Answer:
2.667m/s to the north and 3.333 m/s to the west
Explanation:
According to law of momentum conservation, the total momentum should be conserved before and after the explosion.
Before the explosion, the momentum was
0.5*2 = 1 kg m/s to the west
Therefore the total momentum after the explosion should be the same horizontally and vertically.
Vertically speaking, it was 0 before the explosion. After the explosion:
0.2*4 + 0.3v = 0
0.3v = -0.8
v = -0.8/0.3 = -2.667 m/s
So the vertical component of the 0.3kg piece is 2.667m/s to the north
Horizontally speaking, since the 0.2kg-piece doesn't move west or east post-explosion:
0.2*0 + 0.3V = 1
0.3V = 1
V = 1/0.3 = 3.333 m/s
So the horizontal component of the 0.3kg piece is 3.333 m/s to the west
Answer:
1 kg lead to earth is greater attraction as mass of earth is much more than 1kg lead.
Explanation:
Objects with more mass have more gravity. Gravity also gets weaker with distance. So, the closer objects are to each other, the stronger their gravitational pull is. Earth's gravity comes from all its mass
Answer: Think of it like this, in space there is no gravity. This makes it very hard to move. This is why spacesuits have mini propellers. And the reason why rockets well... have rockets.
A good example that will help to to tell mike what 37°c feels like is body temperature.
<h3>What is room temprrature?</h3>
The average room temperature is typically around 20°C, or 68 degrees Fahrenheit.
<h3>What is body temperature?</h3>
The average body temperature is 98.6 Fahrenheit or 37 degrees Celsius.
Thus, a good example that will help to to tell mike what 37°c feels like is body temperature.
