Answer:

Power rating on the blender = 3809.52 Watts

Explanation:

We have expression for power equal to ratio of work and time,

Energy used by blender = Work done by electricity = 0.8 MJ = $0.8*10^6J=800000J$

Time of using blender = 3.5 minutes = 210 seconds

So power of blender = 800000/210 = 3809.52 Watts

Power rating on the blender = 3809.52 Watts

Answer:

$1.18454\times 10^{-19}\ Pa$

Explanation:

t = Time taken

u = Initial velocity

v = Final velocity

s = Displacement

a = Acceleration

m = Mass of bullet = $2.6\times 10^{23}\ kg$

r = Radius of barrel = $2.8\times 10^{23}\ m$

$v^2-u^2=2as\\\Rightarrow a=\dfrac{v^2-u^2}{2s}\\\Rightarrow a=\dfrac{370^2-0^2}{2\times 0.61}\\\Rightarrow a=112213.11475\ m/s^2$

Pressure is given by

$P=\dfrac{F}{A}\\\Rightarrow P=\dfrac{ma}{\pi r^2}\\\Rightarrow P=\dfrac{2.6\times 10^{23}\times 112213.11475}{\pi (2.8\times 10^{23})^2}\\\Rightarrow P=1.18454\times 10^{-19}\ Pa$

The pressure of the expanding gas is $1.18454\times 10^{-19}\ Pa$

Q: Explain the shape of the I-V graph of the filament lamp?

choli [55]

Answer:

initially- with positive potential differences - the current is directly proportional to the p.d. However, as the current through the filament increases, the heating effect caused in the lamp also increases and so the temperature of the filament rises. This increase in the filament's temperature also increases the resistance of the filament. As a result the rate of increase of the current decreases and a greater change in the potential difference is required to cause a change in the current. This can be seen on the curve as the gradient becomes more shallow (greater resistance). This same pattern is repeated when a negative potential difference is applied across the filament
