Answer:
0.53 kg
Explanation:
Mass =
Force (also weight) = 8.0N
Acceleration = 15.0
=
= 0.53 kg ( to 2 decimal place )
Answer:
Velocity = v = 2.24m/s
Acceleration = a = 0.20m/s²
Explanation:
Please see attachment below.
Given
z=(−8 cosθ) and θ = 0.3t
z = -8Cos (0.3t)
V = dz/dt
a = v²/R.
Please see full solution below.
Answer:
Explanation:
There are two hypotheses she could test:
A cat's heart rate changes while it is napping.
A cat's heart rate does not change while it is napping.
The solar interior includes the core, radiative zone and convective zone. The photosphere is the visible surface of the Sun.
So the answers should be:
<u>A) Photosphere C) Core D) Radioactive zone </u>and<u> F) Convective zone.</u>
I hope this helps. Sorry if I made any mistakes. :)
