Answer:
A. They can provide an accurate picture of someone’s personality.
C. They can be used to target employee training.
E. They may lead to lower turnover rates.
Explanation:
Answer:
Gravity
Explanation:
Mass and motion are not forces and newton is unit of force. Gravity is defined as force of attraction or repulsion between two bodies and hence is the answer.
Answer
Given,
inner radius, r = 0.7 m
outer radius, R = 1.30 m
Number of turns, N = 8long 60
Current, I = 13 kA
a) Magnetic field inside the toroid along the inner radius
B = 3.194 T
b) Magnetic field inside the toroid along the outer radius
B = 1.72 T
Answer:
a) 45 s , b) vₐ = 90 m / s, v_b = 162 m / s, c) x_b = 3.328 10⁴ m
Explanation:
We can solve this exercise using the kinematic relations
Vehicle A
xₐ = v₀ₐ t + ½ aₐ t²
vehicle B
starts two seconds later
x_b = v_{ob} (t-2) + ½ a_b (t-2) ²
as cars start from rest their initial velocities are zero
at the point where they meet, the position must be the same for both vehicles
xa = 0 + ½ aₐ t²
xb = 0 + ½ a_b (t-2) ²
½ aₐ t² = ½ a_b (t-2) ²
t = (t-2)
t (1 - \sqrt{ \frac{a_a}{a_b} }) = 2
t (1 - ⅔, ) = 2
t = 2 / 0.4444
t = 45 s
b)
the speed of each car
vₐ = voa + aa t
vₐ = 0 + 2 45
vₐ = 90 m / s
v_b = 3.6 45
v_b = 162 m / s
c) xb = 0 + ½ ab (t-2) ²
x_b = ½ 3.6 (45-2) ²
x_b = 3.328 10⁴ m
