<span>The theory concerning global climate change is that carbon and oxygen are combining to form co2 causing global climate change. Predictions are that they will be positive and negative effects, positive effects are they produce more crops and cold related deaths. Some negatives are damage to crops, rising of sea level, spread of disease and other things.</span>

Train cars are coupled together by being bumped into one another. Suppose two loaded train cars are moving toward one another, t
NemiM [27]

Answer:

their final velocity is 0.091 m/s

Explanation:

Given;

mass of the first train, m₁ = 138,000 kg

mass of the second train, m₂ = 123,000 kg

initial velocity of the first train, u₁ = 0.288 m/s

initial velocity of the seocnd train, u₂ = -0.131 m/s (opposite direction to the first)

Let their common final velocity after been coupled = v

Apply the principle of conservation of linear momentum;

m₁u₁  +  m₂u₂ = v(m₁  +  m₂)

(138,000 x 0.288)    +    (-0.131 x 123,000)   =   v(138,000 + 123,000)

39,744   -   16,113   =  v(261,000)

23,631 = v(261,000)

v = 23,631 / 261,000

v = 0.091 m/s

Therefore, their final velocity is 0.091 m/s

A stunt driver rounds a banked, circular curve. The driver rounds the curve at a high, constant speed, such that the car is just
Sladkaya [172]

Answer:

option C and D

Explanation:

When a stunt driver is rotating on the banked road the force which is responsible for the centripetal acceleration of the car is Frictional force and the Normal Force.

The Frictional force component of the banked road will protect the car from skidding.

And the normal force component will protect the car from toppling inward due to centripetal force acting on it.

Hence, the correct answer is option C and D

Describe how the amount of heat released or absorbed related to specific heat capacity and amount of it? A) Amount of heat absor
Grace [21]
The correct answer is
<span>C) Amount of heat absorbed or released is doubled if quantity is doubled. If a different substance with half the specific heat capacity is used, the amount of heat absorbed or released is cut in half. 

In fact, the amount of heat released or absorbed is given by:
</span>Q=m C_s \Delta T
<span>where 
m is the mass of the substance
Cs is the specific heat capacity of the material
</span>\Delta T is the change in temperature
<span>
We can see that Q is directly proportional to both m (mass, or quantity of the substance) and Cs (specific heat capacity). So if the quantity (m) is doubled, the amount of heat (Q) is doubled as well. Similarly, if the specific heat capacity (Cs) is cut in half, the amount of heat (Q) is cut in half as well.</span>
