Answer:

You can test for hydrogen gas by putting a burning splinter near the gas. The splinter will gives out a 'pop' sound (mini explosion) if it is hydrogen gas

Explanation:

A splint is lit and held near the opening of the tube, then the stopper is removed to expose the splint to the gas. If the gas is flammable, the mixture ignites. This test is most commonly used to identify hydrogen, which extinguishes with a distinctive 'squeaky pop' sound.

Can someone please tell me...... What does it mean if you through up thew your nose and mouth at the same time!?
hodyreva [135]

if you're worried about youre health you're completely fine. (other than the fact you are throwing up, if your sick please see a doctor) but if the things you're worried about is that it can out of your nose, dont worry it happenes to a lot of people. Your nose and mouth are both connected to your throat and that sudden rush of fluids from your throat can confuse your body, Its like when you laugh while eating and then you accidently get food in your nose. Don't worry this isn't anything that is particulary bad but i will say that the vomiting is not good

An unwary football player collides with a padded goalpost while running at a velocity of 7.50 m/s and comes to a full stop after
frez [133]

Answer:

(a) the deceleration of the player is -80.36 m/s²

(b) the time the collision last is 0.093 s

Explanation:

Given;

Initial velocity of the football player, u = 7.50 m/s

Final velocity of the football player, v = 0

distance traveled = compression of the pad, s = 0.35 m

Part (a) the deceleration of the player

v² = u² + 2as

0 = 7.5² + (2 x 0.35)a

0 = 56.25 + 0.7a

- 56.25 = 0.7a

a = -56.25 / 0.7

a = -80.36 m/s²

Part (b) the time the collision last

v = u + at

t = (v - u)/a

t = (0 - 7.5)/ -80.36

t = - 7.5 / -80.36

t = 0.093 s
