Explanation:

Answer:

1,250 newtons

Explanation:

F=MA

first we find acceleration which is in other words "the change in velocity over time"

so we know it changes velocity in 4 seconds. the velocity increases by 5.

we shall now divide 5 by 4 which equals 1.25m/s/s

now we can solve the net force:

Fnet= (1.25m/s/s)(1,000kg)

so our net force is 1,250N

The principal axes are the coordinate axes (x, y, z), and the principal moments of inertia are 23mb^2, 20mb^2, and 20mb^2 for the x, y, and z axes, respectively.

To find the inertia tensor, principal axes, and principal moments of inertia for the three-particle system, we need to calculate the inertia tensor and diagonalize it.

The inertia tensor is given by the formula:

I_ij = Σ(m_k * (δ_ij * r_k^2 - r_ki * r_kj))

where I_ij is the (i,j)-th element of the inertia tensor, m_k is the mass of the k-th particle, δ_ij is the Kronecker delta, r_k^2 is the square of the distance from the k-th particle to the origin, and r_ki and r_kj are the components of the position vector of the k-th particle.

Let's calculate the inertia tensor for the given system:

I_xx = 3m * (0^2 + b^2 + b^2) + 4m * (0^2 + b^2 + (-b)^2) + 2m * (b^2 + (-b)^2 + 0^2)

= 9mb^2 + 12mb^2 + 2mb^2

= 23mb^2

I_xy = I_xz = I_yx = I_yz = I_zx = I_zy = 0

I_yy = 3m * (b^2 + 0^2 + b^2) + 4m * (b^2 + 0^2 + (-b)^2) + 2m * ((-b)^2 + b^2 + 0^2)

= 6mb^2 + 12mb^2 + 2mb^2

= 20mb^2

I_zz = 3m * (b^2 + b^2 + 0^2) + 4m * (b^2 + (-b)^2 + 0^2) + 2m * (0^2 + b^2 + 0^2)

= 6mb^2 + 12mb^2 + 2mb^2

= 20mb^2

Now, let's write down the inertia tensor:

I = | I_xx 0 0 |

| 0 I_yy 0 |

| 0 0 I_zz |

Diagonalizing the inertia tensor, we can obtain the principal axes and principal moments of inertia.

The diagonalized form of the inertia tensor is obtained by finding the eigenvalues and eigenvectors of the inertia tensor. Since the inertia tensor is already diagonal, the principal axes are the coordinate axes (x, y, and z), and the principal moments of inertia are the diagonal elements of the inertia tensor:

I_xx = 23mb^2

I_yy = 20mb^2

I_zz = 20mb^2

Therefore, the principal axes are the coordinate axes (x, y, z), and the principal moments of inertia are 23mb^2, 20mb^2, and 20mb^2 for the x, y, and z axes, respectively.

a. The Sackur-Tetrode equation has the entropy to be  S = NkB [2 + 3[2 - ln(pX³h)]

b.  3S = NkB ln(V / Nλ³  shows the entropy of a gas with distinguishable particles

c.  The quantity 3S = NkB ln(V / Nλ³) is not an extensive quantity because it does not scale linearly with the size of the system.

a)

Entropy in the Sackur-Tetrode equation is denoted by S = NkB [2 + 3[2 - ln(pX3h)],

N = particle count,

kB = Boltzmann constant,

p =  gas's number density,

X = thermal wavelength,

h = Planck's factor.

When we consider two systems, each with a different number of particles and volume, the entropy of the combined system is equal to the sum of the entropies of the individual systems.

b) The entropy is given by 3S = NkB ln(V / Nλ³),

where V =  volume,

N=  total number of particles,

λ=  thermal wavelength.

The Helmholtz free energy (F) is defined as

F_ = U - TS.

IF we  differentiate the Helmholtz free energy with respect to temperature (T), we can obtain the entropy expression 3S = NkB ln(V / Nλ³).

c)  

Because it does not increase linearly with system size, the amount 3S = NkB ln(V / N3) is not a large quantity. In a large quantity, doubling the system's size would also double the quantity's value.

In this our scenario, doubling the system size would not result in a doubling of the entropy. As a result, it is not regarded as a large number.

The Horizontal distance to floor  is 0.7246 m or 72.46 cm

The reflection of the nearest part of the floor will be seen at the bottom part of the mirror.

Vertical Distance of eyes - Vertical distance of bottom edge of mirror

= 1.62 - 0.4

= 1.22 m

Note that:

Tan(theta) = Perpendicular/Base

Tan(theta) = 1.22 / 2.21

Thus, the car travels 500 m after starting. Hence, the correct option is (c) 500 m.

Given that a car starting from rest accelerates at a constant 2.0 m/s² for 10 s, it then travels with constant speed it has achieved for another 10 s and finally slows to a stop with constant acceleration of magnitude 2.0 m/s². We need to determine how far it travels after starting.

To determine the distance traveled, we have to calculate the total distance traveled in each of the three phases and then add them together. Let's calculate each phase separately:

Phase 1: From rest, the car is accelerating at 2.0 m/s² for 10 seconds. We know that, Acceleration, a = 2.0 m/s²Time taken, t = 10 s Initial velocity, u = 0 m/s Distance, S = ?The formula for the distance covered during acceleration is given by, S = ut + 1/2at²S = 0 + 1/2 × 2.0 m/s² × (10 s)²S = 100 m So, the distance covered in Phase 1 is 100 m.

Phase 2: The car travels at constant speed for 10 seconds. The car continues to move with a constant speed for 10 seconds. Distance covered during the constant speed phase = Speed × Time As there is no acceleration during this phase, speed = acceleration × time + initial velocity = 2.0 m/s² × 10 s + 0 = 20 m/s Therefore, the distance covered in Phase 2 is 20 m/s × 10 s = 200 m.

Phase 3: Finally, the car comes to a stop with a deceleration of 2.0 m/s² for some time, say t seconds.

Distance covered during the deceleration phase, Acceleration, a = −2.0 m/s², Time taken, t = ?Initial velocity, u = 20 m/s Distance, S = ?

The formula for the distance covered during deceleration is given by:

S = ut + 1/2at²S = 20 m/s × t + 1/2 × (−2.0 m/s²) × t²S = 20t − t² m

Now, using the third equation of motion, we have,

v² = u² + 2

as where v = 0 m/s (final velocity), u = 20 m/s (initial velocity), ma = −2.0 m/s² (deceleration)

S = ?

Substituting the values in the above equation, we get:

0 = (20 m/s)² + 2 × (−2.0 m/s²) × S

Solving for S,S = 200 m

Therefore, the distance covered in Phase 3 is 200 m.

Finally, the total distance covered by the car can be obtained by adding the distances covered in the three phases.

Distance covered = 100 m + 200 m + 200 m = 500 m.

Answer: v = 0.6 m/s

Explanation: Momentum Conservation Principle states that for a collision between two objects in an isolated system, the total momentum of the objects before the collision is equal to the total momentum of the objects after the collision.

Momentum is calculated as Q = m.v

For the piñata problem:

\(Q_{i}=Q_{f}\)

\(m_{p}v_{p}_{i}+m_{s}v_{s}_{i}=m_{p}v_{p}_{f}+m_{s}v_{s}_{f}\)

Before the collision, the piñata is not moving, so \(v_{p}_{i}=0\).

After the collision, the stick stops, so \(v_{s}_{f}=0\).

Rearraging, we have:

\(m_{s}v_{s}_{i}=m_{p}v_{p}_{f}\)

\(v_{p}_{f}=\frac{m_{s}v_{s}_{i}}{m_{p}}\)

Substituting:

\(v_{p}_{f}=\frac{(0.54)(4.8)}{(4.4)}\)

\(v_{p}_{f}=\) 0.6

Immediately after being cracked by the stick, the piñata has a swing speed of 0.6 m/s.

Answer:

it needs to be shaken but make sure you have enough room to shake it safely

Explanation:

To properly operate the laboratory thermometer  it needs to be shaken but make sure you have enough room to shake it safely. This done because there is a small bend in the mercury channel of a clinical thermometer that uses mercury. You must shake the thermometer to get the mercury from a previous reading from the thermometer back into the bulb for taking new reading. The bend prevents flow back into the tube so that one can comfortably take reading.

The speed of the first car is 52 mph.

The speed of the second car is 40 mph.

Let's use "x" mph to represent the second car's speed. We can express the first car's speed as "x + 12" mph because it is 12 mph faster. According to our knowledge, the first car travelled 234 miles, while the second car covered 180 miles.

The relationship between speed and distance travelled is inversely proportional. As a result, the proportion of distances covered by the two vehicles will match the proportion of their speeds:

234 / 180 = (x + 12) / x

To solve this equation, we can cross-multiply:

234x = 180(x + 12)

Expanding the equation:

234x = 180x + 2160

Rearranging terms:

234x - 180x = 2160

54x = 2160

Dividing both sides by 54:

x = 40

Therefore, the speed of the second car is 40 mph.

To find the speed of the first car, we can substitute the value of x back into the expression "x + 12":

x + 12 = 40 + 12 = 52

Hence, the speed of the first car is 52 mph.

Answer:

Explanation:

Assuming the potential energy is due to the gravitational potential energy, we can use the conservation of energy to find the kinetic energy:

Total energy = Potential energy + Kinetic energy

Kinetic energy = Total energy - Potential energy

Kinetic energy = 300 J - 40 J = 260 J

However, we need to know the mass of the object to convert the kinetic energy to velocity. We can use the potential energy to find the mass:

Potential energy = mgh

40 J = m(9.81 m/s^2)(300 m)

m = 0.137 kg

Now we can use the kinetic energy to find the velocity:

Kinetic energy = (1/2)mv^2

260 J = (1/2)(0.137 kg)v^2

v^2 = (2*260 J) / 0.137 kg

v = 43.3 m/s (rounded to one decimal place)

Therefore, the kinetic energy is 260 J and the velocity of the object when it reaches the ground is 43.3 m/s.
