Electrons have electrical magnetic fields that require them to have energy that is too intense for quarks
This is the reason why dimensional analysis is very important. It is a technique used that only involves operations with units. You disregard the quantities first. The concept is to make sure that the final answer of your calculations must be consistent of what is asked. Similar units are cancelled when they appear both on the numerator and denominator side. If the mathematicians used this, they could've prevented the crash from happening. What good would the calculations bring if you are not consistent with the units?
Answer:
B. The force would be the same in both cases.
Explanation:
According to Newton's 3rd law where impulse was equated to the momentum formula.
F × t = M × V
where,
Force = F
V = velocity
Since, Impulse is force multiplied by time, whereas the time of contact is the same for both, therefore the impulse is the same in magnitude for the two trucks.
Case 1: Hitting the other car
Case 2: Hitting the brick wall
In Case 1, both the cars are identical and have same velocity whereas in the Case 2, the wall is stationary.
The case of hitting the brick wall have the same impact force as hitting the other car, because they have the same change in momentum.
Therefore, The force would be the same in both cases.
Answer: a. Regularly, you rub your hands for warmth.
b. Some examples are friction from electricity going through a wire or friction from rubbing your hand together.
c. Without friction, we would fall every time we walked. Because there is friction, we can walk normally. Another example is a ball moving across the field. Without friction, the ball would not slow down.
Explanation:
Overall, friction is important to us because we depend on it.
