Answer:
v = -0.45 m/s
Explanation:
Assuming the canoe was initially at rest with momentum L = 0
and that the dog's velocity is in the positive direction
conservation of momentum
0 = 15(1.2) + 40v
v = -0.45 m/s
Explanation:
Stern et al. (1999) and Stern (2000), define this variable as those general visions about the world, reflected in the beliefs that people express about their relationship with the environment and nature.हेलो फ्रेंड्स मारो किसी को इनबॉक्स कैसे करें
Answer:
Aristotle
Explanation:
Aristotle would describe an airplane as "Earthen metal infused with Air and propelled by elemental Fire".
Their presence spread in to the Renaissance from the Antiquity and Early medieval Ages, and was not consistently displaced until the Inquisition and philosophies such as classical physics.Aristotle's views on biblical theory were influenced by physical science. Many of the zoological findings of Aristotle found in his physiology, such as on the octopus ' hectocotyl (reproductive) head, remained incredible until the 19th century.

Answer</h2>
Causality means reason behind the process
<h2>
Explanation</h2>
In the scientific inquiries, scientists perform different activities with the help of previous knowledge and scientific ways to renew the knowledge or discover the new ideas. It is a common belief that in every process that is happening in nature have many functions and reasons behind it. Scientists are always in the struggle to find these reasons and their importance regarding their happenings. When the scientists are in hurry to know about the causality, it means they are helping the scientific knowledge with the discovery of new reasons for happens.
m = mass of the penny
r = distance of the penny from the center of the turntable or axis of rotation
w = angular speed of rotation of turntable
F = centripetal force experienced by the penny
centripetal force "F" experienced by the penny of "m" at distance "r" from axis of rotation is given as
F = m r w²
in the above equation , mass of penny "m" and angular speed "w" of the turntable is same at all places. hence the centripetal force directly depends on the radius .
hence greater the distance from center , greater will be the centripetal force to remain in place.
So at the edge of the turntable , the penny experiences largest centripetal force to remain in place.
