A physical science teacher wants to demonstrate Newton's laws. She has 2 skateboards and takes them out to a flat parking lot. Two students are chosen. Kayla weighs 125 pounds and Steve weighs 175 pounds. Both push off a car with the same force. Which BEST describes the relationship between acceleration and mass? A Kayla will have a smaller acceleration because she has more mass.
B Steve will have a larger acceleration because he has more mass

C Kayla will have a larger acceleration because she has less mass.

C

Explanation:

if the mass is smaller the acceleration is larger

potential energy is directly proportional to height.

more height = more potential energy.

greatest increase in height = greatest increase in potential energy

where are the points with the greatest increase in height ?

has to be c-e or d-e .

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?

a. 27 ω

b. 40.5 a

c. 243 ω

d. 243 a

the correct answer is a. 27
