Answer:
for abt 36 seconds
Explanation: cuz thats how long it was
To get the speed of light in this class glass, used the following equation
v= c/n ; where c is the speed of light in a vacuum and n where the index of refraction
Based on my research the index of refraction of the class glass is 1.59
Given
c= 3.00 x 10^8 m/s
n= 1.59
Solution
we will use 3.00 for c to get the speed of light in class glass cause 10^8 m/s is fixed
v= 3.00 / 1.59
v= 1.886
So the speed of light in this class glass is 1.89 x 10^8 m/s
The amount of energy needed to raise the temperature of 250 g of water from 20 to 100 degree Celsius is
Q = 250 (4.18) (100 - 20)
Q = 83600 J
The power delivered is
P = 83600 / (4(60))
P = 348.33 W
According to the data for a Nichrome wire, the wire gauge for power rating of 348.33 W and 120 V power supply is
23-27 AWG
Answer:
Explanation:
= Vacuum permeability =
= Radius of loop = 15 cm
= Current in loop = 11 A
= Radius of coil = 0.76 cm
N = Number of turns of coil = 66
= Current in coil = 1.9 A
Magnetic field is given by
Magnitude of magnetic field produced by the loop at its center is .
Torque is given by
Magnitude of torque on the coil due to the loop is
Answer:
vf=94.4 m/s
Explanation:
acceleration is the final velocity minus initial velocity divided by time
a = (vf-vi)/t
Given:
a= 14.2 m/s^2
vi= 0 (at rest)
t = 6.6
Solve for vf
a = (vf-vi)/t
a*t=vf-vi
(14.2)*(6.6)=vf - 0
vf=94.4 m/s
