Andrei [34K]

Answer:

Globalized economy.

Explanation:

The world economy is a global economic system made up of economies of countries that are more or less interconnected. One of the key words in the world economy is globalization, which means that national economies are so closely interlinked that events in one country usually affect the economies of other countries. Globalization has become particularly dominant over the last century. More and more trade is taking place between different countries, and restrictions on this have been significantly reduced. The result is a global economic phenomenon. People can sell goods and services in markets around the world, and consumers can choose from a much wider range of goods and services. It no longer has to be limited to what is offered in one's own country.

Lesechka [4]

Answer:

The heat transferred to water equals 1600 kJ

Explanation:

By the conservation of energy we have

All the kinetic energy of the moving vehicle is converted into thermal energy

We know that kinetic energy of a object of mass 'm' moving with a speed of 'v' is given by

K.E=\frac{1}{2}mv^{2}

Thus

K.E_{car}=\frac{1}{2}\times 2000\times 40^{2}=1600\times 10^{3}Joules

Thus the heat transferred to water equals 1600kJ

Steel bar A of 5 mm diameter is subject to a stress of 500 MPa. Aluminum bar B of 10 mm diameter is subject to a stress of 150 M
weqwewe [10]

Answer:

aluminum bar carrying a higher load than steel bar

Explanation:

Given data;

steel abr

diameter = 5 mm

stress = 500 MPa

aluminium bar

diameter = 10 mm

stress = 150 MPa

we know

stress = laod/area

for steel bar

500 = \frac{P}{\frac{\pi}{4} 5^2}

solving for P

P = 9817.47 N

for Aluminium bar

150 = \frac{P}{\frac{\pi}{4} 10^2}

solving for P

P = 11790 N

aluminum bar carrying a higher load than steel bar
