Answer:
The current would be 0.12A
Explanation:
Well, the formula for electric current is
where i is current, q is charge and t is time. Then we have to calculate the charge. If we know that the charge of a proton is , then we calculate the charge of 1500 protons as it follows:
So the current for each square meter of Earth's surface is
Finally, knowing the surface of the Earth is 510065284702000 , we can calculate the total current
Answer: catching the ball is a better choice.
Explanation:
The collision of 2 objects involves involves large impact force since the force is inversely proportional to the time in which the momentum of the object changes.
Mathematically
If we catch the ball we increase the time in which the momentum of the ball is decreased thus the impact force that acts on us is lower as larger time is allowed for the ball to decrease it's momentum.
If we allow the ball to hit us the momentum of the ball changes in a short period of time thus applying a large impact force on our body thus increasing the chances of toppling.
Answer:
8ft/s
Explanation:
For computing the average velocity of the cork first we have to determine the frequency which is shown below:
= 4 Hz
Now the average velocity of the cork is
= 8ft/s
We simply applied the above formulas to determine the frequency and the velocity of the cork during this motion and the same is to be considered
