Put the values.
The force towards the circle is 120 N.
What is centripetal force?
Centripetal force is the pressure that acts on the frame to preserve it from shifting in a curved direction. Centripetal force is an actual force that is directed inward closer to the center of rotation. In easy phrases, whilst twirling an object tied to a string, the string will exert an inward centripetal force on the item.
calculation:-
⇒ mass of object = 5 kg,
⇒radius =6 m,
ω = 2 radian/s

The velocity of the block isv3 = 1. 4 m/s atc. The block moves on tod, where it stops. The spring constant of the spring is closest to
Answers
The spring constant of the spring is closest to 210 N/m.
First, let's calculate the potential energy stored in the spring:
PE = 1/2 k x^2
Therefore:
x = F_ext / k = 67 N / k
and:
\(PE = 1/2 k (67 N / k)^2 = 2244.5 J/k\)
Next, let's calculate the kinetic energy of the block at point b:
\(KE\_b = 1/2 m v2^2 = 0.5 * 0.8 kg * (1.9 m/s)^2 = 1.216 J\)
The work done by friction over the rough section is given by:
\(W\_f = f\_k * d\)
The frictional force is:
f_k = μ_k * m * g
Substituting the given values, we get:
\(f\_k = 0.39 * 0.8 kg * 9.81 m/s^2 = 3.06 N\)
The distance traveled over the rough section is:
\(d = h\_b - h\_c = 0.3 m - 0.1 m = 0.2 m\)
Therefore:
\(W\_f = 3.06 N * 0.2 m = 0.612 J\)
Finally, let's calculate the kinetic energy of the block at point c:
\(KE\_c = 1/2 m v3^2 = 0.5 * 0.8 kg * (1.4 m/s)^2 = 0.392 J\)
Using the principle of conservation of mechanical energy:
\(PE = KE\_b + KE\_c + W_f\)
Solving for k, we get:
\(k = 2 * (KE\_b + KE\_c + W_f) / (67 N / k)^2\)
Substituting the given values, we get:
\(k = 2 * (1.216 J + 0.392 J + 0.612 J) / (67 N / k)^2 = 210 N/m\)

Responder:
12230825.435 pascal
Explicación:
Dado que:
Peso (W) = 180 libras
Número de tacos = 10
Área por montante = 0.01 in²
Área total (10 * 0.01) = 0.1 pulg²
Usando la calculadora de conversión:
180 libras = 81.647 kg
0.1 pulg² = 6.452 × 10 ^ -5 m²
Recordar :
Presión = Fuerza (Newton) / Área (m²)
Fuerza = masa * aceleración debida a la gravedad
Aceleración por gravedad = 9,8 m / s²
Presión = (81.647 * 9.8) / (6.452 * 10 ^ -5)
Presión = 800.1406 / 6.452 * 10 ^ -5
Presión = 12230825.435 pascal

Answers
Seismic and light waves can be placed on the electromagnetic spectrum, which is a range of wavelengths that includes visible light, radio waves, and X-rays.Option (d)
Firstly, seismic waves and light waves are both forms of energy that travel through space. Seismic waves are generated by the movement of tectonic plates beneath the Earth's surface, while light waves are produced by the emission of electromagnetic radiation from the sun or other sources.
Secondly, both types of waves move outward from their source and propagate through a medium, whether it is air, water, or rock. Seismic waves can be either compressional (P-waves) or transverse (S-waves), while light waves are transverse electromagnetic waves.
Thirdly, both types of waves travel at a constant speed in a vacuum, but their speed changes when they travel through different mediums. Seismic waves travel faster through denser materials, while light waves travel slower.
Finally, both seismic and light waves can be placed on the electromagnetic spectrum, which is a range of wavelengths that includes visible light, radio waves, and X-rays.

What is Newton's First Law (Inertia)?Newton's First Law of Motion is also referred to as Law of Inertia and it states that an object in motion would continue in its state of motion at continuous velocity (same speed and direction) or if at rest, it will remain at rest unless it is acted upon by an external force.
This ultimately implies that, the amount of net force keeping a physical object moving at a constant speed and in a specific direction is always equal to zero (0) newton in accordance with Newton's First Law of Motion.
In this context, we can reasonably infer and logically deduce that a physical object that has a higher mass would have more inertia, which causes it to either experience a slower motion or speed up less quickly.

A metal surface is illuminated by light with a wavelength of 350 nm . The maximum kinetic energy of the emitted electrons is found to be 1.90 eV .
What is the maximum electron kinetic energy if the same metal is illuminated by light with a wavelength of 250 nm ?
Answers
We can expect the maximum electron kinetic energy to be higher when illuminated by light with a wavelength of 250 nm compared to 350 nm.
The phenomenon of light causing the emission of electrons from a metal surface is known as the photoelectric effect. The energy of the incident photons determines the maximum kinetic energy of the emitted electrons.
In this case, when the metal surface was illuminated by light with a wavelength of 350 nm, the maximum kinetic energy of the emitted electrons was found to be 1.90 eV. Now, if the same metal is illuminated by light with a shorter wavelength of 250 nm, the energy of the incident photons would increase.
This would result in a higher maximum kinetic energy of the emitted electrons, as per the photoelectric effect. Therefore, we can expect the maximum electron kinetic energy to be higher when illuminated by light with a wavelength of 250 nm compared to 350 nm.

As per the question, the objects having unlike charges would attract one another more when we 'escalate the positive charge of the object having a positive charge and enhance the negative charge of the object possessing negative charge.' This will lead the atoms that are losing electrons to be positively(+ve) charged and the atoms gaining electrons to be negatively

what is the moment of inertia perpendicular to and through the center of of a thin rod of mass mm and uniform density if dd is the distance from the center of the rod to one of its ends?
Answers
The moment of inertia perpendicular to and through the center of a thin rod of mass m and uniform density, with a distance d from the center to one of its ends, is (1/3) * m * d².
What is the moment of inertia of a thin rod?The moment of inertia of a thin rod can be calculated using the formula:
Moment of inertia = (1/3) * mass * distance²
In this case, the mass of the rod is represented by m, and the distance from the center to one of its ends is represented by d. By substituting these values into the formula, we find that the moment of inertia is equal to (1/3) * m * d².
The moment of inertia describes the rotational inertia of an object, indicating how resistant it is to changes in its rotational motion. For a thin rod, the moment of inertia depends on its mass and the distance of its mass distribution from the axis of rotation.
The formula (1/3) * m * d² represents the specific moment of inertia for a thin rod with uniform density, where m is the mass and d is the distance from the center to one of its ends.

Answers
Answer: The momentum value for both big rig and sport utility vehicle are the same as 16000 pound mph
Explanation:
The momentum of the truck is:
p = mv
p = (36,000 kg)(0.89 m/s)
p = 32,000 kg • m/s
p is 32,000 because when multiplying two numbers your answer uses the same amount of sig figs as the number with the lowest amount of sig figs. Here, both the mass and the velocity have 2 SFs so the answer has 2 SFs.
p = mv
p = (1,800 kg)(18 m/s)
p = 32,000 kg • m/s
32,000 = 32,000 so the momentum is equal

How can we calculate the source strength is required to simulate flow around the body?To calculate the source strength is required to simulate flow around the body we are using the formula here is,
v= m/2*π*b
Or, m= 2*π*b*v
Here we are given,
b= The thickness of a certain body has the shape of a half-body = 2*r = 2* 0.5 = 1 m
v = The velocity of the object. = 15 m/s.
We have to calculate the values of the source strength is required to simulate flow around the body = m kg
Now we put the values in above equation we get,
m= 2*π*b*v
Or, m= 2*π*1*15
Or, m= 94.2 kg
