Answer:
Newton's third law: If an object A exerts a force on object B, then object B must exert a force of equal magnitude and opposite direction back on object A. This law represents a certain symmetry in nature: forces always occur in pairs, and one body cannot exert a force on another without experiencing a force itself.
Explanation:
The hailstone will hit the earth in 4.04 seconds.
we move 9.8 meters per second faster thanks to gravity. we start to fall after one second at 9.8 m/s. we start falling at 19.6 m/s after two seconds, and so forth.
From the query, the following information may be deduced:
Height (H) = 120 m
Gravitational acceleration (g)=9.8 m/s2.
Time (t)=?
It is possible to determine the hailstone's impact time as:
h=1/2 gt²
120= 1/2 x 9.8 x t²
120x2/9.8=t²
t²=24.48
t=4.94 s
therefore, the calculated time taken is 4.94 s.

Answer:
B. 1.55 × 10³ m/s
Explanation:
f = 3.02 x 10^6 Hz
wavelength = 5.13 x 10^-4 m
v = ?
v = f*lamda
v = 3.02 x 10^6 × 5.13 x 10^-4
v = 1.55 × 10³ m/s
C should be the right answer! hopefully this helps!
