Answer:
Is your question asking for the muzzle velocity of the bullet?
Explanation:
I will assume it does
The bullet travels horizontally to the target in the same amount of time it falls 2.3 cm from vertical rest
s = ½at²
t = √(2s/g) = √(2(0.023) / 9.8) = 0.0685118...s
v = d/t = 47/0.0685118 = 686.01242...
v = 690 m/s
Answer:
n=770,880.
Explanation:
Given that
P= 2200 MW
Power of wind farm = 0.4 or 40%
So the power produce by wind farm = 0.4 x P
P'=0.4 x 2200 MW
P'=880 MW
P'=880,000 KW
We know that
1 year = 365 days
1 day = 24 hr
So
1 year = 365 x 24 hr
1 year = 8760
So the energy produce in one year
E= 8760 x P'
E= 8760 x 880,000 KW
Given that average house hold use 10,000 KW-hr
So lets take total n number of house hold use power
E= n x 10,1000
n=770,880.
Answer:10. Describe Career Connection. Career Connection is an FCCLA national program that guides students to link their options and skills for success in families, careers and communities.
The string that will break first depends on the weight of the block or bar subjected to such string.
According to Hook's law, the force applied to an elastic material is directly proportional to the extension of the material.
F= kx
where;
- <em>F is the force applied to the object = weight of the object</em>
For given two identical strings, the string that will break first depends on the mass of the bar and the block.
- If the bar is heavier than the block, then the string subjected to the bar will break first.
- On the other hand, if the block is heavier than the bar, then the string subjected to the block will break first.
Thus, the string that will break first depends on the weight of the block or bar subjected to such string.

Answer:
48 m/s
Explanation:
Given:
Δx = 250 m
v₀ = 19 m/s
a = 3.9 m/s²
Find: v
v² = v₀² + 2aΔx
v² = (19 m/s)² + 2 (3.9 m/s²) (250 m)
v ≈ 48 m/s
