The transfer of energy by electromagnetic waves is called electromagnetic radiation
speed change will not change mass, volume or density. so CORRECT ans is C. velocity
Answer:
t = 2.13 s
Explanation:
given,
height of the building = 22.3 m
horizontal distance = 127 m
acceleration due to gravity = 9.8 m/s²
time for which ball is in motion = ?
using equation of motion
initial velocity is zero
t = √4.551
t = 2.13 s
The tension on a thing is equivalent to the weight of the object x gravitational force plus/minus the mass x acceleration. But we need to transform its formula, so it will look like:2T = (160^2 +100^2)^.5
2T = (25600 + 10000) ^ 5
T =94.3398113 N or 94 N
