Account for this, using energy concepts O For each meter of the load is raised, 2 m of rope must be pulled up. O For each meter of the load is raised, 2.5 m of rope must be pulled up For each meter of the load is raised, 1.5 m of rope must be pulled up. O For each meter of the load is raised, 0.5 m of rope must be pulled up. Submit Request Answer Provide Feedback
Two metres of rope must be raised in order to move the burden every metre.
Explain why two metres of rope should be raised.
Assuming no dissipative forces are at work over the rope.
The effort is used to draw upward on the rope's free end while the load is hung from the pulley block. The effort required is just half the amount of the load because the load is now suspended from two ropes, each of which is bearing half of the weight.
Hence, two metres of rope must be raised in order to move the burden every metre.

A 90 g mass is attached to one end of a 10-cm-long spring. The other end of the spring is connected to a frictionless pivot on a frictionless, horizontal surface. Spinning the mass around in a circle at 90 rpm causes the spring to stretch to a length of 12 cm.
The spring constant of the spring is 6.66 N/m.
What is force?The definition of force in physics is: The push or pull on a massed object changes its velocity.
An external force is an agent that has the power to alter the resting or moving condition of a body. It has a direction and a magnitude.
The rotational speed of the 90 g = 0.09 kg mass is: ω = 90 rpm
= 90×2π/60 radian/second.
= 3π radian/second.
So centripetal force acting on the spring = mω²r
This causes the spring to stretch to a length of 12 cm = 0.12 m.
Hence, spring constant: k = mω²r/0.12 = 0.09×(3π)²×0.10/0.12 N/m = 6.66 N/m.

Compared to visible light, radio waves are less energetic and move more slowly.
The speed of light, which is roughly 186,000 miles per second, is what radio waves move at. In other words, light may go farther than the entire globe in the same amount of time that radio waves take to cover the distance of a football field. The speed and energy of radio waves would be slower than those of visible light. Compared to radio waves, visible light would have a shorter wavelength and lesser energy. The speed of radio waves and the speed of light in the visible spectrum are identical. In a vacuum, they both move at a speed of 3 108 3 10 8 metres per second. The visible light that our eyes detect is electromagnetic radiation of this kind.

g a projectile is shot directly away from earth's surface. neglect the rotation of the earth. what multiple of earth's radius gives the radial distance the projectile reaches if its initial speed is 0.745 of the escape
The multiple of earth's radius which gives the radial distance is 4/3 or 1.33.
Initial speed = 0.745
However,
We know that escape velocity = V = √ (GM/2Rₓ)
So, using the property of energy conservation,
= (1/2)mv² - GMm/2Rₓ
= - GMm/r
The escape velocity, in astronomy and space exploration, is the velocity needed for a body to escape from a gravitational centre of attraction without undergoing any further acceleration. It is the minimum velocity required by a body to be projected to overcome the gravitational pull of the earth.

in Section 24-2. you learned how Neptune is afferent from Uranus, and how its rings and moons fomed and evolved Based on what you leamed about Uranus select all of the correct statements from the following list Neptune is similar to Uranus as far as sze, mass, composition and interior structure Lke Uranus, Neptune shows very little atmospheric activity Neptune's largestmoon Triton, has a retrograde orbit which suggests that it was captured i Beng much farther from the sun. Nepture has less internal heat than Uranus Triton has a tin atmosphere and may be geologically active Lke Uranus. Neptune's solid core prevented from having a magnetic field Neptune's position was predicted before it was discovered
Neptune and Uranus are similar in terms of size, mass, composition, and internal structure. The largest moon of Neptune, Triton, appears to have been captured because of its retrograde orbit.
Triton has a thin atmosphere and could be experiencing geological activity. Neptune's location was anticipated before it was ever discovered. Neptune is one of just two ice giants in the outer solar system (the other is Uranus). The planet's bulk, which is composed of a hot, dense fluid floating atop a tiny, rocky core, is primarily made up of water, methane, and ammonia (80% or more). Uranus is Neptune's identical twin. Their mass and chemical contents are equivalent. They are composed of an exterior layer of rocks and a mantle that is a mixture of water, ammonia, and methane ices.
Therefore, a physical body's mass is its total amount of matter. Inertia, or the body's resistance to acceleration (change of velocity) when a net force is applied, is also measured by this property. The gravitational pull an object has on other bodies is also influenced by its mass. The kilograms is the fundamental mass unit of SI (kg).

two pool balls, each moving at 2 m/s, roll toward each other and collide. suppose after bouncing apart, each moves at 2 m/s. assume the positive direction is to the right. this collision violates conservation of a. kinetic energy b. momentum c. both kinetic and momentum d. none of the above
Answer:
(D) From what has been given
For a linear elastic collision the speed of separation equals the speed of approach - if the relative speed of approach was 4 m/s, the relative speed of separation will be 4 m/s - both KE and momentum are considered conserved
