Definition: A command economy is where a central government makes all economic decisions. The government or a collective owns th

e land and the means of production. It doesn't rely on the laws of supply and demand that operate in a market economy. A command economy also ignores the customs that guide a traditional economy. In recent years, many of these centrally-planned economies have added aspects of the market economy.

During tug-of-war, team A does 2.20*10^5 J of work in pulling team B 8.00m. What average force did team A exert
Talja [164]

As we know that work done is defined as product of force and displacement

so here we will have

W = F.d

so here we know that

W = 2.20 \times 10^5 J

also we know that

d = 8.00 m

now we will have

2.20 \times 10^5 = F(8.00)

F = \frac{2.20 \times 10^5}{8}

F = 27500 N

so it will have 27500 N force on it

Big Bee has a mass of 5 kg and hits a newly cleaned windshield accelerating at a rate of 2 m/s2.
Juli2301 [7.4K]

Answer

The Little Bee will have a greater force of  12N

<u>Explanation</u>

As we know that Force  is equal to the product of mass and acceleration (F=ma)

The Force with which the Big Bee will hit the windshield =  (5kg x 2m/s^2)

Force of Big Bee= 10 Newton (N)

The Force with which the Little Bee will hit the windshield = (3kg x 4m/s^2)

Force of Little Bee = 12N

Hence, the little bee will hit the windshield with a greater force.

By what factor must we increase the amplitude of vibration of an object at the end of a spring in order to double its maximum sp
strojnjashka [21]

Answer:

A'=2A

Explanation:

According to the law of conservation of energy, the total energy of the system can be expresed as the sum of the potential energy and kinetic energy:

E=U+K=\frac{kA^2}{2}\\E=\frac{kx^2}{2}+\frac{mv^2}{2}=\frac{kA^2}{2}

When the spring is in its equilibrium position, that is x=0, the object speed its maximum. So, we have:

\frac{k(0)^2}{2}+\frac{mv_{max}^2}{2}=\frac{kA^2}{2}\\A^2=\frac{mv_{max}^2}{k}\\A=\sqrt{\frac{mv_{max}^2}{k}}

In order to double its maximum speed, that is v'{max}=2v_{max}. We have:

A'=\sqrt{\frac{m(v'_{max})^2}{k}}\\A'=\sqrt{\frac{m(2v_{max})^2}{k}}\\A'=\sqrt{\frac{4mv_{max}^2}{k}}\\A'=2\sqrt{\frac{mv_{max}^2}{k}}\\A'=2A
