Answer:
Δ v = 125 m/s
Explanation:
given,
mass of space craft = 435 Kg
thrust = 0.09 N
time = 1 week
= 7 x 24 x 60 x 60 s
change in speed of craft = ?
Assuming no external force is exerted on the space craft
now,
a = 2.068 x 10⁻⁴ m/s²
using equation of motion
Δ v = a t
Δ v = 2.068 x 10⁻⁴ x 7 x 24 x 60 x 60
Δ v = 125 m/s
Answer:
Wavelength of light and frequency have inverse relationship.
Explanation:
Wavelength of light and frequency have inverse relationship. This is because Wave length is the distance between two successive crests or troughs while frequency is the number of waves passing through a specific point in one second.
It is cleared if the wavelength is larger less numbers of waves will pass through a given point and vice versa.
Answer: The variable that you manipulate is called the independent variable. The variable that you measure is called the dependent variable.
So far, I have not been able to run a mile in under 30 minutes.
That proves that I can't do it, but <span>that does not necessarily mean
its impossible. It </span>doesn't prove that nobody else can do it.
Nobody and nothing has ever traveled faster than the speed of light.
That doesn't prove that somebody or something that hasn't tried yet
can't do it. But discoveries in Physics, Quantum Mechanics, Cosmology,
and Relativity, over roughly the past 125 years, which explain and predict
almost everything seen in hundreds of experiments and thousands of
observations since then, do all agree that the speed of light is, let's say,
nature's "speed limit", and that no matter how hard you try, nothing and
nobody CAN travel faster.
If energy input remains
constant and voltage remains the same in a circuit, but the current decreases,
the power has increased. It is presented in the equation P = VI where P is
power, V is voltage and I is current.
