Answer:
A
Explanation:
to simplify let's make it apart the denominator into three part
now let's simplify
so the answer is A
hope it helps
for any question comment me ❤❤
In a nuclear decay, an unstable atom releases energy or particles to reach a more stable state. The energy released is equivalent to the difference between the mass of the original atom and the resultant atom and particles.
The events involved in the decay arranged in order to describe the process:
1. The nucleus is unstable.
2. The nucleus start to fall apart.
3. Radiation, mass, and energy are released.
4. The nucleus is stable.
Momentum is P=mass*velocity
Be that it may the real car and toy car travel at the same velocity, the real car has a much larger mass. Since Momentum is directly proportional to mass, the real cars momentum is therefore larger.
Just so you know people aren’t replying because the bar graph isn’t show :/
Answer:
a) s
b) 3.41 mm
Explanation:
a)
We take the speed of light, c = m/s and the refractive index of glass as 1.517.
Speed = distance/time
Time = distance/speed
Refractive index, n = speed of light in vacuum / speed of light in medium
b)
We take the refractive index of water as 1.333.
Speed in water = speed in vacuum / refractive index of water
Distance = speed * time
d = 3.41 mm
