Answer:
Answer b)
Explanation:
The correct answer is that analog technology stores information as sound-waves, while digital technology stores it as strings of ones and zeroes. So pick answer b)
Answer:
The magnitude of the electric force on a protein with this charge is 
Explanation:
Given that,
Electric field = 1500 N/C
Charge = 30 e
We need to calculate the magnitude of the electric force on a protein with this charge
Using formula of electrostatic force

Where, F = force
E = electric field
q = charge
Put the value into the formula


Hence, The magnitude of the electric force on a protein with this charge is 
Answer: Frequency= 0.5 Hz
Period= 2s
Explanation:
2 sec= 0.5 Hz
0.5Hz= 2 sec
Answer:
B)
D)
Explanation:
Carnot cycle ;
This is the ideal cycle for all type of heat engine.All the process in the Carnot cycle is reversible processes ( those process does not leave any effect on the system as well as surrounding when the process is reversed is known as reversible process).It have four process in which two process is constant temperature and other two is isentropic or we can say that reversible adiabatic.
In the two process(constant temperature) only heat interaction take places and other two process(adiabatic) only work interaction take places.
So the option B and D is incorrect for Carnot cycle.
