How many seconds would an Olympic skier take to race down a 2500 meter course going 250 m/sec?
Answers
Answer:
10 seconds
Explanation:
Hope this is right and that it helps.
You see if the skier is going 250 meters a second 250 times 10 is 2500 so it would take the skier 10 seconds.
Answer:
10 sec.
Explanation:
distance = 2500 meters
velocity = 250 meter/second
time = distance / velocity
= 2500 meters
250 meter/second
= 10 sec.

mud mass attached = 0.700 Kg
speed of door = 14 m/s
angular speed of door = ?
conservation of angular momentum
initial angular momentum is equal to final momentum
Answers
Answer:
momentum = mass x velocity
Explanation:
So ultimately, find the mass of the object (be careful since this is not the same as weight. Weight is your gravitational pull to the earth. This means that your weight different amounts on different planets. But mass stays the same on all planets, it's what most people call their weight.) and then find the velocity (2 meters/second north, etc.)
Now you can apply this to your problem
B. The side of Magnet A that's repelled by Magnet B's south pole must be Magnet A's north pole.
C. The side of Magnet A that's attracted to Magnet B's south pole must be Magnet A's north pole.
D. The side of Magnet A that's repelled by Magnet B's north pole must be Magnet A's south pole
Answers
Like poles of 2 magnets Repel each other and unlike poles attract each other. so the answer would be C. the side of magnet A that's attracted to Magnet B's South pole must be Magnet A's North pole.
With what velocity does it hit the ground?
The acceleration of gravity is 9.8 m/s
Answers
Final answer:
Using the principles of free fall motion, it can be determined that a tennis ball dropped from a height of 1.16 meters would hit the ground with a velocity of 4.8 m/s.
Explanation:
The objective here is to calculate the initial velocity of the tennis ball just before it hits the ground. This is a physics question related to free fall motion. We will use the equation of motion, v^2 = u^2 + 2as, where 'v' is the final velocity, 'u' is the initial velocity, 'a' is the acceleration, and 's' is the distance. In our case, the initial velocity (u) is 0 because the ball is dropped, not thrown downwards.
The acceleration (a) is the acceleration due to gravity, which is -9.8 m/s² (it's negative because it acts downwards). The distance (s) will be the drop height, which is -1.16 m (it's negative because we're considering downwards as negative direction). Therefore, the equation becomes (v)^2 = 0 + 2*(-9.8 m/s²)*(-1.16 m). Solving this we get v = √(2*9.8*1.16) m/s = 4.8 m/s. So, the tennis ball hits the ground with a velocity of 4.8 m/s.

In one molecule of (NH4)2SO4 or ammonium sulfate, there are two nitrogen atoms.
Explanation:
The molecule (NH4)2SO4 is known as ammonium sulfate. This molecule is composed of two ammonium ions (NH4) and one sulfate ion (SO4). The ammonium ion consists of one nitrogen atom (N) and four hydrogen atoms (H). Because the formula indicates there are two ammonium ions (as shown by the subscript '2'), this means the overall molecule of ammonium sulfate contains two nitrogen atoms.
