To determine the energy equivalent of an object, we use the famous equation of Einstein which is E=mc^2 where m is the mass of the object and c is the speed of light (3x10^8 m/s). We calculate as follows:

E = mc^2
E = 1.83 kg (3x10^8 m/s)^2
E = 1.647x10^17 J

A 53.4 kg girl is at rest on 3.55 kg skateboard. She jumps forward at 1.32 m/s. What is the velocity of the skateboard afterword
RoseWind [281]

M = mass of the girl = 53.4 kg

m = mass of skateboard = 3.55 kg

V' = velocity of the combination of girl and skateboard before she jumps forward = 0 \frac{m }{s}

V = velocity of the girl forward = 1.32 \frac{m }{s}

v = velocity of the skateboard afterward = ?

Using conservation of momentum

(M + m) V' = MV + m v

inserting the values

(53.4 + 3.55) (0) = (53.4) (1.32) + (3.55) v

v = - 19.86 \frac{m }{s}

Which one is having lesser ressistance. a 60w bulb or a 40w bulb?
Ivan
Power dissipation = (voltage across the component)² / (resistance of the component)

Since the resistance is in the denominator of the fraction in this formula for the
quantity of power dissipated, you can see that when the supply voltage is constant,
the smaller resistance dissipates more power.

So the <u>60w bulb</u> has lower resistance than the 40w bulb.

Explain Rutherford's experiment?
Ipatiy [6.2K]

Answer:

Rutherford bombarded aluminum foil with beam of light known as alpha particles. The mass of this alpha particle is equivalent to helium atom.

Explanation:

Rutherford bombarded aluminum foil with beam of light known as alpha particles. The mass of this alpha particle is equivalent to helium atom.

When this alpha particles were made to strike the aluminum foil, some passed through the foil, some were reflected and speed others changed.

The ones reflected encountered heavier particle known as the nucleus, preventing them from passing through it. The whole observations indicated that atom is not is uniformly charged sphere as proposed by J.J Thomson.

Rutherford proposed new model known as the Planetary model of atom, which described atom as containing a nucleus which is revolved by electron, just like planets revolve round the sun. And this nucleus contains opposite charge to electron which is proton, to balance the motion.

Earth's gravitational force just got three times stronger! What happens to your weight?
kicyunya [14]

Your "weight" is the name you give to that gravitational force.
So your question actually says:

           "Your weight just got three times stronger !
             What happens to your weight ?"
