The density of water is 1.00 g/cm3. What is its density in kg/m3?
Answers
Answer:
The metric system was originally devised so that water would have a density of 1 g/cm3, equivalent to 103 kg/m3.
Answer:
\(10^{3}\; \rm kg \cdot m^{-3}\).
Explanation:
Convert the unit in two steps:
Convert \(\rm g\) to \(\rm kg\) given that \(10^{3}\; \rm g = 1\; \rm kg\).Convert \(\rm cm^{3}\) to \(\rm m^{3}\) given that \(10^{6}\; \rm cm^{3} = (10^{2})^{3}\; \rm cm^{3} = 1\; \rm m^{3}\).Start by converting \(\rm g\) to \(\rm kg\). Since \(10^{3}\; \rm g = 1\; \rm kg\), multiplying the original value by the ratio \(\displaystyle \frac{1\; \rm kg}{10^{3}\; \rm g}\) would not change of the value expression:
\(\begin{aligned}& 1.00\; \rm \frac{g}{cm^{3}} \\ =\; & 1.00\; \frac{\rm g}{\rm cm^{3}} \times \frac{1\; \rm kg}{10^{3}\; \rm g} \\ =\; & 1.00\times 10^{-3}\; \frac{\rm kg}{\rm cm^{3}}\end{aligned}\).
Convert \(\rm cm^{3}\) to \(\rm m^{3}\). Notice that the original unit \(\rm cm^{3}\!\!\) is in the denominator. Thus, choose a ratio where \(\rm cm^{3}\!\) is in the numerator: \(\displaystyle \frac{10^{6}\; \rm cm^{3}}{1\; \rm m^{3}}\).
\(\begin{aligned}& 1.00\times 10^{-3}\; \frac{\rm kg}{\rm cm^{3}} \\=\; & 1.00\times 10^{-3}\; \frac{\rm kg}{\rm cm^{3}} \times \frac{10^{6}\; \rm cm^{3}}{1\; \rm m^{3}} \\ =\; & 1.00 \times 10^{3}\; \frac{\rm kg}{\rm m^{3}}\end{aligned}\).
In other words, \(1.00\; \rm g \cdot cm^{-3} = 1.00 \; \rm kg \cdot m^{-3}\).

Answers
In this experiment, marbles were rolled down a ramp to determine the relationship between potential and kinetic energy and how it affects the distance a box will slide.
How did the potential energy differ?The potential energy of the marbles differed based on their starting location, with higher locations possessing more potential energy. As the marbles rolled down the ramp, their potential energy decreased while their kinetic energy increased.
When the marble hit the box, it transferred its kinetic energy to the box, causing it to slide backward. The results showed that the higher the marble's potential energy, the further the box slid.
Additionally, the larger the mass of the marble, the greater its kinetic energy and the further the box slid. Overall, the hypotheses for each experiment were confirmed by the data collected.

a flatbed truck is carrying a crate along a level road. the coefficient of static friction between the load and the bed is 0.40. the truck accelerates forward and the crate stays in its place on the truck bed. in what direction is the force that the bed exerts on the crate?
Answers
The direction is the force that the bed exerts on the crate Forward.
Friction between the track and the crate holds the crate in place and allows the crate to move with the vehicle. As a result, the crate's frictional force is directed north, in the same direction as the truck's velocity. As mentioned earlier, both the horizontal and vertical forces have a magnitude of 0 so there is no net force on the box. Therefore, the force on the box has no direction.
The net force always has the same direction as the acceleration. For an object in a circular motion with constant velocity, the net force is directed toward the center of the circle around which the object is moving. The frictional force acts on a moving object, and its direction is opposite to the direction of movement. As we walk, our feet are pushed backward so friction works in the opposite direction to counteract the push.

In an RLC series circuit, the rms potential difference provided by the source is V = 210 V, and the frequency is f = 250 Hz. Given that L = 0.35 H, C = 70 uF, and VR = 45 V, find: , = 3 a) I (rms); I 1.962331945 = A b) R; R = 44.65985162 12 c) VL (rms); Vi 176.3328743 V d) Vc (rms). VCE = 28.78760123 V
Answers
Answer:
The rms voltage across the capacitor is approximately 224.926 V.
a) To find the rms current (I) in the RLC series circuit, we can use the formula:
I = V / Z
Where V is the rms potential difference provided by the source, and Z is the impedance of the circuit.
The impedance of an RLC series circuit is given by:
Z = √(R^2 + (Xl - Xc)^2)
Where R is the resistance, Xl is the inductive reactance, and Xc is the capacitive reactance.
V = 210 V
f = 250 Hz
L = 0.35 H
C = 70 uF
VR = 45 V
First, let's calculate the reactances:
Xl = 2πfL
Xc = 1 / (2πfC)
Substituting the values:
Xl = 2π * 250 * 0.35
Xc = 1 / (2π * 250 * 70e-6)
Calculating:
Xl ≈ 549.78 Ω
Xc ≈ 114.591 Ω
Next, we can calculate the impedance:
Z = √(R^2 + (Xl - Xc)^2)
Substituting the given VR value, we have:
VR = I * R
Rearranging the equation to solve for R:
R = VR / I
Substituting the given values:
45 = I * R
Solving for R:
R = 45 / I
Substituting the values of Xl and Xc into the impedance equation:
Z = √(R^2 + (549.78 - 114.591)^2)
Substituting the value of Z into the formula for rms current:
I = V / Z
Calculating:
I ≈ 1.962331945 A
Therefore, the rms current in the RLC series circuit is approximately 1.962 A.
b) The resistance (R) in the circuit can be found using the equation:
R = VR / I
Substituting the given values:
R = 45 / 1.962331945
Calculating:
R ≈ 22.943 Ω
Therefore, the resistance in the RLC series circuit is approximately 22.943 Ω.
c) The rms voltage across the inductor (VL) can be calculated using the formula:
VL = I * Xl
Substituting the values:
VL = 1.962331945 * 549.78
Calculating:
VL ≈ 1,076.644 V
Therefore, the rms voltage across the inductor is approximately 1,076.644 V.
d) The rms voltage across the capacitor (Vc) can be calculated using the formula:
Vc = I * Xc
Substituting the values:
Vc = 1.962331945 * 114.591
Calculating:
Vc ≈ 224.926 V
Therefore, the rms voltage across the capacitor is approximately 224.926 V.

Answers
Answer:
f₁ = 1 Hz
f₂ = 0.75 Hz
Explanation:
The given time lapse between the two frequencies, t = 2 s
The frequency of a wave is the number of complete one cycles of the wave that pass through a given point in a given unit of time
The unit of frequency, 'f', is the Hertz, Hz
Therefore, frequency = Number of cycles/(Time)
The frequency of a wave, f = n/t
Where;
n = The number of completed cycles in a given time
The frequency of the first wave 1, f₁
The number of complete cycles by wave 1 in the 2 seconds, n = 2 cycles
The time, t = 2 seconds
The frequency of wave 1, f₁ = 2 cycles/(2 seconds) = 1 cycle/second = 1 Hz
The frequency of the second wave, wave 2, f₂
The number of complete cycles by wave 2 in the 2 seconds, n = 1 and half cycles = 1.5 cycles
The time, t = 2 seconds
The frequency of wave 2, f₂ = 1.5 cycles/(2 seconds) = 0.75 cycle/second = 0.75 Hz

Show that F2 = qP act as a generating function for

Answers
F2 = qP acts as a generating function for the identity transformation, where q = Q and p = P.
In mathematics, a generating function is a powerful tool used to represent a sequence of numbers or a transformation in a compact and convenient form. The generating function F2 = qP represents a transformation where q and p are variables.
To show that F2 generates the identity transformation, we need to demonstrate that when q = Q and p = P, the generating function F2 simplifies to the identity function.
When q = Q and p = P, we can substitute these values into the equation F2 = qP. This gives us F2 = QP. Since Q and P are constants, the product QP is also a constant value.
In mathematics, the identity transformation is defined as a transformation that leaves each element unchanged. Therefore, for F2 to represent the identity transformation, it should evaluate to a constant value.
By setting q = Q and p = P in the generating function F2 = qP, we obtain F2 = QP, which is a constant value. This indicates that the generating function F2 yields the identity transformation, where q = Q and p = P.
In conclusion, by substituting q = Q and p = P into the generating function F2 = qP, we obtain a constant value, which represents the identity transformation. Therefore, F2 = qP acts as a generating function for the identity transformation when q = Q and p = P.

8. The force constant of a spring is 150. N/m. (a) How much force is required to stretch the spring 0.25 m? (b) How much work is done on the spring in that case?
Answers
Answer:
a) 37.5N
b) 9.375Joules
Explanation:
a) According to Hooke's law
F = ke
k is the spring constant
e is the extension;
F = 150 * 0.25
F = 37.5N
b) Work done on the spring = 1/2ke^2
Work done on the spring = 1/2 * 150 * 0.25^2
Work done on the spring = 75 * 0.0625
Work done on the spring = 9.375Joules
(a) The force required to stretch the spring is of 37.5 N.
(b) The work done on the spring is of 4.6775 J.
Given data:
The force constant of a spring is, k = 150 N/m.
The stretching distance of spring is, x = 0.25 m.
(a)
When some force is experienced on the spring, then due to this force then it will displace. Then, the expression for the force applied on the spring is given as,
\(F = k \times x\)
Solve by substituting the values as,
\(F = 150 \times 0.25\\\\F = 37.5 \;\rm N\)
Thus, we can conclude that the force required to stretch the spring is of 37.5 N.
(b)
And the expression for the work done on the spring is given as,
\(W = \dfrac{1}{2}kx^{2}\)
Solving as,
\(W = \dfrac{1}{2} \times 150 \times 0.25^{2}\\\\W = 4.6875 \;\rm J\)
Thus, we can conclude that the work done on the spring is of 4.6775 J.

d. Describe the relative speeds of sound in the different states of matter.
Answers
Answer:
A. The property of sound waves that is related to pitch is its frequency. Higher frequency sound waves create higher-pitched sounds, while lower frequency sound waves create lower-pitched sounds.
B. The property of sound waves that is related to volume is its amplitude. Larger amplitude sound waves create louder sounds, while smaller amplitude sound waves create softer sounds.
C. The Doppler effect is the change in frequency or wavelength of a wave in relation to an observer who is moving relative to the wave source. It is commonly observed in sound waves, such as the change in pitch of a siren as an ambulance passes by. The Doppler effect occurs because the relative motion between the wave source and the observer causes a change in the effective distance that the wave travels, resulting in a change in its frequency.
D. The speed of sound varies depending on the state of matter it is traveling through. In general, sound travels fastest through solids, slower through liquids, and slowest through gases. In air at room temperature and pressure, sound travels at a speed of approximately 343 meters per second (1,125 feet per second), while in water, sound travels at a speed of about 1,480 meters per second (4,850 feet per second). In solids such as steel, sound can travel at speeds up to 5,960 meters per second (19,550 feet per second)

Answers
B. Increasing the area of their contact would increase heat transfer between two objects.
Heat transfer occurs due to a temperature difference between two objects in contact with each other.
The rate of heat transfer is proportional to the temperature difference, the thermal conductivity of the materials, and the surface area in contact between the objects.
Therefore, increasing the area of contact between two objects will increase the rate of heat transfer between them.
Establishing thermal equilibrium, using objects with similar specific heats, and reducing the time of contact will not necessarily increase heat transfer between the two objects.
