Answer:
Explanation:
Force is the push or pull on object that can cause different things, like acceleration. According to Newton's 2nd Law of Motion, it is the product of mass and acceleration.
The mass of the wolf is 50.5 kilograms and the acceleration is 5.0 meters per square second. Therefore:
Substitute the values into the formula.
Multiply.
- 1 kilogram meter per square second is equal to 1 Newton.
- Our answer of 252.5 kg*m/s² is equal to 252.5 Newtons.
The force required is <u>252.5 Newtons</u>.
Answer:
Random errorrs
1) Variations in the level of the eye when we measure the dimensions of the cubic piece using the metric rule.
2) Possible vibrations or disbalance when we measure the mass of the of the cylinder.
Systematic errors
3) Wrong calibration for the balance and that represent a measurement wrong
Explanation:
Previous concepts
Random error represent an statistical error associated to the effect random in the experiment.
Systematic error is a "repeatable error associated with faulty equipment or a flawed experiment design", so is an error non controlled.
Solution to the problem
So as we can see we have two possible types of errors : random and systematic errors. For this stuation the list of 3 errors required are:
Random errors
1) Variations in the level of the eye when we measure the dimensions of the cubic piece using the metric rule.
2) Possible vibrations or disbalance when we measure the mass of the of the cylinder.
Systematic errors
3) Wrong calibration for the balance and that represent a measurement wrong
It should not be stored in a place where it is open to the air, as it can obtain diseases, bacteria and viruses just hanging out waiting for a host.
Answer:
<em>The force exerted by each string is 25 N</em>
Explanation:
<u>Net Force</u>
The net force is the vector sum of forces acting on a body. The net force is a single force that represents the effect of the original forces on the body's motion. It gives the particle the same acceleration as all those actual forces together as described by Newton's second law of motion.
The picture described in the problem is hanging at rest supported by two vertical strings. This means that the net force acting on it is zero.
Assume the magnitude of each of these equal forces is F, and the picture has a weight of W=50 N, thus the net force is:
F + F - W
The positive signs indicate an upwards direction and the negative sign means a downwards direction. Since the net force is zero:
F + F - W = 0
2F = W
F = W/2 = 50 N/2
F = 25 N
The force exerted by each string is 25 N
