s²)

F = 9.08 N

Now, we come to each scenario:

(a)

Since the motion is in the vertical direction. Therefore the magnitude of the force in x-direction will be zero:

Fₓ = 0 N

For upward direction the force will be positive:

$F_y$ = 9.08 N

(b)

Since the motion is in the vertical direction. Therefore the magnitude of the force in x-direction will be zero:

Fₓ = 0 N

For upward direction the force will be negative:

$F_y$ = - 9.08 N

(c)

Since the motion is in the horizontal direction. Therefore the magnitude of the force in y-direction will be zero:

$F_y$ = 0 N

Fₓ = 9.08 N

The equation shows neutralization of an acid and a base to produce a salt and water.

Masja [62]

The answer is; 2.

To balance a chemical equation, the moles on one side of the equation has to be the same as that on the other side. This ensures that the law of conservation is observed because matter or energy can't be created or destroyed but can only be transformed from one form to another.

In this equation, putting 2 in front of NaCl ensures that there are 2 moles of Na and CL just as there are 2 moles of Na and CL in the reactants side.

If the child is gaining weight at an expected rate, a child who weighs 36 lb (16.3 kg) at 3 years of age would weigh what amount

algol [13]

The child at 5 years old would weight: 60 lb (27.16 kg) If he continues gaining weight a that rate

To solve this problem we will use a rule of three with the problem information:

3 years-------- 36 lb child's weight

5 years -------- x

Applying the rule of three we get:

x = ( 5 years * 36 lb child's weigh) / 3 years

x = 60 lb

By converting the weight units from lb to kg we have:

x = 60 lb * 16.3 kg/36 lb

x = 27.16 kg

<h3>What is rule of three?</h3>

It describes the proportionality of 3 known data and an unknown data. When you have more than 3 known facts that are involved in the proportionality, it is known as a compound rule. The rule of three is also known as a direct proportions.
