Answer:

procedural memory

Explanation:

The procedural memory is where we keep, the more or less automatic learning, escaping consciousness. Essentially motor skills and processes, such as writing or cycling. No one thinks of the sequence of movements we have to perform so that we can ride a bicycle, nor can we describe in words how to do it. It's automatic, which is beyond our consciousness, so we don't need to think to do it.

Explain why ionic compounds are neutral even though they are made up of charged particles
Lelechka [254]
Ionic compounds are made up of two charged species, a cation (+) and an anion (–).

The charges must balance out to zero for a stable ionic compound, because ionic bonds are formed between two charged species. They form in ratios according to their charges to balance out.

A man does 500 J of work pushing a car a distance of 2 m. How much force does he apply? Assume there is no friction.
Dmitry [639]

The correct answer is A. 250N

Work is a product of force and distance.

That is, work done=force×distance

Therefore substituting for the values in the question:

500J=force×2m

force= 500Nm/2m=250N

another unit for work done is Nm as force as the SI unit of force is newtons and distance in meters

1. A spring extends by 10 cm when a mass of 100 g is attached to it. What is the spring constant? (Calculate your answer in N/m)
cupoosta [38]

Answer:

1) k = 10 [N/m]

2) a-) x = 0.4 [m]

b)  x = 0.075 [m]

Explanation:

To be able to solve this type of problems that include springs we must use Hooke's law, which relates the force to the deformed length of the spring and in the same way to the spring coefficient.

F = k*x

where:

F = force [N] (units of Newtons]

k = spring constant  [N/m]

x = distance = 10 [cm] = 0.1 [m]

Now, the weight is equal to the product of the mass by the gravity

W = m*g = F

where:

m = mass = 100 [g] = 0.1 [kg]

g = gravity acceleration = 10 [m/s²]

F = 0.1*10 = 1 [N]

Now clearing k

k = F/x

k = 1/0.1

k = 10 [N/m]

2)

a ) if the force is 4 [N]

clearing x

x = F/k

x = 4/10

x = 0.4 [m]

m = 75 [g] = 0.075 [kg]

W = m*g = F

F = 0.075*10 = 0.75 [N]

x = .75/10

x = 0.075 [m]

Newton’s first law says that if motion changes, then a force is exerted. Describe a collision in terms of the forces exerted on
ira [324]

Answer:

In collision between equal-mass objects, each object experiences the same acceleration, because of equal force exerted on both objects.

Explanation:

In a collision two objects, there is a force exerted on both objects that causes an acceleration of both objects. These forces that act on both objects are equal in magnitude and opposite in direction.

Thus, in collision between equal-mass objects, each object experiences the same acceleration, because of equal force exerted on both objects.

two identical steel balls mounted on wooden posts initially have different amounts of charge, one with -14uC and the other with
GrogVix [38]

According to the Law of Conservation of Charge, the net charge remains constant. If both things have different charges, upon contact, they would share the charge equally. In this case, the total charge is -16μC. The final charge for each ball would be -8 μC.
