Accordingly Newton's findings, astronomy and physics have industrialized
hugely over the period. Scientists now recognize that every object in the
world has a force that draws each other and the power of the force hinge on the
mass of the object. Also, Newton's Laws of Motion offer individuals a
better understanding of what is likely concerning movement. This is very helpful,
particularly in mechanics and space travel. Generally, Newton had a
huge and permanent impact on science.
Answer:
The moon is 400x smaller but it's also 400x closer so it looks the same size even though it's not
Explanation:
Answer:
The correct answer is: justice
Explanation:
The Belmont Report refers to a report that was published 25 year ago, focusing on the ethical treatment and protection of participants in medical and behavioral research. This report centers around 3 principles:
1. Beneficence- striving to maximize benefits for participants of the research study and minimizing any harms/ risks that might occur.
2. Justice- The fair selection of potential participants for a study. This ensures equitable and fair distribution of risks/ benefits to all potential participants of a research study. Subjects of a study must not be chosen merely out of convenience or easy access. The inclusion/ exclusion criteria should be chosen according to the nature of the study and steps/ treatments that it will involve.
3. Respect for persons- Each participant of a research study should be able to provide informed consent prior to their participation, protected from controllable harm and treated with respect.
Therefore, moral requirement that there be fair outcomes in the selection of research subjects, expresses the principle of justice.
corrected question:A golf ball is hit with an angle of elevation 60∘ and speed 25ft/s. Find the horizontal and vertical components of the velocity vector. (Your answer must be exact)
Answer:
Horizontal component=12.5ft/s, vertical component=21.65ft/s
Explanation:
The bal moves with a velocity of 25ft/s at an angle of 60°.
The horizontal component(Vx) and vertical component(Vy) of velocity can be calculated as follows;
Vx=Vcosθ
Vy=Vsinθ
Vx=25cos60°
=12.5ft/s
Vy=25*sin60°
Vy=21.65ft/s
Answer:
Tangential speed, v = 314.15 m/s
Explanation:
It is given that,
Mass of the object, m = 15 kg
It is moving in a circle of radius, r = 10 m
Time period, t = 0.2 seconds
We need to find the tangential velocity of the object. It is given by :
Where
v = tangential speed
v = 314.15 m/s
So, the tangential speed of the object is 314.15 m/s. Hence, this is the required solution.
