i think centripetal Force
It would need to be over 20 because if the load of the Pulley E is 20 and the effort is 20, then they will be equal and the Pulley would not move, so your answer is at least 20
Answer:
C. A baseball bat strikes a baseball.
Explanation:
Newton's second law of motion states that acceleration happens when force is applied on the mass.
<em>A baseball bat strikes a baseball is the best example of Newton's second law of motion because acceleration of the baseball is directly proportional to the force by which baseball bat hit it.</em>
Hence, the correct option is 'C. A baseball bat strikes a baseball.'
Answer:
8.87 gallons of kerosene
Explanation:
Step 1: Given and required data
- Energy to travel by plane per passenger trip: 1,260 MJ/passenger trip
- Energy per gallon of kerosene: 142 MJ/gal
Step 2: Calculate how many gallons of kerosene it takes to make the trip by plane
We can calculate the amount of kerosene required by combining the factor provided in Step 1.
1 gal/142 MJ × 1,260 MJ/passenger trip = 8.87 gal/passenger trip
8.87 gallons of kerosene are required to make the trip by plane.
Answer:
it is zero because the electric gap is zero within the material
Explanation:
In a metal you have many free electrons, and fixed charges formed by nuclei and electrons that are not free; therefore the charge carriers are the free electrons, these have the same negative charge and due to the lectrostatic force they repel each other as far as possible without leaving the material, this implies that at two points there must be the same potential because otherwise there would be a net Caesarian force accumulating charge in a part that would be eliminated by the Coulomb force.
With this we can review the statements the strap is: it is zero because the electric gap is zero within the material
