B. Elastic potential to kinetic energy
The elastic potential energy in the slingshot will be transferred to the stone as kinetic energy as the stone is launched.
Pressure = Force/ Area = 3000/2 = 1500 pascal.
Answer:
<h2>400 J</h2>
Explanation:
The work done by an object can be found by using the formula
workdone = force × distance
From the question we have
workdone = 50 × 8
We have the final answer as
<h3>400 J</h3>
Hope this helps you
Answer:
Protons, Neutrons, and electrons
Explanation:
Protons, electrons and neutrons are subatomic particles
Protons is positively charged particle yan
The electrons a negatively cacricated particle
Neutrons are particles that have no charge
Explanation:
Using kinematics,
t = 4s
u = 0m/s
a = 9.8m/s^2
Therefore v = u + at = 0 + (4)(9.8) = 39.2m/s.
