What is the formula for preventing a collision?.

If we stand near a campfire and we feel the heat without touching it is convection method, heat is coming through radiation.

In thermodynamics, heat has a very precise definition that differs from how we generally use the word. When two systems with various surface temperatures come into touch with one another, heat is the thermal energy that is transmitted. The letters q or Q stand for heat, and the unit of measurement for heat is joules.

Heat is sometimes referred to as a process quantity since it is defined in the context of a process through which energy can be conveyed. The heat that a hot cup of coffee delivers to your palm may be debated, but the heat that the cup of coffee holds is not. Another noteworthy quality is heat..

If the floor were not frictionless, the sphere's angular speed would change and increase until the sliding between the sphere and the floor came to an end. As a result, correct option is C.

When something moves over or rolls over another solid object, there is friction. Even though friction force can be advantageous, such as the traction needed to move without slipping, they also present a sizable amount of resistance to motion.

Friction between alloys appears to be primarily caused by the attraction forces, also called as stickiness, between the contact zones of the surfaces, which are always microscopically unequal. As the defects of the rough surface rub up against the softer surface, the "welded" seams are torn apart and friction is produced.

The corresponding values of the temperatures in 98.6°F and 102°F in Celsius scale are 37°C and 38.89°C

There are three temperature scales in use , Fahrenheit, Celsius and Kelvin. Fahrenheit temperature scale is a scale based on 32 for the freezing point of water and 212 for the boiling point of water, the interval between the two is 180.

In Celsius scale the freezing point is 0°C and the melting point is 100°C. The difference is 100

The conversion of fahrenheit to Celsius scale is given by the formula C= 100( F-32)/180

Where F is the fahrenheit value of the temperature and C is the Celsius value

Therefore, for 98.6°F, C = 100(98.6-32)/180= 6660/180= 37°C

The 7 stages of the rock cycle are weathering, erosion and transport, deposition of sediment, burial and compaction, melting, uplift and deformation and metamorphism.

Weathering is a process of breaking down of rocks into smaller particles. Factors like temperature extremities, water and biological involvement of nature play an important role.

Erosion is a process of breaking down of rocks into sand-like particles. In the previous stage, water was only present as a factor for reactions to take place, while in erosion it acts as a transporting agent too.

Sediment is the constant deposition of small particles of sand, pebbles, that are broken down from rocks.

Burial and compaction happens when the sand particles are sedimented, they create layers which are soon covered by another layer of new sediments and the process goes on.

As soon as the rocks reach the bottom of the earth, the temperature rises and so does the pressure.

The process of forming a crust of earth upwards due to natural forces causing movement in the tectonic plates is called uplifting.

The heat in joules transferred by a chemical reaction to the reservoir of a calorimeter containing 105 g of dilute aqueous solution is 1757.28 J.  

What is calorimeter?

Calorimeter is the device used to measure the heat during electrical, mechanical and chemical reactions and also to calculate heat capacity of the materials.

The heat transferred to a reservoir of a calorimeter can be calculated by,

Initial temperature (T1) = 21° C

Final temperature (T2) = 25° C

Change of temperature (ΔT) = T2 -T1 = 25 - 21 = 4° C.

Q = MC ΔT

where Q is the amount of heat transferred, C is the specific heat and ΔT is the change in temperature.

Q = 105g x 4.184 J/g° C x 4° C = 1757.28 J

At Calvin cycle, temperature has a greater effect compared to light intensity.

Temperature regulates the rate of photosynthesis. The rate of photosynthesis increases with increased temperature. This is due to the fact that photosynthesis is a chemical reaction that is increased by temperature. At higher temperatures, the enzymes simply stop working and become denatured.

Furthermore, the temperature has an impact on the cycle. Because it relies on enzymes, temperatures that are either too high or too low will have an impact.

Meanwhile, a plant cannot photosynthesise efficiently if there is insufficient light even if there is enough of water and carbon dioxide and the temperature is appropriate. Increasing the intensity of the light raises the pace of photosynthesis until some other factor—a limiting factor—runs out.

The equal resistance of the circuit is 10 Ω.

The current through each resistor is 3 A, 1 A, 2 A.

The power used by 5 Ω resistor is 45 watt.

Calculation:

Let us find out

Total resistance:

R = [tex]\frac{(4+2)X12}{(4+2)+12}[/tex]

R = [tex]\frac{12 X 6}{18}[/tex] = 4

So, total resistance

[tex]R_{eq}[/tex] = R + 1 + 5 = 4+5+1 = 10 Ω

Now in second circuit

Using kirchoff's law

30 = 1I + 4I+ 5I

I = [tex]\frac{30}{10}[/tex] = 3 A

So, current through

i) 1 Ω is 3 A

ii) 5 Ω is 3 A

iii) So, I = [tex]I_{1}[/tex] + [tex]I_{2}[/tex] = [tex]\frac{V}{12}[/tex] + [tex]\frac{V}{6}[/tex] = [tex]\frac{V}{4}[/tex]

 ∴ 3 = [tex]\frac{V}{4}[/tex] ,  V = 12

So, [tex]I_{1}[/tex] = 1 A and [tex]I_{2}[/tex] = 2 A

Now, let us find out

the power used by 5 Ω resistance

i.e., P = IV

I = current

V = potential difference

V = IR = 3 × 5 = 15 V

So. power p= 15 × 3 = 45 watt.

This failure or this maximum force that the beam can withstand can be found out by bending moment diagram. According to this diagram, the failure occurs at the mid-point of the beam. If the force is uniform or acting on the mid-point of the beam.

If the force is anywhere except at the mid-point then the failure occurs at the point of application of the force. The maximum force is present at the point of application and from the nearest end, the force linearly increases.
