Yes a igneous rock can be changed into another igneous rock. the reason behind it is when rocks melt they become magma or lava. when lava flows on the surface of the earth it crystallizes quickly and makes small crystals. but when they cool slower they make larger crystals. yes igneous rocks can change but only through extreme temperatures.
Answer:
This is a good experiment, however there are a few flaws
Explanation:
In this experiment, the battery is not replaced. Which can then affect the experiment if it had sustained damage from the failed attempts in the garage, and then being moved to the second scenario. Another possibility is that the battery was faulty from the start, which would definitely affect the results negatively.
Another flaw would be the temperature. The first scenario of a warm garage is fine, however after being moved to an environment below zero, the water in the car would have frozen, and many other systems would be impaired. Therefore the starting of the car would be influenced by more than just the battery.
Answer:
Force on the singly charged ion will be
Explanation:
We have given electric field E = 8 MN/C
So electric field in N/C will be
It is given that ion so charge on ion will be equal to
We have to find the electric force on the ion
Electric force is equal to , here q is charge and E is electric field
So force on the charge will be equal to
So force on the singly charged ion will be
Answer:
The length of the bridge during the hottest part of summer is
Explanation:
From the question we are told that
The length of the steel bridge is
The temperature for this length is
The temperature at summer
The coefficient of linear expansion is
Generally the change in length of the steel bridge is mathematically represented as
Substituting value
The length of the bridge in summer is mathematically evaluated as
Substituting values
<span>So, average angular velocity = angle/time = 90/1.5 = 60deg/second = (pi/3 radians/second) </span>
