Una rueda que tiene 15 cm de radio, realiza 64 vueltas en 16 seg. Calcula: Periodo Frecuencia Velocidad angular Velocidad lineal
Answer:
i) El período de la rueda es de 0,25 segundos.
ii) La frecuencia de la rueda es 4 Hertz
iii) La velocidad angular es aproximadamente 25.133
iv) La velocidad lineal es de aproximadamente 3,77 m / s
Explanation:
El radio de la rueda, r = 15 cm = 0,15 m
El número de vueltas que hace la rueda = 64 vueltas
El tiempo que tarda el volante en dar 64 vueltas = 16 segundos
i) El período = El tiempo que tarda la rueda en dar 1 vuelta
∴ El período de la rueda, T = 16 segundos/(64 vueltas) = 0,25 segundos
El período de la rueda, T = 0,25 segundos
ii) La frecuencia = El número de vueltas por segundo
∴ La frecuencia de la rueda, f = 64 vueltas /(16 segundos) = 4 Hertz
1 vuelta = 2 · π radianes
La frecuencia de la rueda, f = 4 Hertz
iii) Velocidad angular = La medida del ángulo girado por segundo
∴ La velocidad angular, ω = 64 × 2 × π/16 segundos ≈ 8 · π rad/segundos ≈ 25.133 rad/seg
La velocidad angular, ω ≈ 25.133
iv) La velocidad lineal, v = r × ω
∴ v = 0,15 m × 8 · π rad / segundos ≈ 3,77 m/s
La velocidad lineal, v ≈ 3.77 m/s

when water change into ice it contracts or expand
plz answer fast..
Answer:Yes, water indeed expands when it changes form from liquid to solid. And this is because water has a property called “hydrogen bonds”, and these bonds occur between each water molecule. But when water is in a liquid form these hydrogen bonds break more easily and occur less frequently. When the temperature drops the kinetic energy also drops, which in turn makes hydrogen bonds form more frequently. So the water molecules form a lattice, which is less dense than regular liquid water.

¿A qué altura se podría haber elevado un cuerpo de 100 kilogramos de peso con esa misma energía? Rta=3673.5m
Respuesta:
3673.5m
Explicación:
Falta el dato de energía para poder resolver el problema pero vamos a suponer un dato para ver el procedimiento.
Supongamos que se emplean 3600030 J para elevar un cuerpo de 100 kg una cierta altura, aumentando su energía potencial. Los datos son:
Energía potencial (Ep): 3,600,030 JMasa del cuerpo (m): 100 kgGravedad terrestre (g): 9.8 m/s²Para calcular la altura alcanzada (h), podemos usar la siguiente fórmula.
Ep = m × g × h
h = Ep/m × g
h = 3,600,030 J/100 kg × 9.8 m/s² = 3673.5m

If a ball takes 12 seconds to hit the ground, how fast was it falling when it hit the ground?
Answer:
Roughly around 117.6 mph
Explanation
To find out something's speed (or velocity) after a certain amount of time, you just multiply the acceleration of gravity by the amount of time since it was let go of. So you get: velocity = -9.81 m/s^2 * time, or V = gt. The negative sign just means that the object is moving downwards.

at what distance from a -5.35*10^-6 C charge will the electric potential be -500 v?
Answer:
Different values of Q will make different values of electric potential V (shown in the image). The electric potential arising from a point charge Q, at a distance r from the charge is observed to be where ε0 is the permittivity of vacuum. VE is known as the Coulomb potential .Explanation:
The distance from the -5.35 × 10⁻⁶ C charge where the electric potential is -500 V is approximately 0.0935 meters or 9.35 cm.
To determine the distance from a charge where the electric potential is -500 V, we can use the formula for electric potential due to a point charge:
V = k × (Q / r)
Where:
V is the electric potential (in volts),
k is the Coulomb's constant (approximately 8.99 × 10⁹ Nm²/C²),
Q is the charge (in coulombs), and
r is distance from the charge (in meters).
Rearranging the formula, we solve for the distance:
r = k × (Q / V)
Substituting the given values into the equation
k = 8.99 × 10⁹ Nm²/C²,
Q = -5.35 ×10⁻⁶ C, and
V = -500 V,
r = (8.99 × 10⁹ Nm²/C²) × (-5.35 × 10⁻⁶ C / -500 V)
Calculating this expression:
r ≈ 0.0935 meters or 9.35 cm
Therefore, the distance from the -5.35 × 10⁻⁶ C charge where the electric potential is -500 V is approximately 0.0935 meters or 9.35 cm.

A 3.09 x 10-4 T magnetic field points directly east. A loop of area 0.0471 m2 faces directly northeast. What is the magnetic flux through the loop?
Answer:
1.03 * 10^-5
Explanation:
The magnetic flux through the loop is approximately 1.317 × [tex]10^{(-5)[/tex]T·m².
To calculate the magnetic flux through a loop, we use the formula:
Φ = B × A × cos(θ)
Where:
Φ is the magnetic flux
B is the magnetic field strength
A is the area of the loop
θ is the angle between the magnetic field and the normal to the loop
Given:
Magnetic field strength (B) = 3.09 × [tex]10^{(-4)[/tex] T (east direction)
Area of the loop (A) = 0.0471 m²
The loop faces directly northeast
To find the angle θ, determine the angle between the magnetic field direction (east) and the normal to the loop (northeast).
Since the loop faces northeast, the angle between the normal to the loop and the east direction is 45 degrees (90 degrees divided by 2).
Now calculate the magnetic flux:
Φ = B × A × cos(θ)
Φ = (3.09 × [tex]10^{(-4)[/tex] T) × (0.0471 m²) × cos(45°)
Using the value of cos(45°) as 0.7071:
Φ = (3.09 × [tex]10^{(-4)[/tex] T) × (0.0471 m²) ×0.7071
Φ = 1.317 × [tex]10^{(-5)[/tex] T·m²
Therefore, the magnetic flux through the loop is approximately 1.317 × [tex]10^{(-5)[/tex] T·m².

5. Draw connections: The uranium fission reactions are triggered by a neutron, and each
reaction produces two or three more neutrons. What do you think will happen next?
114
TA
Answer:
The neutrons released in the 1st fission reaction will trigger more fission reactions to occur., thus creating a chain reaction.
The fission reaction is a chain reaction. When the fissile nucleus is bombarded with a neutron, more neutrons are produced and the reaction continues indefinitely.
One of the types of artificial radioactive decay is nuclear fission. Nuclear fission occurs when a fissile nucleus is bombarded with a nucleus. When this occurs, the nucleus is broken up into smaller fragments called daughter nuclei and energy is produced.
Also, more neutrons are produced that can continue to bombard more of the fissile material in order to continue the reaction. As a result of this, nuclear fission is often referred to as a chain reaction because it is self sustaining.

Three children are throwing a disc in the park. The first child throws the disc 32 m [W 14° S] to the second child, who then throws the disc 15 m [E 62° S]. What is the net displacement of the disc?
*the answer is 32m (W 41 S) Please explain how to do this....
NO LINKS I WILL REPORT U
Answer:
Evidently W 14 S means West and to the South by 14 deg
If you draw the X-Y coordinates and enter this value
Tx1 = - 32 * cos 14 = -31 (along the negative x-axis)
Ty1 = -32 * sin 14 = -7.4 (along the negative y-axis)
Likewise
Tx2 = 15 * cos 62 = 7.04
Ty2 = -15 * sin 62 = -13.2
Tx = -31 + 7.04 = -24
Ty = -7.4 - 13.2 = -20.6
Final distance = (24^2 + 20.6^2)^1/2 = 31.6 m
Direction will be South of West
tan -20.6 / -24 = 41 deg

If the starting velocity was 0 m/s and the final velocity was -7.68 m/s, what is the average velocity of the rock?
Answer:
Average velocity = -3.84 m/s
Explanation:
Given the following data;
Initial velocity = 0 m/s
Final velocity = -7.68 m/s
To find the average velocity;
Average velocity = (U + V)/2
Average velocity = (0 + [-7.68])/2
Average velocity = -7.68/2
Average velocity = -3.84 m/s
Therefore, the average velocity of the rock is -3.84 meters per seconds.
