Answer:
Velocity of Gulf Stream= west of north at a speed of
Explanation:
Given
- speed of ship relative to Gulf stream= west of north at a speed of 4 m/s
- speed of ship relative to earth= west of north at a speed of 4 .8 m/s
Let be the velocity of the ship relative to the earth and be the velocity of the ship with respect to the Gulf stream
Let the west direction be negative x axis and north direction be positive x axis
Now
magnitude of the velocity is given by
Let the velocity of gulf stream makes an angle with the positive y axis we have
Velocity of Gulf Stream west of north at a speed of
Answer:
shoulder
it is at the shoulder region
Explanation:
shoulder
Because that's called friction. When to things collide it causes friction which makes them stop rolling>
Answer: C. Steel
Explanation: When a sound wave travels through a solid body consisting
of an elastic material, the velocity of the wave is relatively
high. For instance, the velocity of a sound wave traveling
through steel (which is almost perfectly elastic) is about
5,060 meters per second. On the other hand, the velocity
of a sound wave traveling through an inelastic solid is
relatively low. So, for example, the velocity of a sound wave
traveling through lead (which is inelastic) is approximately
1,402 meters per second.
Answer:
Special metal hangers or stirrups called joist hangers are used when joist must be flush with the bottom of the girder or beam.
Explanation:
- A joist hanger also known as a beam hanger is a mechanical device which is used to fasten joists and rafters.
- The rafters are the carried members to beams and headers are the carrying members.
Thus, special metal hangers or stirrups called joist hangers are used when joist must be flush with the bottom of the girder or beam.
