Consider a steel guitar string of initial length L=1.00 meter and cross-sectional area A=0.500 square millimeters. The Young's m

Reil [10]

Answer:

$\Delta l=0.015m$

Explanation:

We have given initial length of the steel guitar l = 1 m

Cross sectional area $A=0.5mm^2=0.5\times 10^{-6}m^2$

Young's modulus $\gamma=2\times 10^{11}Pa$

Force F = 1500 N

So stress $=\frac{force}{area}=\frac{1500}{0.5\times 10^{-6}}=3000\times 10^{-6}=3\times 10^{9}Pa$

We know that young's modulus $=\frac{stress}{strain}$

So $2\times 10^{11}=\frac{3\times 10^{9}}{strain}$

$strain=1.5\times 10^{-2}=0.015m$

Now strain $=\frac{\Delta l}{l}$

$0.015=\frac{\Delta l}{1}$

$\Delta l=0.015m$

What makes psychoanalysis different from behaviorism?

svp [43]

Psychoanalysis is a form of therapy that treats mental disorders through different ways, such as dream interpretation. It is a way of looking into the line between conscious and <span>unconsciousness </span>

Behaviorism is a theory that says that mental disorders are treated better with altering the persons behavior patterns.

I think they're different because behaviorism is just simply a theory and not actually a form of therapy.

Hopefully that helps you tell them apart!

If Juan upgrades from a sports car to a large truck, what will happen to the

vovikov84 [41]

Answer:

The force will have to increase

Explanation:

Since Juan has upgraded from a sports car to a large truck, based on Newton's second law of motion, the force needed to keep the truck going at the same speed will have to increase.

According to Newton's second law "the force on an object is equal to the product of its mass and acceleration".

Force = mass x acceleration

A truck has a larger mass compared to a sports car.

By virtue of this, to make sure both automobiles attain the same speed, the force powering them to accelerate must be the same.

Therefore, the force from the engine must increase.
