The diagram below shows a horizontal 12-newton
force being applied to two blocks, a and b, initially
at rest on a horizontal, frictionless surface. block a
has a mass of 1 kilogram and block b has a mass of 2
kilograms.

the answer is 46 mls because when you add the speed per second it increses the speed

when a device is used in a circuit in which the voltage is 81 v, the current flowing through the device is 3 a. what is the resistance of the device?

b. 40.5 a

c. 243 ω

d. 243 a

the correct answer is a. 27
