physics major is cooking breakfast when he notices that the frictional force between the steel spatula and the Dry Steel frying

pan is only 0.200 N. Knowing the coefficient of kinetic friction between the two materials (0.3), he quickly calculates the normal force. What is it (in N)?

Answer:0.667 N

Explanation:

Given

It is noticed that Frictional Force is 0.2 N

Coefficient of kinetic Friction \mu _k=0.3

We know Friction Force is given by

f_r=\mu _k\times Normal\ reaction

therefore

0.2=\mu _k\times N

0.2=0.3\cdot N

N=\frac{0.2}{0.3}

N=0.667 N

An object weighing 49 N is pushed across a floor by a force of 12 N. What is the acceleration of the object?
NISA [10]

Answer:

Explanation:

Given parameters:

Weight of object  = 49N

Force applied = 12N

Unknown:

Acceleration of object  = ?

Solution:

The acceleration of the object is found by dividing the force by the weight;

 Acceleration  = \frac{12}{49}   = 0.25m/s²

What is 7.4 in it's simplest form?
Iteru [2.4K]
Assuming that you mean to ask <em>. . . "What is 7.4 </em><u><em>as a fraction</em></u><em> in simplest form</em>?"

7.4 = 7 and 4/10

4/10 can be reduced to 2/5

7 represents = (7*5)/5 = 35/5

so . .  7 + 4/10 = 35/5 + 2/5 = 37/5 (improper fraction in simplest form)
or
 . . . . 7 + 4/10 = 7 2/5 (mixed fraction in simplest form)
