Answer:
Both nuclear fission and nuclear fusion produce energy from
matter
:D
Both nuclear fission and nuclear fusion produce energy from matter is the statement correctly comparing nuclear fission with nuclear fusion.
What is nuclear fusion?The process by which two or more tiny nuclei unite to generate a bigger nucleus is known as a nuclear fusion reaction.
The more energy it takes to liberate an electron from a smaller atom. This is referred to as binding energy.
As a result, when two little nuclei fuse together, there is more binding energy than when two big nuclei fuse together.
For example, the fusion of two hydrogen atoms produces more energy than the fusion of one helium atom, and surplus energy is expelled into space upon binding.
Both nuclear fission and nuclear fusion produce energy from matter is the statement correctly comparing nuclear fission with nuclear fusion.
Hence option D is correct.

The horizontal distance between two nodes is 1.5 meters what is the wavelength of then standing wave
Answer:
[tex]\lambda=3\ m[/tex]
Explanation:
Given that,
The horizontal distance between the two nodes is 1.5 meters.
We need to find the wavelength of the standing wave.
If we know the distance between nodes and antinodes, then the equation is :
[tex]\dfrac{\lambda}{2}=D[/tex]
Where
[tex]\lambda[/tex] is the wavelength
So,
[tex]\lambda=2D\\\\=2\times 1.5\\\\=3\ m[/tex]
So, the wavelength of the standing wave is equal to 3 m.
How many degrees equal π in radians? How many revolutions (turns) equal π radians?
Answer:
It follows that the magnitude in radians of one complete revolution (360 degrees) is the length of the entire circumference divided by the radius, or 2πr / r, or 2π. Thus 2π radians is equal to 360 degrees, meaning that one radian is equal to 180/π ≈ 57.295779513082320876 degrees.

Answer:
Average acceleration of the car is 1.167 m/s^2
Explanation:
The speed of car with which it is travelling is 12 m/s
As the driver accelerates the car, the speed reaches 26 m/s
The change in speed in 12 seconds is
26 -12 = 14 m/s
Average acceleration is change in speed divided by time

A vertical piston-cylinder device initially contains 0.1 m^3 of air at 400 K and 100 kPa. At this initial condition, the piston is resting on a stop. The piston-cylinder device is connected to a supply line with air at 400 K and a pressure of 500 kPa. The valve between the supply line and the piston-cylinder device is opened and is left open until the pressure in the piston-cylinder device reaches 500 kPa. The piston is observed to start moving when the pressure in the cylinder is 200 kPa and the piston continues to rise until it reaches a second stop. At the second stop, the piston-cylinder volume is 0.2 m^3 . The final temperature and pressure in the piston-cylinder device are 440 K and 500 kPa, respectively. Determine the heat transfer to or from the piston-cylinder device for the filling process Determine heat transfer (kJ) during the entire process.

30 kg sits on a table the acceleration due to gravity is 10 m/s^2 what force does the table exert on the television.
0.3N
3N
300N
600N
Answer:
300N
Explanation:
F=m×a
F=30kg×10m/s^2
F=300N
If 30 kilograms sit on a table the acceleration due to gravity is 10 meters/second², then the force exerted by the table on the television would be 300 Newtons,
Therefore the correct answer is option C.
What is acceleration?The rate of change of the velocity with respect to time is known as the acceleration of the object.
As given in the problem If 30 kilograms sit on a table the acceleration due to gravity is 10 meters/second²,
the force exerted = mass × acceleration due to gravity
= 30 kilograms × 10 meters/second²
= 300 Newtons
Thus, the force exerted by the table on the television would be 300 Newtons,

Una botella vacía tiene una masa de 24.25g y de 86.55g completamente llena de agua, se vacia el agua y se llena nuevamente con 123.95g de solvente tetracloruro de carbono, ¿cual es la densidad del solvente?
Answer:
La densidad del tetracloruro de carbono es 1.990 gramos por centímetro cúbico.
Explanation:
La masa de agua contenida dentro de la botella es igual a la diferencia entre la masa pesada totalmente llena y la masa pesada totalmente vacía, es decir:
[tex]m_{w} = 86.55\,g-24.25\,g[/tex]
[tex]m_{w} = 62.3\,g[/tex]
Ahora, de acuerdo con la definición de densidad, la masa es directamente proporcional a la densidad, entonces, podemos calcular la densidad del solvente mediante la siguiente relación:
[tex]\frac{m_{x}}{m_{w}} = \frac{\rho_{x}}{\rho_{w}}[/tex] (1)
Donde:
[tex]m_{x}[/tex] - Masa del tetracloruro de carbono, en gramos.
[tex]m_{w}[/tex] - Masa del agua, en gramos.
[tex]\rho_{x}[/tex] - Densidad del tetracloruro de carbono, en gramos por centímetro cúbico.
[tex]\rho_{w}[/tex] - Densidad del agua, en gramos por centímetro cúbico.
Si sabemos que [tex]m_{x} = 123.95\,g[/tex], [tex]m_{w} = 62.3\,g[/tex] y [tex]\rho_{w} = 1\,\frac{g}{cm^{3}}[/tex], entonces la densidad del tetracloruro de carbono es:
[tex]\rho_{x} = \left(\frac{m_{x}}{m_{w}} \right)\cdot \rho_{w}[/tex]
[tex]\rho_{x} = 1.990\,\frac{g}{cm^{3}}[/tex]
La densidad del tetracloruro de carbono es 1.990 gramos por centímetro cúbico.
4. Un móvil viaja en línea recta con una velocidad media de 1200 cm/s durante 9 s, y luego con velocidad media de 480 cm/s durante 7 s, siendo ambas velocidades del mismo sentido: a) ¿cuál es el desplazamiento total en el viaje de 16 s? B) ¿cuál es la velocidad media del viaje completo?
Answer:
A) El desplazamiento total del viaje es 14160 centímetros.
B) La velocidad media del viaje completo es 885 centímetros por segundo.
Explanation:
A) El desplazamiento es el producto de la velocidad media por el tiempo. El desplazamiento total es la suma de desplazamientos asociados a cada velocidad media, entonces:
[tex]x = \left(1200\,\frac{cm}{s}\right)\cdot (9\,s)+ \left(480\,\frac{cm}{s} \right)\cdot (7\,s)[/tex]
[tex]x = 14160\,cm[/tex]
El desplazamiento total del viaje es 14160 centímetros.
B) La velocidad media del viaje es el desplazamiento total dividido por el tiempo total, es decir:
[tex]\bar v = \frac{14160\,cm }{16\,s}[/tex]
[tex]\bar v = 885\,\frac{cm}{s}[/tex]
La velocidad media del viaje completo es 885 centímetros por segundo.
the distance between a boy and a hill is 250 meters. if the boy shouts after how long will the echo be heard numerical problem
Answer:
1.47 s
Explanation:
From the question,
s = 2d/t................... Equation 1
s = speed of sound in air, d = distance between the boy and the hill, t = time to hear the echo.
make t the subject of the equation
t = 2d/s............... Equation 2
Given: d = 250 meters
Constant: s = 340 m/s
Substitute these values into equation 2
t = (2×250)/340
t = 500/340
t = 1.47 s
A car starts from rest with an acceleration of 5.0 m / s² and travels a distance of 1.0 km. What is the speed value of this car?
Answer:
100 m/s
Explanation:
We'll begin by converting 1 km to m. This can be obtained as follow:
1 km = 1000 m
Finally, we shall determine the final velocity of the car. This can be obtained as follow:
Initial velocity (u) = 0 m/s
Acceleration (a) = 5.0 m/s²
Distance (s) = 1000 m
Final velocity (v) =?
v² = u² + 2as
v² = 0² + (2 × 5 × 1000)
v² = 0 + 10000
v² = 10000
Take the square root of both side
v = √10000
v = 100 m/s
Therefore, the speed value of the car is 100 m/s.
