Answer:
1st one is 11.2. The 2nd one is 24.
Step-by-step explanation:
Answer:
depends on the force acting on the two objects. For the gravitational force the formula is P.E. = mgh, where m is the mass in kilograms, g is the acceleration due to gravity (9.8 m / s2 at the surface of the earth) and h is the height in meters.
Step-by-step explanation:
An equivalent expression would be 4v + 28.
Answer:
Required slope = - 6
Step-by-step explanation:
Parallel lines have same slope.
(x₁ , y₁) = (3 , -5) & (x₂ , y₂) = (1, 7)

![= \frac{7 - [-5]}{1-3}\\\\=\frac{7+5}{1-3}\\\\=\frac{12}{-2}\\\\= -6](https://tex.z-dn.net/?f=%3D%20%5Cfrac%7B7%20-%20%5B-5%5D%7D%7B1-3%7D%5C%5C%5C%5C%3D%5Cfrac%7B7%2B5%7D%7B1-3%7D%5C%5C%5C%5C%3D%5Cfrac%7B12%7D%7B-2%7D%5C%5C%5C%5C%3D%20-6)
Slope of the a line parallel to a line = -6
