A box weighing 18 N requires a force of 6.0 N to drag it at a constant rate. What is the coefficient of sliding friction?

Answers

Use f = uN to find the coefficient of friction. We know friction (6.0 N) and the normal forces (18 N), so plug them in to the equation which gives us 6 = u18. Solving for u: u = 0.33

The Correct Answer Is 0.33.

Jumpering out the resistors in a resistance-controlled three-speed fan will cause the motor toa. run at highest speed.
c. run at lowest speed.
b. run at medium speed.
d. stop immediately

Answers

The answer to the question stated above is letter a. run at highest speed.

Jumpering out the resistors in a resistance-controlled three-speed fan will cause the motor to run at highest speed. If resistors are jumpered, the three-speed fan will over speed and probably burns out.

Yes, this is because particles in a solid there are more particles which are touching. They can only vibrate. But particles in a gas are far apart. This is the same for liquids to.

Determine the volume at the equivalence point if a 0.100 M NaOH(aq) solution is used to titrate the following acidic solutions: (a) 50.0 mL of 0.200 M HBr(aq) (b) 30.0 mL of 0.150 M HNO3(aq)

Answers

Answer:

a) NaOH volume at the equivalence point is 100 ml.

b) NaOH volume at the equivalence point is 45 ml.

Explanation:

To calculate the concentration of acid, we use the equation given y neutralization reaction:

n_1M_1V_1=n_2M_2V_2

where,

n_1,M_1\text{ and }V_1 are the n-factor, molarity and volume of acid.

n_2,M_2\text{ and }V_2 are the n-factor, molarity and volume of base

a) If a 0.100 M NaOH (aq) solution is used to titrated with 50.0 mL of 0.200 M HBr(aq).

We are given:

n_1=1\nM_1=0.200M\nV_1=50.0mL\nn_2=1\nM_2=0.100M\nV_2=?mL

Putting values in above equation, we get:

1* 0.200M* 50.0 mL=1* 0.100 M* V_2\n\nV_2=100 mL

b) If a 0.100 M NaOH (aq) solution is used to titrated with 30.0 mL of 0.150 M HNO_3(aq).

We are given:

n_1=1\nM_1=0.150M\nV_1=30.0mL\nn_2=1\nM_2=0.100M\nV_2=?mL

Putting values in above equation, we get:

1* 0.150M* 30.0 mL=1* 0.100 M* V_2\n\nV_2=45 mL
