Why do intrusive igneous rocks have large crystals?

1 answer:

3 0

The magma cools very slowly so that the crystals of different minerals have time to grow. The magma molecules in have time to organize themselves into crystal formations before the magma hardens. The naked eye helps the Intrusive rocks that has large crystals be seen.

nikitadnepr [17]

Answer:106560 N

Explanation:

Given

Let Tension between 2 and 3 car be $T_{23}$ and between 3 &4 is $T_{34}$

$T_{23}-T_{34}=ma$

mass of freight car =37,000 kg

acceleration of car $=0.48 m/s^2$

$T_{34}$ is accelerating all freights behind 3

therefore

$T_{34}=5\times ma$

$T_{34}=5\times 37000\times 0.48=88,800 N$

Thus

$T_{23}=T_{34}+ma$

$T_{23}=88,800+37000\times 0.48=88,800+17,760=106560 N$

Imagine that a car is traveling from your left to your right at a constant velocity. Which two actions could the driver take tha

Alona [7]

Answer:

(a). The speed of car will increases.

(b). The speed of car will decreases.

Explanation:

Given that,

A car is traveling from your left to your right at a constant velocity.

We need to find two actions could the driver take

Using given data

(a). If the velocity and acceleration of car to the right

It means the velocity and acceleration of car is in same direction then the speed of car will increases.

(b). If the velocity to the right and the acceleration to the left

It means the velocity and acceleration of car is in opposite direction then the speed of car will decreases.

Hence, (a). The speed of car will increases.

(b). The speed of car will decreases.
