32. The angle of incidence for the waves illustrated
below is 45°, what is the angle of reflection?

Answer:

we can't balance this because there are no atoms of oxygen in the product side

Answer:

long stapler

Explanation:

Answer: 3.26 s

Explanation:

Given

The ball is projected upward with a velocity  [tex]u=16\ m/s[/tex]

Using the equation of motion

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

Here, displacement is zero as the ball returns to its initial position

[tex]\Rightarrow 0=16\times t-0.5\times g\times t^2\\\Rightarrow t(16-0.5\times 9.8\times t)=0\\\text{i.e.}\ t=\dfrac{16}{4.9}=3.26\ s[/tex]

the velocity of the ball at any instant is given by

[tex]v=u+at\\v=16-9.8t[/tex]

Answer:

0.5 m

Explanation:

From the question given above, the following data were obtained:

Mass (m) = 0.060 kg

Period (T) = 1.4 s

Lenght (L) =?

NOTE:

1. Acceleration due to gravity (g) = 10 m/s²

2. Pi (π) = 3.14

The length of the pendulum can be obtained as follow:

T = 2π√(L/g)

1.4 = 2 × 3.14 × √(L/10)

1.4 = 6.28 × √(L/10)

Divide both side by 6.28

1.4 / 6.28 = √(L/10)

Take the square of both side

(1.4 / 6.28)² = L/10

Cross multiply

L = 10 × (1.4 / 6.28)²

L = 0.5 m

Therefore, the length of the pendulum is 0.5 m

The distance will be = 14.85 m

A region around a charged particle or object within which a force would be exerted on other charged particles or objects.

given :

Charge (q)= 2.45*[tex]10^{-6}[/tex] C

Electric field (EF) =  100 N/C

to find = ? distance (r)

Electric field = 1/4π∈o * (q/[tex]r^{2}[/tex])

         100      = 9 * [tex]10^{9}[/tex] *  ( 2.45*[tex]10^{-6}[/tex] / [tex]r^{2}[/tex])

          [tex]r^{2}[/tex] = 220.5

          r= [tex]\sqrt{220.5}[/tex]

          r = 14.85 m

The distance will be = 14.85 m

Answer:

Motors are the most common application of magnetic force on current-carrying wires. Motors have loops of wire in a magnetic field. When current is passed through the loops, the magnetic field exerts torque on the loops, which rotates a shaft. Electrical energy is converted to mechanical work in the process

Answer: The answer is C.

Explanation:Just took the quiz

The statement about the relationship between rates of reaction and concentration of reactants true is reactions are slower when there is lower concentration of reactants.

The chemical reaction is the reaction between two reactants which led to the formation of products.

The products are substances which forms after reaction. The reactants are the substances which are original materials.

Oxygen is needed for the reactions that cause artifacts to decay in the ocean.

Some ancient shipwrecks have been well-preserved deep in the ocean.

Reviewing the information in the data table, we conclude that reactions are slower when there is lower concentration of reactants.

Thus, the correct option is C.

Answer:

I think you are looking for the velocity, so the answer is 38.5 m/s

Explanation:

Velocity is giving by displacement/time. North will be positive and South will be negative, George travels 750 meters then travels -250 meters his displacement is then 750 - 250 or 500 meters. Divide that by 13 seconds to get 38.5 m/s.

Answer:

3m/s

Explanation:

momentum=mass x velocity

to find velocity...

we change subjects and make velocity the subject,thus , velocity=momentum/mass

v=12/4 =3m/s.

They are both eletro-magnetic waves,  they are both outside of the range humans can see with our eyes. Infrared waves can can carry enough energy to give heat to objects.  There is a lot of Infrared light that is put out by a fire and we feel that as the heat.  Radio waves can be used to carry other signals like when we listen to the radio.  

Explanation:

Answer:

Both infrared and radio waves are longer than visible light and are not considered harmful to humans.Infrared light is how remote controls communicate with electronics like televisions and stereos, while radio waves are how cell phone signals are transmitted.
