A cave system with a mapped length of 369 miles:

594 km, 594,000 m, 59,400,000 cm

A waterfall that drops 1,180.8 ft :

0.35989 km, 359.89 m, 35,989 cm

A 20,250 ft tall mountain:

6.1738 km, 6,173.8 m , 617,380 cm

A canyon with a depth of 73,800 ft:

22.493 km, 22,493 m , 2,249,300 cm

Explanation:

Given:

The height or length of these natural wonders

To find:

The height or length of these natural wonders in kilometers, meters, and centimeters.

Solution:

(a) a cave system with a mapped length of 369 miles

Length of the cave system = 369 miles

$1 mile = 1.609 km\\369 miles=369\times 1.609 km=594 km\\1 km = 1000 m\\594 km = 594\times 1000 m= 594,000 m\\1 m = 100 cm\\594,000 m=594,000 \times 100 cm=59,400,00 cm\\$

(b) a waterfall that drops 1,180.8 ft

The height of the waterfall = 1,180.8 ft

$1 km= 3281 ft\\1ft=\frac{1}{3281} km\\1,189.8 ft=1,180.8 \times \frac{1}{3281}km=0.35989 km\\1 km = 1000 m\\0.35989 km=0.35989 \times 1000=359.89 m\\1 m = 100 cm\\359.89 m=359.89 \times 100 cm=35,989 cm\\$

(c) A 20,250 ft tall mountain.

The height of the mountain = 20.250 ft

$1 km= 3281 ft\\1ft=\frac{1}{3281} km\\20,250 ft=20,250 \times \frac{1}{3281}km=6.1738km\\1 km = 1000 m\\6.1738km=6.1738\times 1000=6,173.8 m\\1 m = 100 cm\\6,173.8 m=6,173.8 m\times 100 cm=617,380 cm\\$

(d) A canyon with a depth of 73,800 ft

The height of the canyon = 73,800 ft

$1 km= 3281 ft\\1ft=\frac{1}{3281} km\\73,800 ft=73,800\times \frac{1}{3281}km=22.493km\\1 km = 1000 m\\22.493km=22.493\times 1000=22,493m\\1 m = 100 cm\\22493 m=22493m\times 100 cm=2,249,300cm\\$

A particle is projected with velocity v0 directly up a slope which makes an angle α with the horizontal. Assume frictionless mot

Nikolay [14]

Answer:

a)T total = 2*Voy/(g*sin( α ))

b)α = 0º , T total≅∞ (the particle, goes away horizontally indefinitely)

α = 90º, T total=2*Voy/g

Explanation:

Velocity in the Y axis:

Voy=Vo*sinα

Time to reach the maximal height :

Kinematics equation: Vfy=Voy-at

a=g*sinα ; g is gravity

if Vfy=0 ⇒ t=T ; time to reach the maximal height

so:

0=Voy-g*sin( α )*T

T=Voy/(g*sin( α ))

Time required to return to the starting point:

After the object reaches its maximum height, the object descends to the starting point, the time it descends is the same as the time it rises.

So T total= 2T = 2*Voy/(g*sin( α ))

α = 0º , sinα=0

The particle goes totally horizontal, goes away indefinitely

T total= 2*Voy/(g*sin( α )) ≅∞

α = 90º, sinα=1

T total=2*Voy/g

Describe the process of how a bill becomes a law in at least 4-5 sentence

Lina20 [59]

Answer:

Step 1: A Bill Is Born

Anyone may draft a bill; however, only members of Congress can introduce legislation, and, by doing so, become the sponsor(s). The president, a member of the cabinet or the head of a federal agency can also propose legislation, although a member of Congress must introduce it.

Step 2: Committee Action

As soon as a bill is introduced, it is referred to a committee. At this point the bill is examined carefully and its chances for passage are first determined. If the committee does not act on a bill, the bill is effectively "dead."

Step 3: Subcommittee Review

Often, bills are referred to a subcommittee for study and hearings. Hearings provide the opportunity to put on the record the views of the executive branch, experts, other public officials and supporters, and opponents of the legislation.

Step 4: Mark up

When the hearings are completed, the subcommittee may meet to "mark up" the bill; that is, make changes and amendments prior to recommending the bill to the full committee. If a subcommittee votes not to report legislation to the full committee, the bill dies. If the committee votes for the bill, it is sent to the floor.

Step 5: Committee Action to Report a Bill

After receiving a subcommittee's report on a bill the full committee votes on its recommendation to the House or Senate. This procedure is called "ordering a bill reported."

Step 6: Voting

After the debate and the approval of any amendments, the bill is passed or defeated by the members voting.

Step 7: Referral to Other Chamber

When the House or Senate passes a bill, it is referred to the other chamber, where it usually follows the same route through committee and floor action. This chamber may approve the bill as received, reject it, ignore it, or change it.

Step 8: Conference Committee Action

When the actions of the other chamber significantly alter the bill, a conference committee is formed to reconcile the differences between the House and Senate versions. If the conferees are unable to reach agreement, the legislation dies. If agreement is reached, a conference report is prepared describing the committee members' recommendations for changes. Both the House and Senate must approve the conference report

Step 9: Final Action

After both the House and Senate have approved a bill in identical form, it is sent to the president. If the president approves of the legislation, he signs it and it becomes law. Or, if the president takes no action for ten days, while Congress is in session, it automatically becomes law.If the president opposes the bill he can veto it; or if he takes no action after the Congress has adjourned its second session, it is a "pocket veto" and the legislation dies.

Step 10: Overriding a Veto

If the president vetoes a bill, Congress may attempt to "override the veto." If both the Senate and the House pass the bill by a two-thirds majority, the president's veto is overruled and the bill becomes a law.

Which wave, A or B, has higher energy?

eduard

Answer:

Wave A.

Explanation:

The energy of a wave is directly proportional to the square of the amplitude.

If a wave has higher amplitude, it will have more energy. On the other hand, a wave having lower amplitude, it will have less eenergy.

In this case, we need to tell which wave has higher energy. Hence, the correct option is A because it has a higher amplitude.

A 5 cm spring is suspended with a mass of 3.8589 g attached to it which extends the spring by 1.5747 cm. The same spring is plac

lana66690 [7]

Answer:

charges of the beads is 1.173 × $10^{-15}$ C

Explanation:

given data

mass = 3.8589 g = 0.003859 kg

spring length = 5 cm = 0.05 m

extend spring x = 1.5747 cm = 0.15747 m

spring's extension = 0.0116 m

to find out

charges of the beads

solution

we know that force is

force = mass × g

force = 0.003859 × 9.8

force = 0.03782 N

so we know force for mass

force = -kx

so k = force / x

put here force and x value

k = -0.03782 / 0.1575

k = -0.24 N/m

and

force for spring's extension

force = -kx

force = -0.24 ( 0.0116) = 0.002784 N

so here

total length L = 0.05 + 0.0116 = 0.0616

so charges of the beads = force × L² / ke

charges of the beads = 0.002784 × (0.0616)² / (9 × $10^{9}$ )

so charges of the beads = 1.173 × $10^{-15}$ C
