Answer:
Δt ≈ 2.9137 ≈ 3 seconds per kilometer
Explanation:
The speed of light is approximately 300000 km /s, while the speed fo the sound in the air is 0.3432 km/s.
The light takes therefore this time to travel one kilometer
On the other hand the sound takes this time to travel one kilometer
t = 2.9137 s
Then the delay time is 2.9137 -
Δt ≈ 2.9137 ≈ 3 s
Answer:
it would remain the same speed
Explanation: the rock isnt going down a hill or anything so therefore if gravity isnt pulling it down a slope then it would remain the same pace
Answer:
The relation between velocity and time is a simple one during uniformly accelerated, straight-line motion. The longer the acceleration, the greater the change in velocity. Change in velocity is directly proportional to time when acceleration is constant.

Answer:
The height of father = 178 cm.
Explanation:
The height of your father is 70 inches.
There are 2.54 centimeters in an inch
1 inch = 2.54 cm
70 inches = 70 x 2.54 = 177.8 cm
Rounding to the nearest centimeter.
70 inches = 177.8 cm = 178 cm
The height of father = 178 cm.
