Depends on what type of gass

I think you sometime can but most of the time can't. Most gases are in color containers. That makes it kind of hard to answer this question. I hope this helps!

A 2.51 kg ball is attached to a ceiling by a 1.19 m long string. The height of the room is 3.45 m. The acceleration of gravity i

ANTONII [103]

Answer:

55,42 J

Explanation:

Since the height of the room is 3.45 m (distance between the floor and the ceiling) the difference between this value and the length of the rope 1.19 m; it will be equal to (3.45-1.19) =2.26 m. If we take as a reference point (Ep=0) the floor of the room, then the potential energy will be equal to Ep = M * g * h, replacing values in this equation (2.5 kg * 9.81 m/s2 * 2.26 m) will be 55,42 (N * m) or Jules.

A basketball player throws a basketball m = 1 kg straight up with an initial speed of v0 = 9.5 m/s. The ball leaves his hand at

brilliants [131]

To solve this problem we will apply the concepts related to energy conservation. So that the initial energy on the system is equivalent to the final energy.

The initial or final energy will also be the TOTAL mechanical energy of the body.

In the case of the initial energy we will have two types of energy on the body: Kinetic energy and potential energy.

For the case of the final energy we will only have the potential energy in terms of the height $h_m$ , the mass m, and the gravity g

$E_i = E_f$

$KE_i + PE_i = PE_f$

$\frac{1}{2} mv_0^2 +mgh_0 = mgh_m$

$E = mgh_m$

The total mechanical energy will be equivalent in the terms required, to the final potential energy.

A car advertisement states that a car can accelerate at 2 m/sec. The car starts from rest and accelerates to 70 km/hr. How much

Reptile [31]

Answer:

9.72s

Explanation:

$\pink{\frak{Given}}\begin{cases}\textsf{ A car starts from rest.}\\\textsf{It has an acceleration of 2m/s$^2$.}\\\textsf{ The final velocity of the car is 70km/hr.}\end{cases}$

Here we need to find out the time that the car took to achieve the velocity of 70km/hr after starting from rest . Firstly convert the final velocity in m/s by multiplying it by 5/18 , as ,

$\longrightarrow\sf 70km/hr = 70 \times \dfrac{5}{18} m/s =\bf 19.44\ m/s$
