Answer:
The number of turns in the solenoid is 230.
Explanation:
Given that,
Rate of change of current, 
Induced emf, 
Current, I = 1.5 A
Magnetic flux, 
The induced emf through the solenoid is given by :
or
........(1)
The self inductance of the solenoid is given by :
.........(2)
From equation (1) and (2) we get :
N is the number of turns in the solenoid
N = 229.28 turns
or
N = 230 turns
So, the number of turns in the solenoid is 230. Hence, this is the required solution.
Answer:
-20°C
Explanation:
The specific heat capacity of ice using the cgs system is 0.5cal/g°C
The enthalpy change is calculated as follows
ΔH=MC∅ where M represents mass C represents specific heat and ∅ represents the temperature change.
10cal = 2g×0.5cal/g°C×∅
∅=10cal/(2g×0.5cal/g°C)
∅=10°C
Final temperature= -30°C+ 10°C= -20°C

Answer:
The pressure of the tire will be 4.19 atm
Explanation:
The ideal gas equation is:
p0 * V0 / T0 = p1 * V1 / T1
Since V0 = V1 because the volume of the tire doesn't change
p0 / T0 = p1 / T1
p1 = p0 * T1 / T0
We need absolute temperatures for this equation
16 C = 289 K
45 C = 318 K
Now we replace the values:
p1 = 3.71 * 318 / 289 = 4.19 atm
Answer:
The geosphere consists of the solid Earth and the atmosphere consists of the gaseous components in the air. Thus, the answer is C.
