Answer:
denisity = 52.33 g/c
Explanation:
Density:
We have that m = 785 and that v = 15 c.
d = 52.33
I am not suer but i thx it is...
Answer:
True
Explanation:
The reason is because factories or other places like a lab have to test if its safe and a good product to sell
The letter refers to the shape of the orbital. The letters go in the order s, p, d, f, g, h, i, j, etc. The letters s, p, d, and f were assigned for historical reasons that need not concern us. All we have to do is remember the shapes that correspond to each letter.
hope this helps!
Answer:
θ = 73.6º
Explanation:
To solve this exercise, let's use Newton's second law. Let's set a reference system where the x-axis is parallel to the inclined plane
with trigonometry we can find the components of the weight
sin θ = Wₓ / W
cos θ= W_y / W
Wₓ = W sin θ
W_ = W cos θ
Y axis
N - W_y = 0
N = W_y
X axis
Wₓ - fr = m a
mg cos θ - fr = m a
indicate that friction is zero, fr = 0
cos θ = a / g
θ = cos⁻¹
let's calculate
θ = cos⁻¹
θ = 73.6º
