Answer:
11m/s
Explanation:
Given parameters:
Mass of the lead shot = 8kg
Energy of the shot = 484J
Unknown:
Velocity of the shot = ?
Solution:
To solve this problem, we apply the kinetic energy formula;
K.E = 
m v²
m is the mass
v is the unknown
Now, insert the parameters and solve;
484 = x 8 x v²
484 = 4v²
v² = 121
v = 11m/s
Answer:
Horizontal translation of six units
Explanation:
Moon orbits earth. it's viewable somewhere in the world every 28 days. if the place where it's viewed were by the sea, then the tidal patterns of water - high tide and low tide - could be correlated to the moon being seen or otherwise. If the moon is is visible, it presumably gives one gravitational pull on the water. If the moon is not visible, then it presumably gives a less gravitational pull. Maybe "spring" suggests a high high tide (as in growth ?) and "neap" suggests a low high tide ???
The answer is D. As the ambulance gets closer, the sound waves are compressed relative to the person; so the frequency increases.
