I'm afraid you're not paying attention. This question is loaded with
all the important words, and you don't recognize Newton's second
law of motion. Didn't you notice the "force", "acceleration", and
"mass" all over the place in there ?
Newton's 2nd law: Force = (mass) x (acceleration)
The answer is going to be 'mass', so let's divide
each side of Newton's law by 'acceleration':
Mass = (force) / (acceleration)
Now, just write in the numbers that the question gave you:
force = 60 newtons
acceleration = 4 m/s²
Here's the equation again: Mass = (force) / (acceleration)
= (60 N) / (4 m/s²)
= 15 kg .
The answer is probably light years if your looking for something specific it could also be an Astronomical unit or Distance unit but mainly look for LIGHT YEARS
Answer:
coasting down hill on a bicycle
Explanation:
Coasting down the hill on a bicycle is a typical example of how kinetic energy is being transformed to potential energy in a system.
Kinetic energy is the energy due to the motion of a body, it can be derived using the expression below;
K.E = 
m v²
Potential energy is the energy due to the position of a body. It can be derived using;
P.E = mgh
m is the mass
v is the velocity
g is the acceleration due to gravity
h is the height
Now, at the top of the hill, the potential energy is at the maximum. As the bicycle coasts down the potential energy is converted to kinetic energy.
Answer:
The answer is D.
Explanation:
An example of a weak base is ammonia. It does not contain hydroxide ions, but it reacts with water to produce ammonium ions and hydroxide ions. The position of equilibrium varies from base to base when a weak base reacts with water. The further to the left it is, the weaker the base.
