Answer:

The equivalent resistance of the three resistors is 18 ohms.

Explanation:

The value of three resistors are 6 ohms.

We need to find the equivalent resistance of the resistors. In series combination, the equivalent resistance is given by :

R = R₁ + R₂ + R₃ +.....

Put all the values,

R = 6+6+6

R = 18 ohms

Hence, the equivalent resistance of the three resistors is 18 ohms.

Answer:

A microwave with a frequency of 5*10¹⁰ hertz has a period of 2*10⁻¹¹ seconds.

Explanation:

Frequency is the number of vibrations that occur in a unit of time. Its unit is s⁻¹ or hertz (Hz).

The period is the time that elapses between the emission of two consecutive waves. In other words, it is the time it takes for a complete wave to pass a reference point. The period (T) is simply the inverse of the frequency (f):

[tex]T=\frac{1}{f}[/tex]

In this case, f=5*10¹⁰ Hz. So, replacing in the definition of period T:

[tex]T=\frac{1}{5*10^{10} Hz }[/tex]

Solving:

T= 2*10⁻¹¹ seconds

A microwave with a frequency of 5*10¹⁰ hertz has a period of 2*10⁻¹¹ seconds.

A microwave with a frequency of 5*10¹⁰ hertz has a period of 2*10⁻¹¹ seconds.

The fequency is defined as the number of cycles achieved by the any wave it is expressed in hertz.

Frequency is the number of vibrations that occur in a unit of time. Its unit is s⁻¹ or hertz (Hz).

The period is the time that elapses between the emission of two consecutive waves. In other words, it is the time it takes for a complete wave to pass a reference point. The period (T) is simply the inverse of the frequency (f):

[tex]T=\dfrac{1}{f}[/tex]

In this case, f=5*10¹⁰ Hz. So, replacing in the definition of period T:

[tex]T=\dfrac{1}{5\times 10^{10}}=2\times 10^{-11}\ Sec[/tex]

A microwave with a frequency of 5*10¹⁰ hertz has a period of 2*10⁻¹¹ seconds.

Thus a microwave with a frequency of 5*10¹⁰ hertz has a period of 2*10⁻¹¹ seconds.

Answer:

1. The specific heat of the meatal is approximately 0.266 J/(g·°C)

2. 46.6334 kJ

Explanation:

1. The given mass of the sample of metal, m = 110.0 g

The temperature change of the metal when heat is added, ΔT = 10.0°C

The amount of head that was added, ΔH = 70.0 Calories = 292.88 Joules

The formula for heat heat capacity of a material is given as follows

Q = m × c × ΔT

Where;

Q = The quantity of heat added = 292.88 Joules

m = The mass of the material = 110.0 g

ΔT =  The temperature change = 10.0°C

c = The specific heat capacity of the material

We get;

c = ΔH/(m × ΔT)

Which gives;

c = 292.88 J/(110.0 g × 10.0°C) ≈ 0.266 J/(g·°C)

2. The given mass of aluminum, m = 550.0 g

The initial temperature of the aluminum, T₁ = 14.0°C

The final temperature of the aluminum, T₂ = 108.0°C

The specific heat of aluminum, c = 0.902 J/(g·°C)

We get;

Q = m × c × (T₂ - T₁)

Q = 550.0 g × 0.902 J/(g·°C) × (108.0°C - 14.0°C) = 46,633.4 joules = 46.6334 kJ

The heat that must be supplied to 550.0 g of aluminum pan to raise the temperature of the pan from 14.0°C to 108.0°C, Q = 46.6334 kJ.

Q.1 - V = u + at

u = 0, a = g = 9.8, t = 1

V = 0+9.8*1 = 9.8 m/s

Q 2- In horizontal position the velocity remains same hence a= dv/t, since change in velocity is zero the acceleration also equal to zero

Q.3- After neglecting the air resistance at 45° angle the maximum range is obtained.

let's prove, consider the range have maximum angle at θ, now range is given by

R = u²Sin2θ/g where sin2θ can we written as 2sinθ.cosθ.

Now the range value is directly proportional to the product of sin & cos of firing angle & this maximum value is obtained at 45°

Q.4 The range of two angle will be same if and only if they give 90° on addition.

20+x = 90,

x = 90-20 = 70°

Q.5 The motion with constant acceleration is known as uniformly accelerated motion.

Answer:

Explanation:

1.

u=0m/s

v=?

a=9.8m/s²

t=1sec

now

we have

v=u+at

v=0+9.8*1

v=9.8m/s

3.

angle is measured in sin and cos angle where maximum angle's value is gained by 45°

4.

we have

range

R=[tex]\frac{u²sin2\theta}{g}[/tex]

For

angle =20°

R1=[tex]\frac{u²sin2*20}{g}[/tex].......[1]

another angle be [tex]\theta[/tex]

R2=[tex]\frac{u²sin2\theta}{g}[/tex].......[2]

since R1=R2

By comparing we get

Sin40=Sin([tex]2\theta[/tex])

Sin(180-40)=Sin([tex]2\theta[/tex])

we

140=[tex]2\theta[/tex]

C. Photosynthesis

Explanation:

Photosynthesis is a process by which plants and photosynthetic bacteria obtain their food in presence of sunlight from water and carbon dioxide. They produce glucose as the food and oxygen is emitted as the byproduct. The equation for photosynthesis is - 6H2O+6CO2 → C6H12O6 + 6O2

Thus, the correct answer is 'C.Photosynthesis.'

Answer:

T₂ = 1937.68 N

Explanation:

First, we will calculate the weight of the object:

[tex]W = mg = (478\ kg)(9.81\ m/s^2)\\W = 4689.18\ N[/tex]

Now, we will calculate the resultant tension in the ropes. Since the ropes are perpendicular. Therefore,

[tex]T = \sqrt{T_1^2+T_2^2}\\[/tex]

where,

T = Resultant Tension

T₁ = Tension in rope 1

T₂ = Tension in rope 2

According to the given condition tension in the first rope is 2.2 times the tension in the second rope:

T₁ = 2.2 T₂

Therefore

[tex]T = \sqrt{(2.2T_2)^2 + T_2^2}\\\\T = 2.42T_2[/tex]

Now, the weight of the object must be equal to the resultant tension for equilibrium:

[tex]T = W\\2.42T_2 = 4689.18\ N\\\\[/tex]

T₂ = 1937.68 N

Answer:

(This will depend on the type of fuel, I will assume that the fuel is petrol)

First, let's find the expected energy consumption in the US for the next 10 years.

We know that in one year, a person consumes 3.5*10^11 joules.

There are 310,000,00 people on the US

Then the total consumption in one year is:

310,000,000*3.5*10^11 joules = 1.085*10^20 J

In 10 years the consumption is 10 times the consumption of a single year, then the expected energy consumption in the US for the next 10 years is:

10*1.085*10^20 J = 1.085*10^21 J

Now let's find the mass of fuel required.

We know that a liter of petrol has 31,536,000 joules of energy,

And a liter of petrol weights 0.75 kg

To find the number of liters of petrol that we need, we need to find the quotient between the expected energy consumption in the next 10 years and the energy of a single liter of petrol, this is:

N = (1.085*10^20 J)/(31,536,000 j) = 3.44*10^13

We will need  3.44*10^13 liters of petrol.

And the total mass of petrol will be:

M = 3.44*10^13*0.75 kg = 2.58*10^13 kg of fuel.
