Answer:An object with mass in a gravitational field experiences a force called weight. This weight on the moon is about 1/6 but the mass of that object remains the same due to the moon's gravitational field which is less than the earth.
Explanation:There are factors that affect the gravitational potential and kinetic energy . They are:
1. The height of the object in the moon
2.The mass of the object
3. The strength of the gravitational field
4. The change in position of the object.
Answer:
A) Bohr’s work with atomic spectra led him to say that the electrons were limited to existing in certain energy levels, like standing on the rungs of a ladder.
Explanation:
The change to the atomic model that helped solve the problem seen in Rutherford's model was the discovery of the strong nuclear force.
Rutherford's model required that the electrons be in motion. Positive and negative charges attract each other, so stationary electrons would fall into the positive nucleus. However, Rutherford's model failed to explain why electrons were not pulled into the atomic nucleus by this attraction. The change to the atomic model that helped solve this problem was the discovery of the strong nuclear force, which is much stronger than electrostatic interactions and holds the protons and neutrons together in the nucleus.

Critical thinking requires the ability to gather information, analyze and evaluate it to form a judgment. It requires reflective, clear reasoning and emphasizes deep analysis and interpretation. Enhancing these skills can occur through various academic avenues, including the study of philosophy and legal systems.
Critical thinking requires that an individual is able to identify and solve problems by gathering information about a topic and then analyzing and evaluating evidence to form a judgment. It involves a set of skills, habits, and attitudes that promote reflective, clear reasoning. It encourages an approach that goes beyond the surface of words and images to deeply analyze, interpret, and evaluate aspects of a given topic.
Studying philosophy, courts, and judiciary systems, or examining critical thinking questions in various academic settings can actually enhance your ability to think critically. It encourages learners to demonstrate their understanding by applying what they have learned in different contexts using reasoning and outside-the-box thinking. It pushes the students to places they wouldn't have thought of going to themselves.
Every functioning government must have a functioning judicial system. Critical thinking skills are utilized in careers within legal systems and beyond, making them highly valued skills in the job market.

28.45 m/s
34.91 m/s
21.29 m/s
The initial velocity is 12.34 m/s
Explanation:
The vertical component of the initial velocity determines the maximum height.
The formula to apply is : v²=u²+2as , where
v=y-component, final velocity = 0 m/s
u= y-component of the initial velocity = ?
s= distance traveled = 2.3 m
a=acceleration due to gravity = -9.81 m/s²
Using the values in the equation
v²=u²+2as
0²=u²+2×2.3×-9.81
0=u²-45.126
45.126=u²
√45.126= u
6.7175 m/s
The vertical component of velocity is given by;
velocity*sin(angle with horizontal)
velocity=6.7175 / sin 33°
=12.338 m/s
=12.34 m/s
