Answer:
22.27 m
Explanation:
initial velocity, u = 25 m/s
Angle of projection, θ = 45°
height, h = 30 m
Let t be the time taken to reach the ground.
use second equation of motion in vertical direction
t = 1.26 second
The horizontal distance = horizontal velocity x time
d = 25 Cos 45 x 1.26 = 22.27 m
C, the runner moved with constant velocity for 2 seconds before decreasing in speed and running with constant velocity for another 2 seconds
Answer:
1J
Explanation:
Work done = force × distance
1 × 1 = 1
Work done = 1J
J = Joules
Hello, I don't see a table, but I am guessing that you are referring to the one I attached (below).
Answer:
So, the correct order of events sorted chronologically is:
<u>
1. A nebula located in the Milky Way galaxy begins pulling nearby hydrogen atoms in its orbit.
</u>
2. The Nebula shrinks in its volume due to gravity, becoming denser and hotter. But, it's not hot enough for nuclear fusion.
<u>
3. The temperature in the core of the Nebula reaches 14 million Kelvin.
</u>
4. Hydrogen atoms begin shedding their electrons and colliding with one another.
5. The Sun enters the main sequence stage. The energy created as a result of its radiation begins nurturing life on planet such as Earth.
6. The Sun uses up all the hydrogen in its core.
<u>
7. The Sun expands greatly and cools. It is larger and redder.
</u>
8. The Sun completely runs out of hydrogen to fuse. Its outer layers are pushed away, and a cloud of ionized gas surrounds its core.
<u>
9. The Sun is a white dwarf with a dim glow.</u>
Hope this helps!
