<span>the speed of something in a given direction. so i think none of these</span>
<span>436 km
The conversion factor between kilocalorie/hour and watts is 1.163 (1 kcal/hr = 1.163 watt). So let's convert the energy consumption of the bird from watts to kcal/hr
3.7 w / 1.163 w hr/kcal = 3.18 kcal /hr
1 gram of fat has 9 kcal, so the total number of kcals consumed will be 4 * 9 = 36.
So the bird can fly for 36/3.18 = 11.32 hours
The distance traveled will be
11.32 h * 3600 s/h * 10.7 m/s / 1000 m/km = 436 km</span>
Answer:
0.9904 m/s
Explanation:
To solve this problem we need to use the conservation of momentum:
m1v1 + m2v2 = m1'v1' + m2'v2'
Using this equation, we have:
m_bullet*v_bullet = m_bullet_after*v_bullet_after + m_block*v_block
0.00425 * 375 = 0.00425 * 114 + 1.12 * v_block
1.12 * v_block = 1.5938 - 0.4845
1.12 * v_block = 1.1093
v_block = 1.1093 / 1.12
v_block = 0.9904 m/s
Mass: the amount of matter an object contains
Weight: mass•acceleration due to gravity(9.8m/s) / the force of gravity acting on an object
Answer:
Explanation:
Pluto is a dwarf planet that lies in the Kuiper Belt, an area full of icy bodies and other dwarf planets out past Neptune. Pluto is very small, only about half the width of the United States and its biggest moon Charon is about half the size of Pluto
