Answer:

H,G,E,D,C,B,A,I,F

Explanation:

F is an ignious intrusion and I cross cuts H to A so it must be newer.

Explanation:

The rod can be in equilibrium only if the resultant force is 0 and the moment around any point of the rod must be equal to 0.

We have to take moments around the pivoted point.

Moment = Force × Perpendicular distance to the force

For the rod to be in equilibrium,

Clockwise moment - Anticlockwise moment = 0

Clockwise moment = Anticlockwise moment

The distance between pivoted point and the weight of rod = 50 cm - 30 cm = 20 cm

So 20 cm× 1.2 N produces a Clockwise moment

If Perpendicular distance between pivoted point and 2N load is x,

Anticlockwise moment = x × 2N

20 cm× 1.2N = 2N × x

x = 12 cm

So 2 N load is at 12 from the pivoted point.

From the left edge of the meter ruler, 2N load is at 30-12 cm distance

= 18 cm

Answer: 18 cm

moon Triton, Neptune's largest moon Triton

The moon Triton is the captured moon which most likely originated in the Kuiper belt.

This is defined as  a donut-shaped region beyond Neptune and has an extension from 30 to 50 AU or more from the Sun.

The moon Triton is the captured moon which originates from this belt thereby making it the most appropriate choice.

Explanation:

Evaporation

Answer:

Salt from sea water is obtained by the process of evaporation. ... The sea water evaporates due to the sun's heat and solid salt is left behind. The left salt is collected and refined to get purified salt. Hence, salt is obtained from sea water by evaporation.

The natural light display called aurora borealis is located in the northern

hemisphere.

There are two types of aurora which are called aurora borealis and aurora

australis. The aurora borealis is located in the Northern hemisphere while

the aurora australis is located in the Southern hemisphere.

They receive their energy through the interaction of charged particles

on the Sun and Earth to produce the light display. An example

of the interaction involves solar wind with atoms of the upper atmosphere.

The key phrase which describes zero (0) initial velocity is from rest.

When the velocity of an object at initial time is zero (0), it implies that the change in the displacement of the object with time is zero

[tex]v= \frac{\Delta x}{\Delta t} \\\\v_0 = 0[/tex]

Generally, when an starts its motion from rest, the initial velocity of the object will be zero. As the object acquires more momentum, the velocity increases with time.

Thus, we can conclude that the key phrase which describes zero (0) initial velocity is from rest.

Answer:

39.240 W

Explanation:

Let's start by calculating the work done by the engine. We can assume that it is the same work done by the weight of the object to bring it from 40m to the surface: as much energy it takes to bring it up, the same ammount it takes to bring it down. Said work is [tex]w= \vec F\cdot \vec{h} = mg h = 1000 \times 9.81\times 40 = 392.400 J[/tex]

At this point we can simply apply the definition of power, that is [tex]P = \frac wt[/tex], to get the power of the engine is [tex]39.240 W[/tex]

Answer:

P=39200W

Explanation:

P=(mgh)/t

P=(40×9.8×1000)/10

P=39200W

The spring in the dart gun is compressed by 0.16 m

From the question given above, the following data were obtained:

Spring constant (K) = 50 N/m

Potential Energy (PE) = 0.640 J

The compression experience by the spring can be obtained as follow:

PE = ½ke²

0.64 = ½ × 50 × e²

0.64 = 25 × e²

Divide both side by 25

e² = 0.64 / 25

Take the square root of both side

e = √(0.64 / 25)

e = 0.16 m

Therefore, the spring is compressed by 0.16 m

Answer: 225N to the right

Explanation:

The pedaling force is to the right and of 325N.

The air resistance is to the opposite side (in this case to the left) of 100N.

To find Net force of an object with two opposite forces acting on them then we have to subtract the smaller force from the bigger force and but the direction of the bigger force, so

325N-100N=225N

The greater force is towards the right proving the direction of the Net force is to the right.

Therefore the Net force is 225N to the right.
