Answer:
The correct answer is a
Explanation:
At projectile launch speeds are
X axis vₓ = v₀ = cte
Y axis = v_{oy} –gt
The moment is defined as
p = mv
For the x axis
pₓ = mvₓ = m v₀ₓ
As the speed is constant the moment is constant
For the y axis
p_{y} = m v_{y} = m (v_{oy} –gt) = m v_{oy} - m (gt)
Speed changes over time, so the moment also changes over time
Let's examine the answer
i True
ii False. The moment changes with time
The correct answer is a
Answer:
4 quarts = 3.784 L
Explanation:
We have given in the question,
1 quart equals about 0.946 L
1 quart = 0.946 L
thus, for finding value of 4 quarts multiply 4 on both the sides of the above equation.
4 × 1 quart = 4 × 0.946 L
4 quarts = 3.784 L
Hence, in the 4 quarts of milk contains 3.784 L of milk.
Answer:
512
Explanation:
Given sequence:
1/8, 1/2, 2, ...
Unknown:
The 7th term of the geometric sequence = ?
Solution:
To solve this problem, we apply the formula below;
Sₙ = arⁿ⁻¹
a is the first term
r is the common ratio
n is the nth term
r = = = 4
Input the parameters and solve;
Sₙ = x 4⁷⁻¹
Sₙ = x 4⁶ = 512
