What are your answer choices?
Weight on moon = (0.16) • Earth weight
Given:
The speed of sound is 340 m/s
Time for the echo is 5.2 s.
Let h = the depth of the canyon.
Because the sound of your voice travels to the bottom of the canyon and back to your ear, the total distance traveled is 2h.
By definition,
distance = velocity * time.
Therefore
2h = (340 m/s)*(5.2 s) = 1768 m
h = 884 m
Answer: The depth is 884 m.
Answer:
24525 N
Explanation:
The <em>mass</em> of an object is a fundamental property of the object.
The <em>weight</em> of an object is the force of gravity on the object.
This is defined as follows
Weight (W)= mass(m) × weight of a unit mass(g)
( gravitational field intensity = g)
Assuming g= 9.81 ms⁻²,
W = mg
= 2500×9.81 = 24525 N
