The gravitational potential energy:
E p = m x g x h
where m is the mass and h is the height;
m = 50 kg, g = 9.81 m/s² , h = 40 m
E p = 50 kg x 9.81 m/s² x 40 m
Answer:
E p = 19,620 J = 19.62 kg
I dont see a problem here!!!!!!!!!
False because you would subtract 12 and then your answer becomes 8.
Answer:
a) x = 260
b) g = 218
c) z = 30
d) h = 5
Step-by-step explanation:
a)
Predict a number; let's say x = 225
Too low; try with a higher number; let's say x = 270
Too high, we're closer.
x = 260
--------------------------------------------------------------------------------------
b)
let's say g = 230
Too high. Try g = 221
We're almost there. Let's try with g = 218
----------------------------------------------------------------------------------------
c)
Let's try with z = 15
Too low; try a higher number. z = 30
--------------------------------------------------------------------------------------------
d)
Let's try with h = 6
Too high; let's try with h = 5
The elephant lost 4 pounds each month. Because he is losing weight, and not gaining weight, you have to make the answer negative
