Answer:
300km
Explanation:
To find the total distance traveled within the given time frame, we need to known that distance is the product speed and time;
Distance = Speed x time
For the first lap:
Distance = 100km/hr x 3hr = 300km
For the second lap;
Distance = 150km/hr x 2 = 300km
Distance = 300km + 300km
So;
Distance = 300km

A una temperatura de 329°K una placa de aluminio tiene un área de 15 m2, si su temperatura disminuye hasta 288°K; ¿Cuál es el valor de su área final?
Answer:
El área final de la placa de aluminio es 14.971 metros cuadrados.
Explanation:
Para pequeñas deformaciones, la expresión para la dilatación de área es la siguiente:
[tex]A_{f} = A_{o} \cdot [1+2\cdot \alpha \cdot (T_{f}-T_{o})][/tex] (1)
Donde:
[tex]A_{o}[/tex], [tex]A_{f}[/tex] - Áreas inicial y final de la placa, medidas en metros cuadrados.
[tex]\alpha[/tex] - Coeficiente de expansión lineal, medido en [tex]\frac{1}{K}[/tex].
[tex]T_{o}[/tex], [tex]T_{f}[/tex] - Temperaturas inicial y final de la placa, medidas en Kelvin.
Si sabemos que [tex]A_{o} = 15\,m^{2}[/tex], [tex]\alpha = 23\times 10^{-6}\,\frac{1}{K}[/tex], [tex]T_{o} = 329\,K[/tex] y [tex]T_{f} = 288\,K[/tex], entonces el área final de la placa es:
[tex]A_{f} = (15\,m^{2})\cdot \left[1+2\cdot \left(23\times 10^{-6}\,\frac{1}{K} \right)\cdot (288\,K-329\,K)\right][/tex]
[tex]A_{f} = 14.971\,m^{2}[/tex]
El área final de la placa de aluminio es 14.971 metros cuadrados.

A horse pulls a carriage by applying 450 N of force. Find the traveled distance if the horse did 89 kJ of work.
Answer:
distance = 197.8 m
Explanation:
Use the formula for work as the force times the distance the force was acting on the object.
W = F * d
89000 J = 450 N * d
d = 89000/450 m
d = 197.8 m

The whale shark the largest of fish and can have the mass of three adult elephants. Suppose that a crane is whale shark into a tank for delivery to an aquariumThe crane must exert an unbalanced force of 2.5 * 10 ^ 4 to lift the shark from rest. If the shark's acceleration equals 1.25 m/s ^ 2 , what is the shark's mass?
Answer:
Mass, m = 20000 kg
Explanation:
The force acting on the shark, [tex]F=2.5\times 10^4\ N[/tex]
Acceleration of the shark, a = 1.25 m/s²
We need to find the mass of the Shark. The force acting on an object is given by :
F = ma
m is the shark's mass
So,
[tex]m=\dfrac{F}{a}\\\\m=\dfrac{2.5\times 10^4}{1.25}\\\\m=20000\ kg[/tex]
So, the mass of the Shark is 20000 kg.

Which is NOT considered as a property of electromagnetic waves: 5
- Travels at speed of 3 x 10^8 m/s
- Transverse wave
- Transfer energy /information
- Require a medium to propogate
Answer:
require a medium to propagate
Explanation:
this is because electromagnetic waves can travel through vacuum at the speed of 3.0 x 10^8 m/s
because they don't need particles to transfer energy

prove that total mechanical energy is always constant
Explanation:
We know that the overall mechanical energy of a device stabilizes in the absence of any external force. We know that that the total of potential and kinetic of the freely velocity vector remains same. ,So mechanical energy of a body, underneath gravitation, remains constant.

can you please explain hooks law?
Explanation:
Hooke's law is a law of physics that states that the force needed to extend or compress a spring by some distance scales linearly with respect to that distance—that is, Fₛ = kx, where k is a constant factor characteristic of the spring, and x is small compared to the total possible deformation of the spring.
what must be true the number of chromosomes in each sex cell
Answer:
In humans, each cell normally contains 23 pairs of chromosomes, for a total of 46.
Three forces are acting on an object as shown in the diagram. The object is not moving. Two forces are to newtons and 10 N. Third force is:
The object is not moving, so the net force acting on it is zero.
The two given forces act in the same direction with a total magnitude of 2 N + 10 N = 12 N.
The third force acts counter to these with some magnitude F to give a net force of 0, so that by Newton's second law
F = 12 N

Why do our eyes see the color red when we look at a tomato?
A. Tomatoes emit red light.
B.Tomatoes reflect red light and absorb green and blue light.
C. Tomatoes absorb red light and reflect green and blue light.
D. Tomatoes reflect all colors of light, but our eyes only absorb red light,
Answer:
B. Tomatos reflect red light
Explanation:
The only reason colors exist is because the objects with color reflect all other light except for what they are portrayed as. White reflects all colors, and black absorbs all colors.
If you have any questions feel free to ask :)
Answer:
Explanation: the pigment atoms in the skin absorb photons of all energies except those that correspond to red wavelengths of light, which they reflect back to your eye.

20. The triple-point of water occurs at 273.16 K (0.01 °C) and a vapor pressure of 0.0060373 atm). At this point water can be ______________. solid B. Liquid C. Gas D. All of the above E. None of the above
Answer:
E i think.
Explanation:
The triple-point of water occurs at 273.16 K (0.01 °C) and a vapor pressure of 0.0060373 atm. At this point water can be solid, liquid and gas. So, option (D) is correct.
What is phase diagram?phase diagram: a graph that displays the limiting conditions for a substance's solid, liquid, and gaseous phases under changes in pressure, temperature, or another combination of variables, such as solubility and temperature.
The curves in the figure were derived from measurements taken at various pressures and temperatures, and they represent a typical phase diagram for a one-component system (i.e., one made up of a single pure chemical).
What is triple-point?The combination of temperature and pressure at which a substance can exist in all three of its states—gas, liquid, and solid—is known as the triple point.
The Kelvin(K), the International System of Units' (SI) fundamental unit of thermodynamic temperature, is defined using the triple point of water. The triple-point of water occurs at 273.16 K (0.01 °C) and a vapor pressure of 0.0060373 atm.
