Well considering that car A is going twice as fast, than car B, it would most likely also take twice as long for car A to stop than for car B, so with that in mind, you would need twice as much distance.

Para sa aking Mahal na Magulang

Tula ni Eden Diao Apostol

Ang buhay kong ito’y sa inyo nagmula

Pangalawa sa Diyos na s’yang lumikha

Utang ko sa inyo ang aking hininga

Minahal, hinubog ng inyong kalinga.

Mga sakripisyo’y sadyang hindi biro

Mula ng ako’y iniluwal sa mundo

Pag-ibig na iniukol sa ‘ki’y totoo

Pagmamahal ninyo’y nagsilbing lakas ko.

Ako’y tinuruan ng magandang asal

Sa gitna ng hirap ako’y pinag-aral

Upang ‘di mapariwara ang aking buhay

Diplomang natanggap sa inyo ini-alay.

Ngayon ang buhay ko ay sadyang kay-palad

Pangarap ko’y unti-unting natutupad

Ito’y bunga ng ‘nyong dakilang paglingap

Sa ‘king puso’y walang hanggang pasalamat.

Pagkalinga ng Magulang

Tula ni Laurence B. Reyes

Saking pag unlad baon ang inyong aral

Bilang papuri at sa inyo ay parangal

Ang walang katapusang pasasalamat

Ang pag ibig at karangalan ang dapat.

Sa aking pagmulat sa mundo ng kaligayahan

Kayo ang aking lagging nadadamhan

Sa aking paglaki dama pa rin ang aruga

Hindi ko makalimutan ang pagmamahal at aruga

Sa pag aaruga at pag aalaga

Sa pag ibig at iyong pagkalinga

Sadyang tinakda ng ating kapalaran

Patungo lamang sa tuwid na daan.

Ang pagbibigay ng natatanging aral

Ang inyong anak ay nabusog sa pangaral

Ang inyong pag ibig na para sa akin

Tanging kabutihan ang nais hatid.

Naging daan patungo sa kabutihan

Naging daan ng pag ibig sa tahanan

Kayo ang pundasyon, mabuting samahan

Maraming salamat sa pagmamahal.

The banking angle in a turn on the Olympic bobsled track is not constant, but increases upward from the horizontal. Coming aroun
zlopas [31]

Answer:

the curve inclination is increased so that a weight component helps keep the car on track

Explanation:

In the sledging competition these devices go at quite high speeds over 100 km/h, so when reaching the curves the friction force is not enough to keep the car on the track. For this reason,  the curve inclination is increased so that a weight component helps keep the car on track.

In general we can solve Newton's second law for this case, with the condition of no friction, it is found that

   V² = r g tan θ

 Where V is the maximum velocity, r is the radius of the curve a, θ is the angle of the inclination

Answer:

Medium

Explanation:

Electromagnetic waves (light, electricity) can travel through space, which has no medium (air), while mechanical waves cannot. The main medium for mechanical waves is air, and without the medium, the wave cannot travel. This is why you cannot hear sound in space.

Why is it so important to know how the parts of a can opener work
Dafna1 [17]

Answer:

Hi there!

There are many possible answers!

My best guesses are:

1) Knowing how they work will prevent injury! For example, knowing that the gears twist will stop you from putting your finger in it!

2) Allowing you to use it! Knowing how to line up the edge of the can with the tool will let you use it properly!

Hope this helps
