A crate of fragile dishes is in the back of a pickup truck. The truck accelerates north from a stop sign, and the crate moves without slipping.

Does the friction force on the crate point north or south?

Or is the friction force zero?

Explain in complete sentences.

Answer and Explanation:

As the truck accelerates towards north, the crate in the back of the pickup truck is accelerated towards south without slipping but the friction force between the bottom of the crate and the surface of truck is along the direction of the truck and thus the direction of truck is north so the fiction force also would be along north.

HELP

As the truck accelerates towards north, the crate will experience a force towards south, thus accelerating it (crate) due south. The force of friction between the crate and truck floor will thus act towards north direction to oppose the motion of the crate.

-first use of geothermal energy occurred more than 10,000 years ago in north america by american paleo-indians

-the first industrial use of geothermal energy began near pisa, italy in late 18th century

-in 1904, italian scientist piero ginori conti invented the first geothermal electric power plant in which steam was used to generate the power

-with the above experiment, the first geothermal plant in usa started in 1922 with a capacity of 250 kilowatts

-however, in 1946 first ground-source geothermal heat pump installed at commonwealth building in portland, oregon

-during the 1960’s, pacific gas and electric began operation of first large scale geothermal power plant in san francisco, producing 11 megawatts

-in 1973, when oil crisis began many countries began looking for renewable energy sources and by 1980’s geothermal heat pumps (ghp) started gaining popularity in order to reduce heating and cooling costs

-as effect of climate change started showing results, governments of various countries joined hands to fight against it, for which kyoto protocol was signed in japan in 1997, laid out emission targets for rich countries and required that they transfer funds and technology to developing countries, 184 countries have ratified it

hope this
