Answer:
8 km/h²
Explanation:
a = v-u/t
v is final velocity, u is initial velocity
a = 40-0/5
a = 8.0 km/h²
Answer:
Interstellar Dust
Explanation:
In the solar system Interstellar dust is a type of cosmic dust and unlike Interstellar gas they have large dust particles enabling them to block visible light. Unlike smoke and fog, they contain large number of closely packed clumps of atoms and molecules
The impulse is (force) x (time) = (20 N) x (20 sec) = 400 N-sec
When we grind through the units, we find that the [newton-second]
is exactly the same as the [kilogram-meter/sec] unit-wise, and once
we know that, it doesn't surprise us to learn that impulse is equivalent
to a change in momentum (mass x speed ... also kg-m/s).
So this impulse exerted on the moving object adds 400 kg-m/s of
linear momentum to its motion, directed to the right. That may or
may not be the total change in its momentum during that 20-sec,
because our 20-N may not be the only force acting on it.
They're not hiding anywhere. They're all right there in the light that's shining into the mist.
It's just that when ALL the colors shine into your eye at the same time, your brain says "white".
I have a question: By any chance, do you have a sister Shifra ?
