The object is moving with constant speed means there is no change in speed Hence the acceleration is 0
Where, u is initial speed,
v is final speed
t is time taken and
a is acceleration
a = ( v-u) /t
a =(0)/t because u=v
a=0
Therefore, Acceleration is 0
Answer:
the air is being stopped in the pocket of the parachutes theys why the parachute has a certain shape so that the air that gets caught inside of it as the skydiver goes down slows down the landing
Answer:
With all of that information, he's telling us the train's VELOCITY.
Explanation:
Velocity is a vector quantity made of two parts: speed and direction.
Answer:
n = 1.89 x 10¹⁹ photons/s
Explanation:
given,
Power of bulb = 100 W
Visible light = 5 W
wavelength of the visible light = 600 nm
number of photons emitted per second
using formula of wavelength
energy of photon
U = h υ
U = 6.63 x 10⁻³⁴ x 4 x 10¹⁴
U = 2.65 x 10⁻¹⁹ J
number of photon
n = 1.89 x 10¹⁹ photons/s
