Answer:
a. 37.75°
b. 6.21 m
Explanation:
a. The horizontal force acting on a pendulum bob is given as:
F = mgsinθ
where m = mass of bob
g = acceleration due to gravity
θ = angle string makes with the vertical or angle of displacement
Making θ subject of formula, we have:
θ = 
θ = 
θ = 37.75°
The maximum angle of displacement is 37.75°
b. Period of a pendulum is given as:

where L = length of string
Therefore, making L subject of formula:


The string holding the pendulum has to be 6.21 m long.
Answer: b
Explanation: the two pieces will repel as both have obtained a static charge.
Answer:
v = 418.31 m/s
Explanation:
given,
Radius of earth = 6400 Km
latitude at Miami, Florida = 26°
first we have to find the radius of the rotation at that latitude.
radius = 6400 x 1000 x cos 26°
circumference will be equal to = 2 π r
cos θ is used because at equator angle is zero radius is maximum and cos θ is maximum at 0°
calculation of time to
time = 24 hr
t = 24 x 60 x 60 = 86400 s


v = 418.31 m/s
speed of a physics student in Miami, Florida is equal to v = 418.31 m/s
Larry, a 10-year-old, first sees two identical glasses with water at the same level;then, the water from one of the short, wide glasses is poured into a taller, thinner glass.Larry will likely conclude that <span>a. there is more water in the taller, thinner glass</span>
