vinegar has the most amount of hydroxide atoms.

A base is a substance that accepts hydrogen ions. When a base is dissolved in water, the balance between hydrogen ions and hydroxide ions shifts the opposite way.

A 9-μC positive point charge is located at the origin and a 6 μC positive point charge is located at x = 0.00 m, y = 1.0 m. Find
sukhopar [10]

Answer:

The coordinates of the point is (0,0.55).

Explanation:

Given that,

First charge q_{1}=9\times10^{-6}\ C at origin

Second charge q_{2}=6\times10^{-6}\ C

Second charge at point P = (0,1)

We assume that,

The net electric field between the charges is zero at mid point.

Using formula of electric field

E=\dfrac{kq}{r^2}

0=\dfrac{k\times9\times10^{-6}}{d^2}+\dfrac{k\times6\times10^{-6}}{(1-d)^2}

\dfrac{(1-d)}{d}=\sqrt{\dfrac{6}{9}}

\dfrac{1}{d}=\dfrac{\sqrt{6}}{3}+1

\dfrac{1}{d}=1.82

d=\dfrac{1}{1.82}

d=0.55\ m

Hence, The coordinates of the point is (0,0.55).

A man in a lift is moving upwards in a constant speed.the weight of the man is W.Acc
Nookie1986 [14]

Answer:

Normal force=mg

Explanation:

The reaction force of weight is the normal force.

in order to find the normal for we need to write all the forces and set it equal to the net force:

N-mg=ma (since it is a constant speed the a=0)

N=mg

A supersonic airplane is flying horizontally at a speed of 2650 km/h. What is the centripetal acceleration of the airplane, if i
Andrew [12]

Answer:

a_{c}=82617.65km/h^{2}\\  or\\a_{c}=6.37m/s^{2}

Explanation:

Given data

Speed v=2650 km/h

Radius r=85.0 km

To find

Centripetal Acceleration

Solution

As centripetal acceleration is given as

a_{c}=\frac{v^{2} }{r}................eq(i)

where

v is velocity

r is the radius

Substitute the given values in eq(i)

a_{c}=\frac{(2650km/h)^{2} }{85km} \\a_{c}=82617.65km/h^{2}\\  or\\a_{c}=6.37m/s^{2}

In a random sample of 200 students from Northern State University, 150 said that they own an Therefore, probably at least 50% of
kirza4 [7]

Answer:

No fallacy

Explanation:

The statement that at least  50% of the students at Northern State own an iPod is best categorized as no fallacy.

This statement is very true and consistent with the facts presented in the passage.

A fallacy is a mistaken belief usually based on biased arguments.

Total number of students sampled = 200

Number of iPod owners = 150

Percentage of iPod owners = \frac{number of iPod owners}{Number of sample} x 100

Percentage of iPod owners = \frac{150}{200} x 100 = 75%

We see that it is consistent to say that at least, 50% of the students in the sample are iPod owners.

How are the direction of force and the direction of motion related in work of an object?
GuDViN [60]
Newton's Third Law States that Every Action Has an Equal and Opposite Reaction. To stop or slow down an object, a force must be applied in the direction opposite to that of the object's motion. Exerting a force results in an equal force in the opposite direction (like the recoil a person feels when firing a gun)
