Answer:
a)P =14288.4 W
b)P = 19.16 horsepower
Explanation:
Given that
m= 108 kg
Initial velocity ,u= 0 m/s
Final velocity ,v= 19.6 m/s
t= 2.9 s
Lets take acceleration of Cheetah is a m/s²
We know that
v= u + a t
19.6 = 0 + a x 2.9
a= 6.75 m/s²
Now force F
F= m a
F= 108 x 6.75 N
F= 729 N
Now the power P
P = F.v
P = 729 x 19.6 W
P =14288.4 W
We know that
1 W= 0.0013 horsepower
P = 19.16 horsepower
P =14288.4 W
Question:The complete question can be found in the attached image below.
Answer: Light passes through the eyes through the following correct order
cornea--> aqueous humor---> lens -------------------->vitreous humor.
Explanation:
The CORNEA is a dome shaped structure that covers the anterior part of the eye. Light rays passes through it first as it enters the eye. The AQUEOUS HUMOR is located anterior to the lens which nourishes the lens and helps to maintain intraocular pressure. Light rays pass through it to the LENS. The lens is a clear structure inside the eye that focuses light rays onto the retina. The light rays passes from lens to the VITREOUS HUMOR before reaching the retina. vitreous humor is a jelly-like substance that fills the center of the eye. I hope this helps, thanks
Answer:
moment of inertia I ≈ 4.0 x 10⁻³ kg.m²
Explanation:
given
point masses = 50g = 0.050kg
note: m₁=m₂=m₃=m₄=50g = 0.050kg
distance, r, from masses to eachother = 20cm = 0.20m
the distance, d, of each mass point from the centre of the mass, using pythagoras theorem is given by
= (20√2)/ 2 = 10√2 cm =14.12 x 10⁻² m
moment of inertia is a proportion of the opposition of a body to angular acceleration about a given pivot that is equivalent to the entirety of the products of every component of mass in the body and the square of the component's distance from the center
mathematically,
I = ∑m×d²
remember, a square will have 4 equal points
I = ∑m×d² = 4(m×d²)
I = 4 × 0.050 × (14.12 x 10⁻² m)²
I = 0.20 × 1.96 × 10⁻²
I = 3.92 x 10⁻³ kg.m²
I ≈ 4.0 x 10⁻³ kg.m²
attached is the diagram of the equation
The answer for this question should be TRUE
