The equation for momentum is p = mv, where p is momentum, m is mass, and v

Physics
1 answer:
Tasya [4]3 years ago
3 0

Answer:

p = mv, where p is momentum, m is mass, and v is velocity.

a. ) m = 12kg v = 14m/s

Momentum (p) = mv

= 12kg × 14m/s

= 168kg•m/s

b.) momentum (p) = 35 kg•m/s

velocity = 3m/s

p = mv

make m the subject

divide both sides by v

we get

m = p/v

Therefore m is

m = 35 kg•m/s / 3m/s

m = 11.67kg

Therefore the mass of the object is 11.67kg

Hope this helps

What is the final temperature in degrees centigrade of 100g of water at 30 c if it is mixed with 50 g of water at 0?
natka813 [3]

Answer:

<em> The final temperature = 293 K or 20 °C</em>

Explanation:

Heat gained by water at 0°C = heat lost by water at 30°C

c₁m₁(T₃ - T₁) = c₂m₂(T₂-T₃).......................... Equation 1

Making T₃ the subject of the equation,

T₃ = (c₂m₂T₂ + c₁m₁T₁)/(c₁m₁+c₂m₂)............. Equation 2

Where m₁ =mass of water at 0°C, c₁ = specific heat capacity of water at 0°C , c₂ = specific heat capacity of water at 30°C,  m₂ = mass of water at 30°C, T₁ = initial temperature of water at 0°C, T₂ = initial temperature of water at 30°C, T₃ = final temperature.

<em>Given: m₁ = 50 g = (50/1000) kg = 0.05 kg, m₂ = 100 g = (100/1000) kg = 0.1 kg., T₁ = 0°C = 273 K, T₂ = 30°C = (30+273 )= 203 K</em>

<em>Constants: c₁ = c₂ = 4200 J/kg.K</em>

<em>Substituting these values into equation 2,</em>

<em>T₃ = (4200×0.1×303 + 4200×0.05×273)/(4200×0.1 + 4200×0.05)</em>

T₃ = (127260 + 57330)/(420+210)

T₃ = 184590/630

T₃ = 293 K.

<em>Therefore the final temperature = 293 K or 20 °C</em>

Describe how energy can be converted from one form to another in a wind-up toy.
tresset_1 [31]
The idea of a mechanical device, like a wind up toy, is to take take advantage of the laws of thermodynamics in order to perform some kind of work.

In the case of a wind up toy, mechanical energy (winding the handle) is stored as potential energy in an internal spring. This creates a state of 'low entropy' in the toy since work was done to concentrate energy in the spring.

The natural tendency of the spring is to unwind and distribute it's energy in a more disordered fashion, thereby increasing entropy and following the laws of thermodynamics.

The mechanism inside the toy is engineered to focus the flow of energy being delivered by the spring into a specific mechanical motion (Kinetic Energy), then sound (air pressure) and finally heat (thermal energy).
