Answer:
2.26 s
Explanation:
The following data were obtained from the question:
Height (h) = 25 m
Acceleration due to gravity (g) = 9.8 m/s²
Time (t) =..?
The time taken for the egg to hit the floor can be obtained as illustrated below:
h = ½gt²
25 = ½ × 9.8 × t²
25 = 4.9 × t²
Divide both side by 4.9
t² = 25 / 4.9
Take the square root of both side
t = √(25 / 4.9)
t = 2.26 s
Thus, it will take 2.26 s for the egg to hit the floor.
Answer: equal to 3 m/s
Explanation:
Speed of golf ball will be equal to 3 m/s because in Perfect Elastic Collision Energy is conserved .
So speed of golf ball will be same in order to Satisfy
Initial Kinetic Energy =Final Kinetic Energy
Considering Bowling ball remains at rest after collision other wise some energy will also be acquired by bowling ball which automatically decreases the amount of Kinetic Energy of golf ball resulting its speed to decrease by some extent.
Answer:
What is the difference between quantum or nuclear physics?
How can I get the most out of Crunchbase Pro?
"Quantum physics" is an umbrella term for any field which uses the quantum formulation of the universe - I.e the postulate that observables are well defined as the eigenstates of Hermitian Operators, and all state wavefunctions obey the Schrödinger equation.
Basically all modern science uses quantum mechanics to a degree - astronomy needs it to predict the behaviour of white dwarfs, condensed matter for semiconductor behaviour and so on.
Nuclear physics is a field focussing on the internal structure and interactions of the nucleus. It lies well within the range of the quantum domain, and is 100% reliant on quantum physics to make any sensible predictions. Nuclear physics also has significant crossover with "particle physics", such that the two are quite often used interchangeably.
Nuclear Physics on the other hand, concerns itself with the particles of the nucleus called nucleons (protons & neutrons). ... In the nucleus the leading theory is quantum chromodynamics (QCD) which attempts to explain phenomena in terms of quarks which are the particles that are proposed to make up the nucleons.
Answer:
And the force of ( Attraction or repulsion) between the poles A and D ( maximum or minimum)
Answer:
6.15 s
Explanation:
The period of a simple pendulum is given by the equation
where
L is the length of the pendulum
g is the acceleration of gravity
For the pendulum in this problem,
L = 1.5 m (length)
(acceleration due to gravity on Earth)
Therefore, its period is
And therefore, the time taken for the pendulum to complete 2.5 oscillations is equal to 2.5 times the period:
