Answer:
The equation that will express this result os
h = 0 = vy t - 1/2 g t^2 so the net height traveled by the bullet is zero
vy t = 1/2 g t^2
vy = 1/2 g t
vy = 1/2 * 9.8 * t you could use -9.8 to indicate vy and g are in different directions
tx = sx/ vx = 46.4 / 471 = .0985 sec time to travel up and down to original height
th = .0985 / 2 = .0493 sec time to reach maximum height
vy = g ty = 9.8 * .0493 sec = .483 m/s initial vertical speed
Sy = vy t - 1/2 g t^2 = .483 * .0493 - 1.2 9.8 (.0493^^2)
Sy = .0238 - 4.9 ( .0493)^2 = .0238 - .0119 = .0119 m
Height to which bullet will rise - if the gun is aimed at this height then in .0985 seconds the bullet will fall to zero height
Check: .483 / 9.8 = .0493 time to reach zero vertical speed
total travel time = 2 * .0493 = .0986 sec
471 * .0986 = 46.4 m total distance traveled by bullet
Answer:
So, this is not the answer because I suck like that (hehe >:3) but here's some helps.
Explanation:
1. The magnitude of the net force acting on an object is equal to the mass of the object multiplied by the acceleration of the object as shown in the formula below.
2. If the net force acting on an object is zero, then the object is not accelerating, and is in a state known as equilibrium.
3. This will be were you use the info I gave to figure it out. I hope this wasn't completely unhelpful.
Answer:
Frequency, 
Explanation:
Given that,
The wavelength of the x-rays, 
We need to find the frequency of an x-ray. All electromagnetic wave travel with a speed of light. It is given by the formula as :
f is the frequency
So, the frequency of an x-ray is 
. Hence, this is the required solution.
Answer:
Explanation:
For this problem, we can use Boyle's law, which states that for a gas at constant temperature, the product between pressure and volume remains constant:
which can also be rewritten as
In our case, we have:
is the initial pressure
is the initial volume
is the final pressure
Solving for V2, we find the final volume:
