If a car is moving at 90 km/h and it rounds a corner, also at 90 km/h, does it maintain a constant speed? A constant velocity? I

valentina_108 [34]3 years ago
6 0

Answer:

Constant speed but different velocity

Explanation:

Since the car speed at the corner is 90km/h which is the same as before. The speed, or magnitude of the velocity vector, remains unchanged. The direction of the velocity vector, on the other hand, is changing as the car turns around the corner. Therefore, the car maintains a constant speed, but not a constant velocity.

What happens to energy and frequency of a wave if its wavelength increases?
Dahasolnce [82]

Answer:

Waves can be measured using wavelength and frequency. ... The distance from one crest to the next is called a wavelength (λ). The number of complete wavelengths in a given unit of time is called frequency (f). As a wavelength increases in size, its frequency and energy (E) decrease.

Sheena took the implicit association test (IAT) and found that she responded faster when ""strong"" words were paired with male
poizon [28]

Answer:

The finding suggests that

Sheena have an implicit belief that men are stronger than women.

Explanation:

Implicit Association Test:

In the field of social psychology, this test is used to determine the power of a person to associate between different objects in an implicit way. For example, are colored people good or bad?

  • So this test finding suggests that Sheena have an implicit belief that men are stronger than women by checking her response towards strong words.

According to newton's law of gravitation, what affects the force of attraction between two objects? distance between them angle
OlgaM077 [116]

The force of attraction between two objects Mass and distance.

<h3>What is newton's law of gravitation?</h3>

Every particle in the cosmos attracts every other particle with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centres, according to Newton's law of universal gravitation.

Inductive reasoning, as described by Isaac Newton, was used to deduce this general physical law from actual facts. It was created by Newton and is a component of classical mechanics. Philosophiae Naturalis Principia Mathematica, also known as "the Principia," was originally published on July 5, 1687. In April 1686, when Newton gave Book 1 of the unpublished book to the Royal Society, Robert Hooke said that Newton had learned the inverse square law from him.

According to the law, every point mass attracts every other point mass when a force applies along the line that intersects the two points, in today's parlance. The force is inversely equal to the square of the separation between the masses and directly proportional to their product.

F = G\frac{m_{1} m_{2}}{r^{2}  }

A 1.5 wire carries a 2 a current when a potential difference of 87 v is applied. What is the resistance of the wire
Dmitry_Shevchenko [17]

Ohm's law states that V = IR

                                   87 = 2 x R

                                    R = 87/2 ohms

Hope this helps :)

What causes changes of states in matter?
miv72 [106K]
Changes in state of matter would be a physical change to whatever it is that you are changing so I think it would be B.Molecules because in order for something to change the molecules have to be moving apart from one another but I maybe wrong depending on what it is your looking at
