A spring of k=500 N/m that is initially compressed 2m is used to launch a 100N load of bricks up a 2 m tall
hill. Find the speed of the bricks at the top of the hill.
e. What would the speed at the top of the hill be with 2m of initial compression if 15% of the energy is
dissipated through friction?
Speed of the bricks at the top of hill is calculated as 6.26 m/s. e) speed of the bricks at top of hill with 2 m of initial compression and 15% energy dissipation is calculated as 13.04 m/s.
What is energy?The capacity or power to do work, like the capacity to move any object by the application of force is called energy.
Initial potential energy of compressed spring:
Ep = 1/2 kx^2 = 1/2 * 500 N/m * (2 m)^2 = 1000 J
Here, k is spring constant, x is compression of the spring, and J is unit of energy in joules.
Final potential energy of the bricks:
Ep = m g h = 100 N * 9.81 m/s^2 * 2 m
= 1962 J
As, Ep = Ep
1/2 kx^2 = m g h
v = sqrt(2gh) = sqrt(2 * 9.81 m/s^2 * 2 m) = 6.26 m/s
Therefore, speed of the bricks at the top of the hill is 6.26 m/s.
e. If 15% of energy is dissipated through friction, final kinetic energy of the bricks at the top of hill will be 85% of initial potential energy of compressed spring.
0.85 * 1000 J = 1/2 mv^2
v = sqrt(170 / 1)
= 13.04 m/s
Therefore, speed of bricks at the top of the hill with 2 m of initial compression and 15% energy dissipation is 13.04 m/s.

NMR active nuclei act in a way that causes them to absorb and emit electromagnetic radiation when placed inside of a magnetic field. This allows them to be used to measure the magnetic properties of the sample.
What is the radiation ?Radiation is a form of energy that is released from an atom in the form of electromagnetic waves or particles. It occurs naturally, such as from the sun, and can also be generated artificially, such as through medical or industrial processes. Radiation is all around us, and takes many forms. It can be either ionising or non-ionising radiation. Ionising radiation has enough energy to remove electrons from atoms, thus creating ions. This type of radiation is known to be hazardous and can damage living tissue, such as cells in the body. Non-ionising radiation, on the other hand, does not have enough energy to damage tissue and is therefore considered less hazardous. Examples of non-ionising radiation are radio waves, microwaves and visible light.

A bowling ball weighs 645 N.
What is the mass of the
bowling ball?
n = [?] kg
m
Answer:
Explanation:
To find the mass of an object, we can use the formula:
mass (m) = force (f) / acceleration (a)
Since the force on an object is equal to its weight, which is the force of gravity acting on it, we can use the equation:
mass (m) = weight (f) / acceleration (a)
where weight (f) = 645 N and acceleration (a) is the acceleration due to gravity, which is approximately 9.8 m/s^2 on the surface of the Earth.
So, we have:
mass (m) = 645 N / 9.8 m/s^2 = 66 kg
Therefore, the mass of the bowling ball is 66 kg.
A bowling ball weighs 645 N. then the mass of the bowling ball is 65.8 kg. Weight is gravitational force acting on the ball.
Given,
Weight W = 645 N
Acceleration due to gravity g = 9.8 m/s²
mass m = ?
The weight of the object is given by,
W = mg
645 = m*9.8
m = 65.8 Kg
Hence mass of the ball is 65.8 kg

The magnetic flux (B) is calculated to be -6.15×10^-5 T in the -xx-direction.
The magnetic force on a charged particle moving in a magnetic field is given by:
F = qvBsinθ
where q is the charge of the particle, v is its velocity, B is the magnetic field, and θ is the angle between the velocity and the magnetic field.
In this problem, the particle is moving parallel to the yy-axis, so its velocity vector is in the +yy-direction. The magnetic field is in the +xx-direction due to the current in the wire. Therefore, the angle between the velocity and the magnetic field is 90 degrees, and sinθ = 1.
The magnetic force on the particle is given by:
F = qvB
The acceleration of the particle is related to the net force acting on it by:
F = ma
where m is the mass of the particle and a is its acceleration.
Combining these equations, we have:
qvB = ma
Solving for B, we get:
B = (ma)/(qv)
Substituting the given values, we get:
B = [(4.00×10^-6 kg) × (-5.00×10^3 m/s^2)] / [(8.00×10^-3 C) × (65.0 A)]
B = -6.15×10^-5 T
The negative sign indicates that the magnetic field is in the opposite direction to the +xx-direction of the wire, which means that it is in the -xx-direction.

Una pelota de plástico de 12. 3 g cuelga de un hilo de 28. 6 cm que esta sujeto a una pared vertical. Un campo eléctrico se encuentra en el cuarto. Cuando se le da a la pelota una carga de -1. 11 mC, se observa que permanece suspendida haciendo un ángulo de 17. 4° entre el hilo y la pared. ¿Cuál es la magnitud del campo eléctrico y su dirección?
La magnitud del campo eléctrico es de 4.03 x 10⁶ N/C y su dirección es perpendicular a la pared y hacia arriba.
How to determine Campo electricoEl campo eléctrico es de 12,29 N/C con dirección hacia arriba. Esto se calcula usando el principio de conservación de la energía, el cual afirma que el trabajo realizado para cargar la pelota de plástico de 12,3 g con una carga de -1,11 mC es igual al trabajo necesario para sostenerla en un ángulo de 17,4° con el hilo de 28,6 cm.
Así, la magnitud del campo eléctrico se calcula usando la siguiente fórmula:
E = W/q
= (mgh x sin(θ))/q
= (0,0123 x 9,81 x 28,6 x sin(17,4°))/(-1,11x10⁻³)
= 12,29 N/C
La magnitud del campo eléctrico se puede encontrar utilizando la ley de Coulomb y la trigonometría. La ley de Coulomb establece que la fuerza eléctrica entre dos cargas es igual a la constante de Coulomb (k) multiplicada por el producto de las dos cargas dividido por la distancia entre ellas al cuadrado.
En este caso, la fuerza eléctrica es igual a la fuerza gravitacional, ya que la pelota permanece suspendida. Por lo tanto, podemos escribir:
Fe = Fg
k x q₁ x q₂ / r² = m x g
Donde Fe es la fuerza eléctrica, Fg es la fuerza gravitacional, q₁ y q₂ son las cargas, r es la distancia entre ellas, m es la masa de la pelota y g es la aceleración debida a la gravedad.
Utilizando la trigonometría, podemos encontrar la distancia entre la pelota y la pared, que es igual a la longitud del hilo multiplicada por el coseno del ángulo entre el hilo y la pared. Por lo tanto, r = 28.6 cm x cos(17.4°) = 26.9 cm.
Sustituyendo los valores conocidos en la ecuación y resolviendo para q_2, obtenemos:
q₂ = (m x g x r²) / (k xq1)
q₂ = (12.3 g x26.9 cm²) / (9 x 10⁹ N x m²/C² x -1.11 x 10⁻³ C)
q₂ = -2.99 x 10⁻⁶ C
La magnitud del campo eléctrico es igual a la fuerza eléctrica dividida por la carga, por lo que:
E = Fe / q₂
E = (m x g) / q₂
E = (12.3 g x 9.8 m/s²) / (-2.99 x 10⁻⁶ C)
E = -4.03 x 10⁶ N/C
La dirección del campo eléctrico es perpendicular a la pared y hacia arriba, ya que la pelota está suspendida y la fuerza eléctrica es igual a la fuerza gravitacional.
En conclusión, la magnitud del campo eléctrico es de 4.03 x 10⁶ N/C y su dirección es perpendicular a la pared y hacia arriba.

imagine a planet moving in a perfectly circular orbit around the sun. is this planet experiencing acceleration?
Yes, the planet is experiencing acceleration. If we imagine a planet moving in a perfectly circular orbit around the sun. is this planet experiencing acceleration?
Acceleration is defined as the rate of change of velocity, and since the planet is moving in a circular orbit, it is constantly changing its direction, resulting in an acceleration towards the center of the orbit. This is known as centripetal acceleration, and it is what keeps the planet in its circular path and prevents it from flying off into space. The magnitude of this acceleration depends on the speed of the planet, its distance from the sun, and the mass of the sun.
In conclusion, even though the planet is moving in a circular path and its speed may not be changing, its direction is constantly changing, causing it to experience acceleration. This centripetal acceleration ensures that the planet remains in its orbit around the sun.

what is third variable problem?
