Given a 10-V power supply, would a 20-ohm resistor and a 5-ohm resistor need to be arranged in parallel or in series to generate a current of 2.5 A? How much current would move through each resistor? In 3-4 sentences, answer each question and explain your answers

The arrangement of the resistors to generate a current of 2.5 A is  a parallel arrangement and the current flowing the first resistor is     while the current flowing through the second resistor is  

Explanation:

From the question we are told that

   The voltage is  

   The first resistor is  

    The second resistor is  

    The current is  

Generally the resistance of the circuit is mathematically evaluated as

=>  

=>  

When the given resistors are connected in series the resistance is  

=>      

=>  

Generally when the resistors are connected in parallel the resistance is  

=>        

=>    

The current flowing through resistor 1 is mathematically represented as

=>    

=>    

The current flowing through resistor 1 is mathematically represented as

=>    

=>  

The arrangement of the resistors to generate a current of 2.5 A is  a parallel arrangement and the current flowing the first resistor is     while the current flowing through the second resistor is  

b.a device that inputs heat into a cool object

initial speed when it is dropped is 150 ft/s

now at the same moment the acceleration due to gravity is perpendicular to its velocity

so as we know that

now we have centripetal acceleration a = 32 ft/s^2 as its perpendicular to velocity

while tangential acceleration at the same moment will be zero

so

now radius of curvature is given as

so the radius of curvature just after it is dropped is 703.125 ft
