A ball of mass 8 kg falls from rest from a height of 100 m. Neglecting air resistance,calculate its kinetic energy after falling
astra-53 [7]
As an object falls from rest, its gravitational energy is converted to kinetic energy

G.P.E = K.E = mgh

K.E = (80 Kg)(9.8 m/s²)(30 m)

K.E. = 23,520 J

What is the resistance of a bulb of 4ow<br>connected in a line of 220v?<br>2​
inn [45]

Answer:

1210 ohm

Explanation:

Given :

P=40 W

V=220 V

Now,

P=\frac{V^{2} }{R} \\40=\frac{(220)^{2} }{R} \\40R=48400\\R=\frac{48400}{40} \\R=1210 ohm

Therefore, resistance of bulb will be 1210 ohm

A muon is traveling at 0.988
AlexFokin [52]

As per Einstein's relation of relativity

m = \frac{m_0}{\sqrt{1 - \frac{v^2}{c^2}}}

here we know that

m_0 = 207 m_e = 207 \times 9.11 \times 10^{-31} kg

m_0 = 1.88 \times 10^{-28} kg

now here we know that

v = 0.988 c

now from above equation mass of the muon is given as

m = \frac{1.88 \times 10^{-28}}{\sqrt{1 - 0.988^2}}

m = 1.22 \times 10^{-27} kg

now for the momentum of muon we can use

P = mv

P = 1.22 \times 10^{-27} \times 0.988(3 \times 10^8)

P = 3.62 \times 10^{-19} kg m/s

so above is the momentum of muon
