If a atom is raidoactive or unbalanced, Instability of a atom's nucleus may result form excess of either neutrons orprotons. Which means the answer is letter C
Given: Work W = 3,500 J; Force f = 250 N; Weight w = 765 N
Required: Distance d = ?
Formula: Work = force x distance or W = f x d
Distance d = W/f
d = 3,500 J/250 N
d = 14 m
The correct answer is yes, the acceleration can be zero. We know that velocity is the derivative of position and acceleration is the derivative of velocity. Therefore, we are trying to determine if there is any nonzero velocity function that we can take the derivative of to get 0. Any velocity function that is a coefficient such as v(t)=5, would have an acceleration of 0 because the derivative of a constant is always 0.
Hope this helps.
For a 650-kg satellite is in a circular orbit about Earth at a height above Earth equal to Earth’s mean radius, the resultant values are is mathematically given as
- V=5.59*10^3m/s
- T=3.98hours
- F=1.47*10^3N
<h3>What are the satellite’s orbital speed, the period of its revolution, and the gravitational force acting on it.?</h3>
Generally, the equation for satellite orbital speed is mathematically given as
a)
V=5.59*10^3m/s
b)
T=3.98hours
c)
Therefore
F=1.47*10^3N

Answer: A
Wavelength and frequency of light are closely related. The higher the frequency, the shorter the wavelength. Because all light waves move through a vacuum at the same speed, the number of wave crests passing by a given point in one second depends on the wavelength.
