A spring is stretched 0.15 m and the force was 1500 N. What is the spring constant?
The spring constant for a spring is stretched 0.15 m and the force was 1500 N is 10000.
What is spring constant?The spring constant, k, is a measure of the spring's stiffness. It varies depending on the spring and material. The greater the spring constant, the stiffer the spring and more difficult to stretch.
The letter k symbolizes the "spring constant," which is a number that tells us how "stiff" a spring is.
If k is large, it means that more force is required to stretch it a certain length than would be required to stretch a less stiff spring the same length.
We know that,
F = k(x)
Where k is the spring constant.
Here, it is given that:
F = 1500N
x = 0.15m
So,
1500 = k (0.15)
k (0.15) = 1500
k = 1500/0.15
k = 150000/15
k = 10000
Thus, the value of spring constant is 10000.

Geothermal energy is an alternative energy source, although it is not resourceful enough to replace more than a minor amount of the Earth’s energy needs. Why is this?
Answer: However, it is not resourceful enough to replace more than a minor amount of the Earth's energy needs. Drilling through the Earth to reach areas hot enough to create steam is possible, but very expensive and difficult. .

Resolver: Una bala de 0.8 de masa se mueve horizontalmente con una velocidad de 30 m/s y se introduce en un bloque de 4kg, inicialmente en reposo. ¿Cuál es la velocidad de la bala y el bloque después del impacto?
Answer:
La velocidad del sistema bala-bloque es 5 metros por segundo.
Explanation:
El enunciado tiene una omisión gramatical. La forma correcta es la siguiente:
Una bala de 0.8 kilogramos de masa se mueve horizontalmente con una velocidad de 30 metros por segundo y se introduce en un bloque de 4 kilogramos, inicialmente en reposo. ¿Cuál es la velocidad de la bala y el bloque después del impacto?
Esta situación es un caso clásico de colisión enteramente inelástica, en donde el sistema bala-bloque no tiene influencia de fuerzas externas, entonces la situación queda descrita por la siguiente ecuación:
[tex]m_{b}\cdot v_{b,o} = (m_{b}+m_{B})\cdot v[/tex] (1)
Donde:
[tex]m_{b}[/tex] - Masa de la bala, en kilogramos.
[tex]v_{b,o}[/tex] - Velocidad inicial de la bala, en metros por segundo.
[tex]m_{B}[/tex] - Masa del bloque, en kilogramos.
[tex]v[/tex] - Velocidad del sistema bala-bloque, en metros por segundo.
Si sabemos que [tex]v_{b,o} = 30\,\frac{m}{s}[/tex], [tex]m_{b} = 0.8\,kg[/tex] y [tex]m_{B} = 4\,kg[/tex], entonces la velocidad del sistema masa-bloque es:
[tex]v = \frac{m_{b}}{m_{b}+m_{B}}\cdot v_{b,o}[/tex]
[tex]v = 5\,\frac{m}{s}[/tex]
La velocidad del sistema bala-bloque es 5 metros por segundo.
In regions of the cardiovascular system where there is steady laminar blood flow, the shear stress on cells lining the walls of the blood vessels is about 20 N / M2. If the shear strain is about 0.008, estimate the shear modulus for the affected cells.
Answer:
Shear Modulus = 2500 Pa = 2.5 KPa
Explanation:
The shear modulus is defined as the ratio between the shear stress and the shear strain. Hence, the shear modulus, in this case, can be calculated by the use of the following formula:
[tex]Shear\ Modulus = \frac{Shear\ Stress}{Shear\ Strain}\\[/tex]
we have,
shear stress = 20 N/m²
shear strain = 0.008
Therefore,
[tex]Shear\ Modulus = \frac{20\ N/m^2}{0.008}\\\\[/tex]
Shear Modulus = 2500 Pa = 2.5 KPa

10. A jogger runs along a road for a distance of 2700 m. If it takes her 900 seconds
to run that distance, what is her speed?
Answer:
Speed = 3 m/s
Explanation:
Given the following data;
Distance = 2700m
Time = 900 s
To find the speed;
Speed can be defined as distance covered per unit time. Speed is a scalar quantity and as such it has magnitude but no direction.
Mathematically, speed is given by the formula;
[tex]Speed = \frac{distance}{time}[/tex]
Substituting into the equation, we have;
[tex]Speed = \frac{2700}{900}[/tex]
Speed = 3 m/s
An effect analogous to two-slit interference can occur with sound waves, instead of light. In an open field, two speakers placed 1.19 m apart are powered by the same function generator producing sine waves at 1,163 Hz frequency. Assume that the speed of sound is 340 m/s. A student walks along a line 12.5 m away and parallel to the line from one speaker to the other speakers. She hears an alternating pattern of loud and quiet, due to constructive and destructive interference. What is the distance between the central maximum and the first maximum (loud) position along this line in m
Answer:
3.04 m
Explanation:
The interference by diffraction of waves is noticeable only when the dimension of the opening through which the wave is passing through is comparable to the wavelength of the passing wave.
It is given that :
Distance between two speakers, d = 1.19 m
Speed of sound, v = 340 m/s
The frequency is f = 1163 Hz
Distance the student walk along the line of the speaker, D = 12.5 m
We know the wavelength of the sound produced by the speakers is given by :
[tex]$\lambda=\frac{v}{f}$[/tex]
[tex]$=\frac{340}{1163}$[/tex]
= 0.29 m
Now the distance between the central maximum and the first maximum position is given by :
[tex]$y=\frac{\lambda D}{d}$[/tex]
[tex]$=\frac{0.29 \times 12.5}{1.19}$[/tex]
= 3.04 m
The mass of an object is 42.8 kg. Calculate the weight on the Earth.
Answer:
428 Newtons
Explanation:
Weight = Mass * Acceleration (due to gravity)
42.8 × 10 =428 N
Explanation:
[tex]weight = mass \times gravitational \: field \: strength[/tex]
gravitational field strength on earth is 9.81m/s²
so weight = 42.8 * 9.81

A 25 N force stretches a spring 0.280 m. What was the spring constant?
Answer:
the spring constant is -89.2857 n/m
Explanation:
The computation of the spring constant is shown below:
As we know that
Force in newtons = Spring constant × amount of extension
F = -k × x
where
F = 25 N
And, x = 0.280m
So, the spring constant would 2
= 25N ÷ 0.280 m
= -89.2857 n/m
Hence the spring constant is -89.2857 n/m

2. A₂ = 1.2 A
Explanation:
1. Determination of the voltage measured at R₃.
Voltage at R₁ (V₁) = 1 V
Voltage at R₂ (V₂) = 6 V
Total voltage (Vₜ) = 12 V
Voltage at R₃ (V₃) =.?
Vₜ = V₁ + V₂ + V₃
12 = 1 + 6 + V₃
12 = 7 + V₃
Collect like terms
12 – 7 = V₃
V₃ = 5 V
Thus, the voltage measured at R₃ is 5 V
2. Determination of A₂.
From the circuit diagram, we can see that the resistors are in series arrangement. This means that the same current will pass through each resistor.
Thus,
A₂ = A₁ = 1.2 A

Describe what happens to a moving object if NO forces are acting on it
Answer:
An object with no net forces acting on it which is initially at rest will remain at rest. If it is moving, it will continue to move in a straight line with constant velocity. Forces are "pushes" or "pulls" on the object, and forces, like velocity and acceleration are vector quantities.

Answer:
Stir/agitate and heat the tea
Answer:
Stir the tea, Heat the tea, and Grind the sugar
Explanation:
Heating and stirring both increase the energy of the tea molecules, which increases interactions with the sugar. Grinding sugar allows more sugar molecules to be exposed to the solvent particles that dissolve them.
