Answer:
27000 Nm
Explanation:
The boom end at A is fixed and end at B is subjected to a 3kN force. Boom AB has length of 9m. The moment about A is the product of force 3kN (3000 N) at B and the moment arm of 9m
M = FL = 3000 * 9 = 27000 Nm
So the moment about A is 27000 Nm
Answer:
If the gas volume is decreased, the container wall area decreases and the molecule-wall collision frequency increases, both of which increase the pressure exerted by the gas. Avogadro's law. At constant pressure and temperature, the frequency and force of molecule-wall collisions are constant.
Explanation:
As the temperature increases, the average kinetic energy increases as does the velocity of the gas particles hitting the walls of the container. The force exerted by the particles per unit of area on the container is the pressure, so as the temperature increases the pressure must also increase.
Answer:
<h2>2.2 m/s²</h2>
Explanation:
The acceleration of an object given it's mass and the force acting on it can be found by using the formula
f is the force
m is the mass
From the question we have
We have the final answer as
<h3>2.2 m/s²</h3>
Hope this helps you
Answer:
- weaving of the car in motion
- Turning with a wide radius
- swerving
- Drifting from a Lane
Explanation:
The motion of a vehicle been driven by an impaired driver will be different in some ways from a vehicle driven by an unimpaired driver
and what a police officer might observe/ notice will include some of the following :
- weaving of the car in motion
- Turning with a wide radius
- swerving
- Drifting from a Lane
I believe the answer is C
