Igneous racks are known as primary
Answer:
θ = Cos⁻¹[A.B/|A||B|]
A. The angle between two nonzero vectors can be found by first dividing the dot product of the two vectors by the product of the two vectors' magnitudes. Then taking the inverse cosine of the result
Explanation:
We can use the formula of the dot product, in order to find the angle between two non-zero vectors. The formula of dot product between two non-zero vectors is written a follows:
A.B = |A||B| Cosθ
where,
A = 1st Non-Zero Vector
B = 2nd Non-Zero Vector
|A| = Magnitude of Vector A
|B| = Magnitude of Vector B
θ = Angle between vector A and B
Therefore,
Cos θ = A.B/|A||B|
<u>θ = Cos⁻¹[A.B/|A||B|]</u>
Hence, the correct answer will be:
<u>A. The angle between two nonzero vectors can be found by first dividing the dot product of the two vectors by the product of the two vectors' magnitudes. Then taking the inverse cosine of the result</u>
1. F=ma
Here we have an acceleration = 2.3 and a mass = 14
So...
F = (14)(2.3)
F = 32.2 N
2. F = ma
Here we have an acceleration = 6.4 and a force = 1473
Rearrange your equation for m
F/a = m
1473 / 6.4 = m
m = 230.16 kg
3. F = ma
Here we have a force = 94 and a mass = 45
Rearrange for acceleration
F/m = a
94 / 45 = a
a = 2.09 m/s^2
Answer:
150A
Explanation:
Given parameters:
Potential difference = 120V
Resistance = 0.8Ω
Unknown:
Current = ?
Solution:
From ohm's law;
I =
I is the current
V is the voltage
R is the resistance
Now insert the parameters and solve;
I = = 150A
Geosphere, hydrosphere, atmosphere, and biosphere.
Therefore, the correct answer is D.
