I need help with the following three physics problems please!

omeli [17]

None of these is a Physics problem. The numbers, and the fractions that
they appear in, might have come from Physics problems, but these are
nothing more than arithmetic exercises, and they can be whipped out
in a hurry with a little bit of fancy calculator work. You don't have to
know any Physics in order to answer any of these.

The first one is 2.7 x 10⁻²⁴ Newton.

Which of the following statements can be concluded (deducted) from the parallel-axis theorem? The area moment of inertia of an a

Ratling [72]

Answer:

The statement that we can conclude is that the moment of inertial of any body about the centroidal axis is least of all the moment of inertia's of the body about any arbitrary axis in the body.

Explanation:

According to parallel axis theorem we have

$I_{x}=I_{C.G}+Ax^{2}$

Where

$I_{x}$ is the moment of inertia about any arbitrary axis.

$I_{C.G}$ is the moment of inertia about centroidal axis.

A is the area of section of which Moment of area is evaluated

'x' = is the distance between the axis and C.G

thus we conclude that $I_{C.G}$ is least of all the moments.

maw [93]

Answer:

Its gravitational potential energy must increase.

Explanation:

<u>Conservation of Mechanical Energy</u>

The total amount of mechanical energy, in a closed system in the absence of dissipative forces like friction or air resistance, remains constant.

This means that energy cannot disappear or appear and that potential energy can become kinetic energy or vice versa.

In a closed system like a pendulum, two types of energies are considered: Gravitational potential (U) and kinetic (K). Thus, the sum of both energies must remain constant in time.

Suppose the pendulum is at a state where U=150 J, and K=350 J. The total mechanical energy is:

M = 150 J + 350 J = 500 J

If the kinetic energy decreases to a new value, say K = 200 J, then the gravitational potential must increase to compensate for this new condition, that is: U = 300 J

So, It's gravitational potencial energy must increase

Hope it helps you I'm from ph :)

A man with mass 81 kg lies on the floor. what is the normal force on the man?

butalik [34]

Answer:

Forces come in pairs, so the force of gravity (9.8 N) with the mans weight (794N) on the earth is counteracted with the normal force ( the force of the earth back on the man) which is the same

Two large metal plates of area 1.2 m^2 face each other, 6.5 cm apart, with equal charge magnitudes but opposite signs. The field

andrey2020 [161]

Answer:

Q= 722.5 *10⁻¹² C

Explanation:

Conceptual analysis

For a parallel plate capacitor, we can use the following formula :

E= (Q) /(ϵ₀*A) Formula (1)

Where:

E: electric field between the plates ( N/C)

Q: Charge of the plates (C)

ϵo : vacuum permittivity ( C²/ N.m²)

A : area oh the plates (m²)

Known data

A = 1.2 m²

E= 68 N/C

ϵo= 8.8542*10⁻¹² ( C²/ N.m²)

Problem development

We apply the formula (1) :

$68= \frac{Q}{(8.8542*10^{-12} )(1.2)}$

Q= (68) (8.8542*10⁻¹²)(1.2)

Q= 722.5 *10⁻¹² C
