Using hookes law find the distance a spring with am elastic constant of 4 N/cm will stretch if a 2 newton force is applied to it

Suppose you take two non-zero displacements represented by vectors A & B.The magnitude of A is 5 m and the magnitude of B is

olga55 [171]

Answer:

a. When the total displacement is -(A + B)

b. A + B = 1 m or -(A + B) = -11 m

c. 0 m

Explanation:

a. Under what circumstances can you end up back at your starting point?

If we have the displacement A and displacement B. The total displacement is A + B. We would end up at the starting point if we take a displacement -(A + B) from point B

b. What is the magnitude of the largest displacement you can end up from the starting point?

The maximum displacement we can obtain is when A and B are in the same direction. So A + B = 5 m + 6 m = 11 m or -A - B = -(A + B) = -11 m.

c. When A and B are perpendicular, what is the component of B in the direction of A?

Since A is perpendicular to B, the angle between A and B is 90°

So the component of B in A,s direction is Bcos90° = B × 0 = 0 m

Lottery balls are thrown into a hopper and are set into motion by air forced through the container. each ball has a mass of 0.00

Marina CMI [18]

In this three body system total kinetic energy remains constant:
$E_{k} = constant =0.0268 J$

$E_{k} = E_{k1}+ E_{k2}+ E_{k3}$
If we assume that upwards movement is positive and downwards movement is negative the formula is:
$E_{k} = E_{k1}- E_{k2}+ E_{k3}$

Formula for kinetic energy is:
$E_{k} = \frac{m v^{2} }{2}$

Now we have:
$E_{k} = \frac{m v_{1} ^{2} }{2} -\frac{m v_{2} ^{2} }{2} +\frac{m v_{3} ^{2} }{2} \\ E_{k} = \frac{m}{2} (v_{1} ^{2}-v_{2} ^{2}+v_{3} ^{2}) \\ \\ 0.0268= \frac{0.0044}{2} (1.3 ^{2}-1.66^{2}+v_{3} ^{2}) \\ \\ 0.0536=0.0022(1.69-2.7556+v_{3} ^{2}) \\ \\ v_{3} ^{2}=25.43 \\ \\ v_{3} =+-5.04$

We got two solutions: positive and negative. The speed is 5.04 m/s and direction can be upwards and downwards.

What type of energy is related to kinetic energy of all the particles in a sample of matter

pshichka [43]

The kinetic molecular theory of matter offers a description of the microscopic properties of atoms (or molecules) and their interactions, leading to observable macroscopic properties (such as pressure, volume, temperature). An application of the theory is that it helps to explain why matter exists in different phases (solid, liquid, and gas) and how matter can change from one phase to the next.

Alexxx [7]

HELP ME PLEASE

Silently he crept through jagged thornbushes. Bare feet moved swiftly over hot, arid soil to the edge of a waterhole where the kudu was drinking. The great animal suddenly looked up, spiral horns curving sharply into the endless African sky. Nsue did not reach for his pouch of poisoned arrows. He had no heart for killing. This would not be the day he would change his childish boyhood name.

How does paragraph 1 contribute to Nsue’s development?

A.

It establishes Nsue’s disappointment at not finding a suitable animal to bring to the feast.

B.

It establishes Nsue’s apprehension of participating in the Festival of the New Moon.

C.

It establishes Nsue’s desire to become a great storyteller like Gao, the Old One.

D.

It establishes Nsue’s motivation to find something to take to the feast.

Newton’s ______ law of motion states that "an object at rest will stay at rest, and an object in motion will stay in motion, unl

Musya8 [376]

Newton’s <u>first</u> law of motion states that "an object at rest will stay at rest, and an object in motion will stay in motion, unless acted on by an unbalanced force.

It is possible to consider Newton's first law to be the law of inertia. It helped us realise that when a body is at rest, it will remain at rest until an external force is applied to it, or if a body is travelling at a constant speed, it will stay moving until an external force is applied.

Only when net force is applied will a body move from its resting position. An illustration of this law can be seen when a passenger in a car fastens their seat belt. Both stationary and moving objects are covered by this law.
