Given:
length of the wire = 0.20 meters
magnetic field strength = 0.45 newtons/amperes meter
speed = 10.0 meters per second
emf = B * l * v
B = flux density ; l = length of the wire ; v = velocity of the conductor
emf = 0.45 newtons / ampere meter * 0.20 meters * 10.0 meters/seconds
emf = 0.90 volts
The emf produced is 0.90 volts.
Answer:
Newtons third law
Explanation:
Because it states that every force has an equal and opposite force
Answer:
The direction should be in the positive x direction.
Explanation:
Given that
Electric filed E= 410 V/m (In Negative y direction)
V= 9.1 x 10 ⁵ m/s
As we know that
F= E q + q.V x B
Given that protons is moving constant speed so ,F=0
F= E q +q. V x B
0= E + V x B
E = -V x B
- 410 j = - ( 9.1 x 10 ⁵ k x B i)
The direction should be in the positive x direction.
Answer:
option C
multiplication factor n = 1 when volume change to half and pressure become double
Explanation:
we know by Ideal Gas law:
P1V1 = nRT1
P2V2 = nRT2
according to the question
pressure is doubled and volume is reduced to half
so we have
new pressure = 2*P1
new volume = V1/2
hence,
(2P1) * (V1/2) = nRT2
P1V1 = nRT2
we have now
nRT1 = nRT2
we get
T1 = T2
thus no change in temperature
we know that internal energy is given as
internal energy = nCvT,
since temperature is directly proportional to internal energy and since temperature remains constant therefore internal energy remains constant
So there is no change in internal energy
thus, multiplication factor n = 1 when volume change to half and pressure change to double
Answer:
θ =28.07⁰
Explanation:
when van moves around an unbanked curve, horizontal component of normal force is equal to centripetal force
---(1)
There is no motion in vertical direction, so vertical component of normal force is balanced with weight of block i.e.
----(2)
divide (1) and (2)
v = 28 m/s
r = 150 m
g = 9.8m/
θ = 28.07⁰
