If an object has two forces acting on it, how can the net force equal 0?

Answers

Answer 1

Answer:

Check explanation.

Explanation:

Net force is essentially the sum of the forces enacting upon an object. One example of net force is gravity and normal force. It is commonly accepted that every object has a force acting upon it, even if it is stationary. To give an example, the weight of an object has a force upon the earth but the earth pushes back, essentially meaning that the object will not sink.

A 8 g of iron shot is added to a graduated cylinder containing 46 mL of water. The water level rises to the 49 mL mark, from this information, calculate the density of iron

Answers

Answer:

The answer is 2.67 g/mL

Explanation:

The density of a substance can be found by using the formula

[tex]density = \frac{mass}{volume} \\[/tex]

From the question

mass of iron = 8 g

volume = final volume of water - initial volume of water

volume = 49 - 46 = 3 mL

We have

[tex]density = \frac{8}{3} \\ = 2.666666...[/tex]

We have the final answer as

2.67 g/mL

To celebrate a victory, a pitcher throws her glove straight up into the air with an initial velocity of 6.0 m/s. What is the maximum height of the glove? (Show work)

Answers

Answer:

h = 1.8 m

Explanation:

The initial velocity of the glove, u =- 6 m/s

We need to find the maximum height of the glove. Let it is equal to h. Using equation of kinematics. At the maximum height v = 0

[tex]v^2-u^2=2ah[/tex], h is the maximum height and a = -g

[tex]0^2-(6)^2=2\times (-10)\times h\\\\h=\dfrac{36}{20}\\\\h=1.8\ m[/tex]

Hence, it will go up to a height of 1.8 m.

An inclined plane is 10.0 m long and 2.5 m high. What is the mechanical advantage?

Answers

Answer:

MA = 4

Explanation:

In order to solve this problem, we must use the definition of the ideal mechanical advantage, which tells us that it is equal to the relationship of the inclined distance over the height with respect to the level of the ground

MA = L / h

where:

MA = mechanical advantage

L = Length of the inclined plane = 10 [m]

h = elevation = 2.5 [m]

MA = 10/2.5

MA = 4

Using our knowledge of physics... If we know that the moving man travels 10 meters, has an initial velocity of 0 m/s and an acceleration of 1 m/s, use the equation d = vi t + 1/2 a t^2 to solve for time.

Answers

Answer:

t= 4.5s

Explanation:

vi=0m/s

a= 1m/s

d=10m

10m= 0(t) + 1/2(1m/s)(t^2).    0xt cancels out, 1/2 of 1= .5

10m=  .5m/s(t^2)   Divide both sides by .5

20m= t^2.  Take square root of each side

Square root of 20 is 4.472135954999579

sig figs, t= 4.5 s

T=4.5s is the correct answer I think

how far will a 600 kg boat travel in 12 s if there is a constant 900 N force on it and it starts from rest?​

Answers

Answer:

Distance, S = 108 meters.

Explanation:

Force is given by the multiplication of mass and acceleration.

Mathematically, Force is;

[tex] F = ma[/tex] ............equation 1

Where;

F represents force measured in Newton. m represents the mass of an object measured in kilograms. a represents acceleration measured in meters per seconds square.

Given the following data;

Since the boat is starting from rest, initial velocity, u = 0

Mass, m = 600kg

Time, t = 12s

Force, F = 900N

Substituting into equation 1, we have;

[tex] 900 = 600*a[/tex]

[tex]a = \frac{900}{600}[/tex]

Acceleration, a = 1.5 m/s²

T

To solve for distance, we would use the second equation of motion;

[tex] S = ut + \frac {1}{2}at^{2}[/tex]

Substituting the values into the equation, we have;

[tex] S = 0(12) + \frac {1}{2}*1.5* 12^{2}[/tex]

[tex] S = 0 + 0.75* 144[/tex]

Distance, S = 108m

Therefore, the distance covered by the boat is 108 meters.

Answer:

Sling Psychrometer

Explanation:

A sling psychrometer measures relative humidity through the process of evaporation. It contains two thermometers. The cloth around one of the thermometers is wetted and slung around in the air so the moisture evaporates, which has a cooling effect. The relative humidity is then calculated using the difference in temperature for the two thermometers.

A. Semiconductors form a path for the electrons that are released by the photoelectric effect.

C. Semiconductors serve as a source of electrons to form an electrical current.

What is Photoelectric effect?

Photoelectric effect, phenomenon in which electrically charged particles are released from or within a material when it absorbs electromagnetic radiation.

When the semiconductor is exposed to light, it absorbs energy and transfers it to the material, due to which energy reaches to negatively charged particle (electron), which allows the electron to flow in the material as electric current .

hence , correct option will be :

A. Semiconductors form a path for the electrons that are released by the photoelectric effect.

C. Semiconductors serve as a source of electrons to form an electrical current.
