According to Ohm's law for a portion of the circuit we have:
U=RI=>I=U/R=24/3=8 A
The correct answer is B
Answer: The correct answer for the fill in the blank is - medium of exchange.
Explanation-
When we use paper money to pay for food, the money is a medium of exchange as we are exchanging our money with their food. So, it plays a role of medium of exchange in purchasing our food.
On the other hand, unit of account is also a feature of money but it only indicates the price of food at which we are purchasing it. Store of value is used when we store our money as a wealth, then it becomes store of value .
Hence, medium of exchange is the correct answer.
Answer:
2450 J
Explanation:
Given that,
A 50Kg girl jumps off a 5-meter-high diving board.
We need to find the kinetic energy of the girl before she hits the water. At this point the kinetic energy becomes equal to the potential energy such that,
So, her kinetic energy right before she hits the water is equal to 2450 J.
Positive acceleration occurs when an object speeds up.
Explanation:
Acceleration is the rate of change in velocity per unit time:
where 
is the change in velocity while 
is the time interval. From the formula, we can understand that when is positive, so when the object is speeding up, the acceleration is positive; on the contrary, when is negative (so, when the object is slowing down), the acceleration is negative.
