Answer:.
F = 3.0576sinθ
For any value of θ < 180
Explanation:
Generally, F = BILsinθ
Where,. F = magnetic force magnitude. B = magnetic Field magnitude.
L = length of wire. I = current
Therefore,
B = 0.260 T, L = 2.80 m
I = 4.20 A
: F = 0.260 × 4.20 × 2.80sinθ
∴ F = 3.0576sinθ
In the problem you are given what basically amounts to two sides (the legs) of a right triangle.
We are trying to find the hypotenuse of the triangle (which is the displacement).
Using the Pythagorean Theorem
a^2+b^2=c^2
we will plug in 26 and 6 for a and b, and then solve for c yielding an answer of 26.6833 yards.
To find the angle from the direction he ran forward, we can use a trigonometric function.
I will use the tangent function since we are given the adjacent and opposite sides (tanθ=(opp/.adj.)
tanθ=(6/26).
This yields a theta value of 12.9946 degrees (this is the angle from his initial running direction)
I'd say the answer to this on is d.Facts as they are using the temperatures in the graph and the temperatures are not just estimates
(a) The initial vertical velocity of the stone is 16.85 m/s and the initial horizontal velocity is 14.14 m/s.
(b) The final vertical velocity is 0 and the final horizontal velocity is 14.14 m/s.
<h3>
Initial vertical velocity</h3>
The initial vertical velocity of the stone is calculated as follows;
Vi = Vsinθ
Vi = 22 x sin(50)
Vi = 16.85 m/s
<h3>Initial horizontal velocity</h3>
Vxi = V cosθ
Vxi = 22 x cos(50)
Vxi = 14.14 m/s
<h3>Final vertical velocity of the stone</h3>
Vf = Vi - gt
where;
- Vf is the final vertical velocity = 0 at maximum height
<h3 /><h3>Final horizontal velocity of the stone</h3>
Vfx = Vxi = 14.14 m/s
Thus, the initial vertical velocity of the stone is 16.85 m/s and the initial horizontal velocity is 14.14 m/s.
The final vertical velocity is 0 and the final horizontal velocity is 14.14 m/s.
