Answer:
This is physics. By the way look the explanation.
Step-by-step explanation:
The formula of Potential Energy is E=mgh, where m is the mass of the object, g the gravitational, and h the height of the object. Given that the potential energy of the object is 150 Joules at 3 meters height, Represent m=E/(g*h), considering g=9.8 m/s^2(Because this value was used for the first object), we get m=150/9.8/3=5.102
Rounding to 2 decimals` 5.10 kg
Answer:
(15c + 8)(a + b).
Step-by-step explanation:
15c·(a+b)+8·(b+a)
(a + b) is common to both parts:
= (15c + 8)(a + b).
Answer:
A = 2.25 pi in^2
Step-by-step explanation:
The circumference of a circle is 3pi
so d = 3
Area of circle = pi r^2
r = 3/2 = 1.5
A = (1.5)^2 pi
A = 2.25 pi in^2
