When operated on a household 110.0-V line, typical hair dryers draw about 1650 W of power. We can model the current as a long st
defon

Answer:

Current in the hair dryer will be equal to 15 A

Explanation:

We have given that household is operated at 110 volt

So potential difference V =110 volt

Power drawn by hairdryer is P = 1650 watt

We have to find the current in the hair dryer

We know that power is given as P = VI, here V is potential difference and I is current

So 1650=110\times I

I = 15 A

So current in the hair dryer will be equal to 15 A

A branch falls from a tree how fast is the branch moving after drug .28 seconds
alexdok [17]
Acceleration=9.81m/s^2
initial velocity=0m/s
time=.28s

We have to find final velocity.

The equation we use is

Final velocity=initial velocity+acceleration x time

Vf=0m/s+(9.81m/s^2)(.28s)
Vf=2.7468m/s

We would round this to:

Vf (final velocity)=2.7m/s

In a women's 100-m race, accelerating uniformly, laura takes 1.96 s and healan 3.11 s to attain their maximum speeds, which they
liubo4ka [24]
First we write the kinematic equations
 a
 v = a * t + vo
 r = (1/2) at ^ 2 + vo * t + ro
 We have then that:
 (10.4 - t) = time that they run at their maximum speed
 For Laura:
 d = (1/2) at ^ 2 + (at) (10.4 - t)
 100 m = (1/2) a (1.96) ^ 2 + [(1.96) a] (8.44)
 100 = 1.9208a + 16.5424a
 100 = 18.4632a
 a = 100 / 18.4632 = 5.42 m / s ^ 2
 For Healen:
 100 = (1/2) a (3.11) ^ 2 + [(3.11) a] (7.29)
 100 = 4.83605a + 22.6719a
 100 = 27.50795a
 a = 100 / 27.50795
 a = 3.64 m / s ^ 2
 Answer:
 the acceleration of each sprinter is
 Laura: 5.42 m / s ^ 2
 Healen 3.64 m / s ^ 2
