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 
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.

Answer:
The voltage will quadruple
Explanation:
The power dissipated in a circuit is given by

where
V is the voltage
R is the resistance
In this problem, the voltage across the circuit is doubled:
V' = 2V
So the new power dissipated is

so, the power dissipated will quadruple.
Answer:
In waves distance is measured by wave length and time is measured by frequency or period.
velocity ratio=wave length multiply by frequency.
HENCE, if the same wave travels for 2 econds its frequency will be 2Hz.
