Answer:
Magnetic field will be equal to 
Explanation:
We have given velocity of proton 
Magnetic force experienced by proton 
Charge on proton 
Angle between field and velocity 
Force in magnetic field is equal to 
So 
So magnetic field will be equal to
First, find the components of
vector C (I don't know how you added the vector arrow but that's pretty cool).
Ax + Bx = Cx, Ay + By = Cy
5 + -3 = 2, 2 + -5 = -3
Vector C can be represented as 2x, -3y.
Next, using a trigonometric function tangent you may find the angle from the origin
= arctan(-3/2)
°
rad
Answer:
a) N = 7.90 10³ N, b) N = -1.04 10⁴ N
Explanation:
a) For this exercise we can use Newton's second law
N -W = m (-a)
The relationship is centripetal, the negative sign of the acceleration is because it points towards the center of the circle
a = v² / r
we substitute
N = mg -m v² /r
N = m (g - v² /r)
let's calculate
v = 8.7 m / s
N = 1240 (9.81 - 8.7²/22)
N = 7.90 10³ N
b) v = 20 m / s
N = 1240 (9.81 - 20²/22)
N = -1.04 10⁴ N
Answer:
318K
113°F
Explanation:
45°C = 45 + 273K = 318K
45°C = (45 × 9/5) + 32 = 81 + 32 = 113°F
Answer:
d) kinetic energy transformed to mechanical energy
Explanation:
Wind energy comes from its movement, so kinetic energy
Em = K = ½ m v²2
This energy spins the mill aspadle that this movement of the rotor within a magnetic field creates electricity in accordance with Faraday's law.
Consequently, from the above we should make a graph of the wind speed (kinetic energy) according to the electricity produced
The correct answer is d
