We know that According to Newton's Second Law that :
Force acting on an object is equal to the Mass of that Object multiplied by the Acceleration of that Object.
Given Mass of the Car as : 2000 kg
Acceleration of the Car as : 2 m/s²
Force required to move the Car = 2000 × 2 = 4000 Newton
Answer:
B. -10.0
Step-by-step explanation:
-10.0² = -100
thus= -10.0 is the closest to -102 (square root)
V=120, l=8, h=1.5
W = V/hl
W=120/8(1.5) = 10
Answer: Jennifer didn't randomly assign participants to the control and experimental group.
Step-by-step explanation: In the scenario discussed above, Jennifer failed to perform a random assignment of the participants who took part in the survey, that is the experimental group, those who receive the treatment and the control group, those who don't. Random assignment is required in other to address the issue of bias in our experiment.
