The bomb strike the ground relative to the point at 1km . B
<h3>How to determine the distance</h3>
Using the equation
h = 1/2 gt^2
500 = 1/2 * 10* t^2
500 = 5t^2
t = √500/5
t = √100
t = 10seconds
To find the distance,
Distance = velocity * time
Distance = 100 ÷ 10
Distance = 1000m = 1km
Therefore, the bomb strike the ground relative to the point at 1km . B

Answer: Pulsars</h2>
A <u>pulsar</u> is a neutron star that emits very intense electromagnetic radiation at short and periodic intervals ( rotating really fast) due to its intense magnetic field that induces this emission.
Nevertheless, it is important to note that all pulsars are neutron stars, but not all neutron stars are pulsars.
Let's clarify:
A neutron star, is the name given to the remains of a supernova. In itself it is the result of the gravitational collapse of a massive supergiant star after exhausting the fuel in its core.
Neutron stars have a small size for their very high density and they rotate at a huge speed.
However, the way to know that a pulsar is a neutron star is because of its high rotating speed.
7). Stopping is an acceleration.
2nd law . . . . . f = m a
Bigger mass needs more force.
Bowling ball has more mass than a golf ball.
9). 2nd law . . . . . f = m a
It doesn't say anything about where the force comes from,
only the size of the force. A child, dog, bird, adult, or
tow-truck have to use the same amount of force to produce
the same result.
10). 2nd law . . . . . f = m a
More acceleration requires more force.
Answer:
Explanation:
a ) Current remains the same throughout the whole of a closed circuit if all the resistances are in series. So current will remain the same in both these conductors as they are in series.
b ) If the two wires are switched or exchanged mutually , there will not be any change in the current are they will still remain in series and total resistance remains the same . so current will remain the same . Hence the current through the bulb will remain unchanged . The brightness too will remain the same.
No. 3( NO) is the molecule
