Answer:
I THINK option A is correct
Explanation:
because the electrostatic force is directly proportional to product of charges
now if the force between two electron is F charge on electron is same so their product is positive now the charge on proton is +ve and on electron is -ve so their product is -F
Answer:
The water must flow with the velocity of 141.4m/s
Explanation:
The kinetic energy is energy due to the motion of a body
In this Case the kinetic energy of the turbine is given as
KE=1/2mv²
Where KE= kinetic energy
m= mass of water
v= velocity of the water
Data given
KE=10000j
m=1000g------kg =1000/1000= 1kg
v=?
Substituting our data into the expression we have
10,000=1/2(1*v²)
10,000=v²/2
Solving for v we have
v²=20,000
v=√20,000
v=141.4m/s
Answer: in the Newton concluded that objects fall because they are pulled by Earth's gravity. Einstein's interpretation was that these objects do not fall.
Explanation: These objects and Earth just freely move in a curved spacetime and this curvature is induced by mass and energy of these objects. - I HOPE THAT HELPED!!
