Answer:
The current at time t = 4.00 s is 0.766 A.
Explanation:
Given that,
The quantity of charge through a conductor is modeled as :
We need to find the current (in A) at time t = 4.00 s. We know that the rate of change of electric charge is called electric current. It is given by :
At t = 4 s
So, the current at time t = 4.00 s is 0.766 A. Hence, this is the required solution.

Answer:
Its internal energy decreases by 40 J.
Explanation:
The energy supplied to the metal block causes the temperature of the block to rise. Therefore,
Now, we will use this value of mC to find out the energy change of block:
It shows that when the temperature of the metal block falls by 10°C,
<u>Its internal energy decreases by 40 J.</u>
Answer:
Explanation:
High concentrations of hydrogen ions yield a low pH (acidic substances), whereas low levels of hydrogen ions result in a high pH (basic substances). The overall concentration of hydrogen ions is inversely related to its pH and can be measured on the pH scale
Here is the answer to the given question above. <span>The majority of supercell thunderstorms move to the right of the mean layer wind. This tendency is the result of differences in barometric pressure that develop as vertical wind shear interacts with the storm's updraft. In response to this vertical wind shear, an area of low pressure develops in the upper region of the down shear (right) side of the storm's updraft. In contrast, a region of relatively higher pressure forms on the other side of the updraft in the up shear portion of the storm. The region of low pressure on the right side of the updraft creates a favorable environment for propagation of the storm and, in response, it moves to the right.</span>
