a 20 of of ice at 0c is dropped into water at boiling point, specific heat capacity of water =4200 J/kg•c, sepesific latent heat
Contact [7]

Answer:

15 KJ

Explanation:

The quantity of heat (Q) required is given as:

Q = mcΔθ + mL

where m is the mass of ice, c is its specific heat capacity, L is its specific latent heat andΔθ is the change in temperature.

Given: m = 20g, temperature of ice = 0^{o} C, specific heat capacity of water = 4200 J/kg^{o} C, latent heat of fusion of ice = 3.3 x 10^(5) J/kg, temperature of water = 100^{o} C.

Q = m (cΔθ + L)

   = 0.02(4200 x (100) + 330000)

   = 0.02(420000 + 330000)

  = 0.02 (750000)

Q = 15000

Q = 15000 Joules

Q = 15KJ

The quantity of heat needed to complete the conversion is 15 KJ.

A satellite is orbiting earth at a distance of 35.0 kilometers. The satellite has a mass of 500 kilograms. What is the force bet
Alika [10]

Answer:

F = 4856.32 N

Explanation:

Given,

A satellite is orbiting earth at a distance from Earth surface, h = 35000 m

The mass of the satellite, m = 500 Kg

The radius of the Earth, R = 6.371 x 10⁶ m

The mass of the Earth, M = 5.972 x 10²⁴ Kg

The gravitational constant, G = 6.67408 x 10 ⁻¹¹ m³ kg⁻¹ s⁻²

The force between the Earth and the satellite is given by the formula

                                    F = GMm/(R+h)²  N

Substituting the values in the above equation

        F = (6.67408 x 10 ⁻¹¹ X 5.972 x 10²⁴ X 500) / (6.371 x 10⁶ + 35000)²

                                        = 4856.32 N

Hence,  the force between the planet and the satellite is, F = 4856.32 N

A car of mass m=1000kg is traveling at speed v and brakes. The skid marks are 20m long and the coefficient of kinetic friction i
scoray [572]

Answer:

v = 14 m/s

  = 31.3 mph

The answer would be the same if the mass of the car were 2000 kg

Explanation:

Let V be the final velocity of the car after skidding, and v be the initial velocity of the car. Let a be the acceleration of the car and Δx be the distance the car travels after applying brakes (length of the skid marks). Let Fk be the force of friction between the tyres and the road. Let N be the normal force exerted on the car and μ be the co efficient of kinetic friction.

V^2 = v^2 + 2×a×Δx

Now V, the final velocity is zero as the car stops

0 = v^2 + 2×a×Δx

v^2 = -2×a×Δx

v =√-2×a×Δx    .....*

Now applying Newton's Second Law

Fnet = m×a

-Fk = m×a

-μ×N = m×a

-μ×m×g = m×a (The mass cancels out)

a =  -μ×g

Substituting the value of a back to equation *

v = √-2×(-μ×g)×Δx  

v = √-2×(-0.5×9.8)×20

v = 14 m/s

Therefore the speed the car was travelling with v = 14 m/s

which is equal to 31.3 mph

Now if you were to change the mass of the car to 2000 kg the value for v would still be the same. As it is seen above mass cancels out so it does not influence or affect the value of the velocity obtained.

Explain how the principle of uniformitarianism would help geologists determine the source of a layer of particular igneous rock
HACTEHA [7]

Explanation:

The principle of uniformitarianism was proposed by James Hutton, a Scottish geologist to explain geologic processes and how they relate in space.

According to the principle "the present is the key to the past and geologic process occurring today have occurred in times past. ".

  • Saddled with this knowledge, geologists can understand and unravel how rocks form and how the earth has been sculpted.
  • Today, in some places on earth, we see volcanic activities.
  • Such a place is on the Hawaiian Islands where hot plumes are coming to the surface.
  • In like manner, the lava cools and solidifies to form new volcanic basalt.  
  • Using this knowledge, any geologist can unravel any igneous rock.
  • From the activities in Hawaii, we know that past igneous rocks must have been formed by the cooling and solidification of magma.
  • This the tenet of the uniformitarian principle.
