Answer:
"Macro Instruction"
Explanation:
A macro definition is a rule or pattern that specifies how a certain input sequence should be mapped to a replacement output sequence according to a defined procedure. The mapping process that instantiates a macro use into a specific sequence is known as macro expansion.
It is a series of commands and actions that can be stored and run whenever you need to perform the task. You can record or build a macro and then run it to automatically repeat that series of steps or actions.
Answer:
Explanation:
Let assume that changes in gravitational potential energy can be neglected. The fire hose nozzle is modelled by the Bernoulli's Principle:
The initial pressure is:
The speed at outlet is:
The initial pressure is:
Answer:
c 45 feet from the fulcrum
Explanation:
The moment at the fulcrum must be the same for each car. If the distance is d, then the artist must have ...
(2100 lb)(30 ft) = (1400 lb)(d)
2100·30/1400 ft = d = 45 ft
The Volkswagen should be 45 ft from the fulcrum.
To solve this problem we will apply the concepts related to translational torque, angular torque and the kinematic equations of angular movement with which we will find the angular displacement of the system.
Translational torque can be defined as,
Here,
F = Force
d = Distance which the force is applied
At the same time the angular torque is defined as the product between the moment of inertia and the angular acceleration, so using the previous value of the found torque, and with the moment of inertia given by the statement, we would have that the angular acceleration is
Now the angular displacement is
Here
= Initial angular velocity
t = time
Angular acceleration
= Angular displacement
Time is given as 1 minute, in seconds will be
There is not initial angular velocity, then
Replacing,
The question neglects the effect of gravitational force.
