The relationship between the mass of the celestial bodies relative strengths is that the bigger the planet the more gravity pulls you down for example compare Earth with a human, if a person jumps gravity pulls you down compare it to REAL LIFE you see how fast and hard you land but on Pluto or Mercury, there is no gravity just like on the moon that's why when see people on the moon jump, they seem to float. So the more mass or how much a planet can hold gravity brings you down faster and stronger than regular.
The velocity of light is v = 3 x 10⁸ m/s.
The given wavelength is λ = 0.86 nm = 0.86 x 10⁻⁹ m.
Note that
v = fλ
where f = frequency.
Therefore
f = (3 x 10⁸ m/s)/(0.86 x 10⁻⁹ m)
= 3.488 x 10¹⁴ Hz
Answer: 3.49 x 10¹⁴ Hz
Answer:
12J
Explanation:
Given parameters:
Mass = 1.5kg
Impulse = 6kgm/s
let us start first by find the velocity with which this body moves;
Impulse = mass x velocity
Velocity = Impulse / mass = 6/ 1.5 = 4m/s
Initial velocity = 0m/s
Unknown:
Resulting kinetic energy = ?
Solution:
To solve this problem use the formula below:
K.E = m (v - u)²
m is the mass
v is the final velocity
u is the initial velocity
So;
K.E = x 1.5 x (4 - 0)²
K.E = 1.5 x 8 = 12J
Neutrons are responsible for a nuclear fission chain reaction.
An electric current produces a magnetic field when the current flows through a wire. The correct answer will be A.
