Answer:
D. 2
Explanation:
The skydiver will reach terminal velocity when gravity = air resistance. When this occurs, he/she will no longer accelerate and his/her speed will be constant.
Once the skydiver opens the parachute, his/her speed will decrease suddenly, and again the air resistance increases due to the parachute's large area. Eventually, gravity will equal air resistance again and terminal velocity will be reached for the second time.
Even though the speeds are different, the first terminal velocity is much higher than the second one, this question refers to how many times terminal velocity is reached, not how many times the skydiver accelerates.
answer- 2.3
km/hr 120/1 276/h 276/2.3
Two components (vertical and horizontal)
Most of the geologic activity happens
at the boundaries between tectonic plates where two plates meet. This activity
occurs as plates interact, such as volcanoes, earthquakes, and mountain building. Geographies that form
at a plate boundary are determine by the direction of plate motion and by the
type of crust at the boundary.
Moreover, plate boundaries has three types namely;
divergent plate boundaries where the two plates move away from each other, then
convergent plate boundaries, here the two plates move towards each other and
lastly, transform plate boundaries, in which the two plates slip past each
other.
