The correct answer to the question is : The ostrich is motion.
EXPLANATION:
As per the question, the momentum of ostrich P = 5400 Kg. Km/hr.
The mass of the ostrich m = 120 Kg.
The momentum of a body is defined as the product of mass with velocity.
Mathematically P = mv.
The velocity of the ostrich v is calculated as -
v = 
= 
= 45 Km/hr
Hence, the ostrich is in motion as it is moving with a velocity of 45 Km/hr.
Answer:
3 pounds and 14.082 ounces (?)
Explanation:
F= M x 9.8
1.76 x 9.8 = 17.25 N
It carry its loads from the sand and outher partials in it
Answer
given,
wavelength (λ) = 650 nm
angle = 5°
using bragg's law



d = 7.46 x 10⁻⁴ cm
number of slits per centimeter
= 
b) wavelength of two rays 650 nm and 420 nm

d = 2 x 10⁻6 m
we now,

for 650 nm


θ = 40.54°
for 450 nm


θ = 24.83°
now, difference
|θ_{650} -θ_{420}| =40.54°-24.83°
|θ_{650} -θ_{420}| =19.71°
m = mass of the roller coaster = 500 kg
h = height of the hill = 80 m
v = speed of the roller coaster at the bottom of the hill = ?
using conservation of energy
kinetic energy at the bottom of the hill = potential energy at the top of hill
(0.5) m v² = m g h
(0.5) v² = g h
inserting the values
(0.5) v² = (9.8) (80)
v = 39.6 m/s
hence the speed at the bottom comes out to be 39.6 m/s
