Is light from a fire matter​

Physics

Answer:

Is fire matter? Matter is anything that has mass and occupies space. The flame itself is a mixture of gases (vaporized fuel, oxygen, carbon dioxide, carbon monoxide, water vapor, and many other things) and so is matter. The light produced by the flame is energy, not matter.

Two students are on a balcony 18.5 m above the street. One student throws a ball ver- tically downward at 13.8 m/s; at the same
lys-0071 [83]

Answer: 11.24m

Explanation:

Given that:

  • initial velocity of first ball, u_1= 13.8 m.s^{-1}
  • initial velocity of second u_2= -13.8 m.s^{-1} ( negative because thrown against the gravity)
  • time, t = 0.361 s
  • acceleration of gravity, g = 9.8 m.s^{-2}

Using the equations of motion:

To find the final velocity after the given time 0.361 second.

v=u+at ................ (1)

where:

  • v = final velocity of the body after time t under the influence of acceleration a (here g).

<em>Putting the values of the respective balls </em>

v_1= 13.8+ 9.8 \times 0.361

v_1= 17.3378 m.s^{-1}  

Similarly  

v_2= -13.8- 9.8 \times 0.361  ∵the body is thrown against the gravity will have decelerating effect.

v_2= -17.3378 m.s^{-1} ∵the body is still moving up with this velocity

<u>Now, using the eq. </u>

v^{2}=u^{2}+ 2a.s.............................(2)

where, the symbols have usual meaning as above and:

  • s= distance covered by the body.

Putting the respective values in eq. (2)

For the body in the first case:

17.3378^{2}= 13.8^{2} + 2 \times 9.8 \times s

s= \frac{17.3378^{2}-13.8^{2}}{2 \times 9.8}

s = 5.62m

For the body in the second case:

(- 17.3378)^{2} = (- 13.8)^{2}- 2 \times 9.8\times s

s= \frac{300.6 - 190.44}{-2 \times 9.8}

s=- 5.62m

∴The bodies are 2 \times 5.62m= 11.24m apart from each other from the point from which they are thrown.

An object travels at a speed of 5m/s for 1 minute. What is the distance travelled by car.
-BARSIC- [3]

Answer:

D = 300

Explanation:

Speed = 5 m/s

Time = 1 m = 60sec (now both variables have the unit of seconds)

NOTE: Equation: Distance (D) = Speed (S) X Time (T)

Now, fill in your variables:

D = S X T

D = 5 X 60

D = 300
