Answer:
option B
Explanation:
Current unit is ampere (A)
Ampere will be equivalent to = ?
we know,
Current can be define as the charge per unit time
unit of charge(Q) is coulomb which is equal to C.
unit of time(t) is equal to 's'.
now,
unit of I = C/s
ampere(A) is equivalent to C/s
The correct answer is option B
Answer:
Explanation:
Terry can ride at a speed of
V = 30 miles in 2hours
Speed = distance / time
V = 30 /2
V = 15 mile/hour
So, we want to know the distance traveled in 1.7hours
Then,
Speed = distane / time
Distance = speed × time
Distance =15 × 1.7
Distance = 25.5 miles
So, the distance traveled in 1.7hours is 25.5 miles
As the water plunges, its velocity increases. Its potential energy<span> becomes kinetic</span>energy<span>. The law of conservation of </span>energy<span> states that when one form of </span>energy<span> is</span>transformed<span> to another, no </span>energy<span> is destroyed in the process. ... So the total amount of </span>energy<span> is the same before and after any </span>transformation<span>.

It would be 12W because: 6v is half of 12v so half of 24w would be 12w
Answer:
20 cm
Explanation:
Given that a ball is released from a vertical height of 20 cm. It rolls down a "perfectly frictionless" ramp and up a similar ramp. What vertical height on the second ramp will the ball reach before it starts to roll back down?
Since it is perfectly frictionless, the Kinetic energy in which the ball is rolling will be equal to the potential energy at the edge of the ramp.
Therefore, the ball will reach 20 cm before it starts to roll back down.
