Answer:
the force decreases
Explanation:
Gravitational force is depending on it's mass and the distance between two object
The attachment shows us to understand relationship of it's
F ∝ 1/ (r)2
there for gravitational force is inversely proportional to it's distance . when distance between two object is increased, Then force will be decreased
Answer: 24.7 degrees Max
Explanation:
m*g = 3 * 9.8 = 29.4 N. = Wt. of book.
Fp = 29.4*sin A = Force parallel to the
plank.
Fn = 29.4*Cos A = Force perpendicular to
the plank.
Fs = u*Fn = 0.46*29.4*Cos A
Fp-Fs = m*a
29.4*sin A - 0.46*29.4*Cos A = m*0 = 0
29.4*Sin A = 0.46*29.4*Cos A
Sin A = 0.46*Cos A
Divide both sides by Cos A:
Sin A/Cos A = 0.46
Replace Sin A/Cos A with Tan A:
Tan A = 0.46
A = 24.7 degrees Max.
Answer:
solid to gas or gas to liquid
Explanation:
welcome
Answer:
Giardia lamblia, a microorganism, invades the cells of the small intestine in humans,
absorbs nutrients, and causes diarrhea in its host is an example of parasitism
Explanation:
Ants protect aphids from their predators, ladybugs, in return for honeydew.is an example of mutualism
Two species of grass in an ecosystem require water and the same nutrients is an example of competition
A barnacle attaches to a whale for transport, but does not affect the whale is an example of commensalism.
Final velocity = 30 m/s
acceleration = 30/20 = 1.5 m/^2
