**Answer 1**

Answer:

1000 cm³

Explanation:

The product of powers property is a rule that helps in simplifying the difficulties that comes with multiplying powers of numbers. It states that when multiplying two powers having the same base, we take one of the base, and then just add the exponents.

This is illustrated in the example.

S¹ * S². The product of powers asks us to pick one of the bases, S, and then add up the powers, thus

S¹ * S² = S^(¹+²)

S¹ * S² = S³

Now, using this in our question, volume of the cube is S³. Since we aren't given a length, I'm going to assume a length.

L = 10 cm. We all know that all sides are equal in a cube,

So, S = 10 cm.

S³ = volume of the cube

V = 10³

V = 1000 cm³

Now, to test the property of products, we say

S = 10, even though it doesn't show any visible exponent, we know that it's raised to the power of 1, and thus

S = 10¹

V = S * S * S

V = 10¹ * 10¹ * 10¹

V = 10^(¹+¹+¹)

V = 10³

V = 1000 cm³

One particle has mass m and a second particle has mass 2m. The second particle is moving with speed v and the first with speed 2v. How do their kinetic energies compare?

### Answers

**Answer:**

**Explanation:**

The formula for kinetic energy to be used here is 1/2mv².

If the first particle is "particle a" and the second particle is "particle n"; there kinetic energies (K.E) will be

K.Eₐ = 1/2.m2v² = **mv²**

K.Eₙ = 1/2.2mv² = **mv²**

From the above, it can be said that there kinetic energies are the same.

NOTE that the m and v used in the question means mass and velocity respectively.

A 56 kg woman climbs the stairs to a height of 5 m. Determine: a) what mechanical work

she performed; b) what work the woman will do when climbing the stairs and carrying a 5 kg load.

### Answers

**Answer:**

a) W = 2746.8[J]

b) W = 2992.05 [J]

**Explanation:**

Work is defined as the product of force by distance. We must bear in mind that the force that performs the work is the one that acts in the same direction of displacement.

For this case, we must calculate the weight of the woman, the weight is defined as the product of mass by gravity.

[tex]w=m*g\\[/tex]

where:

w = weight [N] (units of Newtons]

m = mass = 56 [kg]

g = gravity acceleration = 9.81 [m/s²]

[tex]w=56*9.81\\w=549.36[N][/tex]

a)

[tex]W=F*d[/tex]

where:

F = weight = 549.36[N]

d = distance = 5 [m]

[tex]W = 549.36*5\\W = 2746.8[J][/tex]

b)

The new mass will be the combination of the mass of the woman plus that of the load.

[tex]m_{new} = 56+5\\m_{new}=61[kg][/tex]

[tex]w_{new}=61*9.81\\w_{new}=598.41[N][/tex]

"When landing after a spectacular somersault, a 55.0 kg gymnast decelerates by pushing straight down on the mat. Calculate the force (in N) she must exert if her deceleration is 6.00 times the acceleration of gravity."

### Answers

**Answer:**

See the explanation below.

**Explanation:**

Of course yes, after my explanation you will understand very well how to analyze this type of problems.

First, we must differentiate the weight of the mass, the mass has units of kilograms or pounds, while the weight is the product of the mass by gravitational acceleration. In this way, we have the following formula for the weight of anybody.

w = m*g

where:

w = weight [N] (units of Newtons]

m = mass [kg]

g = gravity acceleration = 9.81 [m/s²]

When we have the product of these units [kg]*[m/s²], We are always going to get as a result the units of Newtons [N], The Newton is a unit of force.

Now, to solve this problem we must use Newton's second law, which tells us that the sum of forces on a body must be equal to the product of mass by acceleration.

ΣF = m*a

where:

ΣF = forces acting over the gymnast [N]

m = mass = 55 [kg]

a = desacceleration = 6*9.81 = 58.86 [m/²]

Now we have two forces acting over the gymnast the first one is his or her weight (the mass by the gravity acceleration) and the second force is the one made it by his or her legs upwards in order to be standing. Let's take as positive signs the movements and forces upwards and negative downwards

- (m*g) + Fl = m*a

where:

Fl = force made it by the legs [N]

As the deceleration is upward because it prevents the person from continuing to go down, it is taken as a positive sign.

- (55*9.81) + Fl = (55*58.86)

Fl = (55*58.86) + (55*9.81)

Fl = 3776.85 [N]

I hope you can understand :)

How high will the stones go? Show all your work

### Answers

**Answer:**

**a) t = 6.62 s**

**b) x = 238.6 m**

**c) H = 53.7 m**

**Explanation:**

a) We can find the time of flight as follows:

[tex] y_{f} = y_{0} + v_{0_{y}}t - \frac{1}{2}gt^{2} [/tex]

Where:

[tex]y_{f}[/tex] is the final height = 0

[tex]y_{0}[/tex] is the initial height = 0

[tex]v_{0_{y}}[/tex] is the initial vertical velocity of the stone

t: is the time

g: is the gravity = 9.81 m/s²

[tex] v_{0}sin(42)t - \frac{1}{2}gt^{2} = 0 [/tex]

[tex] 48.5 m/s*sin(42)*t - \frac{1}{2}9.81 m/s^{2}*t^{2} = 0 [/tex]

By solving the above quadratic equation we have:

t = 6.62 s

b) The maximum range is:

[tex] x = v_{0_{x}}t = 48.5 m/s*cos(42)*6.62 s = 238.6 m [/tex]

c) The maximum height (H) can be found knowing that at this height the final vertical velocity of the stone is zero:

[tex] v_{f_{y}}^{2} = v_{0_{y}}^{2} - 2gH [/tex]

[tex] H = \frac{v_{0_{y}}^{2} - v_{f_{y}}^{2}}{2g} = \frac{(48.5 m/s*sin(42))^{2} - 0}{2*9.81 m/s^{2}} = 53.7 m [/tex]

### Answers

**Answer:**

θ₁ = 5.4°

Gravity pushes against all objects, trying to crush it. What pushes against gravity in: a main sequence star, a white dwarf, a neutron star, and a black hole?

### Answers

**Answer:**

heat pressure, neutron degeneracy, electron degeneracy,nothing.

**Explanation:**

In main sequence star, gravity's inward pull is greatly balanced by the heat pressure. In the white dwarf, gravity is mainly balanced by the electron degeneracy pressure that arises from the fact that the electrons are fermions and they obey the Pauli's exclusion principle. So there is no two electrons that have the same the four quantum numbers.

While in neutron star, the neutron degeneracy pressure obeys the Pauli's exclusion principle that gives rise to the degeneracy pressure and noting pushes against the gravity in the black hole. Therefore the correct option is the heat pressure, neutron degeneracy, electron degeneracy and nothing.

A boy on a bicycle rides in a circle of radius ro at speed vo. If the boy now rides at a radius equal to half the initial radius ro, by what approximate factor must he change his speed in order to have the same radial acceleration

### Answers

**Answer:**

**The speed must change by **[tex]\frac{1}{\sqrt{2}}[/tex]** factor in order to have the same radial acceleration.**

**Explanation:**

The radial or centripetal acceleration is given by:

[tex] a_{c} = \frac{v^{2}}{r} [/tex]

Where:

v: is the speed = v₀

r: is the radius = r₀

[tex] a_{c} = \frac{v_{0}^{2}}{r_{0}} [/tex] (1)

If the radius is now equal to half the initial radius the speed must be:

[tex]a_{c} = \frac{v^{2}}{r_{0}/2}[/tex] (2)

By equating equation (1) and (2):

[tex] \frac{v_{0}^{2}}{r_{0}} = \frac{v^{2}}{r_{0}/2} [/tex]

[tex]v^{2} = \frac{v_{0}^{2}}{2}[/tex]

In 1926 Babe Ruth hit a home run that was estimated to have landed 180. meters from home plate and to have reached a height of 21.3 meters. What was the initial velocity of the ball?

### Answers

**Answer:**

v = 47.85 m / s, θ = 64.7º

**Explanation:**

This is a missile throwing exercise.

Let's find the speed to reach the maximum height, at this point the vertical speed is zero

[tex]v_{y}^{2}[/tex] = v_{oy}^{2} - 2 g y

0 = v_{oy}^{2} - 2gy

v_{oy} = √2gy

let's calculate

v_{oy} = √ (2 9.8 21.3)

v_{oy} = 20.43 m / s

now we can calculate the time it takes to get to this point

vy = v_{oy} - g t

t = v_{oy} / g

t = 20.43 / 9.8

t = 2.08 s

in projectile launching, the time it takes for the body to rise is the same as the time it takes to go down, so the total launch time is

[tex]t_{v}[/tex] = 2 t

t_{v} = 2 2.08 = 4.16 s

let's use the horizontal throw ratio

x = v₀ₓ t_{v}

v₀ₓ = x / t_{v}

v₀ₓ = 180 / 4.16

v₀ₓ = 43.27 m / s

initial velocity is

v = √ (v₀ₓ² + v_{oy}^{2})

v = √ (20.43² + 43.27²)

v = 47.85 m / s

with an angle of

tan θ = I go / vox

θ = tan⁻¹ (43.27 / 20.43)

θ = 64.7º

If one person is applying an upward force equal to 60 N at one end, at what location on the board is the other person applying an upward force

### Answers

**Answer:**

When one person applies force f1 = 60 N at one end, the other person applies f2 = 160 - 60 = 100 N. The torques about the center must balance. Thus the distances from the center d1 and d2 must be such that f1*d1 = f2*d2, or 60*1.5 = 100*d2, so d2=0.9. Thus f2 must be applied at a point 1.5 + 0.9 = 2.4 m from the end where f1 is applied.
