Answer:
The maximum height reached by the ball is 20 meters
Explanation:
Given that,
Height, h = 10 m
Potential energy at the height of 10 m,
The ball is moving upward with a kinetic energy of 50 Joules
Let h is the maximum height reached by the ball. At a height of 10 meters above the ground, the energy is given by :
mg = 5 N
At this point, total energy will be 100 J. We know that the velocity is zero at maximum height. So, the ball possess only potential energy. it is given by :
h = 20 meters
So, the maximum height reached by the ball is 20 meters. Hence, this is the required solution.
Answer:
30N is the correct answer
Answer:
i think ww
Explanation:
i think we need to calculate net force which is:
net force=m.a
..nf=1000kg×30m/s
therefore net force will be the answer you get whwn you multiply those two
Answer:
Uh, I could be wrong but doesn’t it mean that the wave and particle are reacting together to make light? I think it’s something like that... I hope this helps!
Answer:
FC vector representation
Magnitude of FC
Vector direction FC
degrees: angle that forms FC with the horizontal
Explanation:
Conceptual analysis
Because the particle C is close to two other electrically charged particles, it will experience two electrical forces and the solution of the problem is of a vector nature.
The directions of the individual forces exerted by qA and qB on qC are shown in the attached figure; The force (FAC) of qA over qC is repulsive because they have equal signs and the force (FBC) of qB over qC is attractive because they have opposite signs.
The FAC force is up in the positive direction and the FBC force forms an α angle with respect to the x axis.
degrees
To calculate the magnitudes of the forces we apply Coulomb's law:
Equation (1): Magnitude of the electric force of the charge qA over the charge qC
Equation (2)
: Magnitude of the electric force of the charge qB over the charge qC
