Answer:
Natural science is concerned with the description, prediction, and understanding of natural phenomena based on empirical evidence from observation and experimentation. It can be divided into two main branches: life science (or biological science) and physical science.
Explanation:
Answer:
its an antique physics apparatus for demonstrating acoustic standing waves in a tube.
Answer:
This is Newton's second law.
<u>Newton's second law text:</u>
(If a resultant force acts on a body, then an acceleration will give it an acceleration, the magnitude of which is directly proportional to the amount of the net force, and a direction is in the direction of the net force itself)
F=ma
net force = mass x acceleration
I hope I helped you^_^
Answer:
a= 8.74 m/s²
Explanation:
Given that
m = 21 kg
θ = 13◦
F= 210 N
g= 9.8 m/s²
The force due to gravity
F₁= m g sinθ
F₁=12 x 9.8 x sin 13◦
F₁=26.45 N
Lets take acceleration is a m/s²
Form Newtons second law
F - F₁ = m a
210 - 26.45 = 21 x a
a= 8.74 m/s²
Answer:
it does show the objects position
