Answer:
The right answer is 8.9 x 10^-3 M/min
Explanation:
A → B
-d [A]/dt = K [A]
ΔA/Δt = - (C2 -C1)/t2 - t1
= - (0.11 - 0.91)/90
= 8.9 x 10^-3 M/min
Solution :
From the given data,
For the spherical shell is 
where x is the radius of gyration and the acceleration of a rolling body on an inclined plane = a
Therefore,



= 0.6 x 9.81 x sin ( 29.7)




Δt = 1.411 s
Answer:
the answer is ture
Explanation:
because the energy substances must absorb in order to change from liquid to gas
the action and reaction do not lead equilibrium if action and reaction force react on different objects
Answer:
<h3>25km/hr</h3>
Explanation:
Velocity is the change in displacement of a body with respect to time.
Velocity - Displacement/time
Given
displacement = 76km
Time = 3hours
Substitute the given parameters into the formula;
Velocity = 75km/3hrs
Velocity = 25km/hr
Hence the velocity of the narwhal is 25km/hr
