Answer:
The mass is 
Explanation:
From the question we are told that
The initial temperature is 
The final temperature is 
Generally the maximum heat produced by 1 Liter of natural gas is 
So the amount of heat produced by 100 L is
=> 
Generally given that the efficiency is 
Then actual heat received by the water is
=> 
=> 
Converting to kcal
=> 
Generally the specific heat of water is
Generally the heat received by the water is mathematically represented as
=> 
=>
Answer:
Explanation:
a )
initial velocity u = 45 m/s
acceleration a = - 5 m/s²
final velocity v = 0
v = u - at
0 = 45 - 5 t
t = 9 s
b )
s = ut - 1/2 at²
= 45 x 9 - .5 x5x 9²
405 - 202.5
202.5 m
2 )
a )
s = ut + 1/2 a t²
u = 0
s = 1/2 at²
= .5 x 9.54 x 6.5²
= 201.5 m
b )
v = u + at
= 0 + 9.54 x 6.5
= 62.01 m / s
3
a )
acceleration = (v - u) / t
= (34 - 42) / 2.4
= - 3.33 m /s²
b )
v² = u² - 2 a s
34² = 42² - 2 x 3.33² s
s = 27.41 m
c )
Average velocity
Total displacement / time
= 27.41 / 2.4
= 11.42 m /s
4 )
a )
v = u + at
v = 0 + 3 x 4
= 12 m /s
b )
s = ut + 1/2 a t²
= o + .5 x 3 x 4²
= 24 m
Initial volume of the gas (V1) = 10 inches^3
Initial pressure (P1) = 5 psi
Final pressure after compression of the gas (P1) = 10 psi
Let us assume the final volume of the gas (V2) = x
According to Boyle's Gas law, the pressure and volume of a gas remains constant under ideal condition. Then
P1V1= P2V2
5 * 10 = 10 * x
50 = 10x
x = 50/10
= 5 cubic inches
So the volume of the gas after it was compressed was 5 cubic inches. I hope the procedure is clear enough for you to understand.
Answer:
188 A
Explanation:
Parameters given:
Length of cable, L = 0.78 m
Angle, θ = 60º
Magnetic field, B = 5.5 * 10^(-5) T
Force experienced by wire, F = 7 * 10^(-3) N
The force experienced by a current carrying wire of length L, due to a magnetic field B is given as:
F = I * L * B * sinθ
=> I = F/(L * B * sinθ)
I = (7 * 10^(-3)) / (0.78 * 5.5 * 10^(-5) * sin60)
I = 188 A
