Issac newton how did he shape the new worldview?
gulaghasi [49]

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.

When is your kinetic energy the least when swinging on a park swing?
Afina-wow [57]

Answer:

An active pendulum has the most kinetic energy at the lowest point of its swing when the weight is moving fastest.

Explanation:

SO YOU HAVE THE LEAST KINETIC ENERGY AT THE HIGHEST POINT OF THE SWING WHEN IT'S NOT ACTIVE

José and Laurel measured the length of a stick's shadow during the day. Without knowing the length of the stick, which of their
skelet666 [1.2K]

Answer:

Option B.

Explanation:

Assuming the stick is in vertical position, its shadow depends on two factors: its length and the angle between the sun rays and the stick. When the angle is bigger, the lenght of the shadow increases, and vice versa. So, when the sun rays are parallel to the stick, the shadow may be small. Since they are nearly perpendicular to the Earth's surface at 12 o'clock, the shadow of the stick at that time should be minimal. It means that the measured shadow of 75 cm at 12:30 p.m. is almost impossible (Option B).

denis23 [38]
To reach a vertical height of 13.8 ft against gravity, which has an acceleration of 32 ft/s^2, the required vertical speed can be calculated from the equation:
vi^2 - vf^2 = 2*g*h
Given that it has vf = 0 (it is not moving vertically at its maximum height), g = 32, and h = 13.8, we can solve for vi:
vi^2 = 29.72 ft/s
This is only its vertical speed, so this is equivalent to its original speed multiplied by the sine of the angle:
29.72 ft/s = (v_original)*(sin 42.2<span>°</span>)
v_original = 44.24 ft/s
Converting to m/s, this can be divided by 3.28 to get 13.49 m/s.
