Why car speed is not considered as car velocity?​

Physics
1 answer:
grigory [225]4 years ago
4 0

Answer:

Cause its scalar quantity

Explanation:

since speed does not take directions into consideration, it is considered to be a scalar quantity. On the other hand, the velocity of an object does not take into account direction, thus making it a vector quantity.

The power output of a laser is measured by its wattage, the number of joules of energy it radiates per second (1 W = 1 J s-1). A
viva [34]

Explanation:

It is given that,

Wavelength of red light, \lambda=676.4\ nm=676.4\times 10^{-9}\ m

Power of the laser, P=300\ mW=0.3\ W

(a) The energy carried by each photon is given by :

E=\dfrac{hc}{\lambda}

E=\dfrac{6.63\times 10^{-34}\times 3\times 10^8}{676.4\times 10^{-9}}  

E=2.94\times 10^{-19}\ J

(b) Let n is the number of photons emitted by the laser per second. It can be calculated as :

n=\dfrac{Power}{Energy\ of\ one\ photon}

n=\dfrac{0.3}{2.94\times 10^{-19}}      

n=1.02\times 10^{18}\ photon/s

Hence, this is the required solution.

How long will it take a car to go from a complete stop to 44 km/hr if they are accelerating at 5 km/hr?
Aleonysh [2.5K]

<u>Solu</u><u>tion</u><u> </u><u>:</u><u>-</u>

Given that ,

  • Initial Velocity of car = 44km / hr.
  • Final Velocity of car = 0km / hr.
  • Acceleration = -5km/hr².

To Find :

  • Time taken to stop the car .

So , here use first equⁿ of motion which is ,

\boxed{\red{\bf\dag v = u + at }}

where ,

  • v is final Velocity.
  • u is Initial velocity.
  • a is acceleration.
  • t is time taken.

Now , substituting the respective values ,

\tt:\implies v=u+at

\tt:\implies 0 = 44 + (-5)t

\tt:\implies -44 = -5t

\tt:\implies t=\dfrac{44}{5}

\underline{\boxed{\red{\tt \longmapsto Time\:\:=\:\:8.8hrs.}}}

\boxed{\green{\bf\pink{\dag} Hence\:time\:taken\:to\:stop\:the\:car\:is\:8.8hrs.}}
