Answer:
The angular speed of rolling ball is 3.23 rad/sec.
Explanation:
Given that,
Radius = 1.95 cm
Speed = 6.30 cm/s
Suppose, we need to find the angular speed of rolling ball
We need to calculate the angular velocity
Using formula of angular velocity
Where, r = radius
= angular velocity
Put the value into the formula
Hence, The angular speed of rolling ball is 3.23 rad/sec.
Answer:
Sir Isaac Newton
Explanation:
The laws according to which bodies move and how one body attracts another body were developed by Newton. The three laws of motion and the law of universal gravitation were developed by Newton.
In the seventeenth century almost all the refracting telescopes exhibited color distortion. Newton believed that white light had a spectrum which was the reason for this distortion. The lens of a refracting telescope used to act like a prism which caused the dispersion of light proving Newton's hypothesis.

First, split the velocity into horizontal and vertical components.
h = 21 cos(47°) = 21 * 0.744270977 = 15.62969052 m/s
v = 21 sin(47°) = 21 * 0.731353702 = 15.35842773 m/s
Now determine how many seconds the ball had to travel to reach 57 meters.
T = 57 m / 15.62969052 m/s = 3.647 s
height of the ball at time T is
d = vT - 0.5AT^2
where
v = initial velocity
T = Time
A = acceleration due to gravity (9.8m/s^2)
Plug in the known values
d = (15.35842773 m/s)(3.647 s) - 0.5 9.8 m/s^2 (3.647 s)^2
d = 56.01219 m - 4.9 m/s^2 (13.30061s^2)
d = 56.01219 m - 65.17298 m
d = -9.1608 m
So the ball fell a total of 9.16 meters, which means that the building was 9.16 meters tall.</span>
Many people are in favor of the dam. Hydroelectric power is not as polluting
as other forms of electrical generation. The country is growing quickly, and
its economy is growing. The country must be able to produce more electricity
to meet everyone's needs. However, those opposed say the dams will force
many out of their homes. It will destroy an important wilderness area, and may
damage ecosystems - especially river or fjord ecosystems in Patagonia, since
silt won't be carried down rivers. Many also say that the project helps the
copper mining industry, and they believe that this project will benefit
businesses, not the people of Chile
