To solve this we assume
that the gas inside is an ideal gas. Then, we can use the ideal gas
equation which is expressed as PV = nRT. At a constant pressure and number of
moles of the gas the ratio T/V is equal to some constant. At another set of
condition of temperature, the constant is still the same. Calculations are as
follows:
T1 / V1 = T2 / V2
V2 = T2 x V1 / T1
V2 = 659.7 x 28 / 504.7

Answer:
a)
b)
c)
d)
e)
Explanation:
Given that
d = 2 cm
V = 200 V
We know that
F = E q
F = m a
E = V/d
So
m a = q .V/d b
---------1
The mass of electron
The charge on electron
Now by putting the all values in equation 1
We know that
a)
s = 0.1 cm
b)
s = 0.5 cm
c)
s = 1 cm
d)
s = 1.5 cm
e)
s = 2 cm
Answer:
Explanation:
Kinetic energy of block will be converted into heat energy by friction .
Heat energy produced = 1/2 m v²
= .5 x 4.8 x 1.2²
= 3.456 J
85% of energy is converted into heat energy , so heat energy produced
= .85 x 3.456 = 2.9376 J .
If Q heat is given to m mass of object having s as specific heat and Δt is increase in temperature
Q = msΔt
specific heat of iron s = 462 J / kg C
Putting the values ,
2.9376 = 4.8 x 462 x Δt
Δt = 13.24 x 10⁻⁴ ⁰C.
Answer: Yeast produces carbon dioxide
Explanation: Yeasts feed on the sugars in flour and releases the carbon dioxide that makes bread rise.
