The correct answer is Van de Graaff generator. A large electrostatic generator is commonly called a Van de Graaff generator. This large generator is a device for the production of high voltage by means of endless belt collecting of electrostatic charge.
Answer:water is more dense
Explanation:
Answer:
Explanation:
The kinematic equation
gives the final velocity of the object given the initial velocity , the acceleration , and the distance traveled .
For our case, the object is dropped; therefore,
I.e. the initial velocity is zero. The acceleration due to gravity is
,
and the distance traveled is .
Putting the values into the equation we get:
The final velocity of the object is 44.27 m/s.
When a vehicle changes direction, its velocity also changes since velocity comprises both speed and direction.
<h3>How do you calculate final velocity?</h3>
V f is equal to V i plus At. The final velocity of an item can be calculated for a given beginning velocity by multiplying the acceleration brought on by a force by the time the force is applied and then adding the result to the initial velocity.
<h3>What is the collision formula?</h3>
An elastic collision is one in which the momentum, p, and the kinetic energy, KE, are both conserved. In other words, po = pf and KE0 = KEf are the results. We will write 1/2 m1 when we remember that KE = 1/2 mv2 (v1i) 2 + 1/2 m2(vi) (vi) 2 is equal to half of m(v1f) and m(v2f).
