The answer I am pretty sure would be B. Weight
Answer:
2.53 m/s
Explanation:
From the law of conservation of momentum,
For an Elastic collision,
Total kinetic energy before collision = Total kinetic energy after collision
Ek₁ = 1/2mv²+1/2m'v'²................. Equation 1
Where Ek₁ = total kinetic energy before collision, m = mass of the first cart, v = final velocity of the first cart, m' = mass of the second cart, v' = final velocity of the second cart.
Given: Ek₁ = 96 J, m = 10 kg, m' = 2 kg, v' = 8 m/s.
Substitute into equation 1 and solve for the value of v.
96 = 1/2(10)(v²)+1/2(2)(8²)
96 = 5v²+64
5v² = 96-64
5v² = 32
v² = 32/5
v² = 6.4
v = √6.4
v = 2.53 m/s
Hence the final speed of the 10 kg mass = 2.53 m/s

Adiabatic rate is used to describe the change in temperature as a result of the rising or the sinking of an air parcel.
Knowing that the dry adiabatic rate of change for unsaturated air is 10°C/1000 m means that the temperature of the unsaturated air parcel would increase (get warmer) as the air parcel sinks and will decrease (get cooler) as the air parcel rises.
Hope this helps :)
Data charts would use descriptive statistics to show accurate reading measured throughout the lab. Charts and graphs can also be used to show the progress and result of the lab.
