Insulators do not allow electrons to move easily through them.
Answer:
rate of infusion is 900 mL/hr
Explanation:
given data
Infuse I1 = 1000 mL
delivers = 15 gtt/mL
Infuse I2 = 300 mL
time t= 20 min
rate = 60 mL/hr
to find out
rate of infusion
solution
we know here we give 300 mL infuse in 20 min
so here for 20 min
rate of infusion is express as
rate of infusion = I2 / t
rate of infusion = 300 / 20
rate of infusion = 15 mL / min
rate of infusion = 15 × 60 = 900
so rate of infusion is 900 mL/hr
Answer is: <span>canoe's kinetic energy is 136 J.
</span>m(canoe) = 17 kg.
v (speedcanoe) = 4 m/s.
E(canoe's kinetic energy) = ?
E = 1/2 · m(canoe) · v²(canoe).
E = 0,5 · 17 kg · 16 m²/s².
E = 136 J.
<span>The kinetic energy of a non rotating object of </span>mass m<span> traveling at a </span>speed v. <span>The standard unit of kinetic energy is the </span>joule.
Answer:
Free-fall is defined as the movement where the only force acting on an object is the gravitational force.
By the second Newton's law, we have that:
F = m*a
Where F = Force, m = mass, a = acceleration.
We can write this as:
a = F/m
And the gravitational force can be written as:
F = (G*M/r^2)*m
Where G is the gravitational constant, M is the mass of the Earth in this case, and r is the distance between both objects (the center of the Earth and the free-falling object)
As the radius of the Earth is really big, the term inside the parentheses is almost constant in the region of interest, then we can write:
G*M/r^2 ≈ g
And the gravitational force is:
F = g*m
And by the second Newton's law we had:
a = F/m = (g*m)/m = g
a = g
Then the acceleration does not depend on the mass of the object.
Then the thing that is common among the free-falling objects is the vertical acceleration.
Answer:
The smallest separation distance between the speakers is 0.71 m.
Explanation:
Given that,
Two speakers, one directly behind the other, are each generating a 240-Hz sound wave, f = 240 Hz
Let the speed of sound is 343 m/s in air. The speed of sound is given by the formula as :
To produce destructive interference at a listener standing in front of them,
So, the smallest separation distance between the speakers is 0.71 m. Hence, this is the required solution.
