Answer:
P = 22000 kg. m/s
Explanation:
Given data;
Mass of elephant = 2000 Kg
Velocity = 11 m/s
Momentum = ?
Solution:
Momentum is the product of mass and velocity of an object.
It can be calculated from given formula:
P = mv
P = momentum
m = mass
v = velocity
Now we will put the values in formula.
P = 2000 Kg × 11 m/s
P = 22000 kg. m/s
Answer:
molecules
Explanation:
Remember 1 mol is equal to Avogadro's number

Mendeleev organized his table by atomic mass, rather than atomic radius. He was able to extrapolate where certain undiscovered elements should be on the table based on that.
For example, he said that since Calcium has mass of 40g and Titanium has a mass of 48 g, there must be some element between them with atomic mass of 44 g. That was later discovers to be scandium.

<h2>Answer:</h2>
Correct option is B.
B. To relate the type of box material to the warmth of air within the box.
<h2>Explanation:</h2>
Kate gathered three boxes of the same size made of different materials: glass, clear plastic, and aluminum painted black. She placed them on a window sill in the sun for an hour and then measured the warmth of the air in each box. She actually did this to relate the type of box material to the warmth of air within the box.
