If an irregularly shaped object (such as a wrench) is dropped from rest in a classroom and feels no air resistance, it will If a

n irregularly shaped object (such as a wrench) is dropped from rest in a classroom and feels no air resistance, it will accelerate and turn about its center of gravity with uniform angular speed. accelerate and turn about its center of gravity with uniform angular acceleration. accelerate and turn until its center of gravity reaches its lowest point. accelerate and spin until its center of gravity reaches its highest point. accelerate but will not spin.

Answer:

It accelerate but will not spin.

Explanation:

If an irregular shaped object is dropped from rest without feeling any form of air resistance it will accelerate without spinning and this is due to the fact that there is no Torque around  the center of gravity

KATRIN_1 [288]

Full Question:

Consider an automobile with a mass of 5510 lbm braking to a stop from a speed of 60.0 mph.

How much energy (Btu) is dissipated as heat by the friction of the braking process?

______Entry field with incorrect answer Btu

Suppose that throughout the United States, 350.0 x 10^6 such braking processes occur in the course of a given day.   Calculate the average rate (megawatts) at which energy is being dissipated by the resulting friction.

______Entry field with incorrect answer MW

Answer:

Energy dissipated as heat = 852.10 Btu

Average rate of energy dissipation = 3.64 MW

Explanation:

1 lb = 0.453592 Kg

Mass = 5510 lb = 0.453592 * 5510 Kg = 2499.29 Kg

1 mph = 0.44704 m/s

Velocity = 60 mph = 60 * 0.44704 m/s = 26.82 m/s

Let E be equal to energy acquired

E = 1/2 MV^{2}

E = 0.5 * 2499.29 * 26.88^{2} \\E = 899.01 * 10^{3} Joules

Energy dissipated as heat:

E= 8.99*10^{3} = 0.0009478 * 8.99*10^{3}\\E = 852.10 tu

E = 852.10 Btu

Energy dissipated throughout the United States

E = 350 * 10^{6} * 899.01 *10^{3} \\E=3.1466 * 10^1^4 Joules\\

Average power rate in MW, P

P = (3.1466*10^{14} )/(24*60*60)\\P=3.64*10^{9} \\P=3.64MW

People, such as pilots, who have to move quickly from lighted surroundings to night
sergey [27]

Answer:

the rods are insensitive to red light.​

Explanation:

People, such as pilots, who have to move quickly from lighted surroundings to night darkness use red light illumination because human eye is less sensitive to longer wavelength ( rhodopsin in rods cells of eye).Using red goggles,the cones can receive enough light to provide photopic vision. Whereas rods are less sensitive to longer wavelength (red light).So, the crew members remains dark adopted.

Hence, (d) is the correct answer.

Density problems brainless anwser to first person who does it
Aleks04 [339]

<u>First question:</u>

Density = \frac{mass}{volume}

Mass = density × volume

The density of the cube is 1.2g/cm³

The volume of the cube is given by side × side × side:

Volume = 7cm × 7cm × 7cm = 347cm³

Mass = 1.2g/cm³ × 343cm³ = 411.6g

*Hint: Just apply the formula Density = \frac{mass}{volume} to solve the next questions.
