Answer:
13333.33 rev/min²
Explanation:
Given:
Initial angular speed of the automobile (ω₁) = 1260 rev/min
Final angular speed of the automobile (ω₂) = 3460 rev/min
Time interval for the change in speed (t) = 9.90 s
Angular acceleration of the automobile (α) = ?
Consider the sense of rotation to be positive. So, making use of the equation of motion of rotation, we have:
Rewriting in terms of 'α', we get:
Converting time 't' from seconds to minutes using conversion factor.
1 sec =
So, 9.90 s =
Plug in all the given values and solve for 'α'. This gives,
Therefore, the angular acceleration in revolutions per minute squared is 13333.33 rev/min².
Answer:
Space School is the incredible story of how astronauts train underwater to live and work in space. From micro-gravity simulation at NASA's Neutral Buoyancy Lab, to living under the sea at Aquarius Reef Base, astronauts spend a lot of time training underwater.

Answer:
P_min = 490 N/m²
P_max = 7350 N/m²
Explanation:
Formula for pressure is;
Pressure = Force/Area
We are given;
Mass = 30 kg
Dimensions of Block = 0.1 m by
0.4 m by 1.5 m.
Force(weight) = mg = 30 × 9.8 = 294 N
For minimum pressure, it will be at maximum area.
Max area will be at biggest dimensions.
Max area = 0.4 × 1.5 = 0.6 m²
P_min = 294/0.6
P_min = 490 N/m²
Similarly, maximum pressure will be at minimum area.
Minimum area = 0.1 × 0.4 = 0.04 m²
P_max = 294/0.04
P_max = 7350 N/m²
