A cell is a membrane-covered structure that contains the materials for life. Just as the atom is the building block of matter, the cell is the building block of life.
Answer:
The anchor point is 166.86 ft apart
Explanation:
The antenna and 2 wire from traingle ABC ( figure given below). we can immediately apply the law of sines
there are two angles for which this happens c = 52.18 or c = 127.81 degree
But 127.81 + 65 > 180 so the only valid angle for c is 52.18 degree.
that mean A = 180 - B - C = 62.82 DEGREE
THUS required distance a is by the law of sines
Answer:No it does not the chemical equation is unbalanced,this is because according to the law of conservation it states that mass cannot be created or destroyed ,the chemical equation N₂ + H₂ → NH₃ shows that energy has been created which is not possibly so the correct balanced chemical is equation is 1N₂ +3H₂ → 3NH₃
Explanation:
Answer:
420J
Explanation:
Given parameters:
Force = 2 x 10¹N
Speed = 3m/s
Time = 7s
Unknown:
Work done = ?
Solution:
Work done is the force applied on a body to move it through a particular distance.
Work done = force x distance
Now, let us find the distance;
distance = speed x time
distance = 3 x 7 = 21m
So;
Work done = 2 x 10¹ x 21 = 420J
Answer: If the forces on an object are balanced, the net force is zero. If the forces are unbalanced forces, the effects don't cancel each other. Any time the forces acting on an object are unbalanced, the net force is not zero, and the motion of the object changes.
