The formula of the kinetic energy is:
where m is a mass of the object, v is speed of the object at the moment of time. So we have:
The answer is
2000 Joules.
Answer:
I believe it's A.)
Explanation:
Although light comes into our atmosphere through refraction, it reaches our eyes only through reflection from objects. So when light rays reflect off an object and enter the eyes through the cornea you can then see that object.
Hope this helps you out : )
Answer:
When waves overlap in-phase (crest meets crest or trough meets trough) the waves energy is additive and the amplitude increases.
Explanation:
When waves overlap out-of-phase (crest meets trough) the waves cancel and the amplitude (energy) decreases. When two interfering waves cancel each other out.
Human dignity and worth and social justice are TWO OF THE BASIC VALUES OF THE CODE OF ETHICS FOR SOCIAL WORK.
Social workers are those professionals, who promote social change by helping to relieve hardship and suffering. Social work is committed to five basic values, which are:
1. Human dignity and worth
2. Social justice
3. Service to humanity
4. Integrity
5. Competence.
The human dignity and self worth value holds that all human beings have intrinsic value, right to well being, right to self fulfillment and control over their own lives.
The social justice value states that there should be fair and equitable distribution of resources to meet basic human needs and all citizens should have access to public resources in order to achieve full potential.
Answer:
A factor of 2*4 = 8
Explanation:
F_g = (G*m1*m2)/r^2
where m1 and m2 are the two masses, G is Newton's gravitational constant, and r is the distance between the center of mass of the two objects.
So, if you double m1 and quadruple m2:
m1' = 2*m1
m2' = 4*m2
Then F_g' = (G*m1'*m2')/r^2 = (G*2*m1*4*m2)/r^2 = 8*(G*m1*m2)/r^2 = 8*F_g
