Answer:
The amount of gravitational potential energy an object has depends on its height and mass. The heavier the object and the higher it is above the ground, the more gravitational potential energy it holds. Gravitational potential energy increases as weight and height increases.
Explanation:
The correct answer is the last one:
A and C are different elements, while D is an isotope of C.
In fact, A and C are different elements, because they have a different number of protons in the nucleus (A has 3 protons, while C has 4 protons). Instead, D and C are the same element (they both have 4 protons in the nucleus), but they are different isotopes since they have a different number of neutrons (D has 4 neutrons while C has 3 neutrons)
The maximum height reached by the ball from the point of projection is 4.9 m.
<h3>
Maximum height of the ball</h3>
The maximum height reached by the ball from the point of projection can be calculated from time of motion.
h = vt + ¹/₂gt²
Assuming;
- v is the initial vertical velocity = 0
- g is acceleration due to gravity = 9.8 m/s²
- t is time of motion = 1 s
h = 0 + ¹/₂gt²
h = 0 + ¹/₂(9.8)(1)²
h = 4.9 m

because of the nagwtive charge will become positive
Answer:
Explanation:
We are given that
Final velocity, v=199 km/h=
1km/h=
Initial velocity, u=0
S=2000 m
We know that
Using the formula
Hence, the minimum acceleration necessary for the plane to take flight=
