Answer:
Explanation:
1) Displacement of the object will be gotten using simply adding the distances since they are goinf in the same direction (positive y direction)
Displacement= 330km + 220km
Displacement = 550km North
2) For a falling body, the body will possess positive acceleration due to gravity because it is falling under the influence of gravitational force. If a body is not under the influence of gravity and is thrown up, such body wont come back down. Hence the value of acceleration due to gravity of a body falling to the ground is +9.8 m/s² (note that the unit of acceleration is m/s²)
Correct me if I’m wrong but I think it’s C
Conductors transfer energy (metal is a good one) and insulators stop the transfer of energy (such as rubber or plastic). Sorry if that is wrong, but I hope it helps!
Answer:
18.94 m/s
Explanation:
The bat becomes the source of sound . Source is moving towards observer
apparent frequency = actual frequency x (V / V - V_s)
V is velocity of sound and V_s is velocity of source or bat.
apparent frequency / actual frequency = V / (V - V_s)
21 / 12 = 340 / (340 - V_s)
1.059(340 - V_s) = 340
340 x .059 = 1.059 V_s
V_s = 18.94 m/s

Answer:
1. What was the diameter of the hailstone in inches_5.09_ and in cm___12.92___ and in feet ____0.42___?
2. What was the total volume of the hailstone in cubic inches___68.64___ and cubic feet____0.03____?
3. What was the fall velocity of this hailstone in m/s_____2.584____ and in mph___5.78_____?
Explanation:
1. If the circumference (L) of the stone is 16 inches, then from the following equation
1 inch = 2.54 cm = 0.08 ft, so 5.09 inches = 12..92 cm = 0.42 ft
2. The total volume is
3. The fall velocity is V = kd, where k = 20 if d is in cm. Let's calculate the fall velocity in cm.
2.584 m/s = 5.78 mph
