The answer would be:
Houlette de berger.
Answer:
The marginal revenue is positive when Roland sells 144 driers per week ( D
Explanation:
Elasticity of demand = -0.463
P = $127
116 hair dryers sold per week ( q )
demand function is differentiable
<u>prove the true statement below</u>
Revenue = price per unit * quantity
determine the Marginal revenue = dr / dq
∴ MR = P + q dp/dq
price elasticity of demand E(p) = - dq / dp * p/q
where : E ( p ) = - 0.463 , q = 116 , p = $127
q * dp/dq = P / 0.463
∴ MR = P * 1.463 / 0.463
= 127 * 3.16 = $401.32
since the Marginal revenue > 0 HENCE The marginal revenue will be positive when Roland sells 144 driers per week.
Answer:
a)
b)S= 46.4 cm
Explanation:
Given that
Velocity = 16 Km/s
V= 16,000 m/s
E= 27 mV/m
E=0.027 V/m
d= 22.5 cm
d= 0.225 m
a)
lets time taken by electron is t
d = V x t
0.225 = 16,000 t
b)
We know that
F = m a = E q ------------1
Mass of electron ,m
Charge on electron
So now by putting the values in equation 1
Here initial velocity u= 0 m/s
S=0.464 m
S= 46.4 cm
S is the deflection of electron.
Answer:
n/(FG) = 3.
Explanation:
<u>At the top of the loop-the-loop, the normal force is directed downwards</u> as well as the weight of the car. So, the total net force of the car is
<u>By Newton's Second Law, this force is equal to the centripetal force</u>, because the car is making circular motion in the loop.
The critical speed is the minimum speed at which the car does not fall. So, at the critical speed the normal force is zero.
If the car is moving twice the critical speed, then
Finally, the ratio of the normal force to the gravitational force is
I think the answer you are looking for is this:
t= Vf - Vi
---------
a
so plug your information as needed.
ex. 146m/s- 0m/s divided by 26.6m/s^2 = 5.50s
So 5.50s is your time
