Answer: They create antibodies.
Water surface waves are examples of waves that are both longitudinal and transverse waves. As the wave travels through the water, a clockwise circles is observed. Therefore, the answer to this item is letter D. All the rest of the choices do not describe the water surface waves.
At low wind speed, more blades will be better and the blades should be long and wide. The blade pitch should be large. At high wind speed, the blades should be short and thin. The blade pitch should be small then.
Answer:
v_max = (1/6)e^-1 a
Explanation:
You have the following equation for the instantaneous speed of a particle:
(1)
To find the expression for the maximum speed in terms of the acceleration "a", you first derivative v(t) respect to time t:
(2)
where you have use the derivative of a product.
Next, you equal the expression (2) to zero in order to calculate t:
For t = 1/6 you obtain the maximum speed.
Then, you replace that value of t in the expression (1):
hence, the maximum speed is v_max = ((1/6)e^-1)a
Solids have a defined shape and liquids don't.
