Why is friction useful between your feet and the groud?

Friction is useful between your feet and the ground because friction is the same force that allows you to accelerate forward when you run.

Friction refers to the resistance that one surface or object encounters when moving over another. Friction is the rubbing of one body against another the friction of sandpaper on wood.

Answer:

It allows you to walk faster.

Explanation:

It is the same force that allows you to accelerate forward when you run. Your planted foot can grip the ground and push backward, which causes the ground to push forward on your foot. We call this grip type of friction, where the surfaces are prevented from slipping across each other, a static frictional force.

Yuki888 [10]

Answer:

Cost = 40 fills

Explanation:

First, we will calculate the total power consumed by all appliances:

$Power = P_{TV}+P_{heater}+P_{lamp}\\Power = 250\ W+1150\ W+200\ W\\Power = 1600\ W = 1.6\ KW$

Now, we will calculate the energy required:

$Energy = (Power)(Time)\\Energy = (1.6\ KW)(2.5 h)\\Energy = 4 KWh\\$

Now, for the cost we use the following formula:

$Cost = (Energy)(Unit\ Cost)\\Cost = (4\ KWh)(10\ fills/KWh)\\$

<u>Cost = 40 fills</u>
