What are 4 physical properties for the carrots

Answer:

No, because a scientific law is always absolutely true, no matter what a vote could not change a scientific law. People can vote how fast the speed of light is per second, but light will always be the speed it is no matter what.

The time between two new Moon phases or two full Moon phases is 29.5 days. ... The difference of 29.5 and 27.3 is that while the Moon is orbiting the Earth, the Earth is moving along in its orbit so it takes longer for the Moon to reach the same position relative to the Sun.

So the correct option is C as it would be crossed at many points

Hence, the same would be relevant

Answer:

v₃ = 1.334 m/s

Explanation:

This problem can be solved using the law of conservation of momentum:

[tex]m_{1}u_{1} + m_{2}u_{2} + m_{3}u_{3} = m_{1}v_{1} + m_{2}v_{2} + m_{3}v_{3}\\[/tex]

m₁ = mass of bullet = 8.73 g = 0.00873 kg

m₂ = mass of first block = 1201 g = 1.201 kg

m₃ = mass of second block = 1606 g = 1.606 kg

u₁ = initial speed of bullet = 345 m/s

u₂ = initial speed of first block = 0 m/s

u₃ = initial speed of second block = 0 m/s

v₁ = final speed of bullet = v₃ (since the bullet is embedded in second block)

v₂ = final speed of first block = 0.714 m/s

v₃ = final speed of second block = ?

Therefore,

[tex](0.00873\ kg)(345\ m/s)+(1.201\ kg)(0\ m/s)+(1.606\ kg)(0\ m/s)=(0.00873\ kg)(v_{3})+(1.201\ kg)(0.714\ m/s)+(1.606\ kg)(v_{3})[/tex]

[tex]3.0118\ kg.m/s - 0.8575\ kg.m/s = (1.6147\ kg)(v_{3})\\\\v_{3} = \frac{2.1543\ kg.m/s}{1.6147\ kg} \\[/tex]

v₃ = 1.334 m/s

The electrical energy consumed in boiling the water is 0.0788 kWh

Explanation:

Given;

mass of the water, m = 600 g = 0.6 kg

power rating of the kettle, P = 1500 W = 1.5 kW

specific heat capacity of water, c = 4,200 J/kg⁰C

density of water, = 1000 kg/m³

time taken to boil the water, t = 3 mins + 9 s = (3 x 60s) + 9 s = 180 s + 9 s = 189 s = [tex]189 \ s \times \frac{1 hr}{3.600 \ s} = 0.0525 \ hr[/tex]

The electrical energy consumed in boiling the water is calculated as;

E = P x t

E = 1.5 kW  x 0.0525 hr

E = 0.0788 kWh

Therefore, the electrical energy consumed in boiling the water is 0.0788 kWh

The correct answer D: all of the above

Answer:

a change of position in relation to another object.

Explanation:

Motion can be defined as a change in the location (position) of a physical object or body with respect to a reference point.

This ultimately implies that, motion would occur as a result of a change in location (position) of an object with respect to a reference point or frame of reference i.e where it was standing before the effect of an external force.

A reference point refers to a location or physical object from which the motion (movement) of another physical object or body can be determined.

Mathematically, the motion of an object is described in terms of acceleration, time, distance, speed, velocity, displacement, position, etc.

Hence, motion is a change of position in relation to another object.

For refraction , the formula is

sin i / sin r = μ₂ / μ₁

where light is travelling from medium 1 to 2 having refractive index of μ₁ and μ₂ . Angle of incidence in medium 1 is i and angle of refraction in medium 2 is r .

Here i = 70°, r = 37°

μ₁ = 1.8 ,μ₂ = ?

sin70 / sin 37 = μ₂ / 1.8

.939 / .602 = μ₂ / 1.8

1.56 =  μ₂ / 1.8

μ₂ = 2.81 .

The value of refraction index for the second medium will be  [tex]\mu_2=2.16[/tex]

Every material has a different refractive index. The refracted index of any material shows that the light is refracted by how much angle.

So like for water its value will be different also for glass its value will be different.

Now it is given in the question that

Angle of incidence [tex]i=70^o[/tex]

Refractive index of the first medium [tex]\mu_1=1.8[/tex]

Angle of refraction [tex]r=37^o[/tex]

Now from snells law

[tex]\dfrac{Sin \ i}{Sin \ r} = \dfrac{\mu_2}{\mu_1}[/tex]

[tex]\dfrac{Sin70}{Sin37} = \dfrac{\mu_2}{1.8}[/tex]

[tex]\mu_2= \dfrac{Sin70\times1.8}{Sin37}[/tex]

[tex]\mu_2=2.16[/tex]

Thus the value of the refraction index for the second medium will be  [tex]\mu_2=2.16[/tex]

To calculate resistance, we will use the formula:

R = ρl / A

where ρ(rho) is the resistivity of the material, l is the length of the wire and A is the cross-sectional area

We are given:

Length of wire (l) = 0.65 m

Diameter of wire (d) = 2 mm

Material of wire: Copper

Some important conversions:

- radius of the wire = diameter/2

 radius = 2 mm/2 = 1 mm  OR 1 * 10⁻³m

Calculating the cross-sectional area:

Cross-sectional area is the area of the circle at the end of the wire.

Cross-sectional area = π(r²)

Area = π(1 * 10⁻³)²                                         [replacing the value of r]

Area = π * 10⁻⁶ m²

Calculating the resistance:

using the formula mentioned before:

R = ρl / A

R = [tex](1.7 * 10^{-8}ohm*m ) * \frac{0.65 m}{3.14 * 10^{-6}m^{2}}[/tex]        [resistivity of copper = 1.7 × 10⁻⁸ Ωm]

R = 3.52 * 10⁻³ (approx)

Answer:

3.5 × 10⁻³ Ω

Explanation:

The resistance of a conductor is calculated by the formula:

Let's start by converting the diameter of the copper wire to meters.

Since we want the radius of the cross-section, we will divide .002 m by 2.

The radius of the copper wire is .001 m. We can calculate the area of the circular cross-section by using the formula:

The area of the cross-section is π · 10⁻⁶ m².

The length of the wire is 0.65 m long. We do not have to convert units for the length of the wire since it is already in the SI units: meters.

Assuming the copper wire is at 20°C, we know that its resistivity is 1.7 · 10⁻⁸ Ω · m.

Using these three variables, we can solve for R in the formula for electric resistance.

Substitute these values into the equation.

Notice how the unit m² cancels out, leaving us with Ω (units of electrical resistance).

The electric resistance of a copper wire 0.65 m long with a radius of .001 m is .0035 ohms (Ω), or 3.5 × 10⁻³ Ω.

Answer:

F=ma

a=F/m=20/5=4 m/s^2

Answer:

The options are not given, so i will answer in a really general case.

There are two equations that describe how mass affects the motion of an object.

The most generical one, Newton's second equation of motion.

This says that:

F = m*a

Force equals mass times acceleration.

Remember that acceleration tells us how the motion of an object changes as time passes.

So if we isolate the acceleration we get:

a = F/m

Here you can see that the mass is in the denominator, so, for a fixed force F, if we increase the mass of the object, the acceleration will decrease, which means that as more mass has an object, "harder" is to accelerate it.

Now from an energy point of view.

The kinetic energy (the motion energy of a moving object) is written as:

T = (1/2)*m*(v^2)

where:

m = mass

v = velocity.

Here, for a fixed velocity v, if we increase the mass, we also increase the kinetic energy.

This means that if we have two objects, one with a small mass m, and the other with a larger mass M, and we want to give both objects the same velocity v, we will need more energy for the object with more mass.

So in general we can conclude that mass "opposes" to the motion.

Now, we also can define the term "testable"

A hypothesis is testable if we can think of an experiment to test it, if there is no experiment, then the hypothesis is not testable.
