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
Answer:
Digestion begins in the mouth, when you chew.
Answer:
Explanation:
As we know that the magnitude of electric field intensity is given as
now we know that intensity of the wave is given as the product of energy density and speed of the wave
so intensity is the energy flow per unit area per unit of time
so the energy that flows through the area of 0.0259 m^2 in 11.7 s is given as
Answer:
<h2>10 N</h2>
Explanation:
The force acting on an object given it's mass and acceleration can be found by using the formula
force = mass × acceleration
From the question we have
force = 2 × 5
We have the final answer as
<h3>10 N</h3>
