Part one: a gust of wind blows an apple from a tree.

as the apple falls, the force of gravity on the

apple is 9.39 n downward, and the force of

the wind on the apple is 1.50 n to the right.

what is the magnitude of the net external

force on the apple?

answer in units of n.

part two: what is the direction of the net external force

on the apple (measured from the downward

vertical, so that the angle to the right of

downward is positive)?

answer in units of ◦

The a992 steel rod bc has a diameter of 50 mm and is used as a strut to support the beam. determine the maximum intensity w of the uniform distributed load that can be applied to the beam without risk of causing the strut to buckle. take f. s. = 2 against bucklin

The magnitude of the magnetic field at a certain distance from a long, straight conductor is represented by b. what is the magnitude of the magnetic field at twice the distance from the conductor? a. at twice the distance, the magnitude of the field is 4b. b. at twice the distance, the magnitude of the field is 2b. c. at twice the distance, the magnitude of the field is b/2.d. at twice the distance, the magnitude of the field is b/4.e. at twice the distance, the magnitude of the field remains equal to b.
