Answer:The lines of force in a magnet is closer together at the ends of a bar magnet.

Explanation:Is equally strong at the north pole when compared with the south pole. The force is weaker in the middle of the magnet and halfway between the pole and the center.

Answer:

atoms that no longer have a neutral charge are called ions!

Explanation:

when atoms gain or lose electrons, they become either negatively charged or positively charged in the process. losing electrons means the atom becomes more positive, therefore positively charged. gaining electrons means the atom becomes more negative, so negatively charged. atoms that go through this process of gaining or losing electrons are called ions.

Answer:

Higher cliffs don't accelerate your fall  acceleration is constant during free fall. The pull of gravity decreases infinitesimally at higher elevations, but it pulls you with an equal force from the first second of you jump off until you decelerate when you fall hit the water. hope this helped

Answer:

23.41 N

Explanation:

Formula to find elastic potential energy is, P.E=0.5*k*delta x^2

Where, P.E. = Elastic potential energy

k is the spring constant

delta x is the length of the stretched spring.

So, P.E.=0.5*180*0.51^2 = 23.41 N

Answer:

In mechanics, acceleration is the rate of change of the velocity of an object with respect to time. Accelerations are vector quantities. The orientation of an object's acceleration is given by the orientation of the net force acting on that object

Answer:

60 km/h

~16.7 m/s

Explanation:

speed= s1-s0/t1-t0

speed= 300-0/5-0= 60 km/h

60 km/h / 3.6 = ~ 16.7 m/s

Answer:

it is 60 kmh

Explanation:

it is 60 kmh because 300÷ 5=60

Answer:Gravity is the force among the options listed that has not directly changed Earth's surface.

Explanation:

Gravity is a fundamental force that acts on all objects with mass, including the Earth itself, but it does not cause changes or modifications to the Earth's surface features. Instead, gravity influences the movement of materials and the shape of the Earth's surface by exerting a pulling force on objects. On the other hand, folding, erosion, and weathering are all processes that directly contribute to shaping

The group which was designed to study Saturn is C. Voyager 1, Huygens, and Cassini. It was a collaborative mission involving NASA, ASI, and ESA.

The trio of Voyager 1, Huygens, and Cassini embarked on groundbreaking missions, collectively enhancing our understanding of Saturn and its diverse moons. Launched by NASA in 1977, Voyager 1 ventured into the outer solar system, conducting close flybys of Jupiter and Saturn, capturing detailed imagery and valuable scientific data.

Huygens, a constituent of the collaborative Cassini-Huygens mission involving NASA, ESA, and ASI, made a historic touchdown on Saturn's moon Titan in 2005. It meticulously examined Titan's atmosphere and surface, yielding unprecedented insights.

Meanwhile, the Cassini spacecraft, another integral part of the Cassini-Huygens mission, meticulously orbited Saturn for more than 13 years. Cassini extensively studied Saturn's rings, atmosphere, and numerous moons, unraveling captivating discoveries such as new moons and tempestuous storms.

The Cassini mission culminated with a planned atmospheric entry into Saturn. These missions collectively revolutionized our knowledge of Saturn, its enigmatic rings, and its captivating moons.

Answer:

An accelerometer is a tool that measures proper acceleration.[1] Proper acceleration is the acceleration (the rate of change of velocity) of a body in its own instantaneous rest frame;[2] this is different from coordinate acceleration, which is acceleration in a fixed coordinate system. For example, an accelerometer at rest on the surface of the Earth will measure an acceleration due to Earth's gravity, straight upwards[3] (by definition) of g ≈ 9.81 m/s2. By contrast, accelerometers in free fall (falling toward the center of the Earth at a rate of about 9.81 m/s2) will measure zero.

Accelerometers have many uses in industry and science. Highly sensitive accelerometers are used in inertial navigation systems for aircraft and missiles. Vibration in rotating machines is monitored by accelerometers. They are used in tablet computers and digital cameras so that images on screens are always displayed upright. In unmanned aerial vehicles, accelerometers help to stabilise flight.

When two or more accelerometers are coordinated with one another, they can measure differences in proper acceleration, particularly gravity, over their separation in space—that is, the gradient of the gravitational field. Gravity gradiometry is useful because absolute gravity is a weak effect and depends on the local density of the Earth, which is quite variable.

Single- and multi-axis accelerometers can detect both the magnitude and the direction of the proper acceleration, as a vector quantity, and can be used to sense orientation (because the direction of weight changes), coordinate acceleration, vibration, shock, and falling in a resistive medium (a case in which the proper acceleration changes, increasing from zero). Micromachined microelectromechanical systems (MEMS) accelerometers are increasingly present in portable electronic devices and video-game controllers, to detect changes in the positions of these devices.
