Answer:

Explanation:

Forces can change speed of motion, the more force that's applied when you push a ball for example, the faster the ball will go. Force can also change the shape of objects by applying pressure to them too. The inertia from force can change direction, as when you let's say hit a tennis ball, it won't go perfectly straight. So all of the above are correct

How can you tell if an igneous rock has an intrusive or extrusive origin?

wariber [46]

Intrusive igneous rocks cool down from magma slowly because they form underneath the surface, that will make them have large crystals.

Extrusive igneous rocks cool down from lava rapidly because they form at the surface, so that will make them have small crystals.

the electric current in a wire is 1.5 A. How many electrons flow past a given point in a time of 2 s?

34kurt

Answer:

The quantity of electrons that flows past a given point is 3.0 C.

Explanation:

An electric current (I) is the ratio of the quantity of charges (Q) that flows through a point to the time taken (t).

i.e I = $\frac{Q}{t}$

It is measured in Ampere's by the use of an ammeter in the laboratory. The quantity of charge that flow through a given point is measured in Coulombs, while time is measured in seconds.

Given that; I = 1.5A and t = 2s, find Q.

Q = It

= 1.5 × 2

= 3.0 C

The quantity of electrons that flows past a given point is 3.0 C.
