Answer:
so am i ._. 15 not 1 ofc lol
Explanation:
The second statement is correct : Gravity is a force that pulls objects towards Earth's centre.
Answer:
The magnitude of the electrostatic force is 120.85 N
Explanation:
We can use Coulomb's law to find the electrostatic force between the down quarks.
In scalar form, Coulomb's law states that for charges
and
separated by a distance d, the magnitude of the electrostatic force F between them is:

where
is Coulomb's constant.
Taking the values:


and knowing the value of the Coulomb's constant:

Taking all this in consideration:


<span>You will exert less force the more the lever is longer. So, you need to place your hands as high as possible with the hammers handle.</span>
