The weight of the block is ( Fo g ) / ( g + 3 a )

\texttt{ }

<h3>Further explanation</h3>

Newton's second law of motion states that the resultant force applied to an object is directly proportional to the mass and acceleration of the object.

\large {\boxed {F = ma }

F = Force ( Newton )

m = Object's Mass ( kg )

a = Acceleration ( m )

Let us now tackle the problem !

\texttt{ }

<u>Given:</u>

mass of block = M

acceleration of block = 3a

constant force = Fo

<u>Asked:</u>

weight of block = w = ?

<u>Solution:</u>

We will use Second Law of Newton as follows:

\Sigma F = ma

Fo - Mg = M(3a)

Fo = Mg + 3Ma

Fo = M(g + 3a)

M = Fo \div ( g + 3a )

\large{ \boxed{M = \frac{Fo}{g + 3a}}}

\texttt{ }

w = Mg

w = \frac{Fo}{g + 3a} \times g

\large {\boxed {w = Fo \times \frac{g}{g + 3a}}}

\texttt{ }

Answer:

The mass of the block, M =T/(3a +g)  Kg

Explanation:

Given,

The upward acceleration of the block a = 3a

The constant force acting on the block, F₀ = Ma = 3Ma

The mass of the block, M = ?

In an Atwood's machine, the upward force of the block is given by the relation

                                     Ma = T - Mg

                                      M x 3a = T - Ma    

                                    3Ma + Mg = T

                                       M = T/(3a +g)  Kg

Where 'T' is the tension of the string.

Hence, the mass of the block in Atwood's machine is, M = T/(3a +g)  Kg

Give the correct balanced equation for the single replacement reaction of magnesium with aluminum oxide
diamong [38]

Answer:

Al2O3 + 3Mg ===》 3MgO + 2Al

Explanation:

Reaction of aluminium oxide with magnesium metal would form magnesium oxide and aluminium metal.

Balancing the stoichiometric equation, the number of atoms at the reactant must be equal to the number of atoms at the product so that law of conservation of matter must hold.

Al203 + 3Mg ====》 3MgO + 2Al

2 aluminium at reactant = 2 aluminium at product

3 oxygen at reactant = 3 oxygen at product

3 magnesium at reactant = 3 magnesium at product.

A reactor operating at 1 MW is scrammed by instantaneous insertion of $5.00 of negative reactivity. Approximately how long does
Novosadov [1.4K]

Answer:

time is 3333.33 min or 55.55 hr

Explanation:

given data

reactor operating = 1 MW

negative reactivity =  $5

power = 1 miliwatt

to find out

how long does it take

solution

we know here power coefficient that is

power coefficient = \frac{10^{6} }{10^{6} }

power coefficient = 1

so time required to reach power is

power =  reactivity × time / power coefficient + reactor operating

1 × 10^{-3} = -5 t / 1  +  1 × 10^{6}

5t =  10^{6} - 10^{-3}

t = 199999.99 sec

so time is 3333.33 min or 55.55 hr

Suppose you throw a baseball downward from a roof so that it initially has 120 J of gravitational potential energy, and 10 J of
Volgvan

Answer:

B.

It will be greater than 10 J.

Explanation:

The total mechanical energy of an object is the sum of its potential energy (PE) and its kinetic energy (KE):

E = PE + KE

According to the law of conservation of energy, when there are no frictional forces on an object, its mechanical energy is conserved.

The potential energy PE is the energy due to the position of the object: the highest the object above the ground, the highest its PE.

The kinetic energy KE is the energy due to the motion of the object: the highest its speed, the largest its KE.

Here at the beginning, when it is at the top of the roof, the baseball has:

PE = 120 J

KE = 10 J

So the total energy is

E = 120 + 10 = 130 J

As the ball falls down, its potential energy decreases, since its height decreases; as a result, since the total energy must remain constant, its kinetic energy increases (as its speed increases).

Therefore, when the ball reaches the ground, its kinetic energy must be greater than 10 J.
