Answer:
-5n
Explanation:
you have the positive force meaning the right which is acting with 5 Newton's. The negative we can assume to be the 10 Newton's to the left if you subtract them the resultant force should be -5 so ,5 Newton's to the left
Work = (force)x(distance)
Since we're lifting, the 'force' is the weight of the apple.
Weight = (mass)x(gravity)
Weight = (0.180 kg)x(9.8 m/s^2)
Weight = 1.764 Newtons
2.0 J = (1.764 N) x (distance)
Distance = 2.0J / 1.764N
Distance = 1.13 meters
According to newton's second law of motion F=ma , but here we have to find a so a=f/m ,a=8.11/1028=0.007m/sec² or 7×10‐3m/sec2
We will use two definitions to solve this problem. The first will be given by the conservation of energy, whereby the change in kinetic energy must be equivalent to work. At the same time, work can be defined as the product between the force by the distance traveled. By matching these two expressions and clearing for the Force we can find the desired variable.
Thus the force acting on the sled is,
Replacing,
Therefore the Force acting on the sled is 32N
Answer:
Place the north pole of a magnet next to the north pole of another magnet.
Explanation:
Looking at the comments, we can see that the options are:
Place the south pole of a magnet next to the north pole of another magnet.
Place the north pole of a magnet next to the north pole of another magnet.
First, we know that a positively charged particle will repel another positively charged particle.
The same thing happens for magnetic forces (usually we define a magnetic flow from the south pole to the north pole, so we can define the south pole as the "positive" and the north pole as the "negative", but this is only notation and do not really matter), a south pole of a magnet will repel another south pole of a magnet (and the same happens for the north poles)
Then the correct option is:
Place the north pole of a magnet next to the north pole of another magnet.
