A body moving with a velocity of 20 m/s begins to accelerate at 3 m/s2. How far does the body move in 5 seconds?

Norma-Jean [14]

The distance covered will be:

$d = v_0\cdot t + \frac{1}{2}a\cdot t^2 = 20\frac{m}{s}\cdot 5\ s + \frac{5}{2}\frac{m}{s^2}\cdot 5^2\ s^2 = \bf 162,5\ m$

The correct answer is D).

You're at the zoo and have a big red 1.80 L helium balloon. The barometric pressure today is 785 mmHg. Then you hear the roar of

fomenos

Answer: The volume of the balloon up there is 6.192 L.

Explanation:

Given: $V_{1}$ = 1.80 L, $P_{1}$ = 785 mm Hg (mm Hg = 0.00131579) = 1.032 atm

$P_{2}$ = 0.300 atm, $V_{2}$ = ?

Formula used to calculate volume is as follows.

$P_{1}V_{1} = P_{2}V_{2}$

Substitute the value into above formula as follows.

$P_{1}V_{1} = P_{2}V_{2}\\1.032 atm \times 1.80 L = 0.300 atm \times V_{2}\\V_{2} = 6.192 L$

Thus, we can conclude that the volume of the balloon up there is 6.192 L.
