Answer:

  none

Explanation:

Newton's first law says an object in motion will stay in motion at the same speed and direction unless acted upon by some force.

No force is necessary for the object to keep its speed and direction on a frictionless surface.

Westkost [7]

Answer:

33.6 m

Explanation:

Given:

v₀ = 0 m/s

a = 47.41 m/s²

t = 1.19 s

Find: Δx

Δx = v₀ t + ½ at²

Δx = (0 m/s) (1.19 s) + ½ (47.41 m/s²) (1.19 s)²

Δx = 33.6 m

A charge of 12 c passes through an electroplating apparatus in 2. 0 min. what is the average current?
NemiM [27]

The average current is 0.10 A.

<h3>Current </h3>

Charge moving through a location on a circuit at a constant rate is called current. When numerous coulombs of charge pass over a wire's cross section in a circuit, it produces a large current. It is not necessary for a wire to be moving at a fast speed in order to have a high current if the charge carriers are tightly packed into the wire. To put it another way, many charge carriers traveling through the cross section is sufficient; they do not need to travel a great distance in a single instant. The amount of charges that flow through a cross section of wire on a circuit, as opposed to how far they travel in a second, is what determines current.

What is the weight of an 1000 gram mass
Reil [10]

That depends on where you weigh it.

-- On the moon, it weighs 1.623 newtons (5.84 ounces).

-- On Jupiter, it weighs 24.79 newtons (5.57 pounds).

BTW ... 1,000 grams of mass is called ' one kilogram '.
