Nicolaus Copernicus
Explanation:
In 1543, Nicolaus Copernicus detailed his radical theory of the Universe in which the Earth, along with the other planets, rotated around the Sun. His theory took more than a century to become widely accepted.
Answer:
0.33m/s²
Explanation:
Given parameters:
Initial velocity = 19.9m/s
Final velocity = 4.4m/s
Time = 47.6s
Unknown:
Acceleration = ?
Solution:
To solve this problem, we use the expression below:
Acceleration =
v is the final velocity
u is the initial velocity
t is the time taken
Acceleration =
Acceleration = -0.33m/s²
This is a deceleration
Answer:
true
Explanation:
Initially it requires more force to break the interlock between the irregularities of two surfaces. But once the block is in motion, it takes time to interlock between the irregularities of two surfaces. Also, the body gains the inertia of motion.
It's a Newton Meter Those two are multiplied to get a joule.
