Answer:
252 J
Step-by-step explanation:
The potential energy of the rock is the product of its height and its weight:
PE = (mg)h = (12 N)(21 m) = 252 N·m = 252 J
The rock's potential energy is 252 joules.
First u would multipli 8*4=32
next u would divide 32/6=5.3

Answer:
330
Step-by-step explanation:
Hello There!
The shown figure is a trapezoid with the following dimensions:
Height - 11m
Base 1 - 41m
Base 2 - 19m
Given this information we need to find the area
Remember the formula for the area of a trapezoid is

where a and b are bases and h is the height
Because we are given all of the information needed to calculate the area all we have to do is plug in the values into the formula
So...

In conclusion the area of the figure is 330 square units
