If the statistical analysis shows that the significance level is below the cut off value they have set (either 0.05 or 0.01) they reject the null hypothesis and accept the alternative hypothesis
Answer:
0.8m per second
Explanation:
we measure speed as distance over time
distance=8m
time=10s
therefore speed = 8/10
=0.8m per second
Answer:
Option D
4200 W
Explanation:
Power, P is also given as the product of voltage and current, expressed as P=VI
Here, P is power, V is voltage in the xircuit and I is current theough voltage.
Taking 12 V for voltage across and 350A for current across circuit then power will be
P=350*12=4200 W
Therefore, option D is correct.
I think this one's B. energy and work are both measured in joules.
Because static electricity build up in our homes because we have the heaters on which suck moisture out of the air.
