Answer: tortoise
Explanation:
Given the following :
Speed of tortoise = 1m/s
Speed of hare = 3m/s
Mass of hare = 5kg
Mass of tortoise = 20kg
Momentum = product of Mass and velocity
Momentum of hare = mass of hare × Velocity of hare
Momentum of hare = 5kg × 3m/s = 15kgm/s
Momentum of tortoise = mass of tortoise × Velocity of tortoise
Momentum of tortoise = 20kg × 1m/s = 20kgm/s
Therefore, tortoise has a greater momentum than hare.
The complete question is;
The gravitational force between two objects is ______ proportional to the products of the masses and _______ proportional to the square of the distance between them.
Answer:
First dash is directly
Second dash is inversely
Explanation:
From Newton's law of gravitation the gravitational force is given by the equation;
F = GMm/r²
Where:
F is gravitational force
M and m are two masses representing the two objects
r is the distance between them
G = universal gravitational constant
Thus, if we are to write it in proportion format, we will have;
F ∝ Mm/r²
From this proportion relationship, we can see that the Gravitational force is directly proportional to the products of the two masses and inversely proportional to the square of the distance between them.
infiltration and evaporation
Answer:
p_k=\sqrt{p_x^2+p_y^2}}
Explanation:
Apply the momentum in each direction knowing that the impact is at the same time for the pieces so
So the momentum in the other piece can be find knowing that
So:
To find the velocity knowing the mass
Answer:
Yes, it is. The summers and the winters are getting warmer. Also in cold places like Alaska, the temperatures are rising.
