Answer:
In the film Ice word Revenge, vehicle 2 did not fall of the cliff because,  but in Claire's test, vehicle 2 off the cliff because
 but in Claire's test, vehicle 2 off the cliff because 
Explanation:
In Claire's test, the weight of vehicle 1 is either equal to or greater than the weight of vehicle 2, so it was sufficient to push it down the cliff.  In the film Ice word revenge, the weight of vehicle 1 is less than the weight of vehicle 2, it is not sufficient to make it fall off the cliff ( Note: Looking exactly the same in the movie, as Claire claimed, does not mean they have the same mass). Therefore if Claire wants a collision that will not make the vehicle 2 fall off the cliff, he should collide it with a vehicle of lesser mass/weight.
 
        
             
        
        
        
With the help of a transformer  input voltage is transformed into an output voltage
<h3>What is induced voltage?</h3>
Electromagnetic induction is what causes the induced voltage. Electromagnetic induction is the process of generating emf (induced voltage) by subjecting a conductor to a magnetic field.
In this case, a magnet is pushed in and out of a wire coil attached to a high-resistance voltmeter.
Typically, a transformer's primary winding is attached to the input voltage source and changes electrical power into a magnetic field. 
The secondary winding's role is to turn this alternating magnetic field into electricity, generating the necessary output voltage.
Hence with the help of a transformer input voltage is transformed into an output voltage.

You have to use the specific heat equation. 
Q = cmΔT where Q is the energy, c is specific heat, m is mass, and ΔT is change in temp.
So we can substitute our variables into the equation.
30000J = (390g)(3.9J*g/C)ΔT
Solving for ΔT, we get:
30000J/[(390g)*(3.9J*g/C) = ΔT
ΔT = 19.72386588C
I'm assuming the temperature is C, since it was not specified.
Hope this helps!
        
             
        
        
        
Answer:
a) ΔV = 25.59 V, b)  ΔV = 25.59 V,  c)  v = 7 10⁴ m / s,  v/c= 2.33 10⁻⁴ ,
v/c% = 2.33 10⁻²
Explanation:
a) The speed they ask for electrons is much lower than the speed of light, so we don't need relativistic corrections, let's use the concepts of energy
starting point. Where the electrons come out
           Em₀ = U = e DV
final point. Where they hit the target
           Em_f = K = ½ m v2
 energy is conserved
           Em₀ = Em_f
          e ΔV = ½ m v²
          ΔV =  mv²/e     (1)
 mv²/e     (1)
If the speed of light is c and this is 100% then 1% is
          v = 1% c = c / 100
          v = 3 10⁸/100 = 3 10⁶6 m/ s
let's calculate
          ΔV =  
          ΔV = 25.59 V
 b) Ask for the potential difference for protons with the same kinetic energy as electrons
               
               K_p = ½ m v_e²
               K_p =  9.1 10⁻³¹ (3 10⁶)²
  9.1 10⁻³¹ (3 10⁶)²
               K_p = 40.95 10⁻¹⁹ J
we substitute in equation 1
               ΔV = Kp / M
               ΔV = 40.95 10⁻¹⁹ / 1.6 10⁻¹⁹
               ΔV = 25.59 V
notice that these protons go much slower than electrons because their mass is greater
c) The speed of the protons is
              e ΔV = ½ M v²
              v² = 2 e ΔV / M
              v² =  
               v² = 49,035 10⁸
                v = 7 10⁴ m / s
Relation
         v/c = 
         v/c= 2.33 10⁻⁴

First, let's convert that speed into m/s.
150 km/h * 1000 m/km / 3600 s/h = 41.667 m/s
Now let's see how much time gravity has to work on the ball. Divide the distance by the speed.
18 m / 41.667 m/s = 0.431996544 s
Now multiply that time by the gravitational acceleration to see what the vertical component to the ball's speed that gravity adds.
0.431996544 s * 9.8 m/s^2 = 4.233566131 m/s
Use the pythagorean theorem to get the new velocity of the ball.
sqrt(41.667^2 + 4.234^2) = 41.882 m/s
Finally, let's see what the difference is
(41.882 - 41.667)/41.667 = 0.005159959 = 0.5159959%
Rounding to 2 figures, gives 0.52%</span>
