Answer:
F = 33.12 N
Explanation:
given,
first force = 15 N is oriented at 58.0° counterclockwise
second force = (−19.0 N,18.5 N)
x-component of first force = 15 cos 58.0° = 7.95 N
y-component of second force = 15 sin 58.0° = 12.72 N
second component
now,
F netx = 7.95 - 19 = -11.05 N
F nety = 12.72 + 18.5 = 31.22 N

F = 33.12 N

θ = -70.51°
Answer:
Animal Cells
Explanation:
they dont have cell walls because they dont need them. Wall cells are found in plants, which animals dont need.
Answer:
The circuit contains a filament bulb, connected with terminal to a terminal.
Explanation:
The base of the electric bulb and the metal tip of the base are the two terminals of the bulb. One is called a positive terminal while the other is called a negative terminal. The filament of the electric bulb is connected to its terminals.
Answer:
The power transmitted to the pulley is 0.0455 hp.
Explanation:
Given;
mass attached to the rope, m = 5 lb
radius of the pulley, r = 3 in
constant rate of fall of the mass, v = 5 ft/s
acceleration due to gravity, g = 32.2 ft/s²
1 lbf = 32.2 lb.ft/s²
The power transmitted to the pulley is calculated as;
P = Fv
P = (mg)v

in horse power, the power transmitted is calculated as;

Therefore, the power transmitted to the pulley is 0.0455 hp.
The concept of forensic entomology dates back to at least the 13th century. However, only in the last 30 years has forensic entomology been systematically explored as a feasible source for evidence in criminal investigations
