Answer:

The ocean surface currents are mainly generated due to the wind that blows over the ocean and density differences in the water. In simple words, these surface currents are formed due to the global wind systems that are facilitated by the energy from the sun.

There are various factors that control the pattern of surface currents in the oceans, which include the Coriolis force, the prevailing wind blowing direction, and also the location of various types of landforms near the ocean bodies that continuously interact the water currents.

Thus, the sun is the most common source of energy for the creation of surface currents.

Explanation:

V=40m/s

Vy=V.sina=40.sin20=40 . 0.342=13.68m/s

Vx=V.cosa=40.cos20=40 . 0.766=30.64m/s

A shell is fired at an angle of 35° above the horizontal at a velocity of 40 m/s. (a) What is it's speed at the highest point of

Fudgin [204]

Answer:

Part a)

$v_f = v_x = 32.77 m/s$

Part b)

T = 4.68 s

Explanation:

Part a)

Shell is fired at speed of 40 m/s at angle of 35 degree

so here we have

$v_x = 40 cos35 = 32.77 m/s$

$v_y = 40 sin35 = 22.94 m/s$

since gravity act opposite to vertical speed of the shell so at the highest point of its trajectory the vertical component of the speed will become zero

so at the highest point the speed is given

$v_f = 32.77 m/s$
