In a game of pool the cue ball is rolling at 2.00 m / s in a direction 30.0° north of east when it collides with the eight ball

victus00 [196]

Answer:

$v_{f1}=1.758m/s$

Explanation:

The collision is elastic so we can use the conservation of momentum

$P_i=P_f$

$m_1*v_1+m_2*v_2=m_1*v_{f1}+m_2*v_{f2}$

Describe the motion in axis x'

$170g*2.0m/s*cos(30)+156g*0m/s=170*cos(10)*v_{f1}+156g*0m/s$

$294.44 g*m/s=167.41g*v_{f1}$

$v_{f1}=1.758m/s$

Describe the motion in axis y'

$170g*2.0m/s*sin(30)=170g*1.75m/s*sin(10)+156*v_{f2}$

$v_{f2}=1.55m/s$

The potential (relative to infinity) at the midpoint of a square is 3.0 V when a point charge of +Q is located at one of the cor

Sveta_85 [38]

Answer:

d) 12 V

Explanation:

Due to the symmetry of the problem, the potential (relative to infinity) at the midpoint of the square, is the same for all charges, provided they be of the same magnitude and sign, and be located at one of the corners of the square.

We can apply the superposition principle (as the potential is linear with the charge) and calculating the total potential due to the 4 charges, just adding the potential due to any of them:

V = V(Q₁) + V(Q₂) +V(Q₃) + V(Q₄) = 4* 3.0 V = 12. 0 V

densk [106]

Answer:

Minutes can provide us the continuous data as we can have the values between the two minutes, in fraction. So if we consider minutes there will be a complete continuous data for the analysis. However the number of cars, trucks, pedestrians, bicyclists, food trucks etc will be in integers as they can not be described in terms of fractions. So for continuous data option (E) is correct.

The number of minutes for a car to get from the intersection to the administration building.
