Answer:
B = 191.26 cm
θ = -14.73°
Explanation:
given,
magnitude of the first displacement(A) = 146 cm
at an angle of 124°
resultant magnitude = 137 cm
and angle made with x-axis by the resultant(R) = 32.0°
component of A in X and Y direction
A x = A cos θ = 146 cos 120° = -73 cm
A y = A sin θ = 146 sin 120° = 126.4 cm
now component of resultant in x and y direction
R x = 137 cos 35°
= 112.2 cm
R y = 137 sin 35°
= 78.6 cm
resultant is the sum of two vectors
R = A + B
R x = A x + B x
B x = 112.2 - (-73) = 185.2 cm
B y = R y - A y
B y = 78.6 - 126.4 = -47.8 cm
magnitude of B
B =
B =
B = 191.26 cm
angle
θ = -14.73°
Answer:
gross and microscopic anatomy
Explanation:
Gross anatomy is the macroscopic level anatomical study and it aims to investigate macroscopic structures as well as the organization of organ systems.gross anatomy employs invasive as well as non invasive methods of study. dissection is the traditionally used method in gross anatomical study where the body of the corpse is dissected to study the organization and structure of internal organs.
Microscopic anatomical studies are conducted at the microscopic level and specialized optical instruments are used to study the tissue structures and cells.
