Answer:

m = 35 g

Explanation:

The specific heat of a material can be calculated by the following formula:

[tex]C = \frac{Q}{m}\\[/tex]

where,

C = Specific Heat of Wax = 220 J/g

Q = Amount of Heat Supplied by the Heater = 7700 J

m = mass of wax melted = ?

Therefore,

[tex]220\ J/g = \frac{7700\ J}{m}\\\\m = \frac{7700\ J}{220\ J/g}\\[/tex]

m = 35 g

Answer:Single-Replacement, synthesis, decomposition, combustion.

Explanation:

Had to get it wrong to find out

Redox reactions include Single-replacement, synthesis, decomposition, composition Reactions. Hence option B is correct.

Redox reaction is type of reaction in which oxidation number participating molecules changes. Redox reaction involves two types of the reaction oxidation and reduction. these two reaction take place simultaneous. Oxidation is the loss of electrons and reduction is the gain of electrons.

Oxidation is nothing but addition of oxygen and loss of hydrogen and reduction is loss of oxygen and gain of hydrogen.

Redox reactions include Single-replacement, synthesis, decomposition, composition Reactions.

The oxidation half-reaction is: H₂ → 2H⁺ + 2e⁻

The reduction half-reaction is: F₂ + 2e⁻ → 2F⁻

Hence option B is correct.

Explanation:

it says venus is often named as the earth's twin because both the planets share a similar size, surface composition and have an atmosphere with a complex weather system. But if you go in depth, the earth is just a little bit bigger than venus and both the planets move in opposite direction of eachother

Answer:

Explanation:

Using the formula

v = fλ

v is the speed

f is the frequency

λ is the wavelength

Given the following

v = 332m/s

Frequency is the number of oscillation completed in one second. Since 332 waves passes through a medium in one second, hence the frequency us 222 Hertz

From the formula

λ = v/f

λ = 332/332

λ = 1m

Hence the wavelength is 1m

Answer:

7.5 grams

Explanation:

From the question,

(R/R')ᵇ = 2ᵃ.................... Equation 1

Where b = half life, R = Original mass of iodine, R' = Remaining mass of Iodine after disintegration, a = Total time taken.

⇒ R/R' = 2ᵃ/ᵇ............... Equation 2

Given: R = 60 grams, a = 24 days, b = 4 days

Substitute these values into equation 2

60/R' = 2²⁴/⁸

60/R' = 2³

R' = 60/2³

R' = 60/8

R' = 7.5 grams

Explanation:

l = Length of ladder = 8.57 m

m = Mass of ladder = 21.4 kg

F = Force on ladder = 258 N

[tex]\alpha[/tex] = Angular acceleration = [tex]1.63\ \text{rad/s}^2[/tex]

g = Acceleration due to gravity = [tex]9.81\ \text{m/s}^2[/tex]

Net torque is given by

[tex]\tau=lf-\dfrac{l}{2}mg\\\Rightarrow \tau=8.57\times 258-\dfrac{8.57}{2}\times 21.4\times 9.81\\\Rightarrow \tau=1311.5\ \text{Nm}[/tex]

The net torque acting on the ladder is [tex]1311.5\ \text{Nm}[/tex].

Answer:

O N

Explanation:

Upthrust = Volume of object * density of fluid * acceleration due to gravity

Upthrust = 4.0 m3 *  1000 kg/m3 * 10 m/^2

Upthrust = 40, 000 N

Upthrust = Weight in air - Weight in water

Weight in air = 40,000 N

Weight in water = Weight in air - Upthrust

Weight in water = 40,000 N - 40,000 N

Weight in water = 0 N

Explanation:

Mid-ocean ridges, also known as mid-oceanic ridge is a mountain range made by plate tectonics under the water.

The magma created at a divergent boundary where two tectonic plates meet due to the rise of convection currents in the Earth's mantle which is beneath the oceanic crust results in the uplifting of the ocean floor.

Answer:

60,000m

Explanation:

Convert km/h to m/s by multiplying with 1000/3600.

Convert hours to seconds by multiplying with 3600.

Because displacement is a vector quantity and deals with the shortest distance between points, simply plug it into the equation s=vt.

Answer:

Thrust = 200 N

Explanation:

The engine thrust can be found by using the following formula:

[tex]Thrust = mv[/tex]

where,

m = mass flow rate of the fuel = 0.05 kg/s

v = velocity of ejected gases = 4000 m/s

Therefore, using the given values in the equation, we get:

[tex]Thrust = (0.05\ kg/s)(4000\ m/s)[/tex]

Thrust = 200 N

Answer:

mirrors bounce back light but lenses absorbs light

Mirrors and lenses compare in their interaction with light is that Mirrors bounce light from their surfaces; lenses do not. Hence option B is correct.

Reflection is the change of direction of the wave at the interface which separates two media. it get incident on the other media and get return to the same media is called as reflection. Common examples include the reflection of light, sound and water waves.

Mirror is a type of glass to which a silver layer is coated on the back side and on the silver layer any type of paint is painted.

We can see that in the dark room when we incident light on the mirror, the direction of the light changes at the point of the incidence. in the scientific language we can say that light has reflected from the surface of the mirror. in this case  angle of incidence is always equal to angle of reflection. Light get bounce off from the mirror into same medium as it was incident.

convex lens focuses all the light falling on it to a focus of the lens and concave lens diverges all the light, it do not bounce back the light.

Hence option B is correct.

Answer:

15 grams

Explanation:

9 sugar cubes + 2 teaspoons of baking soda + 2 grams of the sugar cubes each + 3 grams of baking soda = 15g.

The total mass of the reactants used is 24 grams.

A reactant is a substance that undergoes a chemical change or reaction with another substance in a chemical reaction. It is one of the starting materials that are transformed or converted into one or more new substances called products. Reactants are typically written on the left-hand side of a chemical equation, while the products are written on the right-hand side.

In some cases, reactants may be in different phases or states of matter, such as a solid, liquid, gas, or aqueous solution. The identification and measurement of the reactants involved in a chemical reaction are important in understanding the underlying chemistry and predicting the outcomes of the reaction.

Here In the  Question,

The total mass of sugar cubes used is:

9 sugar cubes x 2 grams/sugar cube = 18 grams

The total mass of baking soda used is:

2 teaspoons x 3 grams/teaspoon = 6 grams

So, the total mass of the reactants (sugar cubes and baking soda) used in the experiment is:

18 grams + 6 grams = 24 grams.

Therefore, 24 grams are utilized as the total mass of the reactants.

Answer:

v = 17.30 m / s

Explanation:

For this exercise we will use Newton's second law

at the bottom of the loop and stopped

           ∑ F = 0

           N-W = 0

           N = W

            W = 770 N

the mass of the body is

            W = mg

             m = W / g

            m = 770 / 9.8

            m = 78.6 kg

on top of the loop and moving

           ∑ F = m a

           N + W = m a

note that the three vectors go in the same vertical direction down

the centripetal acceleration is

           a = v² / r

we substitute

           N + W = m v² / r

           v = [tex]\sqrt{(N+W) \frac{r}{m} }[/tex]

let's calculate

          v = [tex]\sqrt{ (350+770) \frac{21}{78.6} }[/tex]

          v = 17.30 m / s

Answer:

0.66 degrees

Explanation:

The computation of the angle of the third dark interference is shown below:

The condition of the minima is

Path difference = (2n +1) × [tex]\lambda[/tex]÷ 2

For third minima, n = 2

Now

xd ÷ D = (2 × 2 + 1) × [tex]\lambda[/tex]÷ 2

d tan Q_3 = 5[tex]\lambda[/tex] ÷ 2

tan Q_3 = 5[tex]\lambda[/tex] ÷ 2d

Q_3 = tan^-1 × (5[tex]\lambda[/tex] ÷2d)

= tan^-1 × (5 × 580 × 10^-9) ÷ (2 × 0.000125)

= 0.66 degrees

The molecules move from one side to another across the concentration gradient by breaking weaker bonds among the atom into stronger bonds. This is done to decrease the overall kinetic energy to become a more stable molecule.

The kinetic strength of the molecules consequences in random movement, causing diffusion. In simple diffusion, this method proceeds without the useful resource of a transport protein. it is the random motion of the molecules that reasons them to move from a place of excessive attention to a place with decreased awareness.

The molecules in a gas, a liquid, or a strong are in consistent movement due to their kinetic electricity. Molecules are in steady movement and collide with each different. those collisions cause the molecules to move in random guidelines. over time, however, greater molecules may be propelled into the less concentrated place.

The majority of the molecules flow from better to decrease awareness, although there can be some that circulate from low to excessive. the general (or net) motion is consequently from high to low concentration.
