Answer:
-14-6=-20
Step-by-step explanation:
the negative sign gives you a negative 6, which you can subtract from -14, giving you -20.
KE = 0 (because velocity is 0)
PE = mgh = 2kg*9.8m/s^2*40m= 784 joule
<u>Explanation:</u>
KE stands for kinetic energy. In physics, the kinetic energy of an object is the energy that it possesses due to its motion. It is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity.
Having gained this energy during its acceleration, the body maintains this kinetic energy unless its speed changes. Since in this case, the building is still and therefore it does not have any kind of kinetic energy because there is not acceleration.
No nether are a prime number because they have a remainder and prime numbers <span> can only be divided without a remainder by itself and one

Answer:
24 ft^2
Step-by-step explanation:
Area of a triangle
A = 1/2 b*h
We know the base is 8 ft and the height is 6 ft
A = 1/2 (8) (6)
= 1/2 (48)
= 24 ft^2
Answer: 36.
Solve in order of PEMDAS - parentheses, exponents, multiplication, division, addition and subtraction. 21/7= 3. 3^3 is 3*3*3=27. 3+ 6 + 27= 36.
