Power
is calculated by dividing the work done with the time interval of the motion.
Work, on the other hand, is force times the distance traveled. Therefore, we
can calculate as follows:<span>
Power=W/t = mgd/t
90 = 60(9.81)d / 40
d = 6.12 m
Number of steps = 20/6.12 = 3.27 or 3 steps</span>

he is good science teacher❣❣❣
Q=l^2 times R times t
Where Q - heat, I -current, R - resistance and t is time
If you increase I twice (and it's squared), than Q gonna went up 4 times (2 squared).
Choose last
Answer:
2400 cm
Explanation:
The milky way has diameter of 100000 light years.
The local group is the collection of galaxies which includes the milky way.
10 million light years is the diameter of the local group.
Hence, the diameter of the scale model of the local group would be 2400 cm
