Answer:
3.91
Explanation:
Given that
Final reading of the voltmeter, V2 = 45 v
Initial reading of the voltmeter, V1 = 11.5 v
The dielectric constant k, of a material is usually given as
k = V2/V1
k = 45 / 11.5
k = 3.91
Therefore, the dielectric constant of the material as we've calculated above is sure to be 3.91.

Acceleration of an object is depended upon the net force acting open the object and the mass of the object
Since the collision is inelastic, both vehicle will move with a common velocity of 2.5 m/s in south east direction after collision.
<h3>
Conservation of Linear Momentum</h3>
It states that, the sum of the momentum before collision is equal to the sum of the momentum after collision.
Given that a 7500 kg truck traveling at 5.0 m/s east collides with a 1500 kg car moving at 20 m/s in a direction 30° south of west. After collision, the two vehicles remain tangled together.
The given parameters are;
The formula to find the speed will be
M1U1 - M2U2 = (M1 + M2)V
7500 × 5 - 1500 × 10 = (7500 + 1500)V
37500 - 15000 = 9000V
22500 = 9000V
V = 22500/9000
V = 2.5 m/s
Therefore, the common speed will be 2.5 m/s and the direction of the car will be toward the south east.
